GSP RESOURCE CORP. ENGAGES WESTERN EXPLORATION DIAMOND DRILLING FOR PHASE 1 DRILLING AT ALWIN-MER PROPERTIES TARGETING HIGH-GRADE GOLD EXPANSION & PORPHYRY COPPER, HIGHLAND VALLEY, BC

GSP Resource Corp. has engaged Western Exploration Diamond Drilling Ltd. of Logan Lake, B.C., for the first phase of 2026 drilling at its combined Alwin-Mer properties located in the Highland Valley copper camp of British Columbia. Drilling crews are expected to mobilize over the next 10 days with drilling expected to commence shortly thereafter. The initial phase of 2026 drilling is planned to target both the potential for porphyry copper at the Mer property, as well as follow-up drilling to a gold discovery drilled at Alwin in late 2024. The first phase of drilling is expected to total between 1,200 to 1,500 metres. Subject to the results of the first phase of drilling and market conditions, the company expects to plan and initiate a second phase of drilling during the fall exploration season.

Alwin high-grade gold targets

Phase 1 drilling at the Alwin high-grade gold target is expected to follow up on the discovery of high-grade gold values drilled in late 2024 in stepout hole AM-24-06 that yielded 5.04 grams per tonne (g/t) gold (Au) and 1.01 per cent copper (Cu) over 7.90 metres (m); including 22.93 g/t Au and 1.82 per cent Cu over 1.64 m.

The Alwin project currently hosts an inferred mineral resource comprising 1.46 million tonnes (Mt), at an average grade of 1.08 per cent Cu, yielding 34.6 million pounds of Cu. Potentially significant silver and gold values have long been known at Alwin, however a lack of historic assays for these metals prior to drilling by GSP has precluded their inclusion in resource estimation. The new discovery within west-side stepout drill hole AM-24-06 at a depth of 40 m below the current resource pit shell presents an opportunity to augment existing open pit and underground mineable copper resources with high-grade gold values.

Significantly, high-grade gold values in AM-24-06 occur in a 1.64 m core width interval, which includes an individual sample of 0.84 m assaying 35.1 g/t Au (1.02 ounces/ton), within the interpreted hanging wall of a broader 7.9 m core width copper-gold-silver zone.

The occurrence of high-grade gold values, below the vertical projection of existing "three zone" modelled copper resources, affirms the company's belief that these two contrasting mineralization styles are structurally and genetically linked, and can be successfully targeted within the context of the current Alwin mine geological model. Additionally, the Alwin high-grade gold mineralization is visually distinct from the broader copper zones and is marked by the presence of intense texturally destructive black chlorite-sericite alteration.

As part of the first phase of 2026 drilling, GSP is planning to step out and potentially expand the footprint of important high-grade gold mineralization within AM-24-06. The drilling is designed to test both laterally and vertically beyond AM-24-06 to provide additional intercepts to confirm the structural setting, as well as to extend the depth of drill holes to test additional modelled copper lodes within the structural footwall to the north that are equally as prospective.

Mer porphyry copper drill targets

GSP also plans to drill a new porphyry target defined through compilation of historic drilling data, and recently advanced by follow-up rock and grid soil sampling as part of the first phase of 2026 drilling. Follow-up soil and rock sampling at Mer targeted the area of historic drilling and defined an approximately 175-by-120-metre copper anomaly that is open to the northwest. Rock sampling at the historic Mer showing yielded 12 samples returning between 0.14 to 1.02 per cent Cu, and averaging 0.4 per cent Cu; in addition to TerraSpec analysis yielding pargonitic muscovite and magnesium-iron chlorite compositions suggesting a higher temperature proximal porphyry environment (please see news release dated Nov. 26, 2025, for soils and rocks; and Dec. 16, 2025, for TerraSpec results).

The Mer property comprises 185 hectares in the Kamloops mining division, located approximately 1.5 kilometres NW (northwest) of GSP's Alwin mine project and is surrounded by Teck Resources' Highland Valley copper claim group directly west and south of the Highland Valley copper mine's active operations. The Mer property hosts a copper exploration target zone located NW of the company's Alwin mine high-grade copper-silver-gold target zone.

The permit provides for an initial year-one diamond drilling program, followed by permitting sufficient surface disturbance to support anticipated expansion diamond drilling within the following four years of the permit. The property is well accessed via existing logging roads that traverse the proposed drilling area where prior logging activities and excavator trenching has exposed a zone of copper mineralization at surface.

About the Mer claims

The Mer claims were the subject of intensive exploration by the Cleveland Mining & Smelting Co. Ltd. between the years 1965 and 1971. During that time exploration within the current Mer and surrounding claims now held by Teck Highland Valley Copper Corp. comprised geochemical and IP/resistivity geophysical surveys, geologic mapping, bulldozer trenching, completion of 16 percussion drill holes totalling 610 metres (m), and a single 150 m diamond drill hole targeting the Mer showing.

Percussion and diamond drilling were reported to define a 70-by-120-metre northeast-trending porphyry copper-molybdenum zone characterized by disseminated chalcocite, chalcopyrite, bornite and molybdenite mineralization, and associated biotite and sparse potassic alteration.

At the Mer showing, historical percussion drill holes 1, 3, 15 and 16, forming a 70 by 40 m diamond pattern in plan, returned values of nine m averaging 0.47 per cent copper (Cu); 30 m averaging 0.53 per cent Cu; 15 m averaging 0.50 per cent Cu; and 21 m averaging 0.51 per cent Cu respectively, commencing at down hole depths ranging from six to 18 m.

A single diamond drill hole was centered on the percussion drill holes and intersected a zone of chalcocite mineralization within biotite and potassic altered granodiorite intrusive rocks averaging 0.29 per cent Cu over 24 m from a downhole depth of nine m. The zone of mineralization remains open to the north and west.

No significant exploration has been reported within this project since the initial work programs ending in the early 1970s. Given the presence of drill-confirmed porphyry copper-molybdenum mineralization, a location six kilometres west of the Valley Pit at Teck Resources Ltd.'s Highland Valley copper operations, and its position within the Chataway and Guichon granodiorite phases of the Guichon batholith, the Mer project is a high priority for follow-up exploration.
