GSP Commences Phase 1 Drilling at Alwin-Mer - Targeting High-Grade Gold & Porphyry Copper, Highland Valley, BC

Executive Summary

• GSP Resource Corp. has commenced Phase 1 of its 2026 drilling program at the combined Alwin-Mer properties in the Highland Valley Copper Camp, British Columbia.
• The program targets follow-up high-grade gold mineralization at the Alwin property (building on late 2024 discoveries) and new porphyry copper targets at the Mer property.
• Phase 1 drilling is expected to total between 1,200 and 1,500 metres, with permits allowing for initial year-one diamond drilling and surface disturbance approved for expansion over the following four years.

Key Details

• Drilling Program Scope: Phase 1 of 2026 drilling has commenced, targeting 1,200–1,500 metres of diamond drilling across two distinct properties.
• Alwin High-Grade Gold Targets: Follow-up drilling will step out laterally and vertically from late 2024 discovery hole AM-24-06, which returned 5.04 g/t Au and 1.01% Cu over 7.90 m, including 22.93 g/t Au and 1.82% Cu over 1.64 m. Drilling aims to expand the high-grade gold footprint and test modelled copper lodes in the structural footwall to the north.
• Alwin Resource Context: The project hosts an inferred mineral resource of 1.46 Mt at 1.08% Cu (yielding 34.6M lbs Cu). The new high-grade gold discovery sits 40 m below the current resource pit shell, potentially augmenting open pit and underground mineable copper resources. Mineralization is marked by intense black chlorite-sericite alteration.
• Mer Porphyry Copper Targets: A new porphyry target was defined via historic data compilation and recent rock/grid soil sampling, identifying a ~175 x 120 m Cu anomaly open to the northwest. Rock sampling returned 0.14–1.02% Cu (avg 0.4%), and TerraSpec® analysis indicates a higher-temperature proximal porphyry environment.
• Mer Property & Permitting: The 185-hectare Mer Property is located ~1.5 km NW of Alwin, surrounded by Teck Resources’ Highland Valley Copper claims. The permit covers an initial year-one diamond drilling program, with surface disturbance approved to support anticipated expansion drilling over the next four years.
• Historical Drilling (Mer): Explored 1965–1971 by Cleveland Mining & Smelting. Historic percussion and diamond drilling defined a 70 x 120 m NE-trending porphyry Cu-Mo zone. Historic holes returned averages of 0.47%–0.53% Cu over various intervals, and a single diamond hole intersected 0.29% Cu over 24 m from 9 m depth. No significant exploration has occurred since the early 1970s.
• Qualified Person: Christopher I. Dyakowski, P. Geo., Director of the Company.

Notable Quotes

• Simon Dyakowski, President & CEO: “GSP has commenced 2026 drilling at a time of renewed exploration and development activity in the Highland Valley Copper Camp, with copper trading near record highs. Phase 1 pairs first-pass porphyry copper drilling at Mer with follow-up to our 2024 high-grade gold discovery at Alwin — two distinct targets within a single camp that we believe each offer meaningful upside as we advance the projects.”
