GSP SOIL GEOCHEMICAL RESULTS EXPAND SURFACE COPPER ZONE AT MER AND HIGHLIGHT NEAR SURFACE IN-PIT RESOURCE EXPANSION POTENTIAL AT ALWIN MINE

GSP Resource Corp. has received final soil geochemical sample analysis from its fall 2025 Alwin mine and Mer property geologic reconnaissance exploration program.

The 2025 Alwin-Mer results released today for 204 targeted grid soil geochemical samples form part of the larger 2025 Alwin-Mer geologic reconnaissance exploration program. Surface rock grab sample results released previously highlight the high-grade Apex zone that yielded assays, including 1.85 per cent copper, 348 grams per tonne silver and 2.6 g/t gold; in addition to the Mer zone returning widespread moderate copper values (see GSP Resource news release dated Nov. 26, 2025).

Compelling surface rock anomalies are augmented by shortwave infrared (VIS-SWIR) hyperspectral TerraSpec analysis yielding muscovite and chlorite compositions at Mer indicative of a high-temperature proximal porphyry environment and peripheral porphyry environment at Alwin. Together, these results support the potential for an undiscovered porphyry system.

Alwin-Mer grid soils targeting the Mer, Alwin mine south and Little OK Lake areas. Highlights of the soil geochemical surveys are as follows:

• Soil sampling at Mer targeted an area of historic trenching and about 1970s percussion drilling. Of the 157 soils collected at Mer, a total of 31 samples returned greater than 60 parts per million copper, including eight samples greater than 150 parts per million copper and up to 315 ppm Cu. The soil results define an approximately 175-by-120-metre apparently northwest-trending copper anomaly extending northwest of the focus of historic drilling and trenching. In this area, four sequential soil samples spaced at 20-metre intervals yielded copper values of 158, 206, 190 and 252 ppm copper, indicating the Mer copper anomaly is open to the northwest of the area historically explored.
• At the Alwin mine, soils targeted near-surface copper drill intercepts occurring at the edge of the Alwin mine pit shell where 1968 drilling (hole 68-45) returned two metres averaging 4.4 per cent copper, which was followed up by the company within drill hole AM-21-02 located 50 metres to the southeast that returned 1.8 m averaging 3.2 per cent copper. At Alwin mine south, a total of nine samples returned greater than 60 ppm copper, including five samples returning greater than 100 ppm copper and up to 175 ppm copper. The highest soil values occur east of the surface projection of mineralization within 68-45 and AM-21-02 indicating that expansion of soil geochemical coverage and/or excavated trenching in this area of no outcrop and comparatively limited drilling are warranted to further evaluate resource expansion potential along the south pit wall of the at Alwin mine.
• In the Little OK Lake area, about 2007 historic soil sampling by San Marco Resources Inc. yielded copper values as high as 4,400 ppm, which were thought to be related to site contamination. However, the area of the historic anomaly is forested and appears relatively undisturbed. Current soil sample results returned the highest values, across the entire grid area with 21 of 25 samples returning greater than 100 ppm copper, including 14 samples greater than 200 ppm copper and up to 950 ppm copper. Following receipt of the Little OK Lake soil results, additional research and compilation was completed, including accessing historic aerial photography, which indicted a significant expansion and change in the size and configuration of the outlet location of the now reclaimed historic Alwin mine tailings pond. Based on the prior about 1970s Little OK Lake configuration, it seems likely the anomaly is related to transported tailings material.

Methodology and quality assurance/quality control

The analytical work reported on herein was performed by ALS Global, Kamloops, Canada. ALS is an ISO-IEC 17025:2017 and ISO 9001:2015 accredited geoanalytical laboratory, and is independent of GSP Resource and the qualified person. Soil samples collected from the B-horizon to a maximum of 30-centimetre depth and subsequently dried and sieved. Base and precious metal was determined through aqua-regia digestion 51-element ICP-MS analysis and 30-gram gold fire assay with AAS finish.

GSP Resource follows industry standard procedures for the work carried out on the Alwin mine project, with a quality assurance/quality control program. Duplicate soil samples were collected at one-20th frequency and inserted into the sample sequence sent to the laboratory for analysis to assess repeatability. In addition, GSP Resource has relied on the internal quality assurance/quality control 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 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.
