A2 Gold identifies drill targets at Eastside

Executive Summary

• A2 Gold Corp. has identified high-priority drill targets from a completed property-wide geophysical program (gravity, airborne magnetic, and radiometric) at its 100%-owned Eastside project in Nevada.
• The geophysical data redefines the project's potential, revealing a large, broad pediment corridor with thin cover and clear structural controls that extends beyond the known resource area.
• The company plans to commence an 18,000-metre Reverse Circulation (RC) drill program in January 2026 to test these new targets and conduct infill/stepout drilling at the McIntosh and Castle zones.

Key Details

• Geophysical Program: Completed gravity, airborne magnetic, and radiometric surveys covering the 92-square-kilometre A2 Gold claim block.
• Pediment Discovery: Geophysics indicate a 62-square-kilometre pediment shelf of alluvium-covered bedrock flanking the Monte Cristo Mountain Range. This area extends 16 km south from the McIntosh deposit to the historic Boss gold mine (Castle zone).
• Target Characteristics:
  • The pediment is interpreted to host gold deposits, with sparse historic drilling already discovering three gold deposits near Boss.
  • Alluvial cover thickness is estimated at 1 to 30 metres.
  • Several target areas (1 sq km and larger) of low-density volcanic rocks (rhyolite and tuffs) have been identified, similar to those hosting the McIntosh deposit.
• Alteration Anomalies: Airborne radiometric surveys show potassium, uranium, and thorium tracking hydrothermal alteration. One significant anomaly extends 5 km south from McIntosh, with permitted road building and drilling of 25-30 widely spaced holes.
• Structural Controls: Several structural boundaries (faults) trending north, northwest, and northeast were mapped, potentially controlling gold deposit position and grade.
• Drilling Plans:
  • Upcoming RC Program: 18,000 metres scheduled to commence in January 2026.
  • Previous DDH: A recently completed 1,680-metre diamond drill hole (DDH) program is awaiting assay results.
  • Objectives: Infill and stepout drilling at McIntosh and Castle to support an updated NI 43-101 resource estimate expected in Q1 2026; drilling of newly defined geophysical targets (pediment anomalies and structural corridors).
• Future Exploration: Follow-up geophysics, including CSAMT to map resistive silicified zones and Induced Polarization (IP) where sulfides are anticipated.
• Resource Context: The Eastside project currently hosts an inferred resource of 1.4 million ounces of gold and 8.8 million ounces of silver.

Notable Quotes

• Peter Gianulis, CEO: "The new data redefines Eastside. We now see a much larger potential mineralized system that continues well beyond the known resource area into a broad pediment corridor with thin cover and clear structural controls. The emerging targets provide a compelling road map for discovery-focused drilling that can meaningfully expand Eastside's scale and resource potential."
• Peter Gianulis, CEO: "We are in the final stages of selecting drill hole locations that will be the focus of our upcoming 18,000-metre RC drill program which is in addition to the recently completed 1,680-metre diamond drill hole (DDH) program. We expect to have assays from this DDH program in the very near future."
