EL DOMO - CURIPAMBA PROJECT ACHIEVES MAJOR PERMITTING MILESTONE WITH APPROVAL OF THE TAILINGS STORAGE FACILITY

Adventus Mining Corp. and Salazar Resources Ltd. have learned that the Ministry of Energy and Mines of Ecuador (MEM), in conjunction with the Agency of Regulation and Control for Non-renewable Natural Resources of Ecuador, has issued a permit which grants approval for the design, construction, operation and maintenance of the tailings storage facility (TSF) for the El Domo-Curipamba copper-gold project located in central Ecuador. In conjunction with the recently granted environmental licence (see news release dated Jan. 22, 2024), this permit and approval allow the participants to further advance El Domo toward a construction decision expected in the first half of 2024. The start of TSF construction is a key condition precedent to draw from the financing package arranged with Wheaton Precious Metals Corp.

The permit application was submitted in June, 2023, in compliance with the requirements established in the MEM instructive for approval of tailings storage facilities for medium and large-scale mining projects. In addition to the detailed design and the risk management plan, the 1,300-page permit application contained 12 specific technical studies covering all aspects of the TSF design, construction, operations and maintenance. The application also includes certification of the stability analysis by a qualified third party expert.

In addition to complying with Ecuadorian regulations, the El Domo TSF design meets requirements of the Canadian Dam Association guidelines. The construction method will be downstream, using rock-fill which is the safest tailings dam configuration method. This major permitting milestone is a testament to Adventus and Salazar's continuing commitment to international best practices and to the highest technical standards of modern responsible mining.
