GSP TARGETS NEW HIGH-GRADE GOLD DISCOVERY LEVERAGING EXISTING COPPER RESOURCES AT ALWIN MINE PROPERTY

GSP Resource Corp. has provided an overview of planned follow-up to the recent high-grade gold discovery made at the 100-per-cent-owned Alwin mine project in southwestern British Columbia (please see the summary news release dated Feb. 19, 2025). The recently completed drilling marked a sea change for the Alwin mine project with the discovery of high-grade gold values in stepout hole AM-24-06, which 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 (1). With analysis of the recent drill results now completed, GSP announces additional high-grade gold drill targets are planned for 2025.

The Alwin project currently hosts an inferred mineral resource comprising 1.46 million tonnes (t), at an average grade of 1.08 per cent Cu, yielding 34.6 million pounds of Cu (2). Potentially significant silver and gold values have long been known at Alwin, however, a lack of historical 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 40 m below the current resource pit shell presents an opportunity to augment existing open pit and underground minable 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 per ton (oz/t), within the interpreted hangingwall of a broader 7.9 m core width copper-gold-silver zone (3). The occurrence of high-grade gold values, below the vertical projection of existing 3 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.

For the 2025 exploration season , GSP is planning an initial phase of drilling designed to infill and potentially expand the footprint of important high-grade gold mineralization with 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 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.

The 2025 exploration season is also expected to pursue additional targets adjacent to the Alwin open-pit resource area, as well as near other mineral showings on the property. The upcoming exploration work is subject to financing and market conditions and the company's board of directors' discretion. GSP expects to announce further exploration plans to delineate additional precious metal and polymetallic exploration targets over the coming months approaching the spring and summer field season.

Simon Dyakowski, chief executive officer of GSP, commented: "The discovery of high-grade gold mineralization represents a unique opportunity to reframe the Alwin mine project in the context of its potential to host broader copper-plus-gold-silver resources. The resource expansion potential represented by these high-grade gold zones in the context of potential copper equivalence, if we can establish geologic continuity, cannot be understated."

About the Alwin mine project

The Alwin mine copper-silver-gold property is approximately 344 hectares and is located on the semi-arid, interior plateau in south-central British Columbia. The historic underground mine was developed over 500 m long by 200 m wide by 300 m deep. Production took place between 1916 and 1981 from five major subvertical high-grade copper mineralization zones totalling 233,100 tonnes that milled 3,786 tonnes of copper, 2,729 kilograms of silver and 46.2 kilograms of gold. The average diluted head grade was 1.5 per cent copper.

The Alwin project hosts a current inferred mineral resource comprising 1.46 million tonnes tonnes, at an average grade of 1.08 per cent Cu, yielding 34.6 million pounds of Cu (4).

The Alwin project is adjacent with the western boundary of Teck Resources' Highland Valley mine, the largest open-pit porphyry copper-molybdenum mine in Western Canada. Alteration and mineralization of the Highland Valley hydrothermal system extends westward from the Highland Valley mine onto the Alwin project (see GSP's news release dated Jan. 30, 2020).
