GSP COMMENCES FIELD INVESTIGATIONS TO ADVANCE ALWIN MINE AND MER PROPERTY PORPHYRY TARGETS

GSP Resource Corp. has mobilized field crews to the Alwin mine and Mer properties to follow up on recently identified geophysical anomalies that are consistent with a potential porphyry mineralization source.

The fall 2025 Alwin-Mer surface exploration program is designed to follow up on current geophysical, regional porphyry footprint alteration mapping and historic drilling within the underexplored area north of the Alwin mine. The 2025 exploration will comprise rock geochemical sampling and reconnaissance geologic alteration mapping within the northern Alwin and Mer claims to aid in the development of future drill targets. In addition, at the Mer property a soil geochemical grid will be completed over the historic drilling and trenching area to better define the potential footprint of copper-molybdenum mineralization.

The company recently announced the results of a NSAMT (natural-source audio-frequency magneto-telluric) geophysical survey at the Alwin mine property, which defined a conductive anomaly at depth within the northern Alwin claims. The conductive anomaly occurs within a well-defined northwest-trending porphyry associated alteration zone extending northwest to the company's Mer property (see GSP Resource Corp. news release dated Aug. 12, 2025).

Historic drilling within the northern Alwin claims near the conductive anomaly yielded zones of porphyry-style copper mineralization returning 9.7 metres grading 0.55 per cent copper within drill hole 08-06, with further drilling dating back to 1969 intersecting likely conductive talc-kaolinite altered Bethsaida phase intrusive rocks.

Within the Mer property, which is located 2.5 km to the northwest of the Alwin property, the company has submitted a five-year multiyear area-based (MYAB) permit application to the British Columbia Ministry of Mining and Critical Metals (B.C. MMCM). The permit application was submitted in preparation for an initial phase 1 drill program designed to follow up on a porphyry copper-molybdenum zone defined by historic percussion drilling that returned mineralized intercepts including 0.53 per cent copper over 30 metres (see GSP Resource news release dated March 13, 2025).
