VANCOUVER, British Columbia, Aug. 05, 2026 (GLOBE NEWSWIRE) -- Asante Gold Corporation (TSXV: ASE | GSE: ASG | OTCQX: ASGOF ) ("Asante" or the "Company") is pleased to announce the filing of updated independently coordinated and prepared NI 43-101 technical reports for its Bibiani and Chirano Gold Mines in Ghana (effective 31 December 2025). These reports supersede the respective technical reports for Bibiani and Chirano filed on 30 April 2024 (effective 31 December 2023). Mineral Resources for both operations have been estimated using a gold price assumption of US$2,500/oz, and Mineral Reserves US$2,100/oz.

HIGHLIGHTS

Consolidated Resource Base

4.6 Moz Measured and Indicated (“M&I”) Mineral Resources across Bibiani and Chirano (inclusive of Mineral Reserves), in line with December 2023 level despite depletion and production over 430 koz in the aggregate two-year period.

1.8 Moz Inferred Mineral Resources across both operations, providing a strong near-term conversion pipeline with active drilling programmes targeting further additions through 2026.

Both Mineral Resource bases remain open at depth and along strike, with current definition extending to only approximately 300-700m below surface across the +80km Chirano-Bibiani Corridor (“CBC”).

The CBC comprises two principal, parallel Mineralized structures, the Bibiani Shear Zone (“BSZ”) and Chirano Shear Zone (“CSZ”), together defining one of West Africa's most prospective yet historically underexplored gold corridors.

Chirano Gold Mine

2.53 Moz M&I Mineral Resources (40.01 Mt at 1.96 g/t Au, inclusive of Mineral Reserves) and 830 koz Inferred Mineral Resources (13.8 Mt at 1.87 g/t Au).

Mineral Reserves of 1.30 Moz (23.69 Mt at 1.71 g/t Au) support a current seven-year Life of Mine plan.

More than replaced production depletion with an increase of 443 koz in M&I Mineral Resources and 244 koz in Mineral Reserves (rela
