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

Group Eleven Resources Corp. (ZNG) announced that drill hole 26-2638-07 at its Stonepark project, which it owns 77.64%, intersected a new zone of zinc-lead-silver mineralization located 550m from the closest edge of the Stonepark Inferred Mineral Resource.

The upper interval returned 14.7m of 2.0% Zn+Pb (1.4% Zn, 0.6% Pb) from 461m downhole. This includes a higher-grade core of 6.3m @ 4.1% Zn+Pb, 2.8m @ 8.3% Zn+Pb, and 1.0m @ 21.7% Zn+Pb with 4 g/t Ag.

The lower interval returned 16.1m of 0.4% Zn from 507m, with thin higher-grade sub-intervals up to 2.5% Zn+Pb.

Both zones are hosted in the lowest 65m of Waulsortian Limestone. The hole was drilled to 894m to test deeper Cu-Ag, with assays pending. The nearest historic hole, TC-2638-030, located 150m NW, returned 3.2m of 4.4% Zn+Pb, providing some continuity but remaining very sparse.

Two more holes are planned to complete the current 2,700m campaign, while a larger 12,800m program is slated for late 2026/early 2027.

Stonepark remains a secondary asset for Group Eleven Resources Corp. (ZNG), with the primary value driver continuing to be the Ballywire discovery located 20 km away. Ballywire has consistently delivered higher-grade, thicker intercepts, drawing overwhelming market focus that propelled the stock price to $1.30 in May 2026.

The recent Stonepark result represents a positive step-out but does not change the resource estimate or confirm a new high-grade zone. Prior to the release, the stock had drifted from the $1.30 peak to approximately $0.83, suggesting waning enthusiasm. While a modest positive reaction is possible, sustained upside would require further news from Ballywire or a significantly stronger follow-up from Stonepark.

At this stage as an explorer with no revenue, funded through early 2027, an incremental hit at a secondary project serves as a data point that does not alter the primary thesis or materially de-risk the company.

Group Eleven Resources Corp. is a Canadian junior mineral explorer focused on zinc-lead-silver and copper in Ireland. Its flagship asset is the 100%-owned PG West project, which hosts the Ballywire discovery with a 3.2 km strike length. The company also holds a 77.64% interest in the Stonepark project, an advanced-stage inferred resource adjacent to Glencore’s Pallas Green deposit. The company has no production, no reserves, and no revenue.
