Enduro Metals Corporation has completed its inaugural diamond drill program at the Andrei copper-gold porphyry target, totaling 2,700 metres across seven drill holes within the 100%-owned Newmont Lake Project in British Columbia's Golden Triangle.

The completed program fell slightly short of the initial 3,000-metre target due to locally challenging drilling conditions and limited availability of drill-contractor personnel. The seven holes tested two principal chargeability anomalies within an open-ended, greater than four-kilometre combined chargeability and magnetic anomaly.

Initial geological observations from the northeast anomaly point to broader mineralised systems. Hole AD-03 intersected porphyry-style alteration and quartz-sulphide veining that increased in abundance downhole before terminating at 491 metres due to drilling conditions. Holes AD-04 and AD-06 encountered low-sulphidation epithermal-style quartz-carbonate-sulphide veining and brecciation between 63 metres and 92 metres, and at 436 to 444 metres downhole, respectively. Meanwhile, four holes tested the southwest anomaly, with AD-02 and AD-05 reaching their planned 505-metre depths while encountering chlorite and potassic alteration.

Phase 2 exploration is underway across the Newmont Lake property. Activities include a planned 20 line-kilometre induced polarization survey designed to extend geophysical coverage northeast of the Andrei drilling, alongside target-definition work at the FK, Southmore, Camp Zone, Burgundy, and 72 Zone areas.

Enduro expanded the Andrei target footprint in November 2025 by acquiring an adjacent 12-square-kilometre claim block from Romios Gold Resources for C$300,000.

“Completion of our inaugural drill program at Andrei has provided the first subsurface geological information across both of the principal chargeability targets within this extensive geological system. Initial observations indicate that the northeast anomaly is the more prospective. Of particular interest, AD-03 encountered porphyry-style alteration and quartz-sulphide veining that increases in abundance downhole, while AD-04 and AD-06 identified low-sulphidation epithermal-style veining and brecciation in the northeast target area. Our ongoing geological work and upcoming IP survey will provide additional information that, together with the pending assay results, will help us refine our geological model and prioritise the next phase of exploration at Andrei.”

All drill core assays from the 2026 inaugural program are currently pending and are expected to be received later in the year.
