STARR PEAK PLANS FOLLOW UP DRILL PROGRAM FOR HIGH POTENTIAL BHEM COPPER TARGET

Starr Peak Mining Ltd. plans to drill the deep target at Normetmar, resulting from the 2022 BHEM investigation. This target is positioned underneath Normetmar mineralization upper two zones, approximately 900 metres (m) to the west of the past-producing Normetal mine (10.1 million tonnes (t) at 2.15 per cent copper (Cu), 5.12 per cent zinc (Zn), 0.55 gram per tonne (g/t) gold (Au) and 45.25 g/t silver (Ag)), located in the Abitibi greenstone belt of Quebec.

Main target description

Deep-hole STE-22-123-W1 was drilled parallel to the favourable horizon down to a depth of 1,850 m vertical and intercepted sulphides along with the favourable mine sequence. Geophysic BHEM survey revealed a new untested anomaly (P123-W1) centralized at a vertical depth of 1,550 m and characterized by a mid-conductance of 150 siemens and dimensions of 150 m wide by 400 m long. This anomaly plate is the probable continuity of the mineralized system at depth underneath the historical mining drift from Normetal to Normetmar (level 1,270 m).

In comparison for the mineralization continuity, the past producing Normetal historical mine has been exploited down to a depth of 2,400 m and the mineralization system, historically described as richer in copper at depth and not ending completely at the bottom. Follow-up drill holes will be performed directly from the deep hole, optimizing drilling metres needed.

Johnathan More, chairman and chief executive officer of Starr Peak, commented: "This follow-up drill program underneath the Normetmar deep zone is an absolute must considering the past historic content of the Normetal mine. If we look at the upper zones drilled, we are seeing striking similarities in grade and thickness to the past-producing mine. The past-producing mine produced world-class copper grades at these deeper depths and therefore we have tremendously increased our view that the anomaly we will be drilling will potentially be similar in nature."

Additionally, geophysics targets at Copper Clive project will be the second priority for the drilling program. For details, see the news release dated Sept. 17, 2025: "VTEM Survey Highlights New High-Potential Area For Base Metals Discovery."

Geophysic BHEM survey means geophysical borehole electromagnetic survey, which is the science of recording and analyzing measurements of physical properties made in wells or test holes. This survey is a tool used to search for conductive mineral-bearing orebodies and allows the company to plan future drill holes based on those results. An anomaly is the interpreted result of a variation of the induced current in the bedrock.
