Vancouver, British Columbia – TheNewswire -- April 22, 2026:   GSP Resource Corp. ( TSX-V: GSPR / FSE: 0YD / OTC: GSRCF ) (the “ Company ” or “ GSP ”) announces it has successfully received a 5-year multi-year area based (MYAB) drilling permit with respect to the Mer Property in the Highland Valley Copper Camp of British Columbia.

With the approval of the Mer MYAB, the Company can now move forward with planned diamond drilling of a new porphyry target defined through compilation of historic drilling data, and recently advanced by follow-up rock and grid soil sampling.  Follow-up soil and rock sampling at Mer targeted the area of historic drilling and defined an approximately 175 x 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% Cu, and averaging 0.4% 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 November 26, 2025, for soils and rocks; and December 16, 2025 for Terraspec results).

The Mer Property comprises 185 hectares in the Kamloops Mining Division, located approximately 1.5 km NW of GSP’s Alwin Mine Project and is surrounded by Teck Resource’s Highland Valley Copper claim group directly west and south of the Highland Valley Copper Mine’s active operations 1 ( Figure 1 ).  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 ( Figure 2 ).

The Company plans to announce the details of a drill program expected to commence in Q2 2026 over the coming weeks, subject to available funds, and board approval.

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 Corporation comprised geochemical and IP/resistivity geophysical surveys, geologic mapping, bulldozer trenching, completion of 16 percussion drill holes totaling 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 x 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 x 40 m diamond pattern in plan returned values of 9 m averaging 0.47% copper (Cu); 30 m averaging 0.53% Cu; 15 m averaging 0.50% Cu; and 21 m averaging 0.51% Cu 2 respectively, commencing at downhole depths ranging from 6 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% Cu over 24 m from a downhole depth of 9 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 1970’s.  Given the presence of drill confirmed porphyry copper-molybdenum mineralization, a location 6 kilometers west of the Valley Pit at Teck Resource Limited’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.
