JZR Gold assumes operatorship of Vila Nova Gold Project

JZR Gold Inc. Assumes Operatorship of the Vila Nova Gold Project, Advances Toward Full Plant Production Capacity

VANCOUVER, British Columbia, May 28, 2026 (GLOBE NEWSWIRE) -- JZR Gold Inc. (TSXV: JZR) (OTCPK: JZRIF) (the “Company” or “JZR”) is pleased to announce that it has entered into an agreement with ECO Mining Oil & Gas Drilling and Exploration Ltda. (“ECO”) to assume direct operatorship of the Vila Nova Gold Project (the “Vila Nova Project” or the “Project”) located in Amapá State, Brazil, effective immediately.

The assumption of operatorship represents a significant strategic event for JZR, as the Company will now be the operator of the Project in addition to a royalty holder. With this change, JZR will take direct responsibility for plant operations, staffing, and production performance at the fully permitted Vila Nova facility.

JZR acknowledges the substantial contributions of ECO in advancing the Vila Nova Project to its current stage. Under ECO’s operatorship, the processing plant was constructed and commissioned, and critical infrastructure, including berms, roads, and retention ponds were completed. ECO also led the process of securing the environmental permits and regulatory approvals necessary to support ongoing operations. The Company believes this foundation provides a clear path forward as the Project moves into the next phase of development.

Following the transition, JZR has commenced the hiring of qualified and experienced personnel to manage and operate the processing plant. The Company’s immediate operational objective is to achieve maximum plant capacity on a consistent and sustainable basis. Management believes that with the infrastructure and permitting framework in place, the primary focus is now on operational execution and performance optimization.

“Taking operatorship of Vila Nova is a defining step for JZR," said Robert Klenk, Chief Executive Officer of JZR Gold Inc. "ECO successfully advanced the Project through its critical early stages, including construction, permitting, and commissioning, and we are grateful for their work. Our focus now is clear: operate the plant efficiently, build a capable team, and establish steady production from an asset that is already permitted and built.”

The Company will provide further updates on staffing, operational progress, and plant performance as the transition advances.
