GSP Advances AMT Geophysical Survey, Identifying a Large
Conductive Anomaly at Alwin Mine Property
• 2025 NSAMT survey has confirmed and strengthened the identification of
an untested deep conductive anomaly
• First property-wide geophysical survey in nearly 20 years
• Provides further evidence for an underlying porphyry source for the high-
grade copper-gold-silver mineralization at Alwin
News Release - Vancouver, British Columbia – August 12, 2025: GSP Resource Corp. (TSX-V:
GSPR / FSE: 0YD / OTC: GSRCF) (the “Company” or “GSP”) announces preliminary results of
its recently completed NSAMT (natural -source audio- frequency magneto -telluric) geophysical
survey at the Alwin Mine Property. The survey, the first property-wide geophysical survey in nearly
20 years, provides further evidence for an underlying porphyry source for the high- grade copper-
gold-silver mineralization at Alwin.
The results of the 2025 NSAMT survey have confirmed and strengthened the identification of an
untested deep conductive anomaly within the northern portion of the Alwin Property. The anomaly
is located 1.5 km northwest of the Alwin Deposit which hosts a current 34.6-million-pound inferred
copper resource. The conductive anomaly extends from 600-1200 metres depth, having dimensions
of approximately 600 x 750 metres, and 500- 1000 Ohm -m resistivity (Figures 1 and 2 ). This
conductive anomaly is significant for exploration of undiscovered porphyry- style mineralization as
it is situated along a well-defined northwest trending sodic-calcic fluid pathway passing through the
Company’s Mer Property, and southeast through the HVC Bethsaida Zone, Lornex and Highmont
deposits over 20 km1.
The presence of a deep er untested conductivity anomaly at Alwin is significant given that zones of
reduced resistivity can be associated with increased alteration, in particular porphyry- style quartz-
sericite-pyrite (phyllic) and clay (kaolinite) dominated alteration (notably at Endako and in the
Babine Porphyry district of BC). The range of observed resistivity of the Alwin anomaly is consistent
with those of quartz-sericite altered Endako quartz monzonite2.

porphyry deposit setting in the QUEST and QUEST-West Project Areas, Geoscience BC, Report 2011-1, p.17-32
Limited historic drilling during 2008, immediately south of the conductive anomaly, returned 9.7
metres grading 0.55% copper within drill hole 08 -063, with mineralization described as being
strong porphyry-style argillic-potassic alteration accompanied by quartz-chalcopyrite-bornite veins.
No follow-up drilling of this target has been ever completed. Two shallow drill holes completed in
1969 tested well above the anomaly and did not return significant mineralization; however, drill logs
noted numerous soft hematite talc -kaolinite gouge zones with Bethsaida granodiorite host rocks,
suggestive that the conductive anomaly at depth may represent altered intrusive.
The NSAMT survey at the Alwin Mine comprised a total of 10 east-west oriented survey lines for a
total of approximately 15 line-km. The 2025 NSAMT survey was designed to explore the presence
of deep seated conductive/resistive features beneath the Property and the shallow Alwin Deposit
Copper-Gold-Silver open pit and underground resource.
Historic 3D induced polarization / resistivity (IP/Res) surveys completed at Alwin during 2007,
though limited in their depth of investigation, reveal that the Alwin Deposit area is associated with a
zone of higher resistivity and weakly chargeable rocks. Significantly, the 2007 survey identified a
near surface conductive anomaly extending to a survey limited depth of ~200 metres in the northern
area of the Alwin Property flanked to the south by the relatively resistive and chargeable rocks.

Simon Dyakowski, CEO of GSP commented , “The discovery of a deeper conductive anomaly
within the northern area of the Alwin Project is another clear signal that the high-grade copper-
silver-gold mineralization at the Alwin Deposit may be related to a porphyry source at depth. The
Project’s location within the most important porphyry alteration fluid pathway corridors linking
GSP’s Mer Project, Al win Mine and HVC’s Bethsaida, Lornex and Highmont deposits further
reinforces our view of the compelling exploration upside at Alwin.”
About the Alwin Mine Project
The Alwin Mine Copper-Silver-Gold property is approximately 344 hectares and is located on the
semi-arid, interior plateau in south- central British Columbia. The historic underground mine was
developed over 500 m long by 200 m wide by 300 m deep. Production took place between 1916 to
1981 from five major subvertical high- grade copper mineralization zones totaling 233,100 tonnes
that milled 3,786 tonnes of copper, 2,729 kilograms of silver and 46.2 kilograms of gold. The average
diluted head grade was 1.5% copper.
The Alwin Project hosts a current inferred mineral resource comprising 1.46 million tonnes (Mt)
tonnes, at an average grade of 1.08% Cu, yielding 34.6 million pounds of Cu4.
The Alwin Project is adjacent with the western boundary of Teck Resources’ Highland Valley Mine,
the largest open -pit porphyry copper -molybdenum mine in western Canada. Alteration and
mineralization of the Highland Valley hydrothermal system extends westward from the Highland
Valley mine onto the Alwin Project (see GSP’s news release dated January 30, 2020).
