GSP Hyperspectral Analysis Demonstrates Potential New Porphyry Sources of Mineralization Across the Combined Alwin-Mer Properties

GSP Resource Corp. announced the receipt and interpretation of surface rock sample VIS-SWIR (Visible-Near Infrared to Short-Wave Infrared) hyperspectral analysis. This analysis was conducted on samples collected during the Fall 2025 geologic reconnaissance program at the Alwin Mine and Mer properties in British Columbia. The interpretation of this data indicates spatial patterns that are considered strong evidence of potential porphyry copper mineralization vectors. The company also stated that geochemical assay results for 204 targeted grid soil samples from the same program are pending.

This news represents a routine positive step in GSP Resource Corp.'s ongoing exploration efforts. The hyperspectral analysis is a specialized geological tool used to identify alteration minerals often associated with porphyry-style mineralization, thereby providing "vectors" for future targeting. It contributes to the geological understanding of the Alwin and Mer properties, building upon previous geophysical surveys (NSAMT survey at Alwin, 2025-08-12) and historical data that suggest porphyry potential.

However, it is crucial to understand that hyperspectral analysis provides indicative data about alteration, not direct assays of copper, gold, or silver grades, nor does it define a mineral resource. It is an exploration targeting method, a precursor to more definitive work. The real impact will come from the pending geochemical results from the 204 soil samples and, ultimately, from future drilling campaigns based on these cumulative insights.

In the context of historical news, GSP has been systematically advancing its exploration strategy, including completing a maiden NI 43-101 Inferred Mineral Resource for Alwin (2025-01-20), identifying high-grade gold zones (2025-01-16, 2025-02-19), conducting geophysical surveys (2025-06-24, 2025-08-12), and acquiring the Mer property (2025-01-06). The previous surface sampling results from October and November 2025 (e.g., 348 g/t Silver and 12% Copper, 2025-10-28; 87 g/t Silver, 3.3% Copper, & 2.3 g/t Gold, 2025-11-26) were more direct indicators of mineralization. This hyperspectral news, while positive for geological understanding, is less impactful than direct assay results or a resource update.

The market's reaction to this news was notably negative. The stock closed at $0.11 on December 15, 2025, and opened at $0.08 on December 16, 2025, the day of the news release, trading down to $0.08. This suggests that the market either anticipated more definitive results, or simply did not perceive this update as significant enough to warrant a positive re-rating. This counterintuitive price action on a seemingly positive exploration update highlights investor caution, potentially due to the early-stage nature of the results or underlying concerns about capital structure and dilution risk, which remain paramount for GSPR.

GSP Resource Corp. (TSX-V: GSPR) is a Canadian mineral exploration and development company primarily focused on copper, gold, and silver assets in British Columbia.

Flagship Project: Alwin Mine Copper-Gold-Silver Project * Location: South-central British Columbia, Canada, encompassing 344 hectares. It is strategically situated adjacent to Teck Resources' large Highland Valley Mine. * History: The Alwin Mine historically operated between 1916 and 1981, processing 233,100 tonnes of ore. It produced 3,786 tonnes of copper, 2,729 kilograms of silver, and 46.2 kilograms of gold, with an average diluted head grade of 1.5% copper. * Current Resource: On January 20, 2025, GSP filed a maiden NI 43-101 Inferred Mineral Resource Estimate (MRE) for the Alwin Project, with an effective date of September 16, 2024. This MRE reports 1.46 million tonnes at an average grade of 1.08% copper, for a total of 34.6 million pounds of contained copper. Approximately 66% of the contained copper is amenable to open pit mining, with the remaining 34% classified for underground mining. The MRE also noted significant potential for gold and silver contribution, which was not fully quantified due to a lack of historical assays. * Recent Exploration: * 2024 Drill Campaign: A seven-hole, 812-meter diamond drill program completed in late 2024 (results summarized February 2025) targeted extensions of known high-grade zones. This led to the discovery of a new high-grade gold zone in hole AM-24-06, yielding 5.04 g/t Au and 1.01% Cu over 7.90m, including 22.93 g/t Au and 1.82% Cu over 1.64m. Other holes confirmed significant widths of high-grade copper. * Geophysical Surveys: An NSAMT geophysical survey completed in August 2025 identified a large conductive anomaly at depth (600m-1,200m) in the northern Alwin property, interpreted as indicative of porphyry-style alteration. * Fall 2025 Reconnaissance: Ongoing field work including surface rock sampling and a soil geochemical grid, with hyperspectral analysis supporting porphyry potential.

Other Key Project: Mer Property * Location: 185 hectares, located approximately 1.5 kilometers northwest of the Alwin Mine project in the Highland Valley copper camp, surrounded by Teck Resources Ltd.'s claims. * Acquisition: GSP acquired a 100% interest in the Mer claims in April 2024. * History: Historical percussion drilling defined a porphyry copper-molybdenum zone, with intercepts such as 30 meters at 0.53% copper. * Recent Development: The permitting process for an initial five-year diamond drilling program has resumed, with an application submitted to the B.C. Ministry of Mining and Critical Metals (October 2025). Fall 2025 activities include a soil geochemical grid to define the mineralization footprint.
