20,000 Metre Drill Program Ongoing to Support PFS to be Completed in H1 2027

TORONTO -- (Business Wire)

RPX Gold Inc. (“RPX Gold”, “RPX” or the “Company”) (TSXV: RPX. OTCQB: RDEXF) is pleased to announce the mobilization of a second diamond drill at its Wawa Gold Project in Ontario (Figure 1). The second drill will expedite the completion of the ongoing 20,000 metre (“m”) drilling program, of which approximately 5,000 metres have been completed to date, in preparation of a prefeasibility study (“PFS”) targeted for completion in the first half of 2027 (“H1 2027”).

Targeted areas in the new 2026 drilling program and drilling highlights from open-pit area drilling.

The 20,000 m drilling program aims to:

• Complete the conversion of inferred mineral resources to indicated mineral resources in strategic areas of the mine plan identified in the 2026 Preliminary Economic Assessment (“2026 PEA”);
• Acquire additional data for grade validation, and metallurgical and geotechnical purposes in key areas of the underground mine plan identified in the 2026 PEA; and
• Conduct initial follow-up drill testing of several exploration targets identified by previous drilling in areas outside of the current mineral resource.

Michael Michaud, President and CEO of RPX Gold, commented: “Mobilizing a second drill at Wawa is an important step in advancing the project toward a PFS early next year. With two rigs now active, we are well positioned to accelerate our fully-funded 20,000 m drill program and move efficiently toward an updated mineral resource estimate and PFS.

“Our immediate focus is completing the resource conversion drilling needed to upgrade areas of the mine plan that were classified as inferred resources in the 2026 PEA. The additional drill capacity allows us to advance the resource conversion in parallel with the metallurgical, geotechnical and grade validation required to support the PFS.

“The second drill will provide greater flexibility to test exploration targets identified through the 2025–2026 program, further highlighting the upside potential of the land package. This is a disciplined use of our drilling to compress timelines and advance technical workstreams in parallel, de-risking of the project at every stage. Our priority remains advancing the Wawa Gold Project toward completion of the PFS, targeted for H1 2027.”

2026 Drilling Program

The 2026 PEA mine plan identified that approximately 63% of open-pit ounces and 86% of underground ounces included in the economic model were classified as indicated mineral resources. On May 14, 2026, the Company announced results of an initial 9,000 m drilling program, targeting the conversion of inferred resources to the indicated confidence category in the areas of the Jubilee Deposit with open pit potential.

Highlights from the 9,000 m 2025-2026 Drilling Program Include (see press release of May 27, 2026 and December 16, 2025):

• 13.82 grams per tonne gold (“g/t Au”) over 4.94 metres (“m”), incl. 55.20 g/t Au over 1.04 m in SD-26 639;
• 23.20 g/t Au over 1.18 m and 2.09 g/t Au over 5.37 m, incl. 9.67 g/t Au over 0.78 m in SD-26-636;
• 8.77 g/t Au over 13.33 m, incl. 30.12 g/t Au over 3.39 m in SD-26-626;
• 3.33 g/t Au over 16.78 m, incl. 19.40 g/t Au over 0.97 m in SD-26-627;
• 2.38 g/t Au over 14.49 m, incl. 8.94 g/t Au over 1.31 m and 9.32 g/t Au over 0.88 m in SD-25-625
• 4.63 g/t Au over 13.25 m, incl. 18.60 g/t Au over 1.47 m and 14.70 g/t Au over 0.88 min SD-25-593 (see news release dated December 16, 2025).

Note: 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 50 to 95% of the reported core length in the Jubilee Shear.

RPX Gold has since initiated a new 20,000 m diamond drilling program focused on resource conversion within strategic areas of the underground mine plan as identified in the 2026 PEA, including 3,000 m to 5,000 m of grass roots exploration drilling. The Company is mobilizing a second drill rig to support the next phase of advancement which will include an updated mineral resource estimate to be utilized in the preparation of a PFS anticipated in H1 2027.

The resource conversion drilling to upgrade inferred mineral resources to the indicated mineral resource category will consist of 15,000 m to 17,000 m of drilling, and will allow for data collection of material for metallurgical, geotechnical and grade validation purposes to support the PFS.

This drilling program commenced in April, 2026, and as of July 12, 2026, the Company has completed approximately 5,000 m.

Appointment of Target IR & Communications

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, RPX Gold 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.

Qualified Person Jean-François Montreuil, P.Geo., Vice President, Exploration at RPX Gold, and a Qualified Person as defined under National Instrument 43-101, has reviewed and approved the scientific and technical information in this press release.
