GSP HYPERSPECTRAL ANALYSIS DEMONSTRATES POTENTIAL NEW PORPHYRY SOURCES OF MINERALIZATION ACROSS THE COMBINED ALWIN-MER PROPERTIES

GSP Resource Corp. has received surface rock sample visible and short wave infrared (VIS-SWIR) hyperspectral TerraSpec analysis from its recently completed fall 2025 Alwin mine and Mer property geologic reconnaissance. The company also announces that geochemical analytical results for an additional 204 targeted grid soil samples are pending.

The VIS-SWIR hyperspectral data returned from across the Alwin mine and Mer properties reveal important spatial patterns that provide strong evidence of potential porphyry copper mineralization vectors. Highlights of the recently completed hyperspectral studies area as follows:

• The Alwin mine has yielded phengitic muscovite compositions and magnesium-rich chlorite consistent with a peripheral porphyry environment.
• Mer pargonitic muscovite and magnesium-iron chlorite compositions suggesting a higher temperature proximal porphyry environment.
• Presence of pervasive muscovite containing chalcopyrite and bornite, typical of the potassic core at Valley, suggests Alwin may represent the upper parts of a still deeper porphyry system.
• The presence of higher-temperature proximal porphyry signature at Mer, which lies further from the Valley deposit than Alwin further supports the potential of an undiscovered porphyry system at Alwin-Mer.

Details of the hyperspectral study

Hyperspectral data proximal to the Alwin mine yielded phengitic (K-rich) muscovite indicating that the high-grade copper-silver veins present there are consistent with a peripheral porphyry environment. In contrast at Mer, pargonitic muscovite predominantly suggests a higher-temperature proximal porphyry environment. Alwin-Mer chlorite compositions reveal a similar distal-proximal pattern, with relatively magnesium-rich chlorite suggesting a porphyry margin environment, versus magnesium-iron chlorite compositions indicating closer proximity to the core of a porphyry system.

Massive pale green phengitic muscovite and quartz-sulphide veins present at the Alwin mine are interpreted to reflect decreasing temperature and more neutral pH conditions toward the margins of the hydrothermal system (away from the Valley pit four kilometres to the east). These results are consistent with those of Alva-Jimenez 1 (2011), work that was part of the larger "Footprints of Porphyry Cu Deposits" study, who observed that the Alwin mine has similar muscovitic compositions to those found at the margin of the Valley deposit and intervening Bethsaida zone.

Significantly, Alva-Jimenez noted similarities between Alwin and Valley, including many of the same textural features such as pervasive muscovite containing chalcopyrite and bornite, typical of the potassic core at Valley. The apparent mismatch in muscovite compositions led to speculation the Alwin system may represent the upper parts of a still deeper porphyry system similar to the Valley deposit.

The observation that Mer muscovite-chlorite compositions are consistent with a higher-temperature porphyry proximal environment is difficult to reconcile given that Mer occurs further still (greater than six km) from Valley, further supporting the potential of an undiscovered porphyry system at Alwin-Mer.

Methodology and QA/QC (quality assurance/quality control)

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 per cent passing two millimetres, followed by pulverizing of a 250-gram split to 85 per cent passing 75 micrometres. VIS-SWIR hyperspectral analysis was performed on crush rejects at ALS using a TerraSpec four hr spectrometer. Spectral interpretation is completed using IMDEX aiSIRIS software, and raw spectral files reported in ASD and ASCII format. Percentages of mineral results reported by aiSIRIS represent the spectral contribution (SC) of the minerals with diagnostic features in the VIS-SWIR wavelength region. Values are not normative or modal mineralogy percentages.

GSP Resource 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 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.
