Nevada Sunrise Metals Corporation Intersects 929.8 ppm Lithium over 1,130 Feet at the Gemini Lithium Project, Nevada
Nevada Sunrise Metals Corp. announced that the Company has received final geochemical analyses for lithium mineralization in sediments and groundwater collected from borehole GEM22-03, drilled at its 100%-owned Gemini Lithium Project ("Gemini") located in the Lida Valley basin in Esmeralda County, Nevada. Drilling of borehole GEM22-03 began on October 18, 2022 and was completed to a depth of 1,620 feet (493.90 metres) on December 16, 2022. Nevada Sunrise interprets the lithium-in-water results in GEM22-03 as groundwater flows that are situated higher up in the stratigraphy of the Gemini basin, and further north of the location of the stronger lithium-in-water results intersected in boreholes GEM22-01 and GEM22-02. Borehole GEM23-04 (in progress) has reached a depth of 1,900 feet as of February 2, 2023 and is an example of the Company's plan to drill deeper holes in the southern part of Gemini with the goal of: intersecting wide intervals of lithium-bearing sediments and locating higher concentrations of lithium-in-water coincident with significant groundwater flow rates. Nevada Sunrise drilled two reverse circulation ("RC") boreholes for a total of 2,020 feet (615.85 metres) in its maiden drilling program at Gemini in March and April 2022. 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 represent a new discovery of lithium-bearing sediments and lithium-in-water in the western Lida Valley, which has not been historically drill tested for lithium mineralization. Borehole GEM22-03, drilled to 1,620 feet (493.9 metres) intersected the same sequence of volcanic ash sediments as was found in GEM22-01 and GEM22-02, and similar geologic formations are observed in borehole GEM23-04, still in progress. In July 2022, Nevada Sunrise received a permit for an expanded drilling area from the Bureau of Land Management (the "BLM") and began Phase 2 drilling at Gemini in October 2022. Up to six boreholes are planned in Phase 2 for an estimated total of 8,000 feet (2,439 metres) of drilling. Gemini consists of 582 unpatented placer and lode claims 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 Bureau of Land Management 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 brine projects in Nevada. Under the laws of Nevada, water cannot be pumped from a subterranean source without a valid water permit. Sediment samples described in this new release are a composite of material collected from the rotary splitter in the RC drilling rig, which produces a continuous, representative 3 to 5 kilogram sample for each sample interval. Samples were submitted to American Assay and ALS Global USA in Reno, NV and were analyzed utilizing a multi-element ICP-AES method. Specifically, the analytical method involves aqua regia digestion of the sample followed by the inductively coupled plasma (ICP) technique to ionize the sample, and atomic emission spectrometry (AES) to determine elemental concentrations. Duplicates, field blanks, and certified reference standards were inserted at regular intervals in the sample stream to ensure accuracy of the analytical method. Water parameters including TDS, conductivity, temperature, and pH values were obtained in the field by direct measurement with a handheld YSI556 Multi-parameter water meter, which meets Good Laboratory Practice (as proscribed by the Organization for Economic Cooperation and Development) for calibration and measurement. Groundwater samples were collected at 20-foot (6.1-metre) intervals and sent to Western Environmental Testing Laboratory in Reno, Nevada under project chain-of-custody protocols for analysis. Industry standard methods for examination of water were employed by the laboratory. General chemistry testing included analysis for specific gravity, total hardness, total alkalinity, bicarbonate, carbonate, hydroxide, total dissolved solids (TDS) and electrical conductivity. Anions (chloride, sulfate) were analyzed by ion chromatography. Trace metals (lithium, magnesium, boron, calcium, potassium, strontium, and sodium) were analyzed by inductively coupled plasma-optical emission spectroscopy (ICP-OES) methods.
