GSP Samples 87 g/t Silver, 3.3% Copper, & 2.3 g/t Gold, Demonstrating Multiple New Base and Precious Metals Targets Across the Combined Alwin Mine and Mer Properties

(TheNewswire)

Vancouver, British Columbia – TheNewswire - November 26, 2025: GSP Resource Corp. ( TSX-V: GSPR / FSE: 0YD / OTC: GSRCF ) (the“ Company ” or “ GSP ”) announces receipt of final assayresults from its recently completed Fall 2025 geologic reconnaissancetargeting program at the Mer Porphyry and Al conductor targets, inaddition to the newly discovered high-grade silver-copper Apex targetwithin the Alwin Mine Zone.  Assays for an additional 204 targetedgrid soil samples, as well as hyperspectral TerraSpec® analysis ofrock samples, are pending.

On October 28, 2025 the Company announced initial rushrock grab assay results that yielded high grade copper-silver plusgold; including 348grams-per-tonne (g/t) silver (Ag), 11.9% copper (Cu); and 104 g/t Ag,1.2 g/t gold, and 4.2% Cu from the Apex Zone. An additional 50 surface rock grab sample assays have been receivedwith highlights as follows (Figure 1, and Table 1):

• Apex Zone sample highlights including four additionalsamples returning 1.07 to 2.26 g/t Au; 33 to 83 g/t Ag; and 0.90 to3.3% Cu, respectively

• Mer Showing yields a broad 100 x 50 m area yielding 12samples returning between 0.14 to 1.02% Cu, and averaging 0.4%Cu

• Previously unsampled historic Mer Eastern Trenches,located 650 east of Mer Showing return bornite mineralized trenchfloat sample yielding 3.1% Cu, 12 g/t Ag

KeyTakeaways

• Assays from the Apex Zone cement this target as a highpriority for follow-up exploration and diamond drilling given itshigh-grade base-plus precious metal signature that bears similaritiesto the adjacent Alwin Mine.  Initial sampling in the Little OK Lakeand Area D zones both yielding multiple high grade copper valueshighlight a 1.5 km trend extending across the southern Alwin Property.

• The emerging MER Zone represents an attractiveearly-stage porphyry target that warrants modern diamond drilltesting.  Sampling has confirmed the presence of moderate coppergrades over a broad area.  Historic excavation accompanying ca.1970’s percussion and diamond drill testing was found to besurprisingly extensive.  The 2025 sampling serves to confirm thecompelling nature of the target based on the Company’s 3D modellingof historic drill intercepts ( see GSP Resource Corp. news release dated March 13, 2025 ).

Of the 60-surface rock grab sampled collect, a total of8 samples from the Apex showing returned greater than 1 g/t Au, and upto 2.26 g/t Au; a total of 11 samples returned greater than 10 g/t Agand up to 348 g/t Ag; and a total of 38 samples retuned greater than0.1% Cu and up to 11.85% Cu.

Methodology and QA/QC

The analytical work reported on herein was performed byALS Global (“ALS”), Vancouver, Canada. ALS is an ISO-IEC17025:2017 and ISO 9001:2015 accredited geoanalytical laboratory andis independent of GSP Resource Corp. and the QP. Rock samples weresubject to crushing at a minimum of 70% passing 2 mm, followed bypulverizing of a 250-gram split to 85% passing 75 microns. Base andprecious metals were determined via four-acid digestion 33 elementICP-AES geochemistry and overlimit values for copper (>1%) andsilver (100 g/t) were analyzed via four-acid digestion ICP-AES orAAS.

Rock grab samples are selective by nature and as suchare not necessarily representative of mineralization or grades acrossdefined intervals. Continued exploration including but not limited totrenching and/or diamond drilling will be required to confirm thegrade and continuity of mineralized zones.  GSP Resource Corp. hasrelied on the internal quality assurance/quality control (QA/QC)measure of ALS which includes the insertion of standard, blank andduplicate samples into the sample stream to confirm the accuracy ofthe reported results. GSP Resource Corp. detected no significant QA/QCissues during review of the data, and is not aware of any sampling, orother factors that could materially affect the accuracy of theresults.
