CONSTITUTIONAL COURT OF ECUADOR PRIORITIZES THE ENVIRONMENTAL CONSULTATION PROCESS WRIT

Adventus Mining Corp. and Salazar Resources Ltd. (collectively, the participants) have provided an update from the writ issued by the Constitutional Court of Ecuador, which follows the news release from Aug. 2, 2023. On Aug. 1, 2023, the court admitted for processing an unconstitutionality claim filed by the indigenous group CONAIE (Confederation of Indigenous Nationalities of Ecuador) and other complainants against Presidential Decree 754 which regulates the environmental consultation process. All environmental consultation processes across all public and private sectors were suspended and were to await resolution of the matter by the court, including the participants' El Domo-Curipamba project.

On Sept. 7, 2023, in a follow-on writ, the court declared the process as priority and set a public hearing for Sept. 18, 2023. Historically, the court can be expected to issue a resolution within two to three months following the public hearing commencement. Such ruling is expected to provide clarifications to the decree and corresponding final step in the El Domo environmental consultation process.

The ruling is expected to give a clear path forward for the El Domo environmental licence. Once the environmental consultation process is restarted, the timing for final environmental and social impact assessment approval for El Domo could be as short as two months, with construction activities commencing shortly thereafter. In light of this update, the participants have updated execution plans for the potential start of construction activities in the second quarter of 2024. Working closely with El Domo stakeholders, the participants continue to advance and finalize detailed engineering, secondary permits as well as a financial investment through strategic discussions with third parties.
