Abcourt obtains its environmental certificate of authorization for custom milling

at the Sleeping Giant Mill

Rouyn-Noranda, Canada, October 28 , 2025 - Abcourt Mines Inc. (“Abcourt” or the

“Corporation”) (TSX Venture: ABI) (OTCQB : ABMBF) is pleased to announce the receipt of

its environmental certificate of authorization for custom milling of ore from off -site deposits at its

Sleeping Giant mill.

This certificate of authorization allows Abcourt to begin commercial discussions with potential

clients, accelerate the environmental authorization process, and begin processing gold ore from

mining companies that do not have a mill to extract gold from their ore. Building an ore processing

complex to extract gold and store the pulp is a process that can takes several years and can costs

several hundred million dollars. For many gold development companies, negotiating custom

milling may be a faster and more cost-effective option.

According to our Preliminary Economic Assessment (PEA) for the Sleeping Giant Mine published

June 7, 2023, the Sleeping Giant Mill will use less than 4 0% of its capacity to process ore from

the Sleeping Giant Mine. The mill permitted daily throughput is 950 tonnes per day , and the

average planned throughput is 340 tonnes per day in the PEA. In the long term, Abcourt's

objective is to define additional mineral resources at the Sleeping Giant Mine to maximize the use

of its mill with ore from internal sources. In the short term, Abcourt will have the opportunity to

process ore from other sites and thus benefit from additional revenue sources in addition to

executing its business plan with production from Sleeping Giant.

Pascal Hamelin, President and CEO, states: " The Abitibi and Eeyou Istchee regions are rich in

gold deposits that are too small to justify the initial investment of building a gold processing

complex. Abcourt now offers an attractive alternative to accelerate the development of these

deposits. In addition, this type of custom milling allows us to maximize the use of our mill, increase

our revenue and the value of our asset , and finally allow us to evaluate the potential synergies

with other deposits around us."
