NEVADA SUNRISE COMMENCES FALL 2025 EXPLORATION AT THE GRIFFON GOLD MINE PROJECT, NEVADA

Nevada Sunrise Metals Corp. has commenced at the Griffon gold mine project in White Pine county, Nevada, United States. 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

APEX Geoscience (USA) Ltd. of Reno, Nev., has been engaged to carry out the first components of the fall 2025 exploration program, which will focus on the high-priority target areas defined by AI predictive modelling by Vrify Technology Inc. (Vrify, see Nevada Sunrise news release dated Sept. 9, 2025), including the unmined area south of the Hammer Ridge open pit (the Anvil zone) to help define a potential signature from a known gold occurrence. Work in progress includes:

• A comprehensive soil survey program of up to 700 samples incorporating leading-edge geochemical technology, that is, ionic leach and soil gas hydrocarbon (SGH) methods;
• A walking mag ground geophysical survey to improve the geophysical database for the project. This high-resolution 2025 ground magnetics survey represents the first survey of its type at Griffon.

"Our momentum is building at Griffon within a Nevada gold trend that is one of the most prospective areas to explore for gold in the United States," said Warren Stanyer, president and chief executive officer of Nevada Sunrise. "The existing deposits and mines in the Battle Mountain-Eureka gold belt are attracting attention worldwide because of the quality of the projects, the state of Nevada's positive reputation in the mining business and a recent groundswell of American government support for mineral projects in the USA."

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 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.

Additional 2025 planned exploration

The following fall 2025 exploration activities are planned or in progress:

• Induced polarization/resistivity (IP) and controlled source audio-frequency magnetotellurics (CSAMT) ground geophysical surveys 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 Ltd. in 2020, which were historically assayed only for gold. 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.
