GSP Resource completes geophysical survey at Alwin

Executive Summary

• GSP Resource Corp. released preliminary results of a 2025 NSAMT (natural‑source audio‑frequency magneto‑telluric) survey at the Alwin mine property, identifying a deep conductive anomaly that may indicate undiscovered porphyry‑style copper‑gold‑silver mineralization.
• The anomaly lies ~1.5 km northwest of the existing Alwin deposit, extends from 600 m to 1,200 m depth, measures roughly 600 × 750 m, and shows resistivity of 500–1,000 Ω·m.
• Historic drilling near the anomaly returned a notable intercept (9.7 m @ 0.55% Cu) but no follow‑up work has been done; the new geophysical target suggests significant upside potential for the project.

Key Details

• Survey Scope: 10 east‑west‑oriented lines covering ~15 line‑km across the Alwin property – first property‑wide survey in nearly 20 years.
• Conductive Anomaly Characteristics:
• Location: 1.5 km NW of the Alwin deposit (which hosts a 34.6 M lb inferred Cu resource).
• Depth: 600 m to 1,200 m.
• Size: ~600 m × 750 m.
• Resistivity: 500–1,000 Ω·m, consistent with quartz‑sericite altered porphyry bodies (similar to Endako district).
• Geological Significance: Anomaly aligns with a northwest‑trending sodic‑calcic fluid pathway linking GSP’s Mer property and HVC’s Bethsaida, Lornex, and Highmont deposits over >20 km.
• Historical Drilling Context:
• Hole 08‑06 (2008) – 9.7 m @ 0.55% Cu, strong porphyry‑style alteration and chalcopyrite‑bornite veins, located immediately south of the anomaly.
• Two shallow 1969 holes above the anomaly returned no significant mineralization but noted soft hematite/talc‑kaolinite gouge zones in Bethsaida granodiorite host rocks.
• Previous Geophysical Work: 2007 3‑D IP/Res surveys showed higher resistivity and weak chargeability at the deposit; a near‑surface conductive anomaly to ~200 m depth was also identified in the northern area.
• CEO Comment (Simon Dyakowski): Emphasized that the deeper conductive anomaly reinforces the hypothesis of a porphyry source for Alwin’s high‑grade Cu‑Ag‑Au mineralization and highlights exploration upside along the regional fluid pathway.
• Qualified Person: Kristopher J. Raffle, P.Geo (B.C.), principal/consultant of APEX Geoscience Ltd., reviewed and approved the technical information per NI 43‑101.

Notable Quotes

“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… further reinforces our view of the compelling exploration upside at Alwin.” – Simon Dyakowski, CEO, GSP Resource Corp.
