GSP Plans Expanded Drill Campaign and Highlights Recent Exploration Success at the Combined Alwin-Mer Properties, Highland Valley Copper Camp, BC

(TheNewswire)

Vancouver, British Columbia – March31, 2026 – TheNewswire-  GSP Resource Corp. (TSX-V: GSPR / FSE: 0YD / OTC:GSRCF) (the “Company” or “GSP”) announces thesubmission of a new 5-year multi-year area based (MYAB) permitapplication to the British Columbia Ministry of Mining and CriticalMetals (“BC MMCM”) for the Alwin Mine Project.

The Alwin Mine Project is currently permitted fordrilling activities through an existing Mines Act Permit, and uponapproval the new permit will allow for expanded drill testing of newlyidentified exploration targets throughout the Property, in addition toalready permitted near-mine areas.

Throughout 2024 and 2025 the Company executedmulti-phased exploration campaigns including: surface rock and soilsampling; short wave infra-red (VIS-SWIR) hyperspectral TerraSpec®analysis; NSAMT (natural-source audio-frequency magneto-telluric)geophysical surveys; and diamond drilling.

The exploration campaigns identified opportunities toexpand existing mineral resources and resulted in the discovery of newpotential porphyry and high-grade copper-gold-silver vein targets. Highlights of the 2024 and 2025 Alwin Mine Project explorationinclude:

• Discovery of New High-Grade Gold Zone within drill holeAM-24-06 assaying 5.04 g/t Gold and 1.01% copper over 7.90m; including22.93 g/t Gold and 1.82% copper over 1.64 m1.  The results point to the presence of a unique high-gradegold subset of mineralization at Alwin that is not yet wellunderstood. 

• The results of the summer 2025 NSAMT survey identifiedan untested deep conductive anomaly within the northern portion of theAlwin Property.  The results could indicate a potential underlyingporphyry source for the high-grade copper-gold-silver mineralizationat Alwin2 

• Fall 2025 surface rock grab sample results highlightthe high-grade Apex Zone that yielded assays including 1.85% copper,348 g/t silver and 2.6 g/t gold; in addition to the MER Zone returningwidespread moderate copper values. TerraSpec® analysis of thesesamples yielded muscovite and chlorite compositions at MER indicativeof a high temperature proximal porphyry environment, and peripheralporphyry environment at Alwin supporting the potential for anundiscovered porphyry system3 

• Fall 2025 soil geochemical results expand surfacecopper zone at nearby Mer Property and highlight near surface in-pitresource expansion potential at Alwin Mine4
