Resouro lodges Mining Concession Application for Novo Mundo Gold Project and Project Update

Key project development milestone achieved for ANM Process No. 866.035/2009 VANCOUVER, British Columbia, July 23, 2026 (GLOBE NEWSWIRE) -- Resouro Strategic Metals Inc. ( TSXV: RSM , ASX: RAU , OTCQB: RSGOF , FSE: 8TX ) ("Resouro" or the "Company") has marked a further step in the advancement of the Novo Mundo Gold Project (“Novo Mundo”) in Mato Grosso, Brazil. Its wholly owned Brazilian subsidiary, Ison do Brasil Mineração Ltda., successfully lodged the Mining Concession Application ( Requerimento de Lavra ) for ANM Process No. 866.035/2009 on 16 July 2026 . "Lodging of the Mining Concession Application is a key regulatory step toward converting our trial mining operation at Novo Mundo into a fully licensed, long-term producing asset,” said Christopher Eager, Resouro’s Chief Executive Officer. “It reflects the steady execution of our permitting strategy in the Alta Floresta Gold Province and moves us closer to establishing Novo Mundo as a sustainable cash generator for Resouro." The area covered by ANM Process No. 866.035/2009 comprises around 930 hectares and is the subject of a trial mining operation being conducted under a Guia de Utilização, pursuant to the previously announced Binding Mining and Processing Agreement for Novo Mundo.

The submission of the Mining Concession Application represents the next stage in the ANM licensing process for Novo Mundo, and once granted, will authorize long-term commercial mining of the area. It further strengthens Resouro's position as a growing gold developer with a meaningful presence in the highly prospective Alta Floresta Gold Province, one of Brazil's prolific gold-producing regions. This announcement has been authorized for release by the Board of Directors.

APPENDIX: Novo Mundo Project History and 2026 Technical Work Program The Novo Mundo Gold Project has been the subject of extensive historical exploration by Rio Tinto Zinco (RTZ), RJK Resources (RJK), Graben Mineraçäo (GMS), Nexa Resources (Nexa), and Resouro.

An Independent Technical Report prepared by GE21Consultoria Mineral (GE21) in support of the Company’s ASX listing concluded that the project hosts multiple porphyry–epithermal gold targets, supported by geological mapping, geochemistry, geophysics, trenching and diamond drilling. During 2026, Resouro substantially advanced exploration, permitting and trial mining activities, culminating in the submission of the Mining Concession Application. Major Historical Milestones 2026 Work Completed Comprehensive technical site review and stakeholder engagement.

Validation of Mineiro, Nivaldo, Modesto, and Raimunda targets. Two diamond drill holes were completed at Mineiro intersecting hydrothermal alteration and sulphides. Assay results are pending.

Drone surveys, orthophotography, and Real-Time Kinematic (RTK) surveys. Rock and channel sampling of historical workings. Recovery and re-logging of historical Nexa drill core.

Integration of historical exploration databases and target generation. Preparation of Final Exploration Reports for ANM. Trial mining and logistics testing under the Guia de Utilização.

Preparation and submission of the Mining Concession Application. Novo Mundo Project Development History Since acquiring the Novo Mundo Gold Project, Resouro has systematically advanced the Project through technical evaluation, permitting, and exploration programs aimed at progressing the Project toward production. The Project is supported by a substantial historical exploration database compiled by previous operators including RTZ, RJK, GMS, and Nexa, comprising geological mapping, geophysical surveys, geochemical sampling, and diamond drilling.

This historical work formed the basis of the Independent Technical Report prepared by GE21 to support the Company's ASX listing, which confirmed the Project's prospectivity and recommended further exploration to define JORC Mineral Resources and expand known mineralized systems. During 2026, Resouro significantly accelerated development activities. Following a comprehensive technical review and site visit in March 2026, the Company commenced an integrated exploration and development program including diamond drilling, UAV surveys, geological mapping, rock and channel sampling, re-logging historical drill core, integration of historical datasets, preparation of Final Exploration Reports, and advancement of trial mining under the existing Guia de Utilização.

Results from this program will be announced once assay data is received and verified by a Qualified Person. The Company also entered into a Binding Mining and Processing Agreement with Buriti Gold Mineração Ltda. and Future Mining Ltda., enabling the commencement of trial mining and bulk processing activities while progressing long-term permitting. This work culminated in the submission of the Mining Concession Application (Requerimento de Lavra) for ANM Process 866.035/2009, representing another significant milestone in the development of the Novo Mundo Gold Project.
