President of Ecuador Signs Pre-Legislative Consultation Decree: Confirming the Start of the Final Stage of El Domo ESIA Permitting

TORONTO, Nov. 30, 2022 - Adventus Mining Corp. ("Adventus Mining") (TSXV: ADZN) (OTCQX: ADVZF) and Salazar Resources Ltd. ("Salazar") (TSXV: SRL) (OTCQB: SRLZF) (collectively the "Participants") are pleased to announce that the President of Ecuador has signed the eagerly awaited pre-legislative consultation decree on November 28, 2022 ("Decree"). This Decree will guide the formal comment process for the draft environmental consultation regulation ("Regulation") as part of the Environmental and Social Impact Assessment ("ESIA") approval process. For the El Domo copper-gold project ("El Domo"), this Decree builds on the technical ESIA approval granted by the Government of Ecuador in May 2022 and the investment contract approved by the Government of Ecuador in November 2022 (see May 31 and November 10, 2022 Adventus Mining news releases).

Upon completion of the comment process for the Regulation, which is expected shortly, the President of Ecuador is expected to enact the Regulation through Presidential Decree. From there, the Participants expect two rounds of community consultations led by the Government of Ecuador. These community consultations are expected to be similar to the many community consultations led by the Participants since the discovery of the El Domo deposit within the Curipamba project concessions in 2008. Current guidance from the Government of Ecuador is that the Regulation comment period and subsequent final consultation process governed by the Regulation are expected to require seven to nine months to the signed and full approval of the El Domo ESIA, at which point full construction activities can begin.

During this period, the Participants are expected to finalize four other necessary permits for construction to begin, including: (a) Water No Affect Permit (for discharge and covering potential impact to any water sources), (b) Water Usage Permit (surface water capture during construction), (c) Tailings Infrastructure and Waste Storage Approval Permit (certificate of technical feasibility received), and (d) Explosives Permit. The permits have advanced well in 2022 with strong government engagement, which followed the publication of the El Domo feasibility study and submission of the ESIA report in December 2021.
