GSP Hyperspectral Analysis Demonstrates Potential New Porphyry
Sources of Mineralization Across the Combined Alwin-Mer
Properties
News Release - Vancouver, British Columbia – December 16, 2025: GSP Resource Corp. (TSX-
V: GSPR / FSE: 0YD / OTC: GSRCF ) (the “ Company” or “ GSP”) announces the receipt of
surface rock sample visible and short wave infra-red (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 towards the margins of
the hydrothermal system (away from the Valley Pit 4 km to the east). These results are consistent
with those of Alva-Jimenez1 (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.

Porphyry Cu-Mo District, BC, Canada, UBC, M.Sc. Thesis, 249p.
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 deposit2.
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 6 km) from Valley, further supporting the potential of an undiscovered porphyry system at
Alwin-Mer.

Methodology and QA/QC
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% passing 2 mm, followed by pulverizing of a 250 -gram split to 85% passing 75
microns. VIS-SWIR hyperspectral analysis was performed on crush rejects at ALS using a
TerraSpec® 4 hr spectrometer. Spectral interpretation is com pleted 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 Corp. 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 Corp. 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.
