Group Eleven Drills 15m of New Mineralization (incl. 2.8m of 8.3% Zn+Pb) in 550m Step-Out from Stonepark MRE, 20km NNW of Ballywire Discovery

Vancouver, British Columbia--(Newsfile Corp. - July 23, 2026) - Group Eleven Resources Corp. (TSXV: ZNG) (OTCQB: GRLVF) (FSE: 3GE) (" Group Eleven " or the " Company ") is pleased to announce a new and robust zone of mineralization has been discovered at its 78.62%-interest Stonepark Project in Ireland, adjacent to its 100%-interest PG West Project (" PG West "), hosting the Ballywire discovery. Highlights: 26-2638-07 - Drilled 550m from the closest edge of the Stonepark Mineral Resource Estimate 1  (" MRE "), intersected: 14.7m of 2.0% Zn+Pb (1.4% Zn and 0.6% Pb) (from 461m downhole), incl. 6.3m of 4.1% Zn+Pb (2.7% Zn and 1.3% Pb), incl. 2.8m of 8.3% Zn+Pb (5.5% Zn and 2.9% Pb), incl. 1.0m of 21.7% Zn+Pb (13.8% Zn and 7.9% Pb), 4 g/t Ag and 16.1m of 0.4% Zn (from 507m downhole), incl. 7.6m of 0.6% Zn, incl. 1.0m of 2.5% Zn+Pb (2.1% Zn and 0.4% Pb) Both zones are located within the lowest 65m of the Waulsortian Limestone and comprise of sphalerite, galena and pyrite Hole was drilled to 894m, testing for deeper Cu-Ag mineralization below the Waulsortian Limestone (assays pending) Intercept above is located 150m NW from the nearest historic hole (TC-2638-030; also outside of MRE), which intersected 3.2m of 4.4% Zn+Pb Two additional holes are planned as part of the remainder of current Stonepark drill campaign, totalling 2,700m At Ballywire, four rigs continue to be active, concentrated on the emerging SW extension of the discovery "Today's results represent the most significant progress at the Stonepark Project since we acquired the license block in 2017," stated Bart Jaworski, CEO. "Out of the seven step-out holes within the vicinity of the Stonepark MRE drilled by Group Eleven since acquisition, this is by far the most mineralized.
