A2Gold Completes Comprehensive Geophysics Program and Advances on Core Drilling at Eastside Project

Executive Summary

• A2Gold completed a two‑phase property‑wide geophysics program (gravity, airborne magnetic and radiometric surveys) at its Eastside Gold‑Silver Project, providing datasets that will guide target selection for an 18,000 m RC drill campaign slated later this year.
• The company is concurrently advancing a 2,000 m diamond core drilling program at the McIntosh zone, with Hole ES‑331 completed to ~530 m depth and results expected within 2–4 weeks.
• A2Gold entered into a four‑month marketing and investor‑relations services agreement with The Investing Authority (TIA) for a cash fee of US$150,000, subject to TSX Venture Exchange approval.

Key Details

• Geophysical Survey Completion
• Gravity survey: 800 stations on a 300 m grid covering the entire property, finished September 2025.
• Airborne magnetic & radiometric survey: 66.9 km² at 50 m line spacing (1,469 line‑km of data).
• Consultants: Chet Lide (planning) and James Wright of J.L. Wright Geophysics (interpretation/report).

• Results to be finalized in coming weeks and used to prioritize targets for the upcoming 18,000 m RC drill program.

• RC Drill Program

• Fully funded 18,000 m reverse‑circulation drilling scheduled to commence later in 2025 across multiple zones (McIntosh, Castle, etc.).

• Objective: test extensions of high‑grade intercepts and new structural targets identified by geophysics.

• Core Drill Program Update – McIntosh

• Hole ES‑331 completed, vertical depth ≈530 m, testing vertical extension of 2021 bonanza‑grade mineralization.
• Hole ES‑337 near completion, targeting multiple structural orientations and deeper gold zones.
• Hole ES‑338 planned at an angle to intersect feeder structures and seek additional high‑grade zones.

• First‑hole assay results anticipated within 2–4 weeks.

• Marketing Services Agreement (TIA)

• Parties: A2Gold Corp. and The Investing Authority (“TIA”).
• Term: Initial four‑month term beginning 1 Oct 2025, with a one‑month pause in Dec 2025; terminable for cause by either party.
