Bolo

A2 Gold owns 100% of the Bolo Project having recently acquired in August 2025 an additional 49.99% interest in the Project from CopAur Minerals Inc. thereby consolidating 100% ownership of Bolo.

Under the terms of the agreement, A2Gold will pay a cash consideration and forgive certain debt obligations owed to A2Gold by CopAur for historical advanced royalty and claim maintenance payments. In addition, the existing environmental reclamation bond for the Property will be transferred to A2Gold. Finally, CopAur will deliver a completed NI 43-101 technical report on the Property.

Bolo is an excellent exploration asset with a historical resource, in close proximity to several producing mines, and has the benefit of a recently completed NI 43-101 technical report. Consolidating ownership provides A2Gold maximum flexibility in unlocking the value of this highly prospective gold system located in one of Nevada’s best-known exploration belts.

The Property is located approximately 90 km northeast of Tonopah, Nevada, in a region known for hosting Carlin-type gold systems. Historic drilling has returned multiple zones of oxide gold mineralization at surface and at depth, and the Property benefits from road access, permitting, and numerous targets for further exploration.

The acquisition aligns with A2Gold’s strategy of prioritizing quality assets in mining-friendly jurisdictions with near-term exploration upside and potential for partnerships or future monetization.

Gold mineralization at Bolo is Carlin-type, similar to Pinson, Lone Tree/Stonehouse, and Turquoise Ridge/Getchell, all multi-million-ounce Nevada producers, where gold spreads into wall rocks along high-angle structures. Surface sampling at Bolo has defined widespread gold mineralization, associated with jasperoids and iron-stained structures, along two parallel north-south trending faults known as the Mine Fault and the East Fault. Alteration along the Mine Fault has been traced for 2,750 metres, with outcrop sampling returning gold values up to 8.6 g/t gold. The East Fault has been mapped for 2,200 metres and has returned gold values up to 4.7 g/t gold.

The Mine Fault and the East Fault and dozens of altered outcropping and buried cross-faults at Bolo have had very limited drilling and represent excellent exploration targets.

All of the gold mineralization intercepted at Bolo to date is logged as “oxidized” and is Carlin-type mineralization associated with weak silicification and decalcification of Paleozoic sedimentary rocks.

Exploration History

Bolo was drilled by Chevron, USMX, and Canerta in the 1970’s and 1980’s. However, most of the drilling was less than 45 metres in depth. Two shallow pods of oxide gold mineralization were encountered at the Mine Fault by previous operators and by Columbus Gold. Drilling by Canerta primarily concentrated along the southerly 300 metres of the Mine Fault, where several of the holes intercepted higher-grade gold mineralization, this area is now called the South Mine Fault Zone. Drilling at the South Mine Fault Zone by Columbus returned a number of favourable intercepts, including drill hole BL-38, which returned 133 metres of 1.28 g/t gold (including 30.5 meters of 3.24 g/t gold) from surface, drill hole BL-39, which returned 89.9 metres of 1.0 g/t gold (including 40.0 m. of 2.05 g/t gold) from surface, and hole BL-41, which returned 51.8 metres of 1.27 g/t gold from surface. Drilling by Chevron in 1975 encountered another pod of gold mineralization, located approximately 500 metres north of the South Mine Fault Zone, with hole HD-3 returning 18.1 metres of 1.51 g/t gold, from 7.5 to 25.6 metres.

The Uncle Sam patented claim, which is located immediately south of the South Mine Fault Zone, has yielded encouraging gold values, particularly from a small open pit, where continuous rock chip sampling by Columbus Gold along the pit walls has returned values up to 3.05 g/t gold and 1,074.1 g/t silver over more than a metre.

In addition to significant gold mineralization, Bolo has also returned significant silver values, hole BL-37 returned 3 metres of 360.5 g/t silver within 28.8 metres of 57.6 g/t silver.
