Constitutional Court of Ecuador Issues Ruling on Constitutionality of Environmental Consultation Decree:

Leaving the Decree and Consultation Process in Effect Pending Law from National Assembly

Toronto, November 17, 2023 – Adventus Mining Corporation (“Adventus”) (TSX-V: ADZN, OTCQX: ADVZF) and Salazar

Resources Limited (“Salazar”) (TSX-V: SRL, OTCQB: SRLZF) (collectively the “Participants”) are pleased to announce that

the Constitutional Court of Ecuador ( the “Court”) has issued a ruling with regards to the constitutionality of Presidential

Decree 754 (the “Decree”). The Decree, signed in May 2023, modified the Environmental Regulation of the Environmental

Organic Code to include detailed steps for carrying out the Environmental Consultation (the “Consultation”) in accordance

with international human rights instruments and guaranteed by article 398 of the Ecuadorian Constitution.

The Consultation is a prerequisite for the issuance of environmental licenses for all projects across all sectors in Ecuador

(not limited to the metals and mining sector) classified as medium and high impact, but also those classified as low impact

for the extractive industries. The Consultation seeks to ensure people in the impact areas are duly informed and consulted

with regards to impacts, mitigations, and environmental management plans of the proposed projects.

The Decree was challenged by an Act of Unconstitutionality filed with the Court in June 2023 and accepted by the Court

in August 2023 along with a precautionary measure that ordered the provisional suspension until the Court could resolve

the case (see news release dated August 2, 2023) . In September 2023, the Court prioritized the case (see news release

dated September 11, 2023) and the hearing was held on September 18, 2023. On November 17, 2023, the Court issued

its ruling that declared Decree 754 to be unconstitutional in form , and indicated that the Consultation process must be

regulated through an organic law which can only be issued by the National Assembly of Ecuador (the “Assembly”) and not

by Presidential decree. Notwithstanding, the ruling defers the effects of the unconstitutionality decision until the Assembly

passes an organic law to regulate the Consultation process. The ruling also expressly revokes the temporary suspension

of the Decree and indicates that the Decree will remain in-effect until the Assembly passes a new law regulating the

Consultation.

This decision by the Court allows over 170 projects to resume their respective Consultation processes by proceeding under

the terms the Decree. These important projects span across all industries and sectors in Ecuador, which include but are

not limited to hospitals, water treatment plants, roads, clean energy projects, and three mining related projects, including

the El Domo -Curipamba project. Therefore, the Participants are pleased to continue the advancement of the El Domo -

Curipamba project in line with recent guidance.
