Nevada Sunrise Metals Corp. (TSXV: NEV) (OTC: NVSGF) announced the reception of final geochemical analysis for lithium mineralization in sediment and groundwater samples from its Gemini Lithium Project in Nevada on Wednesday.
The Gemini Lithium Project is located in the Lida Valley basin in Esmeralda County, and the company drilled borehole 23-04 to a depth of 1,950 feet, representing the deepest hole drilled to date at Gemini.
Borehole GEM23-04 intersected significant concentrations of lithium in sediment, including 1,412.38 parts per million (PPM) over a 1,440-foot section. This includes two notable sub-sections with higher concentrations of 3,556.82 ppm over 110 feet and 4,329.60 ppm over 30 feet.
Additional analyses of water samples from the area also revealed high concentrations of lithium, including a 20-foot interval with 490 milligrams per litre lithium content.
Borehole23-04 was drilled about 0.73 miles southwest of GEM22-01 and 0.65 miles northwest of GEM22-02. Consequently, this expanded the lithium mineralized zone to the west.
The phase 2 drilling program at Gemini is ongoing, with the current focus on borehole GEM23-05. As of March 27, 2023, this borehole has reached a depth of approximately 1,510 feet and is situated about 1.04 miles southeast of GEM23-04 and 0.52 miles south of GEM22-02. With the information gathered from this drilling program, the project team hopes to gain a better understanding of the lithium deposit and further expand the mineralized zone.
Nevada Sunrise has intersected significant intervals of lithium mineralization both in sediments and groundwater in all four holes since it started drilling. It also continues to intersect the clay layers and groundwater flows that could theoretically host additional lithium mineralization.

South and west parts of the basin are serious mineralization prospects
The company believes that both the southern and western parts of the basin are serious prospects for lithium mineralization. Nevada Sunrise also recognizes that further exploratory drilling could define a large resource.
The objective of the exploration plan is twofold to intersect wide intervals of lithium-bearing sediments and to locate higher concentrations of lithium-in-water coinciding with significant groundwater flow rates.
Nevada Sunrise drilled two boreholes in March and April 2022 for 2,020 feet in its maiden drilling program at Gemini. The company located the drill sites in a defined gravity low hosting conductive layers detected by historical ground electromagnetic surveys.
The results from the first two holes at Gemini included a new discovery of lithium-bearing sentiments and lithium-in-water in the western Lida Valley. Additionally, the valley hadn’t been historically tested for lithium mineralization prior to this discovery.
The company received an expanding drilling area permit from the Bureau of Land Management, which is good until July 2024. It started drilling its phase 2 at Gemini in October.
Since then borehole GEM22-03, drilled to a depth of 1,620 feet, found the same volcanic ash sediment sequence observed in GEM22-01 and GEM22-02, which is consistent with the geological formations in the ongoing GEM23-04 and GEM23-05 boreholes.
