NEVADA SUNRISE ANNOUNCES FALL 2025 EXPLORATION PLANS FOR THE GRIFFON GOLD MINE PROJECT, NEVADA

Nevada Sunrise Metals Corp. is detailing its exploration plans for the fall of 2025 at the Griffon gold mine project in White Pine county, Nevada. Griffon hosts a past-producing gold mine and is located within the Battle Mountain-Eureka gold belt, a fertile trend that contains numerous gold mines and deposits.

Highlights of the fall 2025 exploration program

In the second quarter of 2025, Nevada Sunrise received positive results from AI-generated (artificial intelligence) analysis by VRIFY Technology Inc. of the extensive historical Griffon geological and geophysical database (see Nevada Sunrise's news release dated Sept. 9, 2025). The fall 2025 surface work will initially cover the unmined area south of the Hammer Ridge open pit (the Anvil zone) to help define a potential signature from a known gold occurrence and allow comparisons with the work carried out on the high-priority target areas defined by VRIFY. The 2025 fall exploration program includes:

• Comprehensive soil surveys incorporating leading-edge geochemical technology, for example soil gas hydrocarbon (SGH) and/or ionic leach methods, which can detect subtle indications of buried mineralization that may not show robust surface expression from conventional soil surveys;
• Ground geophysical surveys consisting of induced polarization/resistivity (IP/resistivity) and/or controlled source audio-frequency magnetotellurics (CSAMT) methods to better identify the character of the geological structures present at Griffon;
• Multielement geochemical analysis of reverse circulation drill cuttings collected at Griffon by Fremont Gold Corp. in 2020, which were historically assayed only for gold despite the presence of strong alteration in the deeper pilot shale member, for example hole GF20-07B. The broader analytical package includes antimony, arsenic, thallium, mercury and other important pathfinder elements that could provide geochemical vectors for new drill targets at the project.

"Our recent work at Griffon confirms the company's belief that since the early closure of the open-pit mining operation in 1999, sporadic exploration carried out over the last 26 years has only scratched the surface of the project," said Warren Stanyer, president and chief executive officer of Nevada Sunrise. "New discoveries of gold, both in near-surface deposits and at greater depths, are becoming more frequent in Nevada due to the growing geological knowledge base and the application of modern technologies, which Nevada Sunrise's exploration team is pleased to embrace."

Griffon permitting update

In late September, 2025, Nevada Sunrise submitted a plan of operations for Griffon to the United States Forest Service (USFS) to advise the USFS of the company's proposed surface disturbance and drilling plans at Griffon. The USGS has confirmed its receipt of the plan and the company awaits comments within a standard 30-day period from receipt. However, it is unknown at this time how the current U.S. government shutdown will affect the usual response time from the USFS.

About Griffon

Griffon is located approximately 50 kilometres (33 miles) southwest of Ely, Nev., and consists of 89 unpatented mineral claims totalling 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.

In February, 2025, the company entered into a mining lease to purchase Griffon from an arm's-length party (see Nevada Sunrise's news release dated Feb. 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 $278 (U.S.) per ounce (1).
