Red Pine Drilling Intersects 7.76 g/t Gold Over 15.49 m in Potential Open Pit Area & Commences Updated Independent Resource Estimate

Red Pine Exploration Inc. ( TSXV: RPX, OTCQB: RDEXF ) (" Red Pine " or the " Company ") is pleased to announce additional results from the recent near surface drilling program designed to better define gold mineralization in the area of a potential open pit at the Wawa Gold Project ( See Press Release dated May 8, 2025 ).

Drilling Highlights (Table 1 and Figure 1)

• 7.76 grams per tonne ("g/t") gold ("Au") over 15.49 metres ("m") core length, including 84.20 g/t Au over 1.00 m in hole SD-25-573
• 3.43 g/t Au over 9.63 m, including 9.77 g/t Au over 3.00 m in hole SD-25-574
• 5.37 g/t Au over 8.85 m, including 25.90 g/t gold over 1.03 m in hole SD-25-587
• 3.75 g/t Au over 7.63 m, including 8.95 g/t Au over 2.73 m in hole SD-25-589
• Previous intersections from the same area include:
  • 4.42 g/t Au over 18.99 m, including 40.20 g/t Au over 1.02 m in hole SD-17-172
  • 3.08 g/t Au over 16.72 m, including 40.20 g/t Au over 1.00 m in hole SD-24-520
  • 65.60 g/t Au over 1.12 m in hole SD-24-521
  • 9.03 g/t Au over 14.00 m, including 54.40 g/t Au over 2.00 m in hole SD-25-581

Michael Michaud, President and CEO of Red Pine commented: "We are excited by these near surface drill results that continue to identify higher grades within the Jubilee Shear Zone. With the drilling for the updated mineral resource estimate now completed, we are moving forward to completing a preliminary economic assessment (" PEA ") in the first half of 2026.

At the same time, metallurgical, geotechnical, and baseline work is underway to support permitting. Our next drill phase to further expand near-surface gold mineralization is set to begin shortly.

With funding in place to complete the PEA, we are on track in our work to unlock significant value as we advance toward production and transition from explorer to producer in today's strong gold price environment."

Drilling Program

Red Pine recently completed its diamond drilling program comprised of 69 drill holes for 24,531.19 m, that commenced in November 2024. A total of 14 drill holes aggregating to 2,533.10 m of drilling are included in this release (Figure 1). The Company has now received all of the gold assay results for an updated independent mineral resource estimate currently underway by WSP Canadal Inc. and to be disclosed in the pending PEA.

*Intercepts are calculated using a 0.40 g/t Au cut-off and a maximum of 6.0 m of internal dilution with no capping applied and are reported over core lengths. True widths are estimated to vary between 70 to 95% of the reported core length in the Jubilee Shear.

Quality Assurance/Quality Control ("QA/QC") Measures

Individual drill core samples are labelled and sawn in half along a pre-marked 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), Ancaster, Ontario. NQ core assays are obtained by 50-gram fire-assay with a AA finish or by 1-kilogram metallic screen fire assay. The 1-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- 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% of the pulps and coarse rejects analyzed at Actlabs are sent to Agat Laboratories in Thunder Bay for umpire testing.
