Nevada Sunrise identifies gold anomalies at Griffon

Executive Summary

• Nevada Sunrise Metals Corp. has identified significant gold-in-soil anomalies at its Griffon Gold Mine Project in Nevada, specifically near the historic Discovery Ridge and Hammer Ridge pits.
• The 2025 Ionic Leach soil survey confirmed the detection capability of the method, with highly anomalous gold values found in the "Anvil zone," an area previously known to be mineralized by drilling but left unmined.
• The company is integrating this new geochemical data with historical databases and AI models to refine targets for a proposed 2026 drilling program, while awaiting USFS feedback on its plan of operations.

Key Details

• Survey Method: Multielement Ionic Leach soil sampling conducted in late 2025, collecting over 700 soil samples.
• Key Anomalies:
  • Gold-in-soil anomalies identified northeast and northwest of the Discovery Ridge pit and southeast of the Hammer Ridge pit.
  • The "Anvil zone" (contiguous to Hammer Ridge) showed strong gold values between 13.6 ppb and 59.6 ppb gold.
  • Pathfinder elements (arsenic, antimony, mercury, and thallium) were detected alongside gold, consistent with Carlin-type gold deposits.
• Historical Context: The Griffon project produced 62,661 ounces of shallow oxide gold from 1998–1999 before premature closure.
• Regulatory Status:
  • Plan of Operations submitted to the US Forest Service (USFS) in 2025.
  • USFS meeting held on March 26, 2026; USFS analysis is in process.
  • Company expects USFS comments in the second quarter of 2026.
• Data Integration: Results are being processed by Vrify Technology Inc. for integration with the DORA AI predictive model to enhance target generation for 2026 drilling.
• Technical Methodology:
  • Samples analyzed by ALS Global using proprietary Ionic Leach method.
  • Detection limits below parts per billion.
  • Leaching agent: Static sodium cyanide enhanced with chelating agents.
  • pH maintained at 8.5.
  • Analyzed via Inductively Coupled Plasma Mass Spectrometry (ICP-MS).

Notable Quotes

• "Our inaugural soil survey at Griffon reinforces the high potential for locating additional gold mineralization at the project... The use and integration of modern geochemical methods with our growing geophysical and geological database gives a higher degree of confidence to the development of targets for our proposed 2026 drilling program." — Warren Stanyer, President and CEO
