1.46 Million Ounces of Gold Outlined on Globex’s Duquesne West Property by Emperor Metals

Jul 9, 2025

July 9, 2025 – Rouyn-Noranda, Quebec, Canada. GLOBEX MINING ENTERPRISES INC. (GMX – Toronto Stock Exchange, G1MN – Frankfurt, Stuttgart, Berlin, Munich, Tradegate, Lang & Schwarz, LS Exchange, TTMzero, Düsseldorf and Quotrix Düsseldorf Stock Exchanges and GLBXF – OTCQX International in the US) is pleased to inform shareholders that Emperor Metals Inc. have published a new Mineral Resource Estimate on the Duquesne West Property in Duparquet Township, Quebec, a property 50% owned by Globex and under option by Emperor.

The new resource estimate is based upon a combination of open pit and underground mining methods. The new “Inferred Mineral Resource is 26.9 million tonnes containing 1.46 million ounces of gold at an average grade of 1.69 grams per metric tonne Au.” Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. Details of the parameters used in the resource calculation are available in the Emperor press release.

“The deposit features multiple high-grade zones within a broader low-grade, bulk-tonnage gold envelope with approximately 44% of the 1.46 Moz. amenable to conceptual open-pit extraction and 56% potentially minable via conceptual underground methods.” Globex is pleased by the progress to date and that Emperor have already more than doubled the historical resource. They have stated that “In 2025, the focus is on surpassing the Inferred two-million-ounce mark and driving continued resource growth through systematic exploration from 1000 feet depth to surface.”

Jack Stoch, President, CEO and Director of Globex commented “We are encouraged by the strong increase in resources that Emperor has estimated after their drilling programs on the Duquesne West. We look forward to seeing the continued progress on the Duquesne West project from the Emperor team.”

Strong potential exists for resource expansion including enhanced conceptual open-pit grade through additional discoveries of high-grade zones.
