TAGUAS PROJECT – FIRST DEEP DRILLING PROGRAM

The first drill hole has reached a depth of 650 metres of the planned 1,500 metres. Drilling has intersected the upper portion of the epithermal system as anticipated, comprising several bands of polymictic hydrothermal breccias locally cut by quartz–pyrite–enargite veinlets. The final metres drilled exhibit sericitic alteration.

Drilling commenced in January 2026 as part of an initial approximately 4,500-metre program utilizing one drill rig, with completion expected by April 2026, subject to drilling conditions and logistics. The current hole is targeting the core of a low-resistivity anomaly identified by a recent geophysical survey (see Image 1; for further details, see the Company's news release dated January 28, 2026), located between Cerro Taguas Norte and Cerro Campamento.

The program is designed to evaluate the potential deep porphyry copper-gold system at the Taguas Property for the first time. Deep drilling will test zones exhibiting geological and geophysical characteristics commonly associated with copper–gold porphyry systems.

Drill results from the program are expected to be released as they become available, subject to analysis and verification.
