Allkem - Mt Cattlin Resource Drilling Update

Allkem Limited (ASX|TSX: AKE the Company ) is pleased to provide an update on the resource extension drilling program currently underway at its Mt Cattlin spodumene operation in Western Australia.

The drilling program consists of three phases as described below:

Phase 1 – drilling within the US$900 2NW pit shell converting resource to reserve (planned 49 holes, 11,120 metres). Underway – ~77% complete.

Phase 2 – drilling to the north and down dip of the US$900 2NW pit shell to test resource extensions outside of the US$900 2NW pit (planned 80 holes, 19,125 metres) and within the US$1,100 pit shell. Underway – ~55% complete.

Phase 3 – drilling in the SW of the mine tenements to test additional targets and prospects (18 holes, 2,440 metres). To be undertaken in late 2022/early 2023.

HIGHLIGHTS

Phase 1 drilling is targeting to convert 3.2Mt of Resource to Reserves. Intercepts within this pit include high grade zones with large thicknesses such as 12m at 2.46% Li ₂ O and 15m at 1.91% Li ₂ O
Phase 2 drilling and assay results demonstrate resource extension potential to the north of the current pit with high grade intercepts in the lower pegmatite, including 9m at 2.98% Li ₂ O and 7m at 1.86% Li ₂ O
Phase 1 and 2 drilling at 2NW pit is on target for completion by end of October and a consultant has been engaged to immediately commence a study to convert mineral resources to Ore Reserves for scheduling, mine planning and detailed pit design
Mt Cattlin's Mineral Resource tonnage recently increased 21% to 13.3Mt @ 1.2% Li ₂ O and 131 ppm Ta ₂ O ₅

INTERIM DRILLING RESULTS

Allkem commenced a three-phase resource extension program in mid-April that targets 147 holes for approximately 32,685 metres of reverse circulation (" RC" ) drilling.

As of 14 September, 81 holes drilled for a total of 19,177 metres were complete and assay results for 47 drillholes were available.

Highlights from the assays of the upper pegmatite include:

Drillhole	From(m)	To(m)	Thickness(m)	Li ₂ O%	Ta ₂ O ₅ ppm
NWRC186	81	89	8	1.41	105

Pegmatite mineralisation to this point generally aligns with the existing geological model and of those assays returned to date and lithia (Li ₂ O) content is consistent with historic (pre-2022) assays in the North West pit area of Mt Cattlin. Given the tendency for "pinch and swell" in pegmatite mineralisation, definitive conclusions are not possible at this stage, however geological logging and assay results to date are highly encouraging.

A typical cross section at northing 224160E (MGA 94) in Figure 1 shows ongoing thick pegmatite development down dip from the US$650 (Ore Reserve) pit shell and the USD 1,100 Whittle shell.

All drill hole collars for assay results are presented in Figure 2 and Appendix: Table 1.

Given the executed orientation of the drilling, assay intercepts reported are broadly true width.

Next steps

The Phase 1 resource infill program at 2NW pit is on target for completion by the end of October and Perth based consultants Entech have been appointed to project manage an open pit, cut-back feasibility level study and execution.

Planning is underway for follow-up reverse circulation and diamond drilling, for the purposes of extension, geotechnical and metallurgical studies.

The study is anticipated to commence in October and aims to convert in-situ mineral resources (as announced on 25 August 2022) to Ore Reserves for scheduling, mine planning and detailed pit design in a NW pit.

Additionally, a scoping study continues to evaluate the potential for either opencut or underground development of further resource extensions from Phase 2 drilling.

On completion of the drilling at the NW pit, the focus will shift to Phase 3 and further definition in the SW part of the reasonable prospects of eventual economic extraction (RPEEE) footprint and lead to programs that test pegmatite continuity in areas previously not included in resource and mineral resource modelling. These programs will continue towards the end of the year and extend onto exploration leases as conditions and permitting allows.

APPENDIX 3 – JORC 2012 TABLE 1 DISCLOSURE

Section 1: Sampling Techniques and Data

MT CATTLIN LITHIUM PROJECT SAMPLING AND DATA
*Sampling techniques*	Nature and quality of sampling (e.g. cut channels, random chips, or specific specialized industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. Aspects of the determination of mineralization that are Material to the Public Report. In cases where ‘industry standard' work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverized to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralization types (e.g. submarine nodules) may warrant disclosure of detailed information.	Pre-2017 Mt Catlin mineralization was sampled using a mixture of Diamond (DD) Reverse Circulation drill holes (RC), rotary Air Blast (RAB) and Open Hole (OH). In the north zone drilling is a 40mE x 40mN spacing and infilled to 20mE to 25mE x 20mN to 20mN in the central zone. In the south the drilling is on a 40mE x 80mN pattern. Drill holes were drilled vertical to intersect true thickness of the spodumene mineralization. A total of 39 DD holes for 1,528.56m, 986 RC holes for 48,763m, 59 OH holes for 1,999m and 23 RAB for 402m had been completed before 2017. The drill-hole collars were surveyed by professional survey contractors. A total of 71 drill holes were surveyed by Surtron Technologies Australia of Welshpool in 2010. Sampling was carried out under Galaxy Resources QAQC protocols and as per industry best practice. RC sample returns were closely monitored, managed and recorded. Drill samples were logged for lithology and SG measurements. Diamond HQ and PQ core was quarter-cored to sample lengths relating to the geological boundaries, but not exceeding 1m on average. RC samples were composited from 1m drill samples split using a two-stage riffle splitter 25/75 to obtain 2kg to 4kg of sample for sample preparation. All samples were dried, crushed, pulverized and split to produce a 3.5kg and then 200g sub-sample for analysis For Li (method AAS40Q), for Ta, Nb and Sn (method XRF78O) and in some cases for SiO2, Al2O3, CaO, Cr2O3, Fe2O3, K2O3, MgO, MnO, P2O5, SO3, TiO2 and V2O5 were analysed by XRF78O. Entire drill-hole lengths were submitted for assay. Drilling 2017-8 From 1m of drilling and sampling, two 12.5% splits are taken by a static cone splitter in calico drawstring bags. This obtains two 2kg to 4kg samples with one being retained as an archive sample and the other submitted for assay, where required an archive bag is used as the duplicate sample. A 4.5-inch diameter rod string is used and the cyclone is cleaned at the end of every 6m rod as caking occurs from the mandatory use of dust suppression equipment. Drilling November 2018 – 2021 Subsequent to 2018 update, 5,912m (41 holes)m of new reverse circulation (RC) and 273.65 of diamond tails (2 holes) has been completed (excluding metallurgical and geotechnical) has taken place. From 1m of drilling and sampling, two 12.5% splits are taken by a static cone splitter in calico drawstring bags. This obtains two 2kg to 4kg samples with one being retained as an archive sample and the other submitted for assay, where required an archive bag is used as the duplicate sample. A 4.5-inch diameter rod string is used and the cyclone is cleaned at the end of every 6m rod as caking occurs from the mandatory use of dust suppression equipment. Drilling April 2022 onwards A total of 81 holes drilled for a total of 19,177 metres and 47 holes remaining planned for a total remaining of 11,155 metres as of 14 September, 2022.
*Drilling techniques*	Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.).	RC drilling hammer diameter was generally 4 & 5/8 inches in early exploration, from 2009 and 2010 the bit diameter was 5 ¼ inches. RC 2017 - 2020 5.25-inch face sampling hammer, reverse circulation, truck mounted or tracked drilling rigs, Three Rivers Drilling, Castle Drilling. Diamond core is generally RC from surface, and either PQ size tails in weathered rock and narrowed to HQ in fresh rock (standard tubing). Core was not oriented as the disseminated and weathered nature of the mineralization does not warrant or allow it. Diamond core is typically for metallurgical test-work. Precollars drilled short of mineralisation. RC 2021 A 5.25-inch face sampling hammer, used in reverse circulation. ASX (Australian Surface Exploration) drillers used for RC (including pre-collars). Diamond 2021 : Wizard Drilling utilised for diamond drilling from surface. HQ size Metallurgical and geotechnical diamond drilling (standard tubing). Two Metallurgical holes were diamond tails from approximately 70m to 80m. Four Geotechnical holes were diamond from surface and two tails from 50-60m depth. RC 2022 PXD, RC drilling, 5 1/3 inch, face sampling hammer.
*Logging*	Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. The total length and percentage of the relevant intersections logged.	All DD, RC and OH (PC) and RAB intervals were geologically logged (where applicable); RQD (DD only), interval weights, recovery, lithology, mineralogy and weathering were recorded in the database. The DD core was oriented using the Ezy-Mark tool and after 2019 using the Reflex ACT electronic orientation tool. Geological logging was qualitative. Recording of interval weights, recovery and RQD was quantitative. All DD core was photographed and representative 1m samples of RC and OH (PC) chips were collected in chip trays for future reference and photographed. All drill holes were logged in full. 2017-2022 logging All drill holes are logged and validated via LogChief/DataShed systems. Stored in MS SQL server database. Assays, standards and control limits are monitored after loading of each batch and reports supplied on demand. All drill holes are logged in full. Different Lithium bearing mineral species and crystal sizes are logged in detail.
*Sub-sampling techniques and sample preparation*	If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. For all sample types, the nature, quality and appropriateness of the sample preparation technique. Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled.	Pre-2016 sampling All fresh rock DD core was quarter-cored using a stand mounted brick saw. Soft, weathered DD core was also sampled quarter-core, using a knife and scoop where applicable and practical. RC samples were collected using a two stage riffle splitter. All samples were dry or dried prior to riffle-splitting. All 2kg 1m drill samples were sent to SGS, dried, crushed, pulverized and split to approximately -75µ to produce a sample less than 3.5kg sub-sample for analysis. Sampling was carried out under Galaxy Resources QAQC protocols and as per industry best practice. Duplicate, blank and standard reference samples were inserted into the sample stream at random, but averaging no less than 1 blank and standard in every 25 samples. Samples were selected periodically and screened to ensure pulps are pulverized to the required specifications. Duplicate quarter-core samples were taken from DD core at random for testing averaging one in every 25 samples. Duplicate riffle-split RC samples were taken at random, but averaging one every approximately 25 samples. The sample sizes are appropriate to the style, thickness and consistency of the mineralization at Mt Catlin. Drilling 2016 (SGS) Core was halved by saw and sample lengths typically 0.5m in length. Sample preparation involved crushing followed by splitting of sample if sample greater than 3 kg using a riffle splitter (SPL26), Dry sample, crush to 6mm, pulverise to 75µm (PRP88) in a LM5 Mill. Drilling 2017-2021 Diamond drilling was typically sawn half core with whole core used for metallurgical test work. Intertek (2017-8) Samples are sorted and weighed. Samples >3kg are riffle split and milled in LM5 to obtain 85% passing 75 Microns. A 400g pulp is taken and a nominal 0.25g sub-sample is fused with sodium peroxide. Nagrom: 2018-2021 RC chips are dried to 105C°, crushed to nominal top-size of 2 mm in a Terminator Jaw crusher using method CRU01. Pulverised up to 3 kg in a LM5 pulveriser mill at 80% or better passing 75µm, using method PUL01. If the sample is greater than 3 kg, the sample is dried, and split with rotary splitter before analysis, Diamond core is dried, crushed in a Terminator Jaw crusher to top size 6.3 mm, and pulverised in a LM5 mill up to 2.5 kg using method CRU01. If the sample is greater than 2.5 kg, the sample is riffle split after drying to reduce the sample size.
*Quality of assay data and laboratory tests*	The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.	Pre-2016 QAQC All samples were dried, crushed, pulverized and split to produce a 3.5kg and then 200g sub-sample for analysis For Li (method AAS40Q), for Ta, Nb and Sn (method XRF78O) and in some cases for SiO2, Al2O3, CaO, Cr2O3, Fe2O3, K2O3, MgO, MnO, P2O5, SO3, TiO2 and V2O5 were analysed by XRF78O. This process involves fusing the sample in a platinum crucible using lithium metaborate/tetraborate flux. For Cs, Rb, Ga, Be and Nb from time to time analysis was by IMS40Q – DIG40Q to ICPMS end. Duplicate, blank and certified reference samples were inserted into the sample stream at random, but averaging one every ~25 samples.Galaxy Resources utilized certified Lithium standards produced in China and one from SGS in Australia, STD-TAN1. Inter-laboratory checking of analytical outcomes was routinely undertaken to ensure continued accuracy and precision by the preferred laboratory. Samples were selected periodically and screened by the laboratory to ensure pulps are pulverized to the required specifications. All QAQC data is stored in the Mt Catlin database and regular studies were undertaken to ensure sample analysis was kept within acceptable levels of accuracy; the studies confirmed that accuracy and precision are within industry standard accepted limits. Umpire analysis performed on pulps at Genalysis and Ultratrace Perth. 2016-QAQC In 2016 Perth SGS were used for a small 6 hole diamond program by General Mining. Samples were digested using a sodium peroxide fusion digest, method DIG90Q and the resultant solution from the digest was then presented to an ICP-MS for the quantification of Li2O, using method IMS40Q. The majority of standards submitted performed within expected ranges with a positive bias observed for two standards. 2017 - 2021 QAQC Samples (including QA/QC samples) were processed by Intertek PLC, Perth laboratory in 2017 and 2018, by utilised method FP1 digest (Peroxide Fusion – complete), MS analytical finish, 22 elements, Li2O detection limit 0.03% Ta2O5 detection limit, 0.2 ppm. Monthly review of QA/QC, which includes blanks, field duplicates, high grade standards and CRM (certified reference materials) and SRM (standard reference materials). FS_ICPMS is a Laboratory Method FP1/MS (mass spectrometry) used to analyze for Cs, Nb, Rb, Ta,Th, and U . FS/ICPES (inductively coupled plasma emission spectroscopy) is Laboratory method FP1/OE used to analyze Al, Fe, K, Li, and Si. Reports include calculated values of oxides for all elements. RC samples and diamond (including QA/QC samples) have been processed by Nagrom Perth, Perth Western Australia. Methods utilised from Lithium and Tantalum are ICP004 and ICP005 (Peroxide Fusion – complete). ICP005 utilises tungsten carbide bowl to reduce iron contamination at exploration and resource development stages (detection limit of 10ppm and 1ppm for Li2O and Ta respectively) Monthly review of QA/QC, which includes blanks, field duplicates, high grade standards and CRM (certified reference materials) ) and SRM (standard reference materials).. All sampling has rigorous QAQC in terms of reference sampling as well as blank and standards introduced into the sample steam. Duplicate field samples show some evidence of high nugget effect. Typically, duplicate pairs plot within acceptable limits. Field duplicates have been submitted at a rate of 1 per 20.5 samples. Standards ASM0343, ASM0340 AMIS0339, OREAS147, OREAS148 and OREAS149. Standards reported only one result outside three standard deviations from 533 assays for Lithium. The vast majority of Tantalum standards reported within three standard deviations. Corse blanks have shown no evidence of systematic contamination from 2016-2021 with results consistently low. 2022 Drilling: Lithium by Peroxide Fusion in Ni crucible with OES at both Intertek and Nagrom. Tantalum by Peroxide Fusion in Ni crucible with MS at Nagrom and Intertek or by XRF at Nagrom. Review of QA/QC, which includes blanks, field duplicates, high grade standards and CRM (certified reference materials) ) and SRM (standard reference materials) are conducted as assays are returned. All sampling has rigorous QAQC in terms of reference sampling as well as blank and standards introduced into the sample steam. Duplicate field samples show some evidence of high nugget effect. Typically, duplicate pairs plot within acceptable limits. Field duplicates have been submitted at a rate of 1 per 20.1 samples. Standards AMIS0339, AMIS0340, OREAS147, OREAS148, OREAS750 and OREAS751. Standards are submitted at a rate of 1 per 25 samples and Blanks after/within high grade zones at a target rate of approximately 1 per 20 samples.
*Verification of sampling and assaying*	The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data.	Pre-2018 Verification An external geological consultant and GXY staff have visually assessed and verified significant intersections of core and RC and PC chips. Several core holes were compared to neighboring RC and PC drill holes. The geological logging of the DD holes supports the interpreted geological and mineralization domains. Studies on assays results from twinned holes showed a close correlation of geology and assays. Primary data is recorded by hand in the field and entered Excel spread sheets with in-built validation settings and look-up codes. Scans of field data sheets and digital data entry spread sheets are handled on site at Galaxy. Data collection and entry procedures are documented and training given to all staff. QAQC checks of assays by Galaxy identified several standards out of control, these were subsequently reviewed and results rectified. No clear and consistent biases were defined by Galaxy during the further investigations into QAQC performances although deviations were noted by Galaxy. 2017-8 Verification CP independently verified drilling, sampling, assay and results from validated, externally maintained and stored database. No adjustments to assay data other than conversion from Li to Li20 and Ta to Ta2O5. 2018 - 2021 Verification The CP independently verified drilling, sampling, assay and results from validated, externally maintained and stored database. No adjustments to assay data other than conversion from Li to Li20 and Ta to Ta2O5. Primary data capture by Maxwell LogChief and management by Maxwell DataShed. Assay data loaded directly from Laboratory supplied .csv files as are downhole and collar surveys. An independent data verification was completed as part of a 2021 Ni-43-101 filing by then then competent person. The CP has verified the drill collar, assay and assay QAQC data.

Section 2: Reporting of Exploration Results

Criteria	JORC Code explanation	Commentary
*Mineral tenement and land tenure status*	Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The security of the tenure held at the time of reporting along with any known impediments to obtaining a license to operate in the area.	Mining Lease M74/244 was amalgamated and awarded on 04/08/2009 and is valid until 23/12/2030 and covers 1830 Ha. The project is subject to normal projects approvals processes as regulated by the WA Department of Mines, Industry and Regulation. The tenement is subject to the Standard Noongar Heritage agreement as executed 7 February 2018. The underlying land is a mixture of freehold property owned by Galaxy and vacant Crown land. The property Freehold title is held by Galaxy Resources or its child subsidiaries.
Exploration done by other parties	Acknowledgment and appraisal of exploration by other parties.	During the 1960's WMC carried out an extensive drilling program to define the extent of t local spodumene bearing pegmatite. The WMC work led onto a further investigation into project feasibility. In 1989 Pancontinental Mining, Limited drilled 101 RC drill holes. In 1990 Pancontinental drilled a further 21 RC drill holes. In 1997 Greenstone Resources drilled 3 diamond holes and 38 RC holes, undertook soil sampling and metallurgical test work on bulk samples from the mine area. Haddington Resources Ltd in 2001 drilled 9 diamond holes for metallurgical test work and undertook further sterilization drilling. Galaxy acquired the M72/12 mining tenement from Sons of Gwalia administrators in 2006.
*Geology*	Deposit type, geological setting and style of mineralization.	The Mount Catlin Project lies within the Ravensthorpe Suite, with host rocks comprising both the Annabelle Volcanics to the west, and the Manyutup Tonalite to the east. The contact between these rock types extends through the Project area. The Annabelle Volcanics at Mt Cattlin consist of intermediate to mafic volcanic rocks, comprising both pyroclastic material and lavas. The pegmatites which comprise the orebodies occurs as a series of sub-horizontal sills, hosted by both volcanic and intrusive rocks, interpreted as a series of westward verging thrusts. Typical coarse grained spodumene (grey-green colour) from the NW pegmatite shown below. The NW pit pegmatites extend from near surface sub-crop to vertical depths of 250-300m and further down dip extensions are interpolated form 2D seismic data generated by previous owners. The pegmatites remain open down dip.
*Drill hole Information*	A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: easting and northing of the drill hole collar elevation or RL (Reduced Level – elevation above sea level in meters) of the drill hole collar dip and azimuth of the hole down hole length and interception depth hole length.	Pre-2017 drilling reported 4 August 2015 by subsidiary GMM (ASX:GMM). Last prior resource and update was August 2022. 2019-2021 drill collars New resource development collar information is presented in Table 1 above. Holes are generally steeply inclined between -80 to -70 degrees to determine true width or due to infrastructure.
*Data aggregation methods*	In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. The assumptions used for any reporting of metal equivalent values should be clearly stated.	Pre-2017 Data Where higher grade zones internal to broader intervals of lower grade mineralization were reported, these were noted as included intervals and italicized. 2019-2021 Drilling New results are reported to a 0.4% cut-of grade (below), minimum 4m width, maximum 1m internal dilution. Only drillholes incorporated into the resource model are reported. 2022 Drilling Minimum cut-off 0.4% Li ₂ O; minimum 4m interval; maximum 2m of internal waste. No metal equivalent values are used.
*Relationship between mineralization widths and intercept lengths*	These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralization with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known').	All intersection grades have been reported previously as length weighted average grades using a 0.4% Li ₂ O lower grade cut-off except where stated. Intersections were calculated allowing a maximum of 2m of internal dilution with no top-cut applied. Cutting of high grades is not required due to nature of the mineralization and grade distribution/estimation. The Mt Cattlin lithium and tantalum mineralization occurs as a thick horizontal to gently dipping pegmatite and generally lies 30 to 200m below the current topographic surface resulting in drill intercepts nearing true widths. 2022 reported intersections are true widths.
*Diagrams*	Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.	Diagrams, both plan and section, are included in the text above.
*Balanced reporting*	Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.	2022 - All significant intersections above 0.4% Li ₂ O have are reported.
*Other substantive exploration data*	Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk sample– size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.	Fe2O3 is modelled with Li and Ta to determine the effect of deleterious chemistry and mineralogy at or near pegmatite contacts and rafts of surrounding country rock with pegmatite.
*Further work*	The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.	Development and extraction of the NW Pit Mineral Resource and Reserve. Ongoing resource development drilling. New geotechnical and metallurgical test work drilling. Resource extension drilling to the SW. Resource update is expected in Q1, 2023 with study work to start Q4, 2022.

Inside Billionaire Gina Rinehart's Key Mining Investments (Updated 2024)

Australian billionaire Gina Rinehart has become a formidable force in the global mining industry.

After taking the helm of her father’s iron ore mining firm Hancock Prospecting in 1993, Rinehart embarked upon a diversification strategy that has vastly expanded her resource empire. Today, Australia’s richest person has investments in many of the world’s most strategic commodities such as lithium, rare earths, copper, potash and natural gas.

One of those investments is Arafura Rare Earths (ASX:ARU,OTC Pink:ARAFF), which even in a low price environment for rare earths has managed to secure nearly AU$1.5 billion in debt financing and is, as of November 2024, pursuing equity financing to advance its Nolans project in the Northern Territory. With a 10 percent equity stake, Rinehart’s Hancock Prospecting is Arafura's largest shareholder.

In addition to Arafura, entrepreneur Rinehart’s investment portfolio also contains other ex-China, green-transition-focused companies such as Australian lithium firm Liontown Resources (ASX:

LTR,OTC Pink:LINRF), as well as rare earths producers MP Materials (NYSE:MP) and Lynas Rare Earths (ASX:LYC,OTC Pink:LYSCF). Rinehart’s role in the acquisition of Azure Minerals’ Andover lithium project in Western Australia alongside lithium giant SQM (NYSE:SQM) also made headlines in May of this year.

SANTIAGO, Chile , Nov. 20, 2024 /PRNewswire/ -- Sociedad Química y Minera de Chile S.A. (SQM) (NYSE: SQM; Santiago Stock Exchange: SQM-B, SQM-A) reported today net loss ^{( [1] ),(2)} for the nine months ended September 30, 2024 , of (US$524.5) million or (US$1.84) per share, compared to US$1,809.5 million or US$6.33 per share reported for the same period last year.

Gross profit ⁽³⁾ reached US$1,033.3 million (29.9% of revenues) for the nine months ended September 30, 2024 , lower than US$2,674.3 million (43.4% of revenues) recorded for the nine months ended September 30, 2023 . Revenues totaled US$3,455.0 million for the nine months ended September 30, 2024 , representing a decrease of 43.9% compared to US$6,155.9 million reported for the nine months ended September 30, 2023 .

The Company also announced net income for the third quarter of 2024 of US$131.4 million or US$0.46 per share, a decrease of 72.6% compared to US$479.4 million or US$1.68 per share for the third quarter of 2023. Gross profit for the third quarter of 2024 reached US$280.8 million , 62.7% lower than the US$753.6 million reported for the third quarter of 2023. Revenues totaled US$1,076.9 million for the third quarter of 2024, a decrease of 41.5% compared to US$1,840.3 million for the third quarter of 2023.

SQM's Chief Executive Officer, Ricardo Ramos , stated, "We are publishing our third quarter 2024 financial results with positive volume growth in almost all of our business lines compared to last year. Fertilizer markets have shown solid market dynamics with a market size recovery. Our Specialty Plant Nutrition volumes grew more than 20% year-on-year while our revenues in this business line increased close to 12%."

He continued, "Iodine demand continued to be strong, leading to an increase in our sales volumes and revenues compared to last year. Prices continued to move up slightly quarter over quarter since the beginning of this year and we have used part of our inventories to answer market needs."

Mr. Ramos further stated, "In lithium, we reported sales volumes of more than 51 thousand metric tons of lithium products, an 18% growth year-on-year, demonstrating strong demand in the market. As anticipated, prices during the third quarter continued their downward trend, with average realized prices 24% lower than the second quarter this year. Although demand continues to grow at a strong pace, mainly driven by strong EV sales growth in China , we continue to see the prices pressured by an oversupply that persists despite the curtailment announcement we have seen over the past few weeks."

Mr. Ramos closed by saying, "Our more than 30-year track record in the lithium market has proved that we have a long-term view in this business. Despite current market prices, we strongly believe in the lithium market and its fundamentals which are highly related to the clean energy transition. SQM is in a strong competitive position and well prepared to continue developing our projects in Chile and abroad to harvest the benefits of this transition."

MT CATTLIN LITHIUM PROJECT SAMPLING AND DATA
*Sampling techniques*		Nature and quality of sampling (e.g. cut channels, random chips, or specific specialized industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. Aspects of the determination of mineralization that are Material to the Public Report. In cases where ‘industry standard' work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverized to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralization types (e.g. submarine nodules) may warrant disclosure of detailed information.	Pre-2017 Mt Catlin mineralization was sampled using a mixture of Diamond (DD) Reverse Circulation drill holes (RC), rotary Air Blast (RAB) and Open Hole (OH). In the north zone drilling is a 40mE x 40mN spacing and infilled to 20mE to 25mE x 20mN to 20mN in the central zone. In the south the drilling is on a 40mE x 80mN pattern. Drill holes were drilled vertical to intersect true thickness of the spodumene mineralization. A total of 39 DD holes for 1,528.56m, 986 RC holes for 48,763m,59 OH holes for 1,999m and 23 RAB for 402m had been completed before 2017. The drill-hole collars were surveyed by professional survey contractors. A total of 71 drill holes were surveyed by Surtron Technologies Australia of Welshpool in 2010. Sampling was carried out under Galaxy Resources QAQC protocols and as per industry best practice. RC sample returns were closely monitored, managed and recorded. Drill samples were logged for lithology and SG measurements. Diamond HQ and PQ core was quarter-cored to sample lengths relating to the geological boundaries, but not exceeding 1m on average. RC samples were composited from 1m drill samples split using a two-stage riffle splitter 25/75 to obtain 2kg to 4kg of sample for sample preparation. All samples were dried, crushed, pulverized and split to produce a 3.5kg and then 200g sub-sample for analysis For Li (method AAS40Q), for Ta, Nb and Sn (method XRF78O) and in some cases for SiO2, Al2O3, CaO, Cr2O3, Fe2O3, K2O3, MgO, MnO, P2O5, SO3, TiO2 and V2O5 were analysed by XRF78O. Entire drill-hole lengths were submitted for assay. Drilling 2017-8 From 1m of drilling and sampling, two 12.5% splits are taken by a static cone splitter in calico drawstring bags. This obtains two 2kg to 4kg samples with one being retained as an archive sample and the other submitted for assay, where required an archive bag is used as the duplicate sample. A 4.5-inch diameter rod string is used and the cyclone is cleaned at the end of every 6m rod as caking occurs from the mandatory use of dust suppression equipment. Drilling November 2018 – 2021 Subsequent to 2018 update, 5,912m (41 holes) of new reverse circulation (RC) and 273.65m of diamond tails (2 holes) has been completed (excluding metallurgical and geotechnical) has taken place. From 1m of drilling and sampling, two 12.5% splits are taken by a static cone splitter in calico drawstring bags. This obtains two 2kg to 4kg samples with one being retained as an archive sample and the other submitted for assay, where required an archive bag is used as the duplicate sample. A 4.5-inch diameter rod string is used and the cyclone is cleaned at the end of every 6m rod as caking occurs from the mandatory use of dust suppression equipment. 2022 Drilling The current drillhole dataset for the project contains 3,232 drillholes, for 175,950 metres, comprised of a combination of reverse circulation (RC), diamond drilling (DD), and RC with a diamond tail (RC_DDT) drillholes. The dominant drillhole type is RC, with over 95% of the metres being from RC drillholes.
			Hole_Type	Count	Metres	% Drillholes	% Metres
			DDH	45	5,437.8	1.4%	3.1%
			RC	3,173	169,037.8	98.2%	96.1%
			RC_DDT	14	1,474.4	0.4%	0.8%
			TOTAL	3,232	175,950	100%	100%

*Drilling techniques*	Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.).		RC drilling hammer diameter was generally 4 & 5/8 inches in early exploration, from 2009 and 2010 the bit diameter was 5 ¼ inches. RC 2017 -2020 5.25-inch face sampling hammer, reverse circulation, truck mounted or tracked drilling rigs, Three Rivers Drilling, Castle Drilling. Diamond core is generally RC from surface, and either PQ size tails in weathered rock and narrowed to HQ in fresh rock (standard tubing). Core was not oriented as the disseminated and weathered nature of the mineralization does not warrant or allow it. Diamond core is typically for metallurgical test-work. Pre-collars drilled short of mineralisation. RC 2021 A 5.25-inch face sampling hammer, used in reverse circulation. ASX (Australian Surface Exploration) drillers used for RC (including pre-collars). Diamond 2021 : Wizard Drilling utilised for diamond drilling from surface. HQ size Metallurgical and geotechnical diamond drilling (standard tubing). Two Metallurgical holes were diamond tails from approximately 70m to 80m. Four Geotechnical holes were diamond from surface and two tails from 50-60m depth. RC 2022 PXD drilling was utilised for RC drilling from surface. HQ size Metallurgical and geotechnical diamond drilling (standard tubing) by Orlando Drilling. Four Metallurgical holes were and three Geotechnical holes were diamond drilled from surface and two diamond tails from 150-160m depth.
*Logging*	Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. The total length and percentage of the relevant intersections logged.		All DD, RC and OH (PC) and RAB intervals were geologically logged (where applicable); RQD (DD only), interval weights, recovery, lithology, mineralogy and weathering were recorded in the database. The DD core was oriented using the Ezy-Mark tool and after 2019 using the Reflex ACT electronic orientation tool. Geological logging was qualitative. Recording of interval weights, recovery and RQD was quantitative. All DD core was photographed and representative 1m samples of RC and OH (PC) chips were collected in chip trays for future reference and photographed. All drill holes were logged in full. 2017-2023 logging All drill holes are logged and validated via LogChief/ Maxwells Geosciences/DataShed systems. Assays, standards and control limits are monitored after loading of each batch and reports supplied on demand. All drill holes are logged in full. Different Lithium bearing mineral species are logged in detail.
*Sub- sampling techniques and sample preparation*	If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. For all sample types, the nature, quality and appropriateness of the sample preparation technique. Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled.		Pre-2016 sampling All fresh rock DD core was quarter-cored using a stand mounted brick saw. Soft, weathered DD core was also sampled quarter-core, using a knife and scoop where applicable and practical. RC samples were collected using a two stage riffle splitter. All samples were dry or dried prior to riffle-splitting. All 2kg 1m drill samples were sent to SGS, dried, crushed, pulverized and split to approximately -75µ to produce a sample less than 3.5kg sub-sample for analysis. Sampling was carried out under Galaxy Resources QAQC protocols and as per industry best practice. Duplicate, blank and standard reference samples were inserted into the sample stream at random, but averaging no less than 1 blank and standard in every 25 samples. Samples were selected periodically and screened to ensure pulps are pulverized to the required specifications. Duplicate quarter-core samples were taken from DD core at random for testing averaging one in every 25 samples. Duplicate riffle-split RC samples were taken at random, but averaging one every approximately 25 samples. The sample sizes are appropriate to the style, thickness and consistency of the mineralization at Mt Catlin. Drilling 2016 (SGS) Core was halved by saw and sample lengths typically 0.5m in length. Sample preparation involved crushing followed by splitting of sample if sample greater than 3 kg using a riffle splitter (SPL26), Dry sample, crush to 6mm, pulverise to 75µm (PRP88) in a LM5 Mill. Drilling 2017-2021 Diamond drilling was typically sawn half core with whole core used for metallurgical test work. Intertek (2017-8) Samples are sorted and weighed. Samples >3kg are riffle split and milled in LM5 to obtain 85% passing 75 Microns. A 400g pulp is taken and a nominal 0.25g sub-sample is fused with sodium peroxide. Nagrom: 2018-2021 RC chips are dried to 105C°, crushed to nominal top-size of 2 mm in a Terminator Jaw crusher using method CRU01. Pulverised up to 3 kg in a LM5 pulveriser mill at 80% or better passing 75µm, using method PUL01. If the sample is greater than 3 kg, the sample is dried, and split with rotary splitter before analysis, Diamond core is dried, crushed in a Terminator Jaw crusher to top size 6.3 mm, and pulverised in a LM5 mill up to 2.5 kg using method CRU01. If the sample is greater than 2.5 kg, the sample is riffle split after drying to reduce the sample size. Intertek 2022-3 Samples are sorted and weighed. Samples >3kg are riffle split and milled in LM5 to obtain 85% passing 75 Microns. A 400g pulp is taken and a nominal 0.25g sub-sample is assayed by Sodium peroxide fusion in a Ni crucible / MS, OES method FP6-Li/OM19.
*Quality of assay data and laboratory tests*	The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.		Pre-2016 QAQC All samples were dried, crushed, pulverized and split to produce a 3.5kg and then 200g sub-sample for analysis For Li (method AS40Q), for Ta, Nb and Sn (method XRF78O) and in some cases for SiO2, Al2O3, CaO, Cr2O3, Fe2O3, K2O3, MgO, MnO, P2O5, SO3, TiO2 and V2O5 were analysed by XRF78O. This process involves fusing the sample in a platinum crucible using lithium metaborate/tetraborate flux. For Cs, Rb, Ga, Be and Nb from time to time analysis was by IMS40Q – DIG40Q to ICPMS end. Duplicate, blank and certified reference samples were inserted into the sample stream at random, but averaging one every ~25 samples. Galaxy Resources utilized certified Lithium standards produced in China and one from SGS in Australia, STD-TAN1. Inter-laboratory checking of analytical outcomes was routinely undertaken to ensure continued accuracy and precision by the preferred laboratory. Samples were selected periodically and screened by the laboratory to ensure pulps are pulverized to the required specifications. All QAQC data is stored in the Mt Catlin database and regular studies were undertaken to ensure sample analysis was kept within acceptable levels of accuracy; the studies confirmed that accuracy and precision are within industry standard accepted limits. Umpire analysis performed on pulps at Genalysis and Ultratrace Perth 2016-QAQC In 2016 Perth SGS were used for a small 6 hole diamond program by General Mining. Samples were digested using a sodium peroxide fusion digest, method DIG90Q and the resultant solution from the digest was then presented to an ICP-MS for the quantification of Li2O, using method IMS40Q. The majority of standards submitted performed within expected ranges with a positive bias observed for two standards. 2017 - 2021 QAQC Samples (including QA/QC samples) were processed by Intertek PLC, Perth laboratory in 2017 and 2018, by utilised method FP1 digest (Peroxide Fusion – complete), MS analytical finish, 22 elements, Li2O detection limit 0.03% Ta2O5 detection limit, 0.2 ppm. Monthly review of QA/QC, which includes blanks, field duplicates, high grade standards and CRM (certified reference materials) and SRM (standard reference materials). FS_ICPMS is a Laboratory Method FP1/MS (mass spectrometry) used to analyse for Cs, Nb, Rb, Ta,Th, and U . FS/ICPES (inductively coupled plasma emission spectroscopy) is Laboratory method FP1/OE used to analyse Al, Fe, K, Li, and Si. Reports include calculated values of oxides for all elements. RC samples and diamond (including QA/QC samples) have been processed by Nagrom Perth, Perth Western Australia. Methods utilised from Lithium and Tantalum are ICP004 and ICP005 (Peroxide Fusion – complete). ICP005 utilises tungsten carbide bowl to reduce iron contamination at exploration and resource development stages (detection limit of 10ppm and 1ppm for Li2O and Ta respectively) Monthly review of QA/QC, which includes blanks, field duplicates, high grade standards and CRM (certified reference materials) and SRM (standard reference materials). All sampling has rigorous QAQC in terms of reference sampling as well as blank and standards introduced into the sample steam. Duplicate field samples show some evidence of high nugget effect. Typically, duplicate pairs plot within acceptable limits. Field duplicates have been submitted at a rate of 1 per 20.5 samples. Standards used are ASM0343, ASM0340 AMIS0339, OREAS147, OREAS148 and OREAS149. Standards reported only one result outside three standard deviations from 533 assays for Lithium. The majority of Tantalum standards reported within three standard deviations. Coarse blanks have shown no evidence of systematic contamination from 2016-2021 with results consistently low. QAQC in 2022-3 is broadly in line with the processes above, assays are by Intertek, Perth and Kalgoorlie. Standards used are OREAS 147, AMIS0341, OREAS 751, OREAS 753, OREAS 148, AMIS0341, AMIS0341, and OREAS 147 to support Sodium peroxide fusion in Ni crucible assay method MS, OES FP6-Li/OM19. This method provides near complete recovery for most samples. Ore grade standards e.g. Oreas 751 reported only four results outside 2 standard deviations from assays for Lithia. The majority of Tantalum standards reported within 2 standard deviations. A figure accompanying this announcement is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/a0a96d56-0609-4c98-a4b7-54a5abe86952 The data is moderately precise.
*Verification of sampling and assaying*	The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data.		Pre-2018 Verification An external geological consultant and staff have visually assessed and verified significant intersections of core and RC and PC chips. Several core holes were compared to neighbouring RC and PC drill holes. The geological logging of the DD holes supports the interpreted geological and mineralization domains. Studies on assays results from twinned holes showed a close correlation of geology and assays. Primary data is recorded by hand in the field and entered Excel spread sheets with in-built validation settings and look-up codes. Scans of field data sheets and digital data entry spread sheets are handled on site at Mt Cattlin. Data collection and entry procedures are documented, and training given to all staff. QAQC checks of assays had identified several standards out of control, these were subsequently reviewed and results rectified. No clear and consistent biases were defined by Galaxy during the further investigations into QAQC performances although deviations were noted by Galaxy. 2017-8 Verification CP independently verified drilling, sampling, assay and results from validated, externally maintained and stored database. No adjustments to assay data other than conversion from Li to Li20 and Ta to Ta2O5. 2018 - 2022 Verification The CP independently verified drilling, sampling, assay and results from validated, externally maintained and stored database. No adjustments to assay data other than conversion from Li to Li20 and Ta to Ta2O5. Primary data capture by Maxwell LogChief and management by Maxwell DataShed. Assay data loaded directly from Laboratory supplied .csv files as are downhole and collar surveys. An independent data verification was completed as part of a 2021 Ni-43-101 filing by then competent person. Data exported from SQL database and verified by the CP. No adjustments are made to assay data.

The property Freehold title is held by Galaxy Resources or its child subsidiaries.
*Exploration done by other parties*	Acknowledgment and appraisal of exploration by other parties.	During the 1960's WMC carried out an extensive drilling program to define the extent of local spodumene bearing pegmatite. The WMC work led onto a further investigation into project feasibility. In 1989 Pancontinental Mining, Limited drilled 101 RC drill holes. In 1990 Pancontinental drilled a further 21 RC drill holes. In 1997 Greenstone Resources drilled 3 diamond holes and 38 RC holes, undertook soil sampling and metallurgical test work on bulk samples from the mine area. Haddington Resources Ltd in 2001 drilled 9 diamond holes for metallurgical test work and undertook further sterilization drilling. Galaxy acquired the M72/12 mining tenement from the Sons of Gwalia administrators in 2006.
*Geology*	Deposit type, geological setting and style of mineralization.	The Mount Catlin Project lies within the Ravensthorpe Suite, with host rocks comprising both the Annabelle Volcanics to the west, and the Manyutup Tonalite to the east. The contact between these rock types extends through the Project area. The Annabelle Volcanics at Mt Cattlin consist of intermediate to mafic volcanic rocks, comprising both pyroclastic material and lavas. The pegmatites which comprise the orebodies occurs as a series of sub- horizontal sills, hosted by both volcanic and intrusive rocks, interpreted as a series of westward verging thrusts. Typical coarse grained spodumene (grey green colour) from the NW pegmatite shown below.

Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. The assumptions used for any reporting of metal equivalent values should be clearly stated.	Pre-2017 Data Where higher grade zones internal to broader intervals of lower grade mineralization were reported, these were noted as included intervals and italicized. 2019-2022 Drilling New results are reported to a 0.3% cut-of grade (below), minimum 4m width, maximum 1m internal dilution. Only drillholes incorporated into the resource model are reported. No metal equivalent values are used.
*Relationship between mineralization widths and intercept lengths*	These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralization with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known').	All intersection grades have been reported previously as length weighted average grades using a 0.3% Li2O lower grade cut-off except where stated. Intersections were calculated allowing a maximum of 2m of internal dilution with no top-cut applied. Cutting of high grades is not required due to nature of the mineralization and grade distribution/estimation. The Mt Cattlin lithium and tantalum mineralization occurs as a thick horizontal to gently dipping pegmatite and generally lies 30 to 280m below the current topographic surface resulting in drill intercepts nearing true widths. All reported intersections in 2023 are approximate true widths.
*Diagrams*	Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.	Diagrams are included in the text above.
*Balanced reporting*	Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.	All significant intersections above 0.3% Li2O have been fully reported in previous releases. 2019-2022 Drilling Drill hole collars and relevant assay details are appended below.
*Other substantive exploration data*	Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk sample– size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.	Fe2O3 is modelled with Li and Ta to determine the effect of deleterious chemistry and mineralogy at or near pegmatite contacts and rafts of surrounding country rock with pegmatite.
*Further work*	The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.	Development and extraction of the NW Pit Mineral Resource and Reserve. Diagrams are illustrated in the text above. Feasibility study work to trade off open pit vs underground options has commenced.
