Nevada Sunrise Intersects 1,321 ppm Lithium in Sediments over 990 feet and 116.43 mg/L Lithium in Groundwater over 140 feet at the Gemini Lithium Project, Nevada

VANCOUVER, Feb. 28, 2023 - Nevada Sunrise Metals Corp. ("Nevada Sunrise", or the "Company") (TSXV: NEV) (OTC: NVSGF) is pleased to announce that the Company has received initial geochemical analyses for lithium mineralization in sediment and groundwater samples collected from the first 1,500 feet (457.32 metres) of borehole GEM23-04, drilled at its 100%-owned Gemini Lithium Project ("Gemini") located in the Lida Valley basin in Esmeralda County, Nevada. Drilling of borehole GEM23-04 began on January 10, 2023 and was completed to a depth of 1,950 feet (594.51 metres) on February 22, 2023, which represents the deepest hole drilled to date at Gemini. The remaining samples collected in the final 450 feet (137.20 metres) of hole GEM23-04 are still in analytical process.

Highlights of GEM23-04

• Borehole GEM23-04 intersected 1,321.76 parts per million ("ppm") lithium-in-sediment over 990 feet (301.83 metres) from 510 feet (155.49 metres) to 1,500 feet (457.32 metres), including 3,556.82 ppm lithium over 110 feet (33.54 metres) and 4,329.60 ppm lithium over 30 feet (9.15 metres) (see Table 1 below);
• Water sample analyses showed anomalous concentrations of lithium in groundwater flows, notably an average of 116.43 milligrams/litre ("mg/L") lithium over 140 feet (42.69 metres), including intervals of 180 mg/L lithium from 1,200 to 1,220 feet (365.85 to 371.95 metres), 230 mg/L lithium from 1,260 to 1,280 feet (384.15 to 390.24 metres), and 200 mg/L lithium from 1,320 to 1,340 feet (402.44 to 408.54 metres). A second discrete interval higher up in the borehole returned 200 mg/L lithium over 20 feet (6.1 metres) from 1,100 to 1,120 feet (335.37 to 341.46 metres) (see Table 2 below);
• GEM23-04 was completed at a location approximately 0.70 miles (1.13 kilometres) southwest of GEM22-01 and 0.65 miles (1.04 kilometres) northwest of GEM22-02, thereby successfully extending the lithium mineralized zone at Gemini to the west.

Note: Sediment samples 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. All depth measurements reported, including sample and interval widths are down-hole. As holes at Gemini are oriented vertical and geologic stratigraphy is primarily horizontal to sub-horizontal, downhole measurements are assumed to be close to true thickness.

The Phase 2 drilling program at Gemini continues with borehole GEM23-05, currently underway, collared approximately 1.02 miles (1.64 kilometres) southeast of borehole GEM23-04, and 0.54 miles (0.87 kilometres) south of borehole GEM22-02.

To date, the Company has intersected significant intervals of lithium mineralization both in sediments and groundwater in all four holes completed since the inception of drilling. Nevada Sunrise believes that the southern and western parts of the Gemini basin could host higher concentrations of lithium and further drilling could eventually define a large lithium resource. The Company is enacting its exploration plan to drill deeper holes at Gemini with the goal of: (1) intersecting wide intervals of lithium-bearing sediments and (2) locating higher concentrations of lithium-in-water coincident with significant groundwater flow rates.

About the 2022-2023 Gemini Drilling Program

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 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 (see Nevada Sunrise news releases dated May 18, 2022 and June 6, 2022). 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, 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 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 brine projects in Nevada.

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 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 Sample Collection and Analysis

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.
