RPX GOLD PROVIDES CORPORATE UPDATE AND NEXT STEPS TO ADVANCE THE WAWA GOLD PROJECT TOWARDS A PRE-FEASIBILITY STUDY

RPX Gold Inc. has provided shareholders with a corporate update outlining the significant progress achieved since January, 2026, and our next steps toward preparation of a prefeasibility study (PFS) and the ultimate goal of gold production.

Recent highlights:

• Preliminary economic assessment (PEA) announced on Feb. 18, 2026, which disclosed an after-tax net present value (discounted at 5 per cent) of $523-million and an after-tax internal rate of return (IRR) of 99.7 per cent at a base-case gold price of $3,500 (U.S.) per ounce, with initial capital of $51-million and projected sub-one-year payback based on a toll milling scenario;
• Closed equity financing for gross proceeds of $14.1-million on May 13, 2026, providing capital to advance baseline studies, exploration drilling (including resource conversion drilling) and progress toward a PFS;
• Corporate name changed to RPX Gold Inc. to better reflect the company's focus on advancing the Wawa gold project;
• PFS completion targeted for first half of 2027, with clear milestones defined and underpinned by an updated resource estimate, toll milling, first nation and community engagement and alignment, and continuing environmental baseline programs;
• Broadened the management team to better advance environmental studies, permitting, first nations and community relations.

Michael Michaud, president and chief executive officer of RPX, commented: "The second quarter of 2026 has been transformative for our company. The PEA validated the Wawa gold project as a robust, capital-efficient project with a potential development opportunity with a low initial capital requirement and an exceptional return profile.

"Our focus now is to advance the PFS to completion, which is anticipated in early 2027. The activities to advance the PFS represents a derisking of the Wawa gold project, which we believe will add value at every step along the way.

"Further, with the financing now closed we have commenced exploration drilling to test the near-surface strike extension of the deposit between the two open pits. We also plan to test several of the exploration targets identified in the 2025 drilling program later in the program.

"All of the work planned for the remainder of 2026 will be funded from the use of proceeds from the recently completed financing."

Preliminary economic assessment

On Feb. 18, 2026, the company announced the results of an independent PEA for the 100-per-cent-owned Wawa gold project, located in Northwestern Ontario, Canada. The PEA was prepared by DRA Americas Inc. in accordance with National Instrument 43-101 and was supported by an updated 2026 mineral resource estimate (MRE) prepared by WSP Canada Inc., which reflected a 48-per-cent increase in indicated ounces compared with the 2024 MRE.

The PEA outlined a proposed phased, capital-efficient development plan beginning with open-pit mining of near-surface mineralization followed by a transition to underground mining, utilizing toll milling at regional facilities to eliminate the need for an on-site mill or tailings facility. Key financial highlights at the base-case gold price of $3,500 (U.S.) per ounce include:

1. After-tax NPV (discounted at 5 per cent) of $523-million and after-tax IRR of 99.7 per cent at a base-case gold price of $3,500 (U.S.) per ounce and an after-tax NPV (discounted at 5 per cent) of $935-million and an IRR of 181 per cent at a gold price of $4,500 (U.S.) per ounce;
2. Base-case average annual after-tax free cash flow (excluding initial capital expenditures) of $85-million and cumulative after-tax free cash flow of $767-million; first five years of production $354-million after-tax free cash flow (excluding initial capital expenditures);
3. Life-of-mine (LOM) cash costs of $1,835 (U.S.) per ounce and all-in sustaining costs (AISC) of $2,149 (U.S.) per ounce at the base-case gold price;
4. Initial capital: approximately $51-million;
5. Payback period: less than one year.

The PEA demonstrated that the Wawa gold project has the potential to be developed in a highly capital-efficient manner, leveraging existing regional infrastructure and excess mill capacity in the Wawa area. With 81 per cent of gold production sourced from indicated resources, the Wawa gold project is well positioned for further exploration drilling, including resource conversion drilling to advance the remaining inferred ounces ahead of a PFS.

Readers are cautioned that the PEA is preliminary in nature includes inferred mineral resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized. The preliminary economic assessment includes an assumption that toll milling will be utilized, which requires a third party agreement that has not been completed.

$14.1-million financing

On May 13, 2026, the company successfully closed an oversubscribed financing for gross proceeds of $14.1-million. The financing included a number of investments from new institutional investors as well as from existing shareholders.

Path to prefeasibility

The company is targeting the delivery of a PFS in the first half of 2027. The company anticipates that the PFS will build on the PEA foundation, incorporating an updated mineral resource to be completed following further exploration drilling, including infill drilling to be completed, additional metallurgical test work, detailed geotechnical assessments, toll milling discussions, and refined capital and operating cost estimates. There can be no assurances that these expectations will result from such additional activities.

The company's management has outlined the following near-term workstreams and milestones to be advanced with financing proceeds:

1. Environmental baseline studies:
   • The company will continue to complete multiseason environmental baseline data collection programs required to support future environmental assessments and permitting applications.
2. Resource conversion drilling:
   • The PEA mine plan identified that approximately 63 per cent of open-pit ounces and 86 per cent of underground ounces included in the economic model were classified as inferred mineral resources. A targeted exploration drill program, including an infill drill program, will be undertaken to, among other things, incorporate any new discoveries and to upgrade existing inferred mineral resources to the indicated mineral resource category.
   • As part of this work, the company recently completed approximately 10,000 metres of near-surface exploration drilling that was designed to better define and expand the deposit. The results of this drilling, which was not included in the PEA, will be released once received. Additional drilling is continuing.
3. Continued engagement with first nations:
   • RPX recognizes that strong, long-term relationships with indigenous communities are integral to advancing the Wawa gold project and delivering sustainable value to all stakeholders.
   • The company is committed to ongoing, transparent engagement throughout the life of the Wawa gold project and is actively working with first nations to complete environmental baseline studies. In parallel, RPX continues to advance constructive discussions toward benefit agreements, which are expected to support local participation and provide a clear framework for shared economic benefits.
   • The company is also continuing to strengthen its team in environmental, first nations and community relations, with the addition of Stephanie LaBelle of Civita Consulting as a community relations consultant with over a decade of experience in fostering relationships between communities and industry. Ms. LaBelle has been involved in recent impact and benefits agreements and managing consultation permitting requirements on brownfield and greenfield resource development projects in Ontario.
4. Toll milling memorandum of understanding:
   • The company has identified multiple potential toll milling facilities within trucking distance of the Wawa gold project that are capable of processing material on a conventional cyanidation basis, consistent with 2019 and 2025 metallurgical test work results. Discussions with these facilities are continuing, and any actual toll milling will be dependent on the results of further exploration activities noted above.

About RPX Gold Inc.

RPX Gold (formerly Red Pine Exploration Inc.) is a Toronto-based gold exploration company. The company's shares trade on the TSX Venture Exchange under the symbol RPX and on the OTCQB market under the symbol RDEXF.

The company's flagship asset, the Wawa gold project, is located in Northwestern Ontario, in the Michipicoten greenstone belt of Ontario, adjacent to several established gold-producing operations, including those operated by Wesdome Gold Mines Ltd., Alamos Gold Inc. and Hemlo Mining Corp. The Wawa gold project benefits from strong local infrastructure and excess regional mill capacity.

The company is evaluating open-pit operations initially that are designed to generate early cash flow to help finance advancement of the underground operation. This phased approach is aimed at derisking development, accelerating time to revenue and minimizing shareholder dilution. The approach is subject to the completion of a number of milestones before a production decision can be made, such as continued drilling and mineral resource definition, conducting additional metallurgical test work, completing a prefeasibility study, continuing baseline studies, as well as additional permitting and indigenous consultations, among other factors.

The Wawa gold project currently hosts mineral resources from two mineral deposits, namely the Jubilee shear and the Minto mine. The mineral resource includes an indicated mineral resource of 22,909,000 tonnes grading 1.69 grams per tonne gold containing 1,244,000 ounces gold and an inferred mineral resource of 9,951,000 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. Please refer to the technical report entitled "Preliminary Economic Assessment: Wawa Gold Project" with an effective date of Feb. 18, 2026, which is available on SEDAR+ under the company's profile, for more information.
