Nevada Sunrise Provides Lithium-Mineralized Clays for Super Critical Carbon Dioxide Extraction Testing, Gemini Lithium Project, Nevada

Nevada Sunrise Metals Corp. (‘Nevada Sunrise’, or the ‘Company’) (TSXV: NEV) (OTC: NVSGF) is pleased to announce that a novel form of metallurgical testing is underway on lithium mineralization from its 100%-owned Gemini Lithium Project (‘Gemini’) in Nevada utilizing super critical carbon dioxide as a leaching agent. A new patent granted by the U.S. Patent and Trademark Office in August 2023 to the Company’s consultant, Willem Duyvesteyn M.Sc. of Extractive Metallurgy Consultants LLC of Reno, Nevada (‘EMC’), is currently being tested on Gemini clay mineralization. EMC’s patented process could revolutionize the extraction of lithium from clay deposits by offering a ‘green’ processing method while at the same time providing in-ground sequestration of captured carbon dioxide (‘carbon capture’).

About Super Critical Carbon Dioxide

Super critical carbon dioxide (‘scCD’ or ‘sc CO 2 ‘) is used extensively in chemical industries, including, for example, for the production of decaffeinated coffee and various plant oils and extracts. Carbon dioxide (‘CO 2 ‘) reaches a supercritical state at 1,071 pounds per square inch (75.299 kg/cm 2 ) pressure and a temperature of 87.98° F (31.1° C), whereupon it attains the properties of both liquid and gas and can be utilized as a fast-acting solvent. Most importantly, scCD has been extensively investigated for the sequestration of CO 2 in various geological formations, including clay-type deposits.

It is commonly believed that lithium present in clay or ‘claystone’ deposits is held in the interlayer between the silica sheets of clays, such as smectite (hectorite), or illite (tainiolite) and is not very strongly bound. In the scCD extraction process proposed by EMC, CO 2 is converted to bicarbonate and this anion is readily picked up by the freed lithium ion, forming a water-soluble lithium bicarbonate. The resulting lithium bicarbonate compound is much more soluble than lithium carbonate. Some water in the interlayer will be displaced by CO 2 and therefore will provide opportunities to sequester CO 2 , thus providing an environmentally-friendly method of lithium extraction while establishing a unique form of carbon capture.

While the initial focus of the scCD testing is on the ex-situ , or off-site, processing of lithium-bearing clays, EMC has also identified the opportunity to use an in-situ approach employing freeze walls to contain the CO 2 in a section of a lithium-bearing clay deposit while implementing carbon capture of the CO 2 used during the lithium extraction process.

Results of the scCD testing of Gemini lithium-in-clay mineralization are expected in Q4 2023.

About Gemini

Gemini consists of 291 unpatented claims on Bureau of Land Management land covering approximately 5,600 acres (2,266 ha.) located in the western Lida Valley, Esmeralda County , approximately 6 miles (10 kilometres) east of the town of Lida, Nevada . The Lida Valley is a flat, arid basin with a similar geological setting to the better-known Clayton Valley basin where Albemarle Corporation operates the Silver Peak lithium brine mine, which has operated continuously since 1966.

Gemini is situated adjacent to the Gold Point Solar Energy Zone, a BLM land reserve set aside for solar and wind power generation projects until 2033. Exploration at Gemini is complemented by the Company’s 80.09 acre/feet/year water right, a pre-requisite for the exploration and development of lithium projects in Nevada .

In March and April 2022 , Nevada Sunrise drilled two RC boreholes for a total of 2,020 feet (615.85 metres) in its maiden drilling program at Gemini. The drill sites were located within a defined gravity low that hosts conductive layers detected by historical ground electromagnetic surveys. The results from the first two holes at Gemini represented a new discovery of lithium mineralization in the western Lida Valley, which was not historically drill tested for lithium (see Nevada Sunrise news release dated May 18, 2022 ). In July 2022 , Nevada Sunrise received a permit for an expanded drilling area from the Bureau of Land Management and began Phase 2 drilling at Gemini in October 2022. Three additional boreholes were completed from October 2022 to April 2023 , with each intersecting lithium mineralization (see Nevada Sunrise news release dated May 24, 2023 ).

Nevada Sunrise believes that the southern and western parts of the Gemini basin are highly prospective for additional lithium mineralization and that further drilling could eventually define a large lithium resource. The Company has engaged ABH Engineering Inc. of Surrey, BC , Canada to calculate a National Instrument 43-101-compliant resource estimate leading to a Preliminary Economic Assessment of the lithium-bearing zones at Gemini.

Initial metallurgical tests carried out by Nevada Sunrise achieved a 90.2% lithium extraction rate from the Gemini clay mineralization, a rate which compares favorably with the average lithium extraction of 84% reported by Lithium Americas at its Thacker Pass lithium project ( Source: Feasibility Study, National Instrument 43-101 Technical Report for the Thacker Pass Project, Humboldt County, Nevada , USA, by Roth, D., et al, dated November 2, 2022 ). Follow-up testing of the resulting leach solutions at the facilities of McClelland Laboratories Inc. in Sparks, Nevada produced a sample that was near-100% lithium carbonate (see Nevada Sunrise news release dated July 31, 2023 ).
