TORONTO - Adventus Mining Corporation ('Adventus') (TSXV: ADZN) (OTCQX: ADVZF) and Salazar Resources Limited are pleased to announce that the Environmental and Social Impact Assessment ('ESIA') for the Curipamba copper-gold project located in central Ecuador has been completed and the environmental licensing process has been initiated with the Ecuadorian Ministry of Water, Environment and Ecological Transition (the 'Ministry').

The completed ESIA is the culmination of over two years of environmental, community, and engineering activities led by the Partners, with the assistance of several internationally recognized and Ecuador-experienced consulting firms. Importantly, the ESIA includes all technical design and project scope parameters detailed in the recently completed Curipamba feasibility study. The Partners expect to work closely with the Ministry during the ESIA review period as approval is required for the construction decision on the Curipamba project.

President and CEO of Adventus, Christian Kargl-Simard stated: 'After completing thorough baseline studies, we are very pleased to announce the completion of the Curipamba ESIA and the start of the environmental licensing process. Officially starting the ESIA review process is a key milestone in our goal of having Curipamba as the next mine built in Ecuador. This has been a collaborative effort between the Partners and our team of internationally and locally recognized consultants. We have also been working very closely with the government to ensure our design complies with all Ecuadorian standards and regulations. We look forward to continued collaboration with the appropriate government ministries as we go through the permitting and approval process and advance the Curipamba project towards future operations.'

President and CEO of Salazar, Fredy Salazar stated: 'We have been working in the Curipamba district for over ten years and are excited to see the project moving to this next stage of development. This is an excellent project, and we are proud to formalise the great work that has been done in environmental management and community relations. We look forward to working with government authorities and local stakeholders in the next phase of the ESIA review to ensure the highest standard of environmental protection and that community benefits are maximized.'
