Group Eleven drills 23.5 m of 12.3% Zn+Pb, 46 g/t Ag; extends 3.2 km strike

Vancouver, British Columbia--(Newsfile Corp. - April 16, 2026) - Group Eleven Resources Corp. (TSXV: ZNG) (OTCQB: GRLVF) (FSE: 3GE) (" Group Eleven " or the " Company ") is pleased to announce new assay results from its Ballywire discovery (" Ballywire ") at the 100%-owned PG West Project (" PG West "), Republic of Ireland. Highlights: 25-3552-53  – Extends previous interval from 25-3552-51 announced on 19-Jan-2026, totalling 29.9m of 15.3% Zn+Pb, 552 g/t Ag and 0.67% Cu (from 338m downhole, at base of Waulsortian Limestone), downdip and to the SE along two zones: Waulsortian Limestone hosted (40m extension from 25-3552-51) 57.3m of 6.2% Zn+Pb (3.4% Zn and 2.8% Pb), 35 g/t Ag (from 322m downhole), incl. 23.5m of 12.3% Zn+Pb (6.2% Zn and 6.1% Pb), 46 g/t Ag , incl. 11.3m of 17.6% Zn+Pb (8.2% Zn and 9.4% Pb), 60 g/t Ag , incl. 4.7m of 27.6% Zn+Pb (15.7% Zn and 11.9% Pb), 92 g/t Ag , incl. 1.0m of 47.0% Zn+Pb (27.0% Zn and 20% Pb), 171 g/t Ag Deeper Cu-Ag Zone (70m extension from 25-3552-51) 7.5m of 22 g/t Ag and 0.79% Cu (starting from 582m downhole), incl. 3.5m of 35 g/t Ag and 1.28% Cu Assays from downhole intervals 379m to 579m and 593m to 609m are pending 25-3552-51  – Remaining assays from this hole returned three zones of mineralization from the Deeper Cu-Ag target (starting from 434m downhole) 1.9m of 17 g/t Ag, 0.28% Cu and 1.8m of 59 g/t Ag, 0.61% Cu, 0.14% Sb and 2.8m of 30 g/t Ag, 0.72% Cu (incl. 1.0m of 78 g/t Ag, 1.91% Cu, 0.16% Sb ) Cu-Ag mineralization announced today provides additional evidence of steeply south-dipping fault zones, interpreted to be continuation of Cu-Ag bearing fault zones intersected 350m to the NE (in holes 25-3552-40, -44 and -47, announced in 2025), adding support to hypothesis that Cu-Ag bearing fault zones may extend along strike length of entire Ballywire discovery 25-3552-52  – Extends mineralized strike length of the Ballywire discovery by approx. 600m from 2.6km to 3.2km, by intersecting 22m
