• Rushed surface sample assays from new targets recently explored at Alwin and Mer Properties included assays of 348 g/t Silver and 12% Copper  

• Additional rock and soil sample results are pending 

News Release - Vancouver, British Columbia – TheNewswire - October 28, 2025:  GSP Resource Corp. (TSX-V: GSPR / FSE: 0YD / OTC: GSRCF) (the “Company” or “GSP”) announces initial rush assay results from its recently completed Fall 2025 geologic reconnaissance targeting program at the Mer Porphyry and Al conductor targets, in addition to the newly discovered high-grade silver-copper Apex target within the Alwin Mine Zone (see GSP resources Corp. News release dated September 16, 2025).

 

An initial 10 select surface rock grab sample were submitted for rush assay with highlights of the initial samples as follows (Figure 1, and Table1):

 

• 348 grams-per-tonne (g/t) silver (Ag), 11.9% copper (Cu); and 104 g/t Ag, 1.2 g/t gold, and 4.2% Cu from the Apex Zone.  

• Alwin Mine and nearby historic “Area D” trenches yielded high grade assays of 5.5% Cu and 35 g/t Ag, and 1.6% Cu in outcrop and trench float.   

• Little OK Lake float exposed in road cuts yields 2.58% Cu and 1.62% Cu. 

• Mer Porphyry Zone returned outcrop samples returning 0.52% Cu and 0.33% Cu. 

 

Details of Current Exploration

 

The 2025 Mer and Alwin Mine geologic reconnaissance program comprised of the collection of 60 surface rock outcrop and float samples as well as 204 targeted grid soil samples.  This exploration program represents the first surface work to be conducted on expansionary exploration targets outside the Alwin Mine resource area since 2008.  Within the Alwin Property, there are numerous historic trenching and drilling areas for which there are little to no assay documentation available.  Much of the historic exploration at Alwin occurred during the 1960’s, 70’s and 80’s.  Recently, clear-cut logging and road construction has re-opened access to these historic exploration sites.

 

Historic Data Compilation Yields New Targets

 

Historic data compilation for the Mer porphyry and Apex targets highlights the significant near mine exploration potential that remains.

 

At Mer, ca. 1970’s diamond and percussion drilling and extensive caterpillar trenching sites were re-located (see GSP Resource Corp. news release dated March 13, 2025) and an area of malachite-chalcopyrite mineralized granodiorite was sampled, and a detailed soil grid was established to expand the potential drilling target (Image 1).

 

At the recently re-discovered Apex Zone, located 40 metres off a modern logging road, historic 1977 diamond drill logs lacking assay records documented a 2.6 metre core-width chlorite-sericite, pyrite chalcopyrite mineralized alteration zone including a quartz-carbonate vein containing 6-10% chalcopyrite. The trench zone targeted by the 1977 drilling was located with the aid of historic geologic maps and modern satellite imagery (Image 2).

Methodology and QA/QC

The analytical work reported on herein was performed by ALS Global (“ALS”), Vancouver, Canada. ALS is an ISO-IEC 17025:2017 and ISO 9001:2015 accredited geoanalytical laboratory and is independent of GSP Resource Corp. and the QP. Rock samples were subject to crushing at a minimum of 70% passing 2 mm, followed by pulverizing of a 250-gram split to 85% passing 75 microns. Base and precious metals were determined via four-acid digestion 33 element ICP-AES geochemistry and overlimit values for copper (>1%) and silver (100 g/t) were analyzed via four-acid digestion ICP-AES or AAS.

 

Rock grab samples are selective by nature and as such are not necessarily representative of mineralization or grades across defined intervals. Continued exploration including but not limited to trenching and/or diamond drilling will be required to confirm the grade and continuity of mineralized zones.  GSP Resource Corp. has relied on the internal quality assurance/quality control (QA/QC) measure of ALS which includes the insertion of standard, blank and duplicate samples into the sample stream to confirm the accuracy of the reported results. GSP Resource Corp. detected no significant QA/QC issues during review of the data, and is not aware of any sampling, or other factors that could materially affect the accuracy of the results.
