Mining Stock News: Spearmint (CSE: SPMT) (OTC Pink: SPMTF) Announces Maiden Resource Estimate on its Lithium Clay Project in Clayton Valley, Nevada

Vancouver, British Columbia – June 11, 2021 (Newsfile Corp.) ( Newswire) Spearmint Resources Inc. (CSE: SPMT) (OTC Pink: SPMTF) (FSE: A2AHL5) (FSE: SQH) (the “Company) is very pleased to announce that it has received the Technical Report and maiden resource estimate on its 100%-owned Clayton Valley Lithium Clay Project in Nevada, USA. The Technical Report includes a maiden resource estimate of 815,000 indicated tonnes and 191,000 inferred tonnes for a total of 1,006,000 tonnes of Lithium Carbonate Equivalent (LCE). The Technical Report was prepared in accordance with the requirements of National Instrument 43-101 by Stantec Consultant Ltd. (“Stantec”). Stantec’s qualified persons (Allan Turner, PGeol, and Derek Loveday, PGeo) have direct experience in the Tonopah area, which includes visiting Albemarle Corp.’s Silver Peak mine and ioneer Ltd.’s Rhyolite Ridge lithium-boron project and completing a resource estimate and technical report for American Lithium Corp. on the TLC lithium project.

Spearmint’s Project is located 55 kilometres west of the town of Tonopah. The Project is accessed off paved State Highway 265, which terminates at the Silver Peak Mine, and then by well-maintained county gravel roads. The Project consists of 26 contiguous unpatented placer claims that span from McGee 30 to McGee 55 and cover 890 acres (~360 hectares).

Drilling on the east half of the Project by Spearmint has discovered a continuous, well mineralized section up to 300 feet thick. The interpreted subsurface distribution of the mineralized claystone includes mixed sediments (tuffaceous mudstone) and green clay. The mixed sediments gradationally overly the green clays and are positively weathering relative to the green clay below. The majority (greater than 80%) of the mineralized claystone comprise the green clay unit.

The geologic model from which lithium resources are reported is a 3D block model. The resource estimates are contained within an economic pit-shell at a constant 45? pit slope to a maximum vertical depth of 535 ft (163 m) below surface, using a base case cut-off grade of 400 ppm lithium to produce an eventual battery grade lithium carbonate product.

The following costs, recoveries and revenue, in metric units and US$, were used to derive a base case cut-off grade for an eventual lithium carbonate (Li2CO3) product:

  • Mining costs US$2/tonne;
  • Processing costs US$15/tonne;
  • Processing recovery 80%; and
  • US$10,000/tonne revenue for Li2CO3 product.

The lithium mineral resource estimates are presented in Table 25.1 in U.S. customary units and Table 25.2 in metric units. Lithium resources are presented for a range of cutoff grades to a maximum of 800 ppm lithium. The base case lithium resource estimates are highlighted in bold type in Table 25.1 and Table 25.2. All lithium resources on the Project are surface mineable at a stripping ratio of 0.11 waste yd3/ton (0.09 m3/tonne) at the base case cut-off grade of 400 ppm lithium. The effective date of the lithium resource estimate is June 10, 2021.

James Nelson, President of Spearmint Resources stated, “We are very pleased to receive our maiden resources estimate that includes 815,000 indicated tonnes and 191,000 inferred tonnes for a total of 1,006,000 tonnes of Lithium Carbonate Equivalent (LCE) on our Clayton Valley Lithium Clay Project in Nevada. This is a monumental milestone for Spearmint as we now have our initial maiden resource for the Clayton Valley Lithium Clay Project. We have only drilled a minor number of holes to date to achieve this maiden resource, and we anticipate that additional targeted drilling could increase this initial calculation. We are already formulating a plan to achieve this goal. Spearmint’s recently completed drill program, that discovered lithium in all 10 out of 10 holes, was drilled directly into the shared blanket-like claystone deposit (see map) where our neighbour Cypress Development Corp. already has total measured plus indicated resource estimates of 929.6 million tonnes averaging 1,062 ppm Li or 5.2 million tonnes LCE, announced on August 11, 2020. Spearmint can now add its name to the list of companies with an in-ground resource estimate in Clayton Valley, Nevada. Clayton Valley continues to receive significant global attention as the premier lithium address in the USA, hosting the only producing lithium deposit in North America. Spearmint’s project is strategically located directly between Cypress Development Corp. and Pure Energy Ltd. Pure has a partnership with Schlumberger and are building a brine pilot plant with approximately $30 million USD being spent in developments. On the other side of Spearmint’s property, Cypress has recently closed a private placement for $19.55 million to develop their claystone deposit. This is a huge benefit to Spearmint to have two major adjacent projects being funded for over $50 million, allowing Spearmint the benefit of a significant outlay of research and development spending on either side of our property, without Spearmint having to commit our own money. Lithium prices remain high as we continue to see insatiable demand in batteries for Electric Vehicles without any sign of slowing down, therefore causing a massive demand for ethically sourced, domestic lithium production. Spearmint is currently in the best financial shape in the Company’s history with approximately $3.5 million in the treasury, including a recent investment by Sprott Asset Management LP as a new significant shareholder. Spearmint is now fully-funded for all upcoming planned work/drill programs on 3 other projects; our ‘Goose’ Gold Project in Newfoundland that is the closest property to the Keats discovery zone of New Found Gold Corp. whose share price recently crossed $13 per share; a drill program on our Perron-East Gold project in Quebec in direct proximity to AMEX Exploration Inc. and Starr Peak Mining Ltd.; and on our ‘Escape Lake North’ PGM Project in Ontario consisting of ~4,000 contiguous acres directly bordering Clean Air Metals Inc. We are moving forward at a rapid rate right now at a time when demand for lithium is approaching all-time highs and the price of gold is showing strength. Management remains confident about the short and long-term future of Spearmint.”
