Nevada Lithium Resources Inc. (CSE: NVLH; OTCQB: NVLHF; FSE: 87K) (“Nevada Lithium” or the “Company”) is pleased to provide an updated mineral resource estimate (“Mineral Resource Estimate”) at its 100% owned Bonnie Claire Lithium Project (the “Project” or “Bonnie Claire”), located in Nye County, Nevada. The Mineral Resource Estimate was prepared by Global Resource Engineering (“GRE”) in accordance with Canadian Institute of Mining and Metallurgy and Petroleum (“CIM”) definitions, as required under National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”) and has an effective date of September 24, 2024. Most notably, the Lower Zone (as defined below) gives an indicated resource of 275.85 million tonnes (“Mt”) at 3,519 parts per million (“ppm”) lithium (“Li”) (5.167 Mt lithium carbonate equivalent (“LCE”)) and 275.85 Mt at 8,404 ppm boron (“B”) (2.318 Mt B), together with an inferred resource of 1,561.06 Mt at 3,085ppm lithium (25.634 Mt LCE).
Nevada Lithium’s CEO, Stephen Rentschler, comments:
“We are excited to announce the impact of the new drilling in the Lower Zone of mineralized lithium and boron at Bonnie Claire. With the significantly increased tonnage and higher grades, Bonnie Claire is potentially unrivaled by other sediment hosted lithium projects in Nevada and is now amongst the largest lithium resources in the world and amongst the highest-grade in Nevada.
Compared to Bonnie Claire’s previous resource report, the new drilling in the Lower Zone has led to a 68% increase in LCE tonnage, at an average grade that has tripled from 1,000 ppm to over 3,000 ppm. It includes intervals where grades exceed 6,000ppm. These increases have occurred using a cut-off grade that has more than doubled to 1,800 ppm. For the first time, we are also able to report a significant high-grade boron resource that we believe further enhances the Project’s value.
The Lower Zone remains open to the NW, NE and SE, for future resource expansion. Furthermore, the new infill drilling has resulted in an indicated resource classification. We are confident that the continuity of the mineralization will allow us to easily upgrade additional resources from the inferred classification into indicated resources and add new inferred resources.
The results from this report will feed directly into ongoing work on an updated Preliminary Economic Assessment (“PEA”) that we are targeting for completion at the end of Q1 2025. This PEA will reflect the increased tonnages and grades reported today. The PEA will also include the metallurgical processes currently being developed by Fluor Enterprises Inc., as reported in our news release dated October 23, 2024.
I would like to offer my congratulations and thanks to Nevada Lithium’s technical team for this tremendous success. Their dedication and vision has led to results that are of global significance and, in my opinion, will lead to future increases in shareholder value.”
Highlights:
- Resources for the deposit have been separated into two zones; a Lower Zone (i.e., mineralization hosted by Lower Claystone and Lower Sandstone units) (the “Lower Zone”) and an Upper Zone (i.e., mineralization hosted by an Upper Claystone unit) (the “Upper Zone”).
- The updated Mineral Resource Estimate includes assays from eleven (11) additional exploration and infill drill holes completed since the 2021 maiden resource estimate. 2023 & 2024 drilling intersected the lower claystone which hosts the high grade (up to 7,160ppm) lithium, and which remains open in three directions. It is reasonably expected that the bulk of inferred resources can be upgraded to indicated through additional infill drilling.
- The Lower Zone gives an indicated resource of 275.85 Mt at 3,519 ppm lithium (5.167 Mt LCE) and 275.85 Mt at 8,404 ppm Boron (2.318 Mt B), together with an inferred resource of 1,561.06 Mt at 3,085ppm lithium (25.634 Mt LCE). This base-case resource is based on a 1,800ppm lithium cutoff, constrained by hydraulic borehole mining (“HBHM”) parameters, and an assumed 60% recovery of the host strata.
- The Upper Zone gives an indicated resource of 188.08 Mt at 1,074 ppm lithium (1.075 Mt LCE) and 152.11 Mt at 1,519 ppm boron (0.231 Mt B), together with an inferred resource of 451.10 Mt at 1,106 ppm lithium (2.655 Mt LCE) and 270.53 Mt at 1,505 ppm boron (0.407 Mt B). This resource is calculated at a 900 ppm lithium cut-off, within a constraining pit shell, and would be mined by conventional open-pit methods
- The 60% HBHM recovery is based purely on a cylindrical cavity and does not account for any improved recoveries from the expected plastic deformation of the deep zone material.
- The updated Mineral Resource Estimate will be included into ongoing work on an updated PEA expected for completion at the end of Q1 2025.

Results and Interpretation
Bonnie Claire consists of a sedimentary package of volcaniclastic origin, laid down in a NW-SE basin striking basin. Lithium and boron mineralization are located within an Upper Zone, hosted within an upper claystone unit encountered by drilling from surface to about 425 ft (130m), and a Lower Zone, hosted within lower claystone and lower sandstone units intersected from 1,500-2,850ft (457-853m). Lithium mineralization appears to be hosted within non-swelling clay phases such as illite, or as lithium carbonate or salt within the sedimentary matrix. Boron mineralization appears to be associated with searlesite, a sodium borosilicate mineral.
While the Upper Zone and Lower Zones exhibit lithium and boron mineralization, they are separated spatially, and exhibit differences in metallurgical behaviour, leading the Company to treat them as two distinct deposits with different mining methods.
Lower Zone
While early exploration concentrated on mineralization in the Upper Zone, the Company has shifted its focus to mineralization in the Lower Zone, hosted in the lower claystone and sandstone units and containing the bulk of lithium and boron. This Lower Zone remains open to the NW, NE and SE. The current plan is to use an underground HBHM method, with a higher 1,800ppm cut-off. The Mineral Resource Estimate for the Lower Zone is presented in Table 1-1 and the sensitivity of the Lower Zone to cutoff grade is presented in Table 1-2.

Cautionary Statements Regarding Mineral Resource Estimates:
Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resources will be converted into mineral reserves. Inferred mineral resources are that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity. It is reasonably expected that the majority of inferred mineral resources could be upgraded to indicated mineral resources with continued exploration.
Resource Estimation Parameters
The updated Mineral Resource Estimate for Bonnie Claire was performed using Leapfrog® Geo and Leapfrog® Edge software. Leapfrog® Geo was used to update the geologic model, and Leapfrog® Edge was used for geostatistical analysis and grade modeling in the block model. An oblique view of the block model at Bonnie Claire is illustrated by Figure 1.1
Figure 1.1: Oblique view from southwest of block model for Bonnie Claire generated by Leapfrog® Edge software. Lithium ppm legend to right.
The drill hole database used for the estimation included:
- 21 exploration drill holes, including 8 reverse circulation holes and 11 vertical diamond core holes
- 9,159.54 meters of drilling in exploration drill holes
- 1,898 assay intervals in exploration drill holes
- Minimum grade of 18 ppm Li in exploration drill holes
- Maximum grade of 7,160 ppm Li in exploration drill holes
Cumulative probability plots of lithium and boron assay values did not exhibit grade breaks that would indicate the presence of outlier data, so the data were not capped or clipped. A specific gravity of 1.7 grams per cubic centimeter (g/cm3) for all lithological units, comparable to other similar lithium deposits. Drill hole assay values were composited to intervals of equal length to ensure that the samples used in statistical analysis and estimations were equally weighted. The majority of samples were collected at 6.096-meter (20-foot) intervals, with some samples collected at other intervals up to a maximum of 12.192 meters (40 feet). Down-the-hole composites were created from the Li and B assays within upper claystone, lower claystone, and lower sandstone mineralized domains, with the following specifications: 6.096-meter (20-foot) intervals, with anything less than 3.048 meters (10 feet) added to the previous interval. This resulted in 1,313 Li composite intervals with Li grades from 40.37 ppm to 5,764.48 ppm and 857 B composite intervals with B grades from 10 ppm to 14,658.8 ppm.
Qualified Person Terre Lane estimated Li and B grades into the block model using inverse distance to the second power (“ID2”) and for each method, a single pass was conducted at the ellipsoid ranges (1,600 meters x 900 meters x 150 meters). All blocks with modeled grade were coded as inferred resources. The search was restricted to a minimum of four samples and a maximum of 12 samples per block and a maximum of three samples per drill hole, thereby requiring data from a minimum of two drill holes to populate a block. For statistical comparison, nearest neighbor (“NN”) and ordinary kriging (“OK”) models were run to serve as comparisons with the estimated results from the ID2 method. The estimate means for the global population as well as the means for the estimation domains are similar, suggesting the ID2 estimate is not biased or overestimating the grades. The reduction in mean, coefficient of variation, and maximum from composites to the ID2 estimate shows an appropriate amount of smoothing. Swath plots and visual comparison of composites versus block model values by section and plan show good correlation.
Mining Methods
Hydraulic Borehole Mining of Lower Zone
As disclosed in their April 16, 2024, news release, Nevada Lithium contracted Kinley Exploration LLC (“Kinley”) to provide a preliminary evaluation of HBHM for Bonnie Claire.
Kinley was asked to establish a reasonable and economic mining strategy utilizing HBHM within the Bonnie Claire Lithium resource deposit to extract lithium in a continuous, efficient, cost effective and safe manner in the targeted higher grade zone from 1,500-2,800ft (457-853m) deep.
Kinley’s analysis took into consideration that the mineralization is highly plastic and with the assistance of jetting and pumping would likely flow. With this information, coupled with the significant cost of backfilling and then the consideration of subsidence, Kinley evaluated HBHM without backfilling and using directional drilling from a stable position.
The Kinley model assumed the highly mobile mineralization within the target section would behave plastically and flow in a fluid state or caving condition to the mining system intake. This relies on flow of the mobilized mineralization, accelerated by high pressure jetting to a centralized well, then pumped back to surface. GRE assumes a more conservative recovery of 60% because of potential mass flow issues that need to be evaluated during test mining.
Open Pit Mining of Upper Zone
Open pit mining of the Upper Zone at Bonnie Claire would likely use conventional mining equipment of hydraulic shovels and mining haul trucks but could possibly use scrapers. The soil is extremely soft and typically saturated. As a result, pit wall slopes would need to be relatively shallow; for the Lerchs-Grossman pit exercise in Section 14, the GRE Qualified Person used 18° side wall slopes. Additional geotechnical testing would need to be completed to determine stable side wall slope angles, bench heights, and catch bench widths. Dewatering portions of the pit, freezing, or other forms of stabilizing pit slopes and bottom may be required.
Mineral Processing and Metallurgical Testing
The mineral assemblage changes with depth. The Upper Zone generally shows lower grade lithium and boron and higher calcite content, while the Lower Zone tends to be significantly higher-grade lithium and boron and lower calcite content. The final mine design has not been completed, and the project may have several options: mine the upper portion, mine the lower portion, or mine the entire deposit. As a result, two distinct treatment options have been evaluated.
For the Upper Zone, a thermal treatment was developed that involved a sulfate calcination followed by a hot water leach. This process had the advantage of not solubilizing as many impurities, particularly iron. High lithium extractions (up to 80%) were achieved.
New drill samples from the Lower Zone were tested, and the calcination process was not effective due to the low melting point of the boron minerals (searlesite). Subsequently, sulfuric acid leaching was evaluated to treat the deeper deposit material. The acid treatment demonstrated that the lithium host is readily soluble in a strong sulfuric acid solution, achieving extractions of approximately 85%. The conventional downstream purification of the acid liquor had challenges for the upper sections of the deposit due to high iron solubilization.
Boron concentrations in the Lower Zone warrant a separate boron recovery circuit. Boron is recovered from the leach liquor after primary impurity removal via ion exchange to produce a boric acid product.
Quality Assurance / Quality Control
A quality assurance / quality control protocol following industry best practice was incorporated into the drill program by Nevada Lithium. Drilling was conducted by Major Drilling Group International Inc. (“Major Drilling”). Core was transported by Major Drilling from the collar location and received by Nevada Lithium staff at the Company storage facility in Beatty, Nevada. The facility is only accessible to Nevada Lithium staff and remains otherwise locked. Received core was logged and cut at the facility by Nevada Lithium staff. Logging and sampling included the systematic insertion of blanks, duplicates and certified reference material (“CRM”) MEG Li.10.12 and OREAS 750 into sample batches at an insertion rate of approximately 10%. All core samples collected were transported by Company staff to ALS USA Inc.’s laboratory in Reno, Nevada. for sample preparation. Sample preparation comprises initial weighing (Code WEI-21), crushing quality control test (CRU-QC), pulverizing quality control test (PUL-QC), fine crushing at 70% <2mm (CRU-31), sample split using Boyd rotary splitter ((SPL-22Y), pulverizing up to 250g 85% <75 µm (PUL-31), crush entire sample (CRU-21), pulp login (LOG-24) and a crusher wash (final crusher wash between samples (WSH-21). Samples were shipped to ALS USA Inc.’s Vancouver laboratory in Burnaby British Columbia, where the samples were analyzed using 48-element four-acid inductively coupled plasma mass spectrometry (ME-MS61) and B/Li N₂O₂ fusion inductively coupled plasma atomic emission spectroscopy high-grade (ME-ICP82b) procedures.
Data verification by GRE staff included: an on-site inspection of the Project site and core, reverse circulation and chip tray storage facilities, check sampling, geologic maps and reports, and manual auditing of the Project drill hole database. GRE’s Qualified Persons have been involved with the project since 2018. They visited the site in 2018 after drilling, during drilling in 2020 and 2022. The results from the site inspection, visual sample inspection and check sampling for each drilling campaign are given below. Based on the results of GRE’s Qualified Persons check of the sampling practices, verification of drill hole collars in the field, results of the check assay analysis, visual examination of selected core intervals, and the results of both manual and mechanical database audit efforts, GRE considers the collar, lithology, and assay data contained in the project database to be reasonably accurate and suitable for use in estimating mineral resources.
The data verification of the drilling campaigns shows that data from the rotary mud drilling was suspect and not used in the resource estimate. Open pit mining and processing methods, costs and infrastructure needs were verified by Ms. Lane in comparison to other similar sized open pit mines operating in the western USA. Borehole mining costs were developed by Kinley with coordination with GRE. Other cost data used in the report was sourced from the most recent infomine cost data report. All costs used to determine reasonable prospects for economic extraction were verified and reviewed by GRE and were assessed to be current and appropriate for use.
Metallurgical testing was completed for Bonnie Claire by a well-known commercial metallurgical laboratory. GRE reviewed all available metallurgical reports. GRE confirmed that the mineralization found at the Project is similar to another project where GRE has performed other consulting work and finds that the test work for Bonnie Claire shows that the material behaves in a similar manner, specifically in lithium extraction and recovery and reagent consumption. Given the similarities of the Bonnie Claire material to other similar projects, this provides a good basis for benchmarking the metallurgical test. The work appears to be professionally completed and is well documented and is suitable for estimation of lithium extraction and recovery calculations in the Mineral Resource Estimate.

Key Projects
Raleigh Lake
The Raleigh Lake project is ILC’s flagship asset, located approximately 25 kilometres west of Ignace, Ontario. The project covers a contiguous land package of 32,900 hectares and is 100 percent owned by the company. Raleigh Lake benefits from excellent infrastructure access, situated near the Trans-Canada Highway, a Canadian Pacific Railway line, and existing natural gas and hydroelectric infrastructure.
Major public infrastructure relative to the Raleigh Lake project
Raleigh Lake is notable for its dual potential to host both lithium and rubidium mineralization. The lithium is found primarily in spodumene-bearing pegmatites, while rubidium is associated with microcline-rich zones of the same lithium-cesium-tantalum pegmatite system. In 2023, International Lithium published a maiden mineral resource estimate (MRE) that delineated significant resources for both lithium and rubidium using separate cutoff criteria.
For lithium (Li₂O), the project hosts a measured and indicated resource of 5.88 Mt grading 0.79 percent Li₂O, and an inferred resource of 2.07 Mt grading 0.77 percent Li₂O, primarily within pegmatite #1. This lithium resource forms the basis of the company’s PEA, which demonstrated robust project economics with an after-tax NPV (8 percent) of C$342.9 million and an IRR of 44.3 percent.
The rubidium component, though not included in the PEA due to current market constraints, represents an additional potential value stream. The company has reported a measured and indicated resource of 133,000 tons at 6,163 ppm rubidium (0.67 percent Rb₂O) and an inferred resource of 123,000 tons at 4,224 ppm rubidium (0.46 percent Rb₂O), using a 4,000 ppm cutoff. The rubidium zones are found in association with potassic feldspar, offering a potentially recoverable byproduct pending further market and technical evaluation.
Given the project’s strong infrastructure position, mineral endowment, and defined development path, Raleigh Lake represents a compelling advanced-stage opportunity in North America's lithium supply chain. International Lithium is continuing infill and expansion drilling, environmental baseline studies, and metallurgical testing to support project advancement toward pre-feasibility.
Firesteel Project
The Firesteel project is an early-stage copper-cobalt exploration property located in northwestern Ontario, approximately 10 km west of Upsala along Highway 17. Spanning a 16-km corridor to the Firesteel River, the property lies within a geologically favorable region characterized by Archean metavolcanic and metasedimentary rocks, which are prospective for volcanogenic massive sulphide (VMS) and sedimentary copper systems.
International Lithium completed the acquisition of a 90 percent interest in the Firesteel project in May 2024, aiming to diversify its critical metals portfolio beyond lithium. Historical sampling on the property has returned encouraging results, including copper assays up to 2.6 percent and cobalt values reaching 309 ppm. Notably, the "Roadside 1" occurrence features semi-massive sulphide mineralization comprising pyrite, pyrrhotite, chalcopyrite and bornite. These findings suggest the presence of a highly metamorphosed VMS or sedimentary copper system, potentially up to 20 meters wide and extending over a kilometer in length.
The project's proximity to major infrastructure, including highways and railways, coupled with its strategic location near the company's Raleigh Lake project, enhances its development potential. International Lithium plans to conduct systematic exploration, including geochemical sampling and geophysical surveys, to refine targets for future drilling campaigns.
Wolf Ridge Project
Wolf Ridge is a 5,700-hectare grassroots lithium project located 20 km southwest of Upsala and near ILC’s Firesteel copper claims. The area benefits from excellent infrastructure, including proximity to Highway 17, power, and road access.
The project was highlighted by the Ontario Geological Survey (2021–2022) for its standout lake sediment anomalies - among the highest lithium values in the region - indicating strong potential for LCT pegmatite mineralization.

Southern Africa Exploration Initiative
Southern Africa is recognized as a prospective region for hard rock lithium, and International Lithium’s strategic focus reflects a proactive move to establish a presence in this emerging jurisdiction.
As part of its strategy to expand its critical metals footprint, International Lithium has applied for Exclusive Prospecting Orders (EPOs) over several prospective areas in Zimbabwe. The targeted regions are known for hosting spodumene, lepidolite and petalite-bearing pegmatites, indicating potential for significant lithium resources.
Although the EPO applications are still pending approval, the company has already conducted initial due diligence, including geological reviews and desktop studies, to prioritize exploration targets once access is granted. Zimbabwe’s growing importance as a global lithium supplier, combined with favorable mining policies, offers a compelling backdrop for the company's expansion efforts. International Lithium intends to leverage its technical expertise and exploration experience to quickly evaluate and develop these opportunities upon receiving the necessary permits

Metals Australia
Investor Insight
Metals Australia offers investors exposure to a rapidly advancing, high-grade graphite development project in Quebec with near-term growth catalysts, backed by strong government support, battery-grade test results, and a diversified portfolio of critical, precious and base minerals assets in tier-1 jurisdictions.
Overview
Metals Australia (ASX:MLS) is a mineral exploration company with a high-quality portfolio of advanced battery minerals and metals projects in tier-1 mining jurisdictions of Western Australia and Canada. The portfolio comprises two critical minerals projects in Quebec, Canada – the Lac Carheil flake graphite project and the Corvette River gold, silver and base metals project. The Australian portfolio comprises two projects: Warrego East (copper-gold) in Tennant Creek, Northern Territory, and Manindi (vanadium-titanium, zinc) in Western Australia.
The push for net zero targets and the call from policymakers to transition to cleaner energy has intensified the focus on electric vehicles (EVs) and battery storage. EV automakers and battery manufacturers rely on essential materials such as graphite and metals, including lithium, nickel, copper and cobalt, to manufacture the batteries that are used in these vehicles and storage batteries generally. This has driven carmakers and battery manufacturers to partner with battery material suppliers under direct off-take agreements. Further, some automakers/battery manufacturers are buying equity stakes in miners, involving them directly in financing decisions for the development of mining projects. This is encouraging for companies such as Metals Australia as it actively advances its projects towards development.
Graphite is a critical mineral required for the mass electrification of auto transportation.
Metals Australia is focused on progressing its flagship Lac Carheil flake graphite project in Quebec, Canada. The project is well-positioned to supply high quality graphite products, including battery-grade graphite, to the North American market – including for lithium-ion and EV battery production in the future. The company has completed a major winter drill program and is targeting a mineral resource upgrade in Q3 2025, with the updated resource to feed into the ongoing PFS and downstream studies.
Metallurgical work has demonstrated battery-grade spherical graphite (99.96 percent graphitic carbon) with high conversion efficiency and tap density. Downstream battery-grade purification and shaping test work is underway in Germany with ANZAPLAN.
Metals Australia is also advancing its gold silver and base metals exploration project at Corvette River, which is adjacent to Patriot Battery Metals’ world-class lithium project. Work to date has included mapping, trenching and sampling, with further drilling programs planned for 2025.
The company continues its exploration programs at its other Australian projects: Manindi (vanadium-titanium-magnetite) and Warrego East (copper-gold).
Company Highlights
- Metals Australia is rapidly advancing its flagship Lac Carheil graphite project in Quebec, Canada.
- The company holds a high-quality suite of exploration projects, including:

- All projects are located in tier-1 mining jurisdictions (Canada and Australia) with world-class prospectivity and stable geopolitics.
- The company’s four key projects include: Lac Carheil (graphite); Corvette River (gold, silver and base metals); Manindi (vanadium-titanium-iron + zinc-copper-silver) in WA; Warrego East in the NT (copper-gold)
- A 9,482 meters winter drilling program was completed at Lac Carheil in early 2025, increasing total drilling to ~11,800 meters.
- The program added more than 4,000 m of graphitic carbon drill intercepts to the 840 m used to define the initial mineral resource.
- Graphite mineralisation has now been confirmed to be over 2.3 km of strike length, up from 1 km, on just one of 10 mapped trends.
- A mineral resource estimate (MRE) update is expected in Q3 2025 to expand the existing JORC 2012 mineral resource of 13.3 Mt @ 11.5 percent Cg, and to support an expanded mine plan.
- Only 6 percent of 36 km mapped graphite trends have been drilled to date.
- Battery-grade graphite testing confirmed:
- 99.96 percent Cg purity
- 65.3 percent battery anode conversion efficiency
- 0.97 kg/L tap density
- A pre-feasibility study (PFS) is progressing with Lycopodium, and ANZAPLAN is advancing downstream test work for a battery anode material (BAM) facility.
- A C$600,000 grant awarded to Lac Carheil from the Quebec government to support pilot metallurgy and downstream studies.
- Exploration also continues across the Corvette River, Manindi, Warrego East Projects.
- Metals Australia is led by a seasoned board and management team with extensive mining experience and a strong track record of project development.
Key Projects
Canada
Lac Carheil Flake Graphite Project (MLS 100 percent)
The 100 percent owned Lac Carheil graphite project is located in eastern Quebec, a tier-1 mining jurisdiction with strong infrastructure and government support. The project lies near the town of Fermont and has excellent access to power and logistics, including proximity to the upgraded Highway 389, nearby hydropower infrastructure, and an expanding provincial road network.
Project location, claims boundaries, graphite resource & trends, regional magnetics & sample results
The current JORC 2012 mineral resource is 13.3 Mt 11.5 percent total graphitic carbon (Cg) for 1.53 Mt of contained graphite, based on limited drilling along just 1 km of a much larger 36 km mapped trend. The resource includes an indicated resource of 9.6 Mt @ 13.1 percent Cg, and inferred resource: 3.7 Mt @ 7.3 percent Cg.
A major 9,482-meter winter diamond drilling program was completed in early 2025, increasing total project drilling to ~11,800 meters. The program defined a new southeast extension zone with multiple intersections >15 percent Cg and demonstrated graphite continuity over 2.3 km of strike length, more than double the previous extent.
The results from this drilling campaign are being incorporated into an updated mineral resource estimate, expected in Q3 2025, which will underpin the next stage of project development.
Metallurgical and battery test work has confirmed Lac Carheil’s graphite is suitable for battery-grade applications, with:
- Flotation concentrate purity of 97 percent Cg
- Spherical graphite purity of 99.96 percent Cg
- Tap density of 0.97 kg/L
- Anode conversion efficiency of 65.3 percent, exceeding global industry averages
A PFS is being led by Lycopodium Minerals Canada and is progressing in parallel with downstream battery anode (BAM) test work led by ANZAPLAN in Germany, a location study for a BAM facility, likely in Canada, and marketing and pricing assessments in collaboration with Lone Star Technical Minerals.
The project is uniquely positioned to meet North America’s surging demand for secure, domestic graphite supply, especially for EV and energy storage battery markets. It represents a strategic, high-grade, long-life source of critical material, with potential for vertical integration from mine to battery anode material.
Corvette River Gold, Silver and Base Metals Project (MLS 100 percent)
MLS’s Corvette River Project Area’s – Felicie in the northeast, West and East Eade prospects to the south of the Corvette River, 2024 & prior sample result highlights, regional geology - including greenstone belts
The Corvette River gold, silver and base metals project is located in Quebec’s James Bay region. Corvette River comprises multiple prospects including East Eade, West Eade and Felicie. The 2024 program confirmed high-grade gold and base metal zones, with trench samples of up to 29.7 g/t gold. Field programs are ongoing, with follow-up work planned in 2025.
Australian Projects
Manindi Project (MLS 80 percent)
Located in the Murchison District of Western Australia, the Manindi project includes a JORC-compliant zinc-copper-silver resource of 1.08 Mt at 6.52 percent zinc, 0.26 percent copper and 3.19 g/t silver. The project also hosts a high-grade vanadium-titanium-iron (Ti-V-Fe) discovery zone situated adjacent to the base metals resource.
Recent metallurgical test work from the Ti-V-Fe zone has produced two commercially attractive concentrates: a high-grade iron-vanadium product grading 66 percent Fe and 1.19 percent V₂O₅, and a titanium-iron product grading 43.8 percent TiO₂ and 32.0 percent Fe. The combined mass recovery from the two products exceeded 65 percent of the sample, and both products displayed low impurity levels and strong commercial potential. Further processing optimization is underway to enhance the TiO₂ grade.
The mineralised Ti-V-Fe zone remains open at depth and along strike and is hosted within a 2 km-long magnetic gabbro trend. A program of work is being finalised to support drilling to define a mineral resource within the original discovery and to test four newly identified nearby targets. These complements renewed interest in the zinc-copper-silver resource due to stronger base metal prices.
Warrego East Project (MLS 80 percent)
The Warrego East copper-gold project is located in the Tennant Creek region of the Northern Territory, near the historically significant Warrego Mine. The exploration license (E32725) is fully granted, and the mining management plan has been approved. Land access agreements have also been finalised.
Geophysical surveys have defined 11 compelling magnetic and gravity targets along a known mineralised corridor. These targets lie within a prospective structural setting that hosts several high-grade historical deposits. A field program is being prepared for execution following the wet season, alongside three additional tenement applications that aim to expand the project footprint.
