RPX Gold Expands Gold Mineralization Beyond the PEA Open Pit and Underground Mine in Support of the Planned PFS

RPX Gold Inc. (RPX) has reported assay results from 25 diamond drill holes, totaling 4,336 meters, at its Wawa Gold Project in Ontario. The company stated that the release is not a new discovery but rather reports resource-conversion, infill, and step-out drilling designed to support a planned Prefeasibility Study and an updated resource estimate.

Key new intercepts highlighted in the release include:

• SD-26-676: 1.87 g/t Au over 35.10 m, including 21.50 g/t Au over 1.00 m and 6.22 g/t Au over 2.35 m.
• SD-26-674: 1.19 g/t Au over 33.98 m, including 10.00 g/t Au over 0.98 m and 5.77 g/t Au over 1.07 m.
• SD-26-677: 1.68 g/t Au over 16.68 m, including 5.16 g/t Au over 1.19 m and 8.46 g/t Au over 1.16 m.
• SD-26-675: 2.66 g/t Au over 9.87 m, including 7.02 g/t Au over 2.69 m.
• SD-26-660A: 2.05 g/t Au over 4.26 m and 4.68 g/t Au over 2.35 m.
• SD-26-685: 1.61 g/t Au over 8.47 m, including 11.50 g/t Au over 0.71 m.

The release also repeats older post-PEA intercepts, such as SD-26-626, SD-25-616, SD-26-639, SD-25-593, SD-26-627, and SD-26-636, to support the potential North-South pit connection narrative. RPX Gold stated that roughly two-thirds of the PFS-focused drilling meterage and half of the 20,000-meter 2026 program is complete. All 25 holes are reported in Table 2, including lower-grade intervals and narrow intercepts.

RPX Gold Inc. (RPX) is advancing its project through an advanced stage, supported by a Preliminary Economic Assessment (PEA) and a current mineral resource estimate comprising 1.244 million ounces indicated and 509,000 ounces inferred. Recent drilling efforts have focused primarily on resource conversion and geotechnical support for a Preliminary Feasibility Study (PFS).

New drill holes have extended mineralization beyond the PEA mine plan at grades around or above the open-pit resource grade, particularly in the southern Old Tom Upper area. However, these results do not constitute a discovery or a transformational event. The best new intercept recorded 1.87 g/t over 35.10 m, a result considered good but not exceptional for this deposit type, with grade-thickness metrics well below those of several previously announced holes.

The stock is trading at C$0.16, near the lower end of its 52-week range. The market has not re-rated upward on previous stronger drill results; the May 27, 2026 release containing the higher-grade SD-26-626 and SD-26-639 holes did not produce a lasting rally. This current release does not clear a highly embedded performance bar. It remains consistent with the existing thesis that Wawa can grow its open-pit resource and move toward a PFS, but it does not materially de-risk or expand the project on its own.

Expected share-price impact is likely muted, with no obvious catalyst for a 15%+ move.

RPX Gold Inc. is a Canadian gold exploration and development company focused on the 100%-owned Wawa Gold Project in the Michipicoten Greenstone Belt of northwestern Ontario. The property covers over 7,000 hectares and is located near the town of Wawa, benefiting from established infrastructure and access to regional mills.

Current resource estimates for the project include an Indicated category of 22.909 Mt at 1.69 g/t Au, containing 1,244,000 oz Au, and an Inferred category of 9.951 Mt at 1.59 g/t Au, containing 509,000 oz Au.

A preliminary economic assessment (PEA) at a US$3,500/oz gold price highlights the following metrics: * After-tax NPV5% of C$523 M. * After-tax IRR of 99.7%. * Initial capital of approximately C$51 M. * Payback of less than one year. * Average annual production of approximately 66 koz over a nine-year life.

The development strategy outlines phased open-pit mining followed by underground mining, utilizing toll milling rather than an on-site mill. The company’s capital structure includes 445.0 M basic shares outstanding and 530.3 M fully diluted shares outstanding. Alamos Gold owns approximately 8.9% of the company. No production decision has been made, and the project remains pre-revenue.
