RPX Gold Inc. Accelerates Drilling At The Wawa Gold Project
RPX Gold Inc. mobilized a second diamond drill at its Wawa Gold Project in Ontario. The second drill will expedite the completion of the ongoing 20,000 metre drilling program, of which approximately 5,000 metres have been completed to date, in preparation of a prefeasibility study targeted for completion in the first half of 2027. The 20,000 metre 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, acquire additional data for grade validation, and metallurgical and geotechnical purposes in key areas of the underground mine plan identified in the 2026 Preliminary Economic Assessment, and conduct initial follow-up drill testing of several exploration targets identified by previous drilling in areas outside of the current mineral resource. The 2026 Preliminary Economic Assessment 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 metre 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 metre 2025-2026 drilling program include: 13.82 grams per tonne gold over 4.94 metres, including 55.20 grams per tonne gold over 1.04 metres in SD-26 639; 23.20 grams per tonne gold over 1.18 metres and 2.09 grams per tonne gold over 5.37 metres, including 9.67 grams per tonne gold over 0.78 metres in SD-26-636; 8.77 grams per tonne gold over 13.33 metres, including 30.12 grams per tonne gold over 3.39 metres in SD-26-626; 3.33 grams per tonne gold over 16.78 metres, including 19.40 grams per tonne gold over 0.97 metres in SD-26-627; 2.38 grams per tonne gold over 14.49 metres, including 8.94 grams per tonne gold over 1.31 metres and 9.32 grams per tonne gold over 0.88 metres in SD-25-625; 4.63 grams per tonne gold over 13.25 metres, including 18.60 grams per tonne gold over 1.47 metres and 14.70 grams per tonne gold over 0.88 metres in SD-25-593. Intercepts are calculated using a 0.40 grams per tonne gold cut-off and a maximum of 6.0 metres 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 metre diamond drilling program focused on resource conversion within strategic areas of the underground mine plan as identified in the 2026 Preliminary Economic Assessment, including 3,000 metres to 5,000 metres 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 prefeasibility study anticipated in the first half of 2027. The resource conversion drilling to upgrade inferred mineral resources to the indicated mineral resource category will consist of 15,000 metres to 17,000 metres of drilling, and will allow for data collection of material for metallurgical, geotechnical and grade validation purposes to support the prefeasibility study. This drilling program commenced in April, 2026, and as of July 12, 2026, the company has completed approximately 5,000 metres. 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., 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 grams per tonne 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 quality assurance/quality control 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 Activation Laboratories Ltd. Approximately 5% of the pulps and coarse rejects analyzed at Activation Laboratories Ltd. are sent to Agat Laboratories in Thunder Bay for umpire testing. The Wawa Gold Project currently hosts mineral resources from two mineral deposits, namely the Jubilee Shear and the Minto Mine. The mineral resources include an indicated mineral resource of 22.909 million tonnes grading 1.69 grams per tonne gold containing 1,244,000 ounces gold and an inferred mineral resource of 9.951 million tonnes grading 1.59 grams per tonne gold containing 509,000 ounces gold, with both open-pit and underground mining potential. Gold mineralization extends to surface on a historic mining property, which supports the company’s phased development strategy.
