GSP Commences Field Investigations to Advance Alwin Mine and Mer Property Porphyry Targets

GSP Commences Field Investigations to Advance Alwin Mine and

Mer Property Porphyry Targets

News Release - Vancouver, British Columbia – September 16, 2025: GSP Resource Corp. (TSX-

V: GSPR / FSE: 0YD / OTC: GSRCF) (the “Company” or “GSP”) announces the mobilization of

field crews to the Alwin Mine and Mer properties to follow -up on recent ly identified geophysical

anomalies that are consistent with a potential porphyry mineralization source.

The fall 2025 Alwin- Mer surface exploration program is designed to follow -up on current

geophysical, regional porphyry footprint alteration mapping, and historic drilling within the

underexplored area north of the Alwin Mine. The 2025 exploration will be comprised of rock

geochemical sampling and reconnaissance geologic alteration mapping within the norther n Alwin

and Mer claims to aid in the development of future drill targets. In addition, at the Mer Property a

soil geochemical grid will be completed over the historic drilling and trenching area to better define

the potential footprint of copper-molybdenum mineralization (Figure 1).

The Company recently announced the results of a NSAMT (natural -source audio- frequency

magneto-telluric) geophysical survey at the Alwin Mine Property, which defined a conductive

anomaly at depth within the northern Alwin claims. The conductive anomaly occurs within a well-

defined northwest trending porphyry associated alteration zone extending northwest to the

Company’s Mer Property1 (see GSP Resource Corp. news release dated Agut 12, 2025).

Historic drilling within the northern Alwin claims near the conductive anomaly yielded zones of

porphyry-style copper mineralization returning 9.7 metres grading 0.55% copper within drill hole

08-062, with further drilling dating back to 1969 intersecting likely conductive talc-kaolinite altered

Bethsaida phase intrusive rocks.

Within the Mer Property, which is located 2.5 km to the northwest of the Alwin Property, the

Company has submitted a 5- year multi-year area based (MYAB) permit application to the British

Columbia Ministry of Mining and Critical Metals (“BC MMCM”) . The permit application was

submitted in preparation for an initial phase 1 drill program designed to follow up on a porphyry

copper-molybdenum zone defined by historic percussion drilling that returned mineralized intercepts

including 0.53% copper over 30 metres ( see GSP Resource Corp. news release dated March 13,

2025).

Forward-Looking Information

This news release contains “forward‐looking information or statements” within the meaning of applicable securities laws,

which may include, without limitation, completing ongoing and planned work, advancing the Alwin and Mer Properties,

the potential presence of mineralization at the Alwin and Mer Properties, further evaluation of mineralization at the Alwin

and Mer Properties, other statements relating to the technical, financial and business prospects of the Company, its

projects and other matters. All statements in this news release, other than statements of historical facts, that address events

or developments that the Company expects to occur, are forward- looking statements. Although the Company believes

the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are
