FINAL STAGE OF THE ENVIRONMENTAL CONSULTATION PROCESS FOR THE EL DOMO - CURIPAMBA PROJECT HAS BEEN COMPLETED - CLEARING THE WAY FOR ISSUANCE OF THE ENVIRONMENTAL LICENSE

The Ministry of Environment, Water and Ecological Transition of Ecuador (MAATE) has completed the final consultation phase of the environmental consultation process for Adventus Mining Corp. and Salazar Resources Ltd.'s El Domo/Curipamba project in central Ecuador on Dec. 15, 2023.

The final consultation phase was carried out by MAATE in accordance with instructions and guidelines given by the Constitutional Court in Ruling 51-23-IN/23, published on Nov. 17, 2023. Six consultation assemblies, open to the public, were held in the canton of Las Naves in both the direct and indirect areas of influence of the project. As part of the process, MAATE presented changes and inclusions to the project environmental management plan and environmental impact assessment based on community observations and feedback collected during the 14-day information phase carried out by MAATE in July, 2023. Following the presentation of the updated environmental management plan, the community participants deliberated and then voted with 98 per cent of people from the direct areas of influence of the project voting in favour of issuing the environmental licence for the project.

This positive outcome is a testament to the many years that the participants have worked closely and transparently with local stakeholders to maintain and build the project's social licence to operate. This result now clears the way for the expected issuance of the environmental licence for the project. The participants are pleased to continue the advancement of the project in line with recent guidance.
