Asante Gold (ASE) Mining Forum Americas 2026 summary

Asset base and operating footprint

• Two operating mines, Chirano and Bibiani, span a contiguous 83 km corridor reunited within the past three years after more than 100 years apart.

• Asset base exceeds 6.5 million oz, with 2.8 million oz of reserves and a stated seven-year mine life; the land package is considered underexplored.

• Chirano has 3.6 Mtpa milling capacity, five underground mines and open pits; Bibiani has a large open pit and processing facility.

• Ghana is Africa’s largest gold producer, with gold accounting for 17% of GDP.

Chirano exploration and productivity

• A six-month exploration program in late 2025 added about three years of mine life in a recently released PEA; exploration continues underground and at surface.

• Drilling between Mamnao and Sariehu is identifying mineralization between the structures; drilling has yet to reach the higher-grade zones.

• Management aims to lift underground productivity, accelerate declines into higher-grade areas and improve equipment efficiency over the next 6–12 months.

• Kolua began mining in March 2026 with an initial three-month life and 10,000–15,000 t/month of oxide feed; follow-up drilling and grade control added another three months.

• Step-outs have extended the Kolua mineralized zone from 300 m to about 1,000 m; similar extensions are being pursued at shallow Mamnao.

Bibiani mine planning

• A January pit-wall failure covered much of the planned 2026 ore; waste removal was expected to finish around November 2026, while the ore delivery schedule was met.

• Oxide resources in Cuts 5 and 6, at about 1 g/t with better recovery through the Bibiani mill, could support surface mining and defer underground development.

• The revised concept would shift the production profile from 70%–80% toward about 30% underground, extend open-pit life and defer underground mining for several years.

• Two RC rigs began drilling gaps in Cut 5; deeper drilling has returned strong results and supports management’s view of orebody continuity.

• Russell Pit helped meet the 2026 ore schedule; future underground development may also access potential south of the pit.
