Abcourt launches drilling campaign at Barvue polymetallic site, Barraute sector, Abitibi-Témiscamingue

ROUYN-NORANDA, Quebec, June 01, 2026 (GLOBE NEWSWIRE) -- Abcourt Mines Inc. ("Abcourt" or the "Company") (TSX Venture: ABI) (OTCQB: ABMBF) is pleased to announce the launch of a new drilling campaign of approximately 2,000 metres at the site of the former Barvue silver and zinc mine, located in the Barraute sector of Abitibi-Témiscamingue. The work, which will begin during the first week of June, is directly aligned with the Company’s corporate strategy to enhance its premier silver assets following the recent dramatic increase in metal prices. Drilling Objectives: Targeting Unexplored Deeper Potential Past exploration work, as well as former open-pit and underground operations, never exceeded a vertical depth of 200 metres .

Volcanogenic Massive Sulphide (VMS) deposits in Quebec are buried at varying depths. While some deposits outcrop near the surface, they often extend deep underground. Geologically, we can compare the former Barvue mine to the Matagami zinc deposit; in this sense, the famous "Key Tuffite" is possibly the equivalent of the "Grey Tuff" found in descriptions of the geological units present at the Barvue mine.

Note that the main zinc-copper-silver mines of the Matagami camp, such as Isle-Dieu, Bell-Allard South, Bracemac-McLeod, Perseverance, and Norita, are found at depths ranging from the surface to more than 1,200 metres deep. The current campaign will consist of 4 drill holes of approximately 500 metres each. They will specifically aim to test silver-rich plunge extensions beneath the old pit, where mineralized axes of interest converge.

This is the very first time these high-value targets will be tested at this depth. A Rich History of Production Historical production at the Abcourt-Barvue mine (located near Barraute, Abitibi) totals more than 5.6 million tonnes of ore extracted during two distinct p
