Red Pine Exploration Inc. (TSX-V: RPX) (OTCQB: RDEXF) 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)

• 9.03 grams per tonne gold over 14.00 metres core length, including 54.40 g/t Au over 2.00 m in hole SD-25-581
• 2.66 g/t Au over 10.13 m including 9.18 g/t Au over 1.12 m and 6.85 g/t Au over 1.00 m in hole SD-25-570
• 2.47 g/t Au over 7.50 m including 12.90 g/t gold over 0.73 m in hole SD-25-576.
• 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-25-520
  • 65.60 g/t Au over 1.12 m in hole SD-25-521

Michael Michaud, President and CEO of Red Pine commented: “We are encouraged by the near-surface drilling results, which returned high-grade gold within the Jubilee Shear Zone and confirms continuity with previous drilling. The presence of higher-grade mineralization near surface supports the potential for toll milling and use of regional infrastructure in our evaluation of the open pit potential of the Wawa Gold Project.

Our immediate focus is updating the mineral resource estimate ahead of a PEA in early 2026, which will define the optimal mining and processing strategy. With baseline studies underway and funding in place to complete the PEA, we are advancing toward production and the long-term goal of transitioning from explorer to producer in today’s strong gold price environment.”

Drilling Program

Red Pine has now completed its diamond drilling program that commenced in November 2024 and totaling 69 drill holes for 24,575 m. A total of 23 drill holes totalling 4,492 m of drilling are included in this release. The gold assay results from the drilling program will strengthen the geological database for the forthcoming update of the mineral resource that will support the evaluation of a possible open pit (Figure 1). Drilling has successfully demonstrated the presence of significant gold mineralization in the potential open pit area. Additional drilling results from 11 holes remain pending.

Drilling has also intersected gold mineralization in satellite zones in the hanging wall of the Jubilee Shear that could contribute to reducing the stripping ratio of the possible open pit and include the following significant results:

• SD-25-590 intersected 4.38 m @ 4.64 g/t Au, including 1.00 m @ 18.60 g/t Au
• SD-25-588 intersected 7.73 m @ 1.62 g/t Au, including 1.43 m @ 6.07 g/t Au

*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 Measures

Individual drill core samples are labelled and split in half along a pre-marked cutting line using a diamond saw. A consistent half-core sample is then placed in an individual plastic sample bag that is sealed. The remaining half-core samples are kept at the core storage facility of the Company 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 using a commercial carrier for analysis to Actlabs in Ancaster, Ontario. NQ core assays were obtained by 50-gram fire-assaying-AA finish or by 1-kilogram screen fire assay. The 1-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 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 insert 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.
