NEVADA SUNRISE COMPLETES PHASE 2 DRILLING AT THE GEMINI LITHIUM PROJECT, NEVADA

Nevada Sunrise Metals Corp. has completed its phase 2 drilling program at its 100-per-cent-owned Gemini lithium project, located in the Lida Valley basin in Esmeralda county, Nevada. Three holes were completed in phase 2 for a total of 5,310 feet (1,618.9 metres), bringing the total number of holes drilled by the company at Gemini to five, totalling 7,330 feet (2,234.76 metres). The Gemini drilling program began in March, 2022, and was successful in intersecting lithium mineralization in every hole, both in sediments and in groundwater (see Nevada Sunrise news releases dated May 18, 2022, June 6, 2022, Feb. 7, 2023, and March 28, 2023).

Summary of borehole GEM23-05

GEM23-05, the final phase 2 borehole, was completed to a depth of 1,740 feet (530.49 metres) at a location approximately 0.52 mile (0.83 kilometre) south of borehole GEM22-02 and 1.04 miles (1.67 kilometres) southeast of borehole GEM23-04. After passing through Quaternary alluvium, the borehole intersected green clay from 440 feet to 540 feet (134.15 metres to 164.63 metres) followed by varying stratigraphies of green, brown and sandy clays and white ash tuffs until a rhyolite flow sequence was encountered at 1,575 feet (480.18 metres). The rhyolite sequence, predominantly dark grey to black volcanic glass (obsidian) flows with minor tuff and lithic tuff, may represent a basement layer unconformably overlying the much older Emigrant formation basement unit that was intersected in hole GEM23-03, drilled to 1,620 feet (493.9 metres), thus providing further definition of the depth of the Gemini basin.

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 is planning to carry out a phase 3 drilling program at Gemini later in 2023 to infill the current pattern of boreholes with the goal of producing a National Instrument 43-101 compliant resource estimate and a preliminary economic assessment of the lithium-bearing zones. In addition to the lithium-fertile western area of Gemini, the 2016 and 2022 geophysical results indicate continuity of the conductive zones in the eastern part of the project, where these untested zones appear to be mapping the lithium-bearing stratigraphies intersected in the phase 1 and phase 2 drilling.

A total of 49 groundwater samples and 172 sediment samples were collected from GEM23-05. Groundwater samples were collected intermittently at 20-foot intervals from a depth of 640 feet to a depth of 1,080 feet (195.12 to 329.27 metres), and then continuously from 1,120 feet to the bottom of the hole at 1,740 feet (341.46 to 530.49 metres). Sediment samples were collected at 20-foot (6.1-metre) intervals from the surface to a depth of 460 feet (140.24 metres) and then at 10-foot (3.05-metre) intervals from 460 feet (140.24 metres) to the bottom of the hole at 1,740 feet (530.49 metres).

Geochemical analyses for sediment and groundwater samples from GEM23-05 are pending and will be released following their receipt, compilation and interpretation.

About the 2022/2023 Gemini drilling program

In March and April, 2022, Nevada Sunrise drilled two RC (reverse circulation) 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-bearing sediments and lithium in water in the western Lida Valley, which was not 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 and GEM23-05.

In July, 2022, Nevada Sunrise received a permit for an expanded drilling area from the Bureau of Land Management (BLM) good until July, 2024.

About Gemini

Gemini consists of 582 unpatented placer and lode claims located in the western Lida Valley, Esmeralda county, approximately six miles (10 kilometres) east of the town of Lida, Nev. The Lida Valley is a flat, arid basin with a similar geological setting to the better-known Clayton Valley basin where Albemarle Corp. 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-foot-per-year water right, a prerequisite for the exploration and development of lithium brine projects in Nevada.

Sampling and analytical quality assurance/quality control and statement of qualified person

Sediment sample collection and analysis

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 three-to-five-kilogram sample for each sample interval. Samples were submitted to American Assay and ALS Global USA in Reno, Nev., and were analyzed utilizing a multielement 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 sample collection and analysis

Water parameters including TDS, conductivity, temperature and pH values were obtained in the field by direct measurement with a hand-held YSI556 multiparameter water meter, which meets good laboratory practice (as proscribed by the Organization for Economic Co-operation 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, Nev., under project chain-of-custody protocols for analysis. Industry-standard methods for examination of water are employed by the laboratory. General chemistry testing may include analysis for specific gravity, total hardness, total alkalinity, bicarbonate, carbonate, hydroxide, total dissolved solids (TDS) and electrical conductivity. Lithium is analyzed by inductively coupled plasma -- optical emission spectroscopy (ICP-OES) methods.
