Adventus Mining and Salazar Resources Receive ESIA Technical Approval for the Curipamba-El Domo Copper-Gold Project in Ecuador

TORONTO, May 31, 2022 /CNW/ - Adventus Mining Corp. ("Adventus Mining") (TSXV: ADZN) (OTCQX: ADVZF) and Salazar Resources Ltd. ("Salazar") (TSXV: SRL) (OTCQX: SRLZF) (collectively the "Participants") are pleased to announce that the Curipamba-El Domo Project ("El Domo") has received technical approval of the Environmental and Social Impact Assessment ("ESIA") from the Ministry of Environment and Water of Ecuador ("MAATE"). In addition, the Ministry of Energy and Mines of Ecuador has issued the Certificate of Technical Feasibility for the construction of the El Domo tailings and waste rock facilities, which is a key requirement for the environmental licence from MAATE.

El Domo has been identified by the Government of Ecuador as a strategic project that will provide important economic investment opportunities for the country. Key benefits for Ecuador include the employment of a substantial construction workforce during the project development phase and approximately 400 permanent jobs during operations. An estimated total of US$376 million in taxes and royalties are expected to be paid to the government of Ecuador over the 10-year mine life outlined by the completed feasibility study on El Domo, which does not include the additional development of underground resources - see October 26, 2021, news release.

Adventus Mining and Salazar are committed to developing the next modern and responsible mine in Ecuador, with sustainability and community development in the foundation of our strategy. The technical approval of the ESIA is a significant milestone that allows El Domo to proceed to the Citizens Participation Process, final environmental licence issuance and formal construction decision expected in the second half of 2022.

Christian Kargl-Simard, President and CEO of Adventus Mining, stated: "We are very pleased by the continuing support from the Government of Ecuador and the achievement of this important milestone for the Curipamba-El Domo project. This ESIA technical approval is the culmination of approximately US$5 million of expenditures that funded a multi-year program of environmental and community work completed to industry best practice standards. Our team will continue active collaboration with government authorities and is excited to further advance this project into the next mine in Ecuador."

El Domo optimization and pre-construction activities remain on track towards a timeline of initial production in the second half of 2024. Detailed engineering is underway and is expected to continue into 2023, which will be sufficiently advanced to update capital cost estimates prior to the award of major contracts for construction. In June 2022, a previously planned supplemental geotechnical drilling program will commence to provide additional information to support the final engineering design. The project management team is actively engaged in prequalification discussions with potential mining contractors and also intends to purchase certified vendor data for long-lead process equipment during the third quarter of 2022. Pre-construction works on infrastructure upgrades is expected to commence in the fourth quarter of 2022, with full scale construction expected to commence in the second quarter of 2023.

Each RSU represents a right to receive one common share, following the vesting of such restricted share units following a two-year period. Adventus Mining has also granted an aggregate of 150,000 incentive stock options (the "Options") under its share compensation plan at an exercise price of C$0.63 per optioned share, exercisable for a period of five years from the date of grant and vesting over a three-year period.
