Lithium exploration and project developer Critical Resources Limited (ASX:CRR) (“Critical Resources” or “the Company”) is pleased to report further outstanding assay results from the Mavis Lake Lithium Project in Ontario, Canada.
Highlights
- Latest assay results from recent drilling at Mavis Lake have demonstrated continuity with previous, thick high-grade intercepts.
- The high-grade mineralisation within the Swell Zone starts from surface and extends over 1 kilometer in strike from east to west.
- Standout new assay results include:
- Drill-hole MF23-226 with a Swell Zone intercept of 31.55m @ 1.06% Li2O from 205.6m down-hole, and an additional ‘Lower Zone’ high-grade intercept of 20.7m @ 1.44% Li2O from at 339.3m down-hole.
- Multiple intercepts in drill-hole MF23-228, including:
- 16.8m @ 1.18% Li2O from 177.05m down-hole,
- 12.85m @ 1.39% Li2O from 208.1m down-hole, and
- 14.85m @ 1.25% Li2O from 333.25m down-hole.
- Multiple Project development workstreams continue including baseline environmental studies, metallurgical test work, mining studies and project economic analysis.
- Results pending from Main Zone drilling at Mavis Lake and drill-target generation field work at the Project’s northern prospects.
The latest assays have confirmed and extended the recently discovered Swell Zone and, when integrated with previous drilling results, show a thick, high-grade mineralised structure, starting from surface and extending over 1km in strike, sitting oblique to the current Mineral Resource Estimate (MRE).
1km Strike Length of Swell Zone
Recent drilling has established an important connection between previous drilling results, validating the Swell Zone discovery and demonstrating substantial Resource upside.
Current assays confirm a significant, 1km strike of high-grade mineralisation, starting at surface (refer to Figure 2) in the east and plunging gently to the west. Significant assays are shown in Table 1 and full exploration results are provided in Appendix 1.
The results confirm substantial thicknesses of high-grade lithium spodumene mineralisation. Importantly, when incorporating historical drilling the Company has now achieved tight drill spacing (approximately 50m spacing). The thickness and continuity of the Swell Zone, commencing from surface, is expected to contribute to positive future mining economics.
Much of the Swell Zone mineralisation sits outside the current Inferred MRE for Mavis Lake and presents as an immediate opportunity for immediate Resource growth.

Lower Zone Identified
Drill Holes MF23-226, MF23-227, MF23-228 and MF23-229 have all continued to intersect a “Lower Zone” of high-grade mineralisation, with a standout intercept of MF23-226 of 20.7 metres at 1.44% Li2O.
This Lower Zone was not identified in the Maiden Mineral Resource Estimate and presents as another immediate opportunity for Resource growth.
The Lower Zone can be seen in context relative to the Mavis Lake Main Zone intercepts in Figure 3.

Chariot Corporation
Investor Insights
Chariot Corporation presents a unique value proposition for seasoned investors, with its strategic ownership of the largest land package for lithium exploration in the US and a portfolio of non-core assets providing significant revenue opportunities.
Overview
Chariot Corporation (ASX:CC9) is the largest landholder for lithium exploration in the US. It has a strategy to target both hardrock lithium in Wyoming and claystone lithium in Nevada and Oregon. The flagship Black Mountain project in Wyoming has shown significant mineralization with grades of up to 6.68 percent Li2O from rock chip samples. Chariot’s six other hard rock projects in Wyoming span 443 claims covering 3,585 hectares.
The second flagship project, Resurgent, has the second largest land position in the McDermitt Caldera, which hosts the two largest lithium resources discovered to date (Thacker Pass with 44.5 million tons (Mt) lithium carbonate equivalent (LCE) and McDermitt at 21.5 Mt LCE). The recent $955-million investment in Thacker Pass by General Motors indicates interest from automakers looking to secure a supply of battery raw materials. The McDermitt Caldera’s size and scale potential present an opportunity for Automotive OEMs, battery manufacturers and others to obtain large-scale supply to meet their growth plans.
As the world's demand for lithium continues to grow, Chariot's exploration and development efforts in the US are well-timed and offer investors exposure to the rapidly growing lithium market.
The company believes its two core projects, Black Mountain and Resurgent, represent early, prospective lithium opportunities in the United States. Chariot has completed its phase 1 drill program at the Black Mountain project consisting of nine shallow holes, drilled from a total of 1,132 metres. Phase 2 drilling has commenced, which includes up to 18 drill holes targeting a high-grade spodumene resource to support the establishment of a pilot mine.
Chariot Corporation announced a revised strategy for the Black Mountain hard rock lithium project to establish a small-scale “pilot mine”. Chariot aims to supply spodumene concentrate to several lithium hydroxide refineries under construction in the southwestern United States. Strategically located in Wyoming, Chariot can leverage Wyoming’s small-mine permit system to provide short-term cash flow and potentially optimize the development of larger-scale mining operations in the future.
Chariot boasts a world-class team with strong track records in mining, exploration and the financial services sectors. The management has significant corporate and investment banking experience. CEO, Shanthar Pathmanathan was an oil and investment banker with Macquarie and Deutsche Bank. On the geological side, Neil Stuart who is a non-executive director is a lithium industry veteran having previously founded Orocobre Ltd (which merged with Galaxy Resources and later with Livent) to form Arcadium Lithium, one of the largest lithium producers in the world which has recently been acquired by Rio Tinto. The exploration team is led by Dr. Edward Max Baker, a geologist with over 40 years of experience and several discoveries. He was the chief geologist at Newcrest Mining, MIM Holdings, Rennison Goldfields and Mount Isa Mines. The collective experience of the management team, from investment banking (with fundraising and M&A experience) to resource discoveries, will be useful in advancing the company’s core projects.
Company Highlights
- Chariot Corporation is a mineral exploration company focused on discovering and developing high-grade and near-surface lithium opportunities in the US.
- Chariot holds the largest land position for lithium exploration in the US with hard rock lithium and claystone hosted lithium exploration assets.
- The company commenced trading on the ASX in October 2023 after closing a highly sought-after and oversubscribed AU$9 million initial public offering (which is in addition to AU$14.8 million being raised privately to assemble the portfolio).
- It is currently focused on its two core projects in the US: (1) the Black Mountain project, a hard rock lithium project located in Wyoming; and (2) the Resurgent project, a claystone lithium project located in Oregon and Nevada.
- Chariot also holds an exploration pipeline of six projects in Wyoming including Copper Mountain, South Pass, Tin Cup, Barlow Gap, Pathfinder and JC projects. These projects are prospective for hard rock lithium.
- Through the company’s interest in Mustang Lithium, Chariot also has exposure to two claystone projects where substantial initial drilling has been completed - Horizon Lithium and Halo Lithium. Horizon Lithium has a lithium resource estimate of 1.3 million tonnes indicated LCE and 8.8 million tonnes LCE inferred.
- Chariot recently announced a revised strategy for the Black Mountain hard rock lithium project to develop a small-scale “pilot mine” to supply spodumene concentrate to several lithium hydroxide refineries under construction in the southwestern United States.
- Chariot also holds interests in several projects that have been either sold or conditionally divested through option agreements to publicly listed companies. A publicly listed counterparty operates each of the divested projects and depending upon the particular transaction, the projects generate additional revenue for Chariot in the form of future payments and royalties.
- Chariot offers investors exposure to the nascent and rapidly growing US lithium market.
Key Projects
Black Mountain Project, Wyoming
The Black Mountain project is Chariot’s flagship hard rock lithium project located in Natrona County, approximately midway between Casper and Riverton, Wyoming. Chariot initially held a 91.9 percent stake in the project with 134 mining claims covering 878 hectares. In 2024, the company expanded the project with 218 contiguous claims resulting in a 206 percent increase in project tenure area. Black Mountain now comprises 352 claims covering 2,686 hectares of tenure which subsequently increased Chariot's ownership interests in its Wyoming lithium portfolio to 93.9 percent.
The project is well-serviced by existing roads and infrastructure. The claim area was acquired via claim staking of public land administered by the US Bureau of Land Management.
The project features large pegmatite outcrops at the surface with spodumene and tantalum mineralisation. Surface rock chip samples returned assays of up to 6.38 percent lithium oxide.
Black Mountain may represent a significant hard rock lithium opportunity in a tier-1 mining jurisdiction in the US. The asset features an excellent combination of geological factors, and a supportive regulatory regime and is located in a largely unpopulated part of Wyoming.
In connection to the company’s shift to establishing a pilot mine, the following factors relating to the Black Mountain Project render it particularly suitable for this goal:
- Indications of near-surface lithium mineralization at Black Mountain make it suitable for a shallow, open-pit pilot mine.
- Wyoming’s advantageous small-mine permit system offers a pathway for small mine permits that does not impose limits on the mineral volume which can be extracted but rather places annual limits on the mining activities to 10 acres (4.05 hectares) of disturbance and 35,000 cubic yards (26,760 cubic metres) of overburden removal (refer Part 3 of this announcement).
- Black Mountain’s proximity to US lithium hydroxide refineries currently under construction in the southwestern United States is expected to provide a geographic advantage in marketing product extracted from the mine.
Resurgent Project, Nevada and Oregon
The Resurgent project is a claystone-hosted lithium project located in the McDermitt Caldera in Oregon and Nevada. The company owns a 79.4 percent stake in this project. The Resurgent project comprises 1,450 claims covering 12,128 hectares and is further subdivided into two principal claim areas, identified as ‘Resurgent North’ and ‘Resurgent East.’ Chariot has the second-largest land position in the McDermitt Caldera, which hosts two of the largest lithium mineral resources in North America, with a combined mineral resource estimate of over 40 Mt LCE - Thacker Pass at 19.1 Mt LCE and McDermitt at 21.5 Mt LCE.
The Resurgent North project targets the same sedimentary units that host Jindalee Resources' (ASX:JRL) McDermitt project with a mineral resource estimate of 21.5 Mt LCE. A surface sampling campaign at Resurgent North conducted in 2021 involving 289 samples returned values as high as 3,865 ppm lithium (over three times typical lithium claystone MRE cut-off grade). Of the 289 samples, 70 samples returned values greater than 100 ppm lithium, 20 samples returned values greater than 1,000 ppm lithium and 10 samples returned values greater than 2,000 ppm lithium.
The Resurgent East project targets the same sedimentary units that host Lithium Americas’ (NYSE:LAC) Thacker Pass lithium deposit (MRE at 19.1 Mt LCE). The similarity in geological characteristics with the two largest lithium deposits in the US further validates the potential for a large-scale high-grade lithium discovery at Resurgent.
Exploration Pipeline Projects
Besides the two core projects, the company has a pipeline of six lithium exploration projects comprising 443 claims and covering 3,585 hectares. Each of them is described below:
- Copper Mountain Project: The project is located ~80 kilometres northwest of Black Mountain in Fremont County, Wyoming. It comprises 83 mining claims covering 648 hectares. Copper Mountain has a long history of prospecting and artisanal-scale production having been historically mined for mica, feldspar, beryl, lepidolite and tantalite. The company has already identified multiple pegmatite target areas and has plans for a geochemical and ground magnetics survey in addition to geological mapping.
- South Pass Project: The project is located in Fremont County, Wyoming, and comprises 214 mining claims covering 1,750 hectares. This is a large and highly prospective project with an abundance of outcropping pegmatites that occur in swarms. The company notes the individual pegmatites at the project could range up to several hundred metres wide and several thousand metres long. There has been no prior exploration for hard rock lithium in the South Pass project area.
- Regional Wyoming Exploration Pipeline Projects: It comprises four hard rock lithium mining projects namely Tin Cup, Pathfinder, Barlow Gap and JC, comprising 146 mining claims covering 1,146 hectares.
- Barlow Gap Project: This project is located in Natrona County, Wyoming, and comprises 60 mining claims covering 501 hectares. This is an early-stage hard rock lithium exploration project with outcropping pegmatites on a northeast trend.
- Tin Cup Project: The project is located in Fremont County, Wyoming, and comprises 45 mining claims covering 376 hectares. There is a long history of exploration at The Tin Cup mining district dating back to 1907. The region has been known for small-scale mining for gold, copper and various gemstones including red jasper, ruby and jade. This is an early-stage hard rock lithium exploration project with outcropping pegmatites.
- Pathfinder Project: This is an early-stage hard rock lithium project located in Natrona County, and comprises 32 mining claims covering 234 hectares.
- JC Project: Located in Fremont County, Wyoming, the project comprises nine mining claim blocks spanning 75 hectares. This is an early-stage hard rock lithium exploration project that features several small excavation pits and outcropping pegmatite dykes.
Divestment Projects
Chariot has been actively focused on creating value via divestment of selected lithium assets in its portfolio, which include the following assets: Lithic & Mustang (ownership 21.4 percent) and the WA Lithium portfolio (Chariot was the 100 percent owner of this property prior to the sale to St George Mining Ltd). In addition, Chariot through its interest in Mustang Lithium has exposure to the Horizon and Halo claystone lithium projects in Nevada, USA. Both projects have completed drilling campaigns and Horizon announced a resource of 1.3 million tonnes LCE and 8.8 million tonnes LCE inferred. These divestments and interests have the potential to generate more gross proceeds (cash and stock-based consideration) for Chariot in addition to future royalty payments.
The company has identified four more projects for divestment: Lida project (Nevada), Amargosa project (Nevada), Nyamukono project (Zimbabwe), and Mardabilla project (Western Australia).
