Abcourt Presents Operations Update for the Quarter ended March 31st, 2026, in the Development of the Sleeping Giant Mine

ROUYN-NORANDA, Quebec, April 15, 2026 (GLOBE NEWSWIRE) -- Abcourt Mines Inc. (“Abcourt” or the “Corporation”) (TSX Venture: ABI) (OTCQB: ABMBF)is pleased to provide an update on development work completed in the quarter ended March 31^st, 2026, at the Sleeping Giant Mine, located in the Eeyou Istchee region of Quebec.

In March, Abcourt continued hiring and training miners. Nine new employees joined the Abcourt team, bringing the total to 143 employees. The plan is to bring the total workforce to 190 employees in the coming months.

Operation Highlights

The gold inventory in the circuit on March 31 was 907 ounces.

The development of the drifts leading to the next long-hole stopes remains the Company 's priority. The first long-hole drill will be commissioned underground during the month of April and Abcourt anticipates the start of the first long-hole stopes in early summer 2026.

The work at the mining camp continued in March with the addition of a 37-room block, on top of the existing 50 rooms. This second phase in the mining camp construction was commissioned April 13^th. The construction of the third block of rooms in the mining camp is scheduled to begin in early summer.

Pascal Hamelin, President and CEO, stated: “With the long-hole drilling beginning in the coming weeks, we expect to increase our tonnage by an additional 1,500 tonnes per month average per long-hole stope. Ultimately, we plan to have three long-hole stopes in operation at the same time while developing the next stopes. Also, I wish to congratulate the construction team at the mining camp for the safe execution of the second phase. It shows very clear commitment to execute this type of construction on time and the middle of the Canadian winter.”

Gravimetric Geophysical Survey at Sleeping Giant

A gravimetric geophysical survey will soon be conducted across the entire Sleeping Giant property by the Val-d’Or-based firm Géophysique TMC. Approximately 750 measurement points will be used to cover the entire site.

The objective of this study is to identify the possible presence of significant mineralized zones at depth, which could correspond to massive sulfide deposits. This technology can detect anomalies up to approximately 2 kilometers below the surface, depending on conditions.

This survey is justified by recent observations of drill cores, which have revealed the presence of minerals such as sphalerite and chalcopyrite, often associated with gold. These observations suggest significant mineral potential linked to a deep volcanic source.

It is important to note that a survey of this scale has never been conducted on the property before, making it a first for Abcourt Mines. The results will allow for better targeting of future drilling and assessment of the deposit 's potential at depth, with the aim of optimizing the next stages of exploration.
