GSP Resource samples up to 315 ppm Cu at Mer

Executive Summary

• GSP Resource Corp. released final soil geochemical results from its fall 2025 reconnaissance program at the Alwin Mine and Mer properties, highlighting significant copper anomalies and potential for resource expansion.
• At the Mer property, soil sampling defined a ~175-by-120-metre northwest-trending copper anomaly extending beyond historic drilling, with values up to 315 ppm Cu, suggesting the zone is open to the northwest.
• At the Alwin Mine, soil results support near-surface resource expansion potential along the south pit wall, while Little OK Lake area samples returned high copper values (up to 950 ppm) potentially linked to historic tailings material.

Key Details

• Mer Property Soil Results:
  • 157 soil samples collected targeting historic trenching and 1970s percussion drilling.
  • 31 samples returned >60 ppm copper.
  • 8 samples returned >150 ppm copper.
  • Highest value: 315 ppm copper.
  • Defined anomaly: ~175-by-120-metre, northwest-trending copper anomaly.
  • Sequential sampling (20m intervals) yielded 158, 206, 190, and 252 ppm Cu, indicating the anomaly is open to the northwest.
• Alwin Mine Soil Results:
  • Targeted near-surface copper intercepts at the edge of the pit shell.
  • Historic hole 68-45 returned 2m averaging 4.4% Cu.
  • Follow-up hole AM-21-02 (50m SE) returned 1.8m averaging 3.2% Cu.
  • Alwin Mine South: 9 samples >60 ppm Cu, including 5 samples >100 ppm Cu (up to 175 ppm Cu).
  • Highest soil values are east of the surface projection of mineralization, indicating expansion potential along the south pit wall where outcrop is limited.
• Little OK Lake Area Results:
  • 25 samples analyzed; 21 returned >100 ppm Cu.
  • 14 samples returned >200 ppm Cu.
  • Highest value: 950 ppm Cu.
  • Analysis suggests the anomaly may be related to transported tailings material from a reclaimed historic Alwin mine tailings pond, based on historic aerial photography review.
• Geological Context:
  • Shortwave infrared (VIS-SWIR) hyperspectral analysis identified muscovite and chlorite compositions at Mer, indicative of a high-temperature proximal porphyry environment.
  • Peripheral porphyry environment identified at Alwin.
  • Results support the potential for an undiscovered porphyry system.
• Methodology:
  • Analytical work performed by ALS Global (Kamloops, Canada).
  • Samples collected from B-horizon to max 30cm depth.
  • Analysis via aqua-regia digestion 51-element ICP-MS and 30-gram gold fire assay with AAS finish.
  • QA/QC included duplicate samples at 1-20th frequency; no significant issues detected.
