GSP Commences Field Investigations to Advance Alwin Mine and Mer Property Porphyry Targets

(TheNewswire)

News Release - Vancouver, BritishColumbia – TheNewswire - September 16, 2025: GSP Resource Corp. ( TSX-V: GSPR / FSE: 0YD / OTC:GSRCF ) (the “ Company ” or “ GSP ”) announces themobilization of field crews to the Alwin Mine and Mer properties tofollow-up on recently identified geophysical anomalies that areconsistent with a potential porphyry mineralization source.

The fall 2025 Alwin-Mer surface exploration program isdesigned to follow-up on current geophysical, regional porphyryfootprint alteration mapping, and historic drilling within theunderexplored area north of the Alwin Mine.  The 2025 explorationwill be comprised of rock geochemical sampling and reconnaissancegeologic alteration mapping within the northern Alwin and Mer claimsto aid in the development of future drill targets.  In addition, atthe Mer Property a soil geochemical grid will be completed over thehistoric drilling and trenching area to better define the potentialfootprint of copper-molybdenum mineralization (Figure 1).

The Company recently announced the results of a NSAMT(natural-source audio-frequency magneto-telluric) geophysical surveyat the Alwin Mine Property, which defined a conductive anomaly atdepth within the northern Alwin claims.  The conductive anomalyoccurs within a well-defined northwest trending porphyry associatedalteration zone extending northwest to the Company’s MerProperty 1 ( see GSP Resource Corp. news release datedAgut 12, 2025 ).

Historic drilling within the northern Alwin claims nearthe conductive anomaly yielded zones of porphyry-style coppermineralization returning 9.7 metres grading 0.55% copper within drillhole 08-06 2 , with furtherdrilling dating back to 1969 intersecting likely conductivetalc-kaolinite altered Bethsaida phase intrusive rocks.

Within the Mer Property, which is located 2.5 km to thenorthwest of the Alwin Property, the Company has submitted a 5-yearmulti-year area based (MYAB) permit application to the BritishColumbia Ministry of Mining and Critical Metals (“BC MMCM”).  Thepermit application was submitted in preparation for an initial phase 1drill program designed to follow up on a porphyry copper-molybdenumzone defined by historic percussion drilling that returned mineralizedintercepts including 0.53% copper over 30 metres ( see GSP Resource Corp. news release datedMarch 13, 2025 ).
