RED PINE UNCOVERS HIGH-GRADE GOLD IN COOPER AREA, HIGHLIGHTING SIGNIFICANT EXPLORATION POTENTIAL; PEA REMAINS ON SCHEDULE FOR H1 2026

Red Pine Exploration Inc. has released assay results from its Wawa gold project in Ontario. The new assay results are from two drill holes totalling 1,487 metres completed as part of the exploration drilling program finished in July, 2025. The holes were drilled to follow up on high-grade surface sampling results of 75.90 grams per tonne and 47.80 g/t gold (see Red Pine's press release dated Oct. 17, 2024). The results continue to outline the exploration potential of the Wawa gold project beyond the existing mineral resources that will be evaluated in the coming and fully financed preliminary economic assessment.

Highlights from drilling and surface exploration results in the Cooper area (Table 1):

• Discovery of 82.50 g/t Au over 0.74 metre in a quartz-tourmaline vein hosted in the Y106 shear in SD-25-556;
• Interpretations from surface observations and diamond drilling traced the Y106 shear over more than 500 m along strike and 320 m down-dip;
• Confirmation that the Jubilee shear extends 525 m north of the mineral resource;
• Confirmation that the gabbro dike observed at depth and interpreted to be associated with stronger gold mineralization in the Jubilee South area extends in the Cooper area (see press release of May 12, 2025).

Note: The reader is cautioned that grab samples are selective by nature and that the assay results from grab samples are not representative of the actual gold grade of the mineralized zones.

Michael Michaud, president and chief executive officer of Red Pine, commented: "The discovery of high-grade gold in the Cooper area underscores the strength of our exploration model and the untapped potential across the Wawa gold project. With the PEA targeted for completion in H1 2026, we are well positioned to demonstrate the full value of this emerging gold district."

Discussion of exploration results

The Cooper area hosts a network of at least seven extensional shear zones hosting gold-mineralized quartz veins that are oriented northwest to north-northwest and east-northeast. High-grade gold mineralization is present in the quartz veins hosted in each of the extensional shears. From west to east, the seven extensional shear zones identified in the Cooper area include: the Jasper, Bi-rich, Y106, Root, Cooper 11, Cooper and Ganley veins. Historical mining and underground development occurred in the Cooper vein (past-producing Cooper mine) and in the Jasper vein (capped inclined shaft). This network of extensional shears is emerging as a significant exploration target in the northern extension of the Wawa gold project. The northwest-oriented extensional shears are similar to the Minto mine shear hosting the Minto deposit. The new drilling intersections in the Y106 shear outline the potential of discovering new high-grade satellite deposits around the Jubilee deposit with additional exploration.

Quality assurance/quality control (QA/QC) measures

Individual drill core samples are labelled and sawn in half along a premarked cutting line. A consistent half-core sample is then placed in an individual numbered plastic sample bag that is sealed. The remaining half-core samples are kept at the company's core storage facility located on the Wawa gold project. Quarter-core duplicates are taken from certain samples to define the variability of gold distribution. Groups of samples are then placed into durable rice bags sealed with security seals to be transported by commercial carrier for analysis at Activation Laboratories Ltd. (Actlabs) in Ancaster, Ont. NQ core assays are obtained by 50-gram fire assay with an AA finish or by one-kilogram metallic screen fire assay. The one-kilogram metallic screen assay method is selected for samples anticipated to contain coarse gold and when the original fire assay returns results greater or equal to 2.25 g/t Au. The residual coarse reject portions of the samples remain in storage for a minimum 90-day period if further work or verification is needed.

As part of its QA/QC program, Red Pine inserts external gold standards (low grade to high grade) and blanks every 20 samples and routinely inserts blanks immediately after samples with visible gold. Quarter-core duplicates are routinely inserted to evaluate the natural variability of gold mineralization. Assay certificates are sent to at least three members of the senior management team, and they are directly accessible from the WebLIMS portal of Actlabs. Approximately 5 per cent of the pulps and coarse rejects analyzed at Actlabs are sent to Agat Laboratories in Thunder Bay for umpire testing.

Grab samples are transported in security-sealed bags for analysis to Actlabs in Ancaster, Ont. Individual samples are labelled, placed in plastic sample bags and sealed. Groups of samples are then placed into durable rice bags and shipped. Grab samples gold assays were obtained by 50-gram fire assaying (AA finish) or by one-kilogram screen fire assay. The one-kilogram screen assay method is selected for samples anticipated to contain coarse gold and when the fire assay (AA finish) return results greater or equal to 2.25 g/t gold. The residual coarse reject portions of the samples remain in storage for a minimum 90-day period if further work or verification is needed.

As part of its updated and independently reviewed QA/QC program, Red Pine inserts external gold standards (low grade to high grade) and blanks every 40 grab samples and routinely inserts blanks immediately after samples with visible gold. Assay certificates are sent to at least three members of the senior management team, and they are directly accessible from the WebLIMS portal of Actlabs.
