GSP Resource Corp. Receives Hyperspectral Analysis Results from Alwin Mine and Mer Property

Vancouver, British Columbia — December 16, 2025 — Leads & Copy — GSP Resource Corp. (TSX-V: GSPR / FSE: 0YD / OTC: GSRCF) has received surface rock sample analysis from its Fall 2025 Alwin Mine and Mer property geologic reconnaissance. Geochemical analytical results for 204 targeted grid soil samples are pending.

Hyperspectral data from the Alwin Mine and Mer properties reveal patterns that provide evidence of potential porphyry copper mineralization vectors. At the Alwin Mine, phengitic muscovite compositions and magnesium-rich chlorite are consistent with a peripheral porphyry environment. At Mer, pargonitic muscovite and magnesium-iron chlorite compositions suggest a higher temperature proximal porphyry environment. The presence of pervasive muscovite containing chalcopyrite and bornite at Valley suggests Alwin may represent the upper parts of a still deeper porphyry system. The higher temperature proximal porphyry signature at Mer supports the potential of an undiscovered porphyry system at Alwin-Mer.

The analytical work was performed by ALS Global. Kristopher J. Raffle, P.Geo. (B.C.), principal and consultant of APEX Geoscience Ltd. reviewed and approved the scientific and technical information.
