Novo Mundo Project Development History

Article content

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.

Article content

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.
