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

(TheNewswire)

Vancouver, British Columbia – TheNewswire - December 16, 2025: GSP Resource Corp. ( TSX-V: GSPR / FSE: 0YD / OTC: GSRCF ) (the“ Company ” or “ GSP ”) announces the receipt of surface rocksample visible and short wave infra-red (VIS-SWIR) hyperspectralTerraSpec® analysis from its recently completed Fall 2025 Alwin Mineand Mer property geologic reconnaissance.  The Company also announcesthat geochemical analytical results for an additional 204 targetedgrid soil samples are pending.

The VIS-SWIR hyperspectral data returned from acrossthe Alwin Mine and Mer properties reveal important spatial patternsthat provide strong evidenceof potential porphyry copper mineralization vectors.  Highlights of the recently completed hyperspectralstudies area as follows:

• The Alwin Mine has yielded phengitic muscovitecompositions and magnesium-rich chlorite consistent with a peripheralporphyry environment;

• Mer pargonitic muscovite and magnesium-iron chloritecompositions suggesting a higher temperature proximal porphyryenvironment;

• Presence of pervasive muscovite containing chalcopyriteand bornite, typical of the potassic core at Valley, suggests Alwinmay represent the upper parts of a still deeper porphyrysystem.

• The presence of higher temperatureproximal porphyry signature at Mer, which lies further from the ValleyDeposit than Alwin further supports the potential of an undiscoveredporphyry system at Alwin-Me r

Details of the HyperspectralStudy

Hyperspectral data proximal to the Alwin Mine yieldedphengitic (K-rich) muscovite indicating that the high-gradecopper-silver veins present there are consistent with a peripheralporphyry environment.  In contrast at Mer, pargonitic muscovitepredominantly suggests a higher temperature proximal porphyryenvironment.  Alwin-Mer chlorite compositions reveal a similardistal-proximal pattern, with relatively magnesium-rich chloritesuggesting a porphyry margin environment, versus magnesium-ironchlorite compositions indicating closer proximity to the core of aporphyry system.

Massive pale green phengitic muscovite andquartz-sulphide veins present at the Alwin Mine are interpreted toreflect decreasing temperature and more neutral pH conditions towardsthe margins of the hydrothermal system (away from the Valley Pit 4 kmto the east).  These results are consistent with those ofAlva-Jimenez 1 (2011), work thatwas part of the larger “Footprints of Porphyry Cu Deposits” study,who observed that the Alwin Mine has similar muscovitic compositionsto those found at the margin of the Valley deposit and interveningBethsaida zone.

Significantly, Alva-Jimenez noted similarities betweenAlwin and Valley, including many of the same textural features such aspervasive muscovite containing chalcopyrite and bornite, typical ofthe potassic core at Valley.  The apparent mismatch in muscovitecompositions led to speculation the Alwin system may represent the upper parts of a still deeperporphyry system similar to the Valley deposit 2 .

The observation that Mer muscovite-chloritecompositions are consistent with a higher temperature porphyryproximal environment is difficult to reconcile given that Mer occursfurther still (greater than 6 km) from Valley, further supporting the potential of an undiscoveredporphyry system at Alwin-Mer .

Methodology and QA/QC

The analytical work reported on herein was performed byALS Global (“ALS”), Vancouver, Canada. ALS is an ISO-IEC17025:2017 and ISO 9001:2015 accredited geoanalytical laboratory andis independent of GSP Resource Corp. and the QP. Rock samples weresubject to crushing at a minimum of 70% passing 2 mm, followed bypulverizing of a 250-gram split to 85% passing 75 microns. VIS-SWIRhyperspectral analysis was performed on crush rejects at ALS using aTerraSpec® 4 hr spectrometer. Spectral interpretation is completedusing IMDEX aiSIRIS™ software, and raw spectral files reported inASD and ASCII format. Percentages of mineral results reported byaiSIRIS™ represent the spectral contribution (SC) of the mineralswith diagnostic features in the VIS-SWIR wavelength region. Values arenot normative or modal mineralogy percentages.

GSP Resource Corp. has relied on the internal qualityassurance/quality control (QA/QC) measure of ALS which includes theinsertion of standard, blank and duplicate samples into the samplestream to confirm the accuracy of the reported results. GSP ResourceCorp. detected no significant QA/QC issues during review of the data,and is not aware of any sampling, or other factors that couldmaterially affect the accuracy of the results.
