Vancouver, British Columbia – April 1st, 2026 – Starr Peak Mining Ltd. ("Starr Peak" or the "Company") (TSXV:STE) (OTCQX:STRPF) is pleased to announce plans to drill the deep target at Normetmar resulting from the 2022 BHEM1 investigation. This target is positioned underneath Normetmar mineralization upper two zones, approximately 900 meters to the West of the past-producing Normétal Mine (10.1Mt @ 2.15% Cu, 5.12% Zn, 0.55 g/t Au, 45.25 /t Ag), located in the Abitibi Greenstone Belt of Québec.
Main target description:
Deep hole STE-22-123-W1 was drilled parallel to the favourable horizon down to a depth of 1,850 meters vertical and intercepted sulfides along with the favourable mine sequence. Geophysic BHEM1 survey revealed a new untested anomaly (P123-W1.) centralised at a vertical depth of 1,550 meters and characterized by a mid-conductance of 150 siemens and dimensions of 150 meters wide by 400 meters long. This anomaly plate is the probable continuity of the mineralized system at depth underneath the historical mining drift from Normétal to Normetmar (Level 1,270m). (Figure 1)
In comparison for the mineralization continuity, the past producing Normétal historical mine has been exploited down to a depth of 2,400m and the mineralization system, historically described as richer in copper at depth and not ending completely at the bottom. See below Figure 1 showing the localization of the deep anomaly. Follow-up drill holes will be performed directly from the deep hole, optimizing drilling meters needed.
Johnathan More, Chairman and CEO 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 press release dated Sept 17th, 2025: VTEM Survey Highlights New High-Potential Area For Base Metals Discovery.
Geophysic BHEM1 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 ore bodies 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.
Qualified Person
Alexis Paulin Bissonnette, Ing. (OIQ 5037621), an independent Qualified Person as defined by Canadian NI 43-101 standards, has reviewed and approved the geological information reported in this news release. The Qualified Person has not completed sufficient work to verify the historic information on the Property, particularly in regards to historical drill results. However, the Qualified Person believes that drilling and analytical results were completed to industry standard practices. The information provides an indication of the exploration potential of the Property but may not be representative of expected results.

The Company wishes to caution that historical resources described above are historical. The historic resources are relevant to give a ballpark estimate of the potential of the property. Historical resources should not be relied upon. The key assumptions, parameters and methods used to prepare the historical estimate is not known and thus the difference between the historic estimates and NI 43-101 compliant estimates is also not known. The historical estimates used categories other than the ones set up in sections 1.2 and 1.3 of National Instrument 43-101, Standards of Disclosure for Mineral Projects. A qualified person has not reviewed the historical estimates and has not done sufficient work to classify the historical estimates as current mineral resources and Starr Peak is not treating the historical estimates as current mineral resources under National Instrument 43-101 and CIM Standards for mineral resources and reserves. Further exploration work needs to be done to correctly evaluate these historical resources. Additionally, the methodology of calculation is unknown by the qualified person.
Grab samples are selective by nature and the values reported may not be representative of the mineralized zone.
