Update on Stonepark

Arkle Resources (AIM: ARK) provides an update on the Stonepark Zinc Project in Limerick (the "Project"), where Arkle is a 22.36% interest holder alongside Group Eleven Resources Corp ("Group Eleven") which holds 77.64% in the Project.

Included in Group Eleven's interim financial statements, released today, was an update on the Project, which stated:

"At Stonepark, the Company's most recent exploration drilling at the Carrickittle West Prospect (a 'mirror-image' lookalike target to Glencore's Pallas Green deposit a few kilometres to the north), announced in Q2 2025, identified the Kilteely and Bruff prospects as hosting priority follow-up drill targets. The Company has commenced additional drilling of one hole at Stonepark in the fourth quarter of 2025, with follow-up holes at Carrickittle West to be drilled in 2026."

The Company will provide further updates on the Project in due course.
