GSP Samples 348 g/t Silver and 12% Copper at New, Near Mine, Expansion Targets at Alwin Mine and Mer Properties

GSP Resource Corp. announced initial, rushed assay results from a fall 2025 surface reconnaissance and sampling program at its Alwin and Mer properties. The program was designed to follow up on geophysical work and define new drill targets.

Key grab sample results include: - Sample E01984 (Apex Zone trench float): 348 g/t Silver (Ag), 11.85% Copper (Cu), and 0.19 g/t Gold (Au). - Sample E01985 (Apex Zone trench float): 104 g/t Ag, 4.14% Cu, and 1.18 g/t Au. - Sample E02007 (Alwin Mine outcrop): 35 g/t Ag and 5.52% Cu.

The company notes that rock grab samples are selective by nature and not necessarily representative of mineralization over defined intervals.

This news is a routine but positive step in the company's exploration timeline. It directly follows the announced field investigation program from September 16, 2025, demonstrating effective execution.

• Progression of Strategy: Over the past year, GSP has systematically advanced the Alwin project. After establishing an initial NI 43-101 resource (Dec 2024) and hitting high-grade gold in drilling (Jan/Feb 2025), the company identified a large, deep geophysical anomaly suggestive of a porphyry source (Aug 2025). This latest news provides the first surface geochemistry results from follow-up on these new targets. The high-grade copper and silver values in the "Apex Zone," a new target area, are encouraging and confirm the potential of areas outside the known resource.

• Impact on Valuation: The impact is minimal from a fundamental valuation perspective. High-grade grab samples are positive indicators but do not constitute a discovery. They serve to generate prospective drill targets and de-risk a future drill program to a small extent. The market for junior explorers is often driven by drill results, not surface samples. Therefore, while positive, this news does not materially change the company's asset base until these targets are drilled and proven.

• Expectations: The results are in line with or slightly exceed what one would hope for from a first-pass sampling program on a prospective target. The grades are high enough to create excitement and justify follow-up drilling. However, the use of the term "rushed assays" is a promotional flag; a critical analyst must wait for the full suite of results to get a complete picture.

Overall, this is a successful and expected outcome of the planned exploration program. It adds credibility to the new targets generated from geophysical work but does not change the company's immediate risk profile or financial situation.

GSP Resource Corp. is a Canadian-based junior mineral exploration company. Its flagship asset is the 100%-owned Alwin Mine Project, a past-producing high-grade copper-silver-gold mine located in the Highland Valley Copper Camp of British Columbia. The property is adjacent to Teck Resources' Highland Valley Copper Mine, one of the largest copper mines in Canada.

In December 2024, GSP published its first NI 43-101 compliant Inferred Mineral Resource Estimate for Alwin, totaling 1.46 million tonnes at 1.08% copper, containing 34.6 million pounds of copper. The company is focused on expanding this resource and exploring for a potential underlying porphyry copper system, which it believes was the source of the high-grade vein mineralization historically mined. The company also owns the nearby Mer property, a porphyry copper exploration target.
