Vancouver, British Columbia--(Newsfile Corp. - March 10, 2026) - Nevada Sunrise Metals Corporation (TSXV: NEV) (OTC Pink: NVSGF) ("Nevada Sunrise" or the "Company") is pleased to announce that it has received results from a comprehensive, multi-element geochemical resampling program of four (4) historical holes drilled at the Griffon Gold Mine Project ("Griffon", or the "Project") in White Pine County, Nevada, USA. The holes were drilled in 2020 by Fremont Gold Ltd. ("Fremont") but were analyzed only for gold. The results of the 2025 resampling correspond well with the gold analyses from mineralization intersected in the 2020 drilling and all four holes reveal the presence of classic pathfinder elements associated with Carlin-type gold deposits.

Highlights of the 2025 Geochemical Resampling Program

Nevada Sunrise based its Fall 2025 surface exploration program on the results of AI-generated analysis by VRIFY Technology Inc. ("VRIFY") of the extensive historical Griffon geological and geophysical database for the Project (see Nevada Sunrise news release dated December 18, 2025). The 2025 work included a resampling and reanalysis of historical reverse circulation drill cuttings from the 2020 drilling program carried out by Fremont.

• Nevada Sunrise obtained access to samples from four holes stored in a secure storage facility, and in December 2025 selected 205 residual pulps for 52-element reanalysis to provide superior geochemistry for sections of holes GF20-1, GF20-2, GF20-3 and GF20-7B, representing approximately 305 metres (1,000 feet) of drill cuttings;

• The Company's reanalysis corresponded well with Fremont's gold result from hole GF20-3, a vertical hole drilled to a depth of 165 metres (541 feet), which was collared within the unmined Anvil Zone on the southern edge of the Hammer Ridge pit (see Figure 1). In July 2020, Fremont reported gold values in near-surface oxide gold mineralization of 1.05 grams/tonne ("g/t") gold over 50.2 metres - the 2025 analysis by Nevada Sunrise returned 1.013 g/t gold over the same interval of 50.2 metres from 25.9 to 79.2 metres (85 to 260 feet), including 1.97 g/t gold over 10.7 metres from 64.0 to 74.7 metres (210 to 245 feet), and a peak value of 3.09 g/t gold over 1.5 metres from 68.6 to 70.1 metres (225 to 230 feet) (see Table 1).

• The Company's reanalysis of an 82.32 metre (270 foot) section of Fremont's hole GF20-2, a 45-degree angle hole drilled to a depth of 170 metres (558 feet) to the north of the Discovery Ridge Pit, duplicated the 2020 result with gold values of 0.30 g/t gold over 30.5 metres (100 feet), including 0.68 g/t gold over 7.7 metres from 21.3 to 29 metres (70 to 95 feet) and having a peak value of 0.954 g/t gold over 1.5 metres from 22.9 to 24.4 metres (75 to 80 feet).

• The pathfinder element geochemistry results in hole GF20-3 show a strong correlation between gold and anomalous values for arsenic, antimony, mercury, thallium and tellurium, all of which are known to be associated with the geochemical footprint of Carlin-type gold deposits and can provide a vector to gold mineralization.

• In sections of the two 2020 Fremont holes that showed strong alteration but no significant gold mineralization (holes GF20-1 and GF20-7B), highly anomalous values of pathfinder elements suggest that the holes were drilled within an alteration halo peripheral to a gold-mineralized zone. Values of pathfinder elements that are widely considered to be highly anomalous include: arsenic >98 ppm; mercury >1.2 ppm; antimony >20 ppm; and thallium >1.2 ppm.¹

"The results of our reanalysis not only confirm the gold results from the most recent exploration drilling at Griffon, but also provide valuable insight into the sub-surface distribution of pathfinder elements that can help lead us to locating new mineralization at the Project," said Warren Stanyer, President and CEO of Nevada Sunrise. "For the first time, these Carlin-type deposit pathfinder elements are clearly identified at Griffon and this information will be used as a vector for choosing new drill targets."

Griffon Permitting Update

In late September 2025, Nevada Sunrise submitted a Plan of Operations (the "Plan") for Griffon to the United States Forest Service (the "USFS") to advise the USFS of the Company's proposed surface disturbance and 2026 drilling plans at Griffon. The Plan proposes drill sites that are consistent with previously-permitted sites (see Figure 1), which were first approved by the USFS in 2013 after biological and archaeological studies were completed by previous operators. Correspondence from the USFS in February 2026 indicated that its comments are forthcoming regarding the drill targets proposed by the Company and Nevada Sunrise awaits their receipt.

About Griffon

Griffon hosts a past-producing gold mine and is located within the Battle Mountain-Eureka Gold Belt, a prolific trend that contains numerous gold mines and deposits. The Project is located approximately 50 kilometres (33 miles) southwest of Ely, Nevada and consists of 89 unpatented mineral claims totaling approximately 1,780 acres (720 hectares). Griffon is situated within a 60 kilometre (40 mile) section of the Battle Mountain-Eureka Belt, which hosts operating gold mines and significant gold deposits (see Figure 2).

In February 2025, the Company entered into a mining lease to purchase Griffon from an arm's-length party (see Nevada Sunrise news release dated February 20, 2025). Gold was mined at Griffon in two open pits from 1998 to 1999 and was reported to have produced 62,661 ounces of oxide gold until its premature closure in 1999, a year when the price of gold averaged approximately US$278 per ounce.³

Qualified Person

The scientific and technical information contained in this news release has been reviewed and approved by Robert Allender Jr, CPG, SME and a Qualified Person for Nevada Sunrise as defined in National Instrument 43-101 - Standards of Disclosure for Mineral Projects. Mr. Allender has examined information regarding the historical, current and proposed exploration at Griffon, which includes his review of the current and historical sampling, analytical procedures and results underlying the information and opinions contained herein.

Resampling of the 2020 drill cuttings was supervised by a senior geological consultant to the Company. Samples were submitted to American Assay Labs in Sparks, Nevada and analyzed by Four Acid digestion, which includes nitric acid (HNO₃), hydrofluoric acid (HF), hydrochloric acid (HCl), perchloric acid (HClO₄), boric acid solution (H₃BO₃) and deionized water. Digested samples are then subsequently run on ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) plus ICP-MS (Inductively Coupled Plasma Mass Spectrometry). Gold analyses were conducted by Fire Assay.

Management cautions that published historical results were collected and reported by operators unrelated to Nevada Sunrise and have not been verified nor confirmed by its Qualified Person; however, the historical results create a scientific basis for ongoing work at the Griffon property. Management further cautions that historical results, discoveries and published resource estimates on adjacent or nearby mineral properties, whether in stated current resource estimates or historical resource estimates, are not necessarily indicative of the results that may be achieved on the Griffon property.
