News Release - Vancouver, British
Columbia – TheNewswire
- October 28, 2025:
 GSP Resource Corp. (TSX-V: GSPR / FSE: 0YD / OTC:
GSRCF) (the “Company” or “GSP”) announces
initial rush assay results from its recently completed Fall 2025
geologic reconnaissance targeting program at the Mer Porphyry and Al
conductor targets, in addition to the newly discovered high-grade
silver-copper Apex target within the Alwin Mine Zone (see GSP resources Corp. News release dated
September 16, 2025).

An initial 10 select surface rock grab sample were
submitted for rush assay with highlights of the initial samples as
follows (Figure 1, and Table1):

• 348 grams-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.
   
  

  
  

• Alwin Mine and nearby historic “Area D” trenches
  yielded high grade assays of 5.5% Cu and 35 g/t Ag, and 1.6% Cu in
  outcrop and trench float.   
  

  
  

• Little OK Lake float exposed in road cuts yields 2.58%
  Cu and 1.62% Cu. 
  

  
  

• Mer Porphyry Zone returned outcrop samples returning
  0.52% Cu and 0.33% Cu. 
  

  
  

Details of Current
Exploration

The 2025 Mer and Alwin Mine geologic reconnaissance
program comprised of the collection of 60 surface rock outcrop and
float samples as well as 204 targeted grid soil samples.  This
exploration program represents the first surface work to be conducted
on expansionary exploration targets outside the Alwin Mine resource
area since 2008.  Within the Alwin Property, there are numerous
historic trenching and drilling areas for which there are little to no
assay documentation available.  Much of the historic exploration at
Alwin occurred during the 1960’s, 70’s and 80’s.  Recently,
clear-cut logging and road construction has re-opened access to these
historic exploration sites.

Historic Data
Compilation Yields New Targets

Historic data compilation for the Mer porphyry and Apex
targets highlights the significant near mine exploration potential
that remains.

At Mer, ca. 1970’s diamond and percussion
drilling and extensive caterpillar trenching sites were re-located
(see GSP Resource Corp. news
release dated March 13, 2025) and an area of
malachite-chalcopyrite mineralized granodiorite was sampled, and a
detailed soil grid was established to expand the potential drilling
target (Image 1).

At the recently re-discovered Apex Zone, located 40
metres off a modern logging road, historic 1977 diamond drill logs
lacking assay records documented a 2.6 metre core-width
chlorite-sericite, pyrite chalcopyrite mineralized alteration zone
including a quartz-carbonate vein containing 6-10% chalcopyrite. The
trench zone targeted by the 1977 drilling was located with the aid of
historic geologic maps and modern satellite imagery (Image 2).

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.
