DY6 Metals Ltd (ASX: DY6, “DY6” or the “Company”) is pleased to report the results from its recent metallurgy sampling program at the Tundulu REE & Niobium carbonatite project in Malawi.
Highlights:
- A total of 63 metallurgical samples were collected from 37 sample locations along high-grade historic trench (TUTR10) at Tundulu
- Sampling results returned up to a high of 3.35% TREO and 27.5% P2O5 over the sampled 83m length of trench TUTR10:
- an exciting component of the sampling results is the average HREO, being 13% of the TREO basket
- undetectable to very low levels of deleterious elements including mercury, lead and cadmium in the phosphorus (P) rich rocks confirms the exceptional grade quality of the phosphate at Tundulu; and
- the sampling is representative of the mineralised Bastnaesite and Apatite carbonatite rock types exposed within the trench
- Selected samples are being collected to form a 150kg composite to be sent for metallurgical analysis
- 5 bioavailability composite samples were also taken across various historical trenches at Tundulu, targeting phosphate-rich rocks, to determine the solubility of phosphate in the samples and understand its potential for direct fertilization
- Majority of samples showed excellent P solubility (using 2% citric acid) of over 40%, with one returning solubility of 81%. This is above the industry threshold of 9.4% P2O5 solubility using Citric Acid as the reagent in the acid leach process
- 9 samples representing predominant lithologies at Tundulu have been collected and will also be sent to RSC Australia for petrographic examination to validate the historical mineralogical and rock composition
- Samples from the Company’s recent reconnaissance soil and rock chip program at the Ngala Hill PGE, Cu & Ni Project have been submitted to SGS South Africa for analysis, with results expected towards the end of the month
Tundulu REE Project
Tundulu is formed of several hills in a ring around a central vent called Nathace Hill where the majority of the historic surface sampling and drilling was undertaken. The predominant geology at Nathace Hill is REE apatite hosting carbonatites and feldspathic breccia and comprises a large inner agglomerate vent. Mineral rich carbonatite also occurs at Tundulu Hill east of Nathace and Makhanga Hill west of Nathace and is previously unexplored and prospective for REEs and niobium mineralisation.
REE mineralisation remains open towards southern and western directions of Nathace Hill and potentially extends beyond the boundaries of the previously established mineralised area over Tundulu Hill. Initial indications of mineralisation appear to be high in valuable MREEs and low measurable radioactive uranium
(U) and thorium (Th). This compares favourably to Lynas Rare Earths’ Mount Weld Central Lanthanide Deposit where Th and U concentrations in the ore are approximately 660 ppm and 25 ppm respectively.1

A total of 63 metallurgical samples were collected from 37 sample locations along high-grade historic trench (TUTR10) at Tundulu.
Sampling results returned up to a high of 3.35% TREO and 27.5% P2O5 (average of 0.85% TREO and 8.26% P2O5) over the sampled 83m length of trench TUTR10. The average HREO component of the TREO basket was 13%, with high-value heavy rare earth elements Dy & Tb contributing 2.5%. Undetectable to very low levels of deleterious elements including mercury, lead and cadmium in the P-rich rocks confirms the exceptional grade quality of the phosphate at Tundulu.
The sampling is representative of the mineralised Bastnaesite and Apatite carbonatite rock types exposed within the trench. Select samples are being collected to form a 150kg composite to be sent to for metallurgical analysis.
5 bioavailability composite samples were also taken across various historical trenches at Tundulu, targeting phosphate rich rocks. ‘Bioavailability’ is used for analysis on phosphorous rock sources to determine the solubility of phosphate in soils. This analysis is useful in determining whether a particular phosphate rock type is suitable for direct fertiliser applications where the phosphate would be applied directly to the soil for uptake.
The analysis has been undertaken at Nagrom metallurgical and analytical laboratory in Kelmscott, Western Australia under standard atmospheric conditions using 2% citric acid. The majority of samples showed excellent phosphorus (P) solubility of over 40%, with one returning solubility of 81%. The exceptional quality of the phosphate-rich rocks at Tundulu is manifested by their undetectable to very low levels of deleterious elements including mercury, lead and cadmium.
The metallurgical test work will aim to evaluate historical studies undertaken at Tundulu and assess the findings from a 2017 metallurgical report, completed by the previous operators of the licence. The test work will initially focus on validating the beneficiation results achieved by the previous laboratory.
Conducting test work at this early stage enables the Company to ascertain the preliminary viability of producing two product streams: namely a REE commercially saleable concentrate and a mixed phosphate concentrate containing rare earths.

Reconnaissance Sampling Program Commences at Ngala Hill PGE Project to Follow up Historical Targets
HIGHLIGHTS
- Targeted reconnaissance sampling program commences at DY6’s highly prospective PGE, Cu & Ni project at Ngalla Hill, Southern Malawi
- At Ngala Hill, 3 key target zones of palladium rich Pd+Pt+Au+Cu mineralisation have been identified from historical trenching and limited drill testing
- DY6 will undertake a rock chip and soil sampling program to follow up on known high grade areas as well as aiming to expand the zone of mineralisation
- No significant modern exploration including electromagnetics (EM) to target massive sulphides has been undertaken at Ngala Hill
- Trenching by Placer Dome in 2000 included results of:
- 12m at 3g/t PGE+Au; and
- 70m at 1.12g/t PGE+Au, including 8m at 3.3g/t PGE+Au
- The main mineralised zone has only had limited modern drilling
The Company’s CEO, Mr Lloyd Kaiser said:“Our team in Malawi has actively built strong relationships with local communities across our projects and this early engagement at Ngala Hill is setting the foundation between the Company and the community as we prepare to mobilise the geo team and embark on our first exploration campaign at Ngala.”

Background on the Project
The Ngala Hill ultramafic chonolith is an arcuate-shaped intrusion, with dimensions of approximately 2.4km by 0.7km and was intruded into the underlying Proterozoic Basement Complex gneisses. The Ngala Hill Project is characterised by an intrusive ultramafic suite of pyroxenites and hornblende- pyroxenites that intrude basement gneisses. The pyroxenite facies of the ultramafic complex is prospective for platinum group elements (PGEs), predominantly palladium, and associated copper.
Initial work at Ngala Hill in the late 1960s included geochemical sampling programs undertaken by the British and Malawian Geological Surveys. Phelps Dodge started an exploration program for PGEs on Ngala Hill in 1999 with approximately 600 m of trenching. Metapyroxenite and amphibolite with an PGE- gold-copper nickel association was intersected trenching and yielded 1.41g/t Pt+Pd+Au and 1,430 ppm Cu over a length of 64m.
In 2000, Placer Dome confirmed further anomalies with encouraging results received from several trenches including 12m at 3g/t PGE+Au and 70 m at 1.12g/t PGE+Au, including 8m at 3.3g/t PGE+Au.

Heavy Rare Earths & Niobium Explorer DY6 Metals Lists On ASX Following Successful $7M IPO
- $7 million successfully raised via IPO, including $2.5 million from Hong Kong- based cornerstone investors, Zhenshi Group and Zhung Nam New Material Company
- Funds to be used for exploration on three 100%-owned rare earths and critical metals projects in southern Malawi
- Malawi is an attractive and stable mining jurisdiction with proven potential for hosting major rare earth deposits including Lindian Resources’ world class Kangankunde discovery (40km east of the Company’s Machinga Project)
- RC drilling is already underway at the flagship Machinga project, with diamond drilling scheduled to commence next month
- Drilling aims to follow up high grade 2010 results by Globe Metals and Mining (ASX:GBE)§Machinga is enriched in heavy rare earths (Dysprosium and Terbium) and Niobium
DY6’s listing follows a successful initial public offering (IPO), which raised $7 million. As part of this, the Company attracted a combined $2.5 million from Hong Kong-based strategic investors, Zhensi Group (HK) Heshi Composite Materials Co., Limited and Zhung Nam New Material Company Limited.
The funds raised in the IPO will be used primarily for exploration at the Company’s three 100%-owned rare earths and critical metals projects located in southern Malawi, a stable and attractive African jurisdiction with proven potential for hosting major mineral deposits.
DY6 has recently commenced a 5,000m program of reverse circulation and diamond drilling at the flagship Machinga project, only 40km east of Lindian Resources’ Kangankunde carbonatite discovery, which is widely regarded as the world’s best undeveloped rare earths project.
Machinga is particularly enriched with high-value heavy rare earth elements dysprosium and terbium. The project also holds significant niobium and tantalum potential as well.
Non-executive Chairman Dan Smith said: “DY6 has recently started its maiden drill program at the exciting Machinga project. In addition to being a potential source of the critical heavy rare earth elements Dysprosium and Terbium, Machinga also contains significant Niobium mineralisation.
The Company is seeking to emulate the success of Lindian Resources in proving up a major critical minerals project in southern Malawi. We believe the projects and the team we have assembled provide us with an excellent opportunity.”

Six targets have been identified to date within the Machinga North concession and the Company will be following up on previous high grade intercepts from a previous 2010 campaign undertaken by Globe Metals and Mining (ASX:GBE).
DY6’s other projects in southern Malawi, Salambidwe and Ngala Hill, have also been subject to previous exploration: rock chips from Salambidwe returned high grade values of TREO and Nb while soil samples from Ngala Hill and limited previous drilling by Phelps Dodge returned high grade results of Pd, Pt, Au and Cu.
The Company plans to carry out detailed geophysical and geological sampling programs at Salambidwe to aid in defining targets for a maiden drilling campaign towards the end of the year. RC drilling at Ngala Hill is scheduled for around the same time.

- RXDD122: 0.95m @ 13.50 g/t Au from 204.44m
- §These results further demonstrate the continuity of high- grade gold mineralisation along the Youanmi greenstone belt belt, and the potential for resource growth both at depth and along-strike, with discovery potential to the south
- 35,000m Step-up drill campaign well underway with the plan to bring forward ounces and increase the mine plan
The program focused on converting Inferred stopes at Pollard, United North and Youanmi Main to higher confidence Indicated classification and providing material for metallurgical testing for the upcoming Definitive Feasibility Study (DFS) – on track for H2 CY25.
This final consignment of diamond assay results are the fourth batch of assays results returned from the drill program and have been entirely drilled from the Pollard, Youanmi and United North areas (Figure 1).
Rox Resources’ Chief Executive Officer, Phillip Wilding, commented:
“It’s pleasing to round out the 11,000m RD and DD drilling program with another batch of excellent intercepts.
“More importantly, the program has significantly improved our knowledge of the high grade and underexplored Youanmi ore system, and shown that mineralisation remains open at depth.
“Next steps are to convert Inferred areas of the Resource to the higher confidence Indicated classification, and finalise key intercepts of sample material for metallurgical test work to feed into the Youanmi DFS.
“We are excited to have commenced the 35,000m Step-up program to potentially bring forward ounces in the mine plan and significantly increase the size of the Pollard ore zone.”
Youanmi Major Growth Drill program
Resource drilling has focused on converting selected Inferred stopes in the current Mineral Resource of 16.2Mt at 4.4g/t Au for 2.3Moz (Indicated: 10.7Mt at 4.5g/t Au for 1.6 Moz : Inferred 5.5Mt at 4.2g/t Au for 0.7 Moz) 1 to higher confidence Indicated classification at Pollard, United North and Youanmi Main as shown in plan on Figure 1. The drilling has also provided both sample material for metallurgical testing and valuable geological data for the pending Definitive Feasibility Study (“DFS”) planned for second half of 2025.

Outside of the immediate resource area, drilling was also conducted on near-mine exploration and focused on the Youanmi South prospect area, or Paddy’s Lode, first reporting high-grade intercepts in 20232. The drilling at Paddy’s has complimented the Company’s exploration strategy moving south along the Main Lode Shear Zone (MLSZ) and adding additional gold ounces to the Resource. Youanmi South has the potential to grow the Resource above the 103kozpa Production Target outlined in the recently completed Pre-Feasibility Study (“PFS”)3.

Drilling Commenced at Viani in Fiji
HIGHLIGHTS
- The Phase 1, three-hole diamond drilling program has commenced at the Viani Project, Fiji and will test for extensions to the quartz vein gold mineralisation at depth.
- Phase 1 is expected to be completed in early 2025, with plans for additional drilling under the same program dependent on the initial results
- The Viani Project (SPL1513) covers an area of approximately 200km2 and is largely underexplored.
- At the Dakuniba prospect within Viani, low sulphidation epithermal high-grade gold mineralisation has been mapped over >3km strike length.
- Diamond drilling completed by Japan International Cooperation Agency (JICA) in 1995 to 1997 intersected high-grade gold in low sulphidation epithermal quartz veins, including 0.6m @ 27.6 g/t Au.
Alice Queen’s Managing Director, Andrew Buxton said,
With drilling underway, Alice Queen is positioned to test the epithermal gold-style mineralisation identified in historic drilling at the Viani Project. Weather permitting, we anticipate completing the Phase 1, three-hole diamond drilling program in early 2025. Following this, our exploration team will mobilise the drill rig to the Sabeto Project in Fiji to maintain the momentum of this campaign. To deliver timely results to shareholders, we intend to accelerate the analysis of the drill core at ALS Brisbane.”

Details
Geology
The geology of the Viani Project (SPL 1513) comprises olivine basalts and volcaniclastics of the Natewa Volcanic Group which are intruded by andesite sills and dykes. In the 1940s, gold mineralisation was found by local prospectors near the village of Dakuniba. At Dakuniba, low sulphidation style epithermal gold occurs in quartz veins, and silicified rocks along a 3km long NE trending zone.
In 1995-1997, Japan International Cooperation Agency (JICA) drilled six diamond holes at Dakuniba and intersected high-grade gold in chalcedonic, crustiform, colloform banded quartz veins at depths of 50m to 100m below surface (i.e. MJVFV-5 intersected 2.2m @ 11.3 g/t Au, incl 0.6m @ 27.6 g/t Au at 121m downhole). This high-grade gold mineralisation is open in all directions.
Proposed Drill program
The initial Phase 1 drill program at Viani (see Table 1) will comprise three diamond drillholes designed to test continuity to the epithermal gold mineralisation previously intersected in JICA drillhole MJVFV- 5 (2.2m @ 11.3 g/t Au) (see Figure 2). The drilling will test for extensions to the gold mineralisation at depth and along strike.
