Abcourt starts the mill at the Sleeping Giant Project

Abcourt Mines Inc. (" Abcourt " or the " Corporation ") (TSX Venture: ABI) (OTCQB: ABMBF) is pleased announce that it has started the mill at the Sleeping Giant Project in Eeyou Istchee, Québec.

Following the recent update made in the August 7 ^th press release, the Corporation is happy to announce that the mill is currently turning at the Sleeping Giant site. The material processed comes 100% from the development operations at the Sleeping Giant project directly under the mill. The Corporation will fill the mill circuit within the next few weeks to pour the first gold bar from Sleeping Giant since 2014.

Historically, from 1987 to 2014, this mill processed 3.37M tons mined from the Sleeping Giant deposit at 10.29 g/t Au to produce 1,073,111 oz Au. It later processed the material from the Elder mine from 2016 to 2022. More recently, in 2024, it completed the processing of the 5,000 tons bulk sample from the Pershing-Manitou deposit at a rate of 32 tons per hours. In the last few months, Abcourt invested funds to put the mill in operational state.

Pascal Hamelin, President and CEO of Abcourt, commented: "We are very pleased with the way operations are going so far. Having the mill out of its care and maintenance mode is a major milestone that shows the market our constant advancement. We've operated this mill in the past, and we believe the ramp up and testing phase on the current material should be smooth and without major issues. Then, the company plans on meeting with the investment community through different trade shows until the end of 2025 to showcase our great project."

The company will be attending the Mining Forum Americas 2025, from September 14 to 17, 2025, at the Broadmoor Hotel & Resort in Colorado Springs, USA, to present its achievement to the mining investment world.
