Red Pine Extends Significant Mineralization West of the Jubilee Shear – drills 5.10 g/t gold over 19.76 metres within 1.94 g/t gold over 78.9 metres

TORONTO, Sept. 21, 2023 - Red Pine Exploration Inc. (TSXV: RPX, OTCQB: RDEXF) ("Red Pine" or the "Company") is pleased to report new drilling results from its ongoing exploration program. The new results extend gold mineralization of significance in the footwall of the Jubilee Shear as a direct follow-up on hole SD-23-430 that intersected 1.33 g/t gold over 100.99 metres.

• Testing of the Wawa Gold Corridor west of the Jubilee Shear (Figures 1 and 2)
  • 5.10 g/t gold over 19.76 metres within 1.94 g/t gold over 78.9 metres in the Core Shack Vein Network in SD-23-446
  • Close-to-surface high-grade gold mineralization intersected in both SD-23-430 and SD-23-446 is associated with the Core Shack Vein Network
  • The Core Shack Vein Network is comprised of multi-directional and extensional quartz-tourmaline veins emplaced in the intrusive rocks of the Jubilee Stock
  • The veins post-date the intense event of tectonic deformation associated with the formation of the Jubilee Shear
    

Quentin Yarie, President and CEO of Red Pine Exploration commented: "The footprint of a new resource contained within a shallow optimized open pit and encompassing our existing resource continues to take shape. Long intersections of gold in the hanging and footwall will substantially affect a strip ratio in a positive direction. We currently have two drills on the property producing over 4000m of core per month which is exceeding our planned drill production. We currently have over 2600 assays pending."

Assay results presented over core length. True width for the different veins intersected in both vein networks is estimated to vary between 35 to 95% depending on the angle of the intersected vein. The larger envelope of the vein network is discordant to the angle of the individual veins forming the networks.

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

Drill core samples were transported in security sealed bags for analyses to Actlabs in Ancaster, Ontario. Individual samples were labelled, placed in plastic sample bags and sealed. Groups of samples were then placed into durable rice bags and shipped. The residual coarse reject portions of the samples remain in storage if further work or verification is needed.

Red Pine has implemented a quality-control program to comply with best practices in the sampling and analysis of drill core. As part of its QA/QC program, Red Pine inserts external gold standards (low to high grade) and blanks every 20 samples in addition to random standards, blanks, and duplicates.

Forward-looking information contained in this news release includes but may not be limited to: "the potential for a hybrid pit and underground project." Investors are cautioned that forward-looking information is not based on historical facts but instead reflect management's expectations, estimates or projections concerning future results or events based on the opinions, assumptions and estimates of management considered reasonable at the date the statements are made. Such opinions, assumptions and estimates are inherently subject to a variety of risks and uncertainties that could cause actual events or results to differ materially from those projected and undue reliance should not be placed on such information, as unknown or unpredictable factors could have material adverse effects on future results, performance or achievements.
