Nevada Sunrise Completes Fall 2025 Surface Exploration at the Griffon Gold Mine Project, Nevada

Nevada Sunrise Metals Corporation (TSXV: NEV,OTC:NVSGF) (OTC Pink: NVSGF) (‘Nevada Sunrise’ or the ‘Company’) is pleased to announce it has completed surface geophysical and geochemical exploration surveys at its Griffon Gold Mine Project (‘Griffon’, or the ‘Project’) in White Pine County, Nevada, USA. 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.

Highlights of the Fall 2025 Exploration 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 September 9, 2025), including:

• Over 700 soil samples collected by APEX Geoscience USA (‘APEX’) will be analyzed by partial leach geochemical analysis by both Ionic Leach and Soil Gas Hydrocarbon (‘SGH’) methods. Each of these methods are capable of detecting subtle indications of buried mineralization that may not show robust surface expression from conventional soil surveys;

• APEX carried out a ‘walking mag’ survey consisting of 50-line kilometres that has provided the first ever high-resolution magnetic data at Griffon. Preliminary interpretation of the data has revealed important information about the structural settings of the past-producing Discovery Ridge and Hammer Ridge deposits – knowledge which now can be applied to other untested target areas at the Project;

• SJ Geophysics Ltd. carried out 3D induced polarization/resistivity (‘3D-IP’) and audiomagnetotellurics (‘AMT’) surveys consisting of 16.8 line kilometres on grids designed to investigate the resistivity and chargeability characteristics of the subsurface at Griffon. These survey types have never been performed at Griffon since the discovery of gold on the property in 1986 (see Figure 1).

‘Nevada Sunrise is fortunate to have completed this important work during a period of favourable autumn weather in Nevada,’ said Warren Stanyer, President and CEO of Nevada Sunrise. ‘The pending integration of new geochemical and geophysical data with VRIFY’s AI predictive model will be an invaluable addition to the development of Griffon drill targets for 2026.’

Nevada Sunrise anticipates the receipt of geochemical analyses and geophysical modeling from the ground surveys in January 2026. Re-sampling and multi-element geochemical analysis of reverse circulation drill cuttings collected at Griffon by Fremont Gold Ltd. (now Hayasa Metals Inc.) in 2020, which were historically assayed only for gold, is still in progress. The broader analytical package will include pathfinder elements such as antimony, arsenic, thallium, and mercury that could provide geochemical vectors to enhance drill targeting at the Project.

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. Receipt of the Plan was confirmed in October 2025 and the Company awaits comments from the USFS regarding the timing and recommended execution of environmental baseline surveys that are a requisite before the commencement of drilling.

About Griffon

Griffon 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.¹
