Nevada Sunrise completes surveys at Griffon mine

Executive Summary

• Nevada Sunrise Metals Corp. completed its Fall 2025 surface exploration program at the Griffon Gold Mine Project in Nevada, utilizing AI-generated analysis from Vrify Technology Inc. to guide survey placement.
• The program included extensive geochemical sampling (over 700 soil samples via partial leach and soil gas hydrocarbon methods) and new geophysical surveys, including the first high-resolution magnetic data ("walking mag") and 3-D induced polarization/resistivity (3-D-IP) and audiomagnetotellurics (AMT) surveys.
• The company submitted a Plan of Operations to the US Forest Service in September 2025 for proposed surface disturbance and 2026 drilling plans and is currently awaiting comments regarding environmental baseline surveys.

Key Details

• Geochemical Surveys: Apex Geoscience USA collected over 700 soil samples for analysis using both ionic leach and soil gas hydrocarbon (SGH) methods to detect subtle indications of buried mineralization.
• Magnetic Surveys: Apex conducted a "walking mag" survey covering 50 line kilometres, providing the first high-resolution magnetic data at Griffon. Preliminary interpretation has clarified the structural settings of the Discovery Ridge and Hammer Ridge deposits.
• Geophysical Surveys: SJ Geophysics Ltd. performed 3-D-IP and AMT surveys covering 16.8 line kilometres on grids designed to investigate subsurface resistivity and chargeability characteristics; these survey types had never been performed at the property since gold discovery in 1986.
• Data Integration: The new geochemical and geophysical data will be integrated with Vrify's AI predictive model to develop drill targets for 2026.
• Resampling: Resampling and multielement geochemical analysis of reverse circulation drill cuttings from 2020 (originally assayed only for gold) is in progress. The broader package will include pathfinder elements such as antimony, arsenic, thallium, and mercury to enhance drill targeting.
• Permitting Status: A Plan of Operations was submitted to the US Forest Service (USFS) in late September 2025, with receipt confirmed in October 2025. The company awaits USFS comments on the timing and execution of required environmental baseline surveys prior to drilling.
• Historical Context: Griffon is a past-producing gold mine located in the Battle Mountain-Eureka gold belt. It produced 62,661 ounces of oxide gold from two open pits between 1998 and 1999 before premature closure.
• Project Assets: Griffon consists of 89 unpatented mineral claims totaling approximately 1,780 acres (720 hectares), located 50 km southwest of Ely, Nevada.

Notable Quotes

• "Nevada Sunrise is fortunate to have completed this important work during a period of favourable autumn weather in Nevada," said Warren Stanyer, president and chief executive officer 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."
