Adventus Mining And Salazar Resources Secure Us$235.5 Million With Wheaton Precious Metals And Trafigura To Construct The Curipamba Copper Project

TORONTO, Jan. 17, 2022 - 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 Alliance Metals International ("AMI"), a wholly-owned subsidiary of the Participants' joint venture company Salazar Holdings Ltd., has, together with Adventus Mining, entered into a definitive Precious Metals Purchase Agreement (the "PMPA") with Wheaton Precious Metals International Ltd., a wholly-owned subsidiary of Wheaton Precious Metals Corp.

President & CEO of Adventus Mining Christian Kargl-Simard stated:

"This financial commitment is a major milestone for the Adventus Mining and Salazar and secures our ability to further optimize and begin construction of the Curipamba Project. Furthermore, the competitive structures of the financial arrangements serve to protect and benefit the interests of our investors and commercial partners. Based on the projected revenues payable to Wheaton, the potential read-through value of Curipamba is significantly higher than US$1 billion. We want to thank both the Wheaton and Trafigura teams who worked closely with us in conjunction with the completions of the Curipamba feasibility study and ESIA report in 2021. Special appreciation to the Wheaton team who have consistently showed their confidence and support for Adventus Mining since their equity investment in 2018.

To our partners and many stakeholders in Ecuador, Adventus Mining and Salazar are pleased to secure these significant long-term commitments from two of the largest and most respected metals and mining groups globally, which highlight both the confidence in the Curipamba Project becoming one of the next modern copper mines and in the growing responsible mining sector of Ecuador."

Streaming Arrangement with Wheaton - US$180.5 million

Pursuant to the PMPA, Wheaton will pay AMI a total upfront cash consideration of US$175.5 million, US$13 million of which can be paid on an early deposit basis to be used for pre-construction activities at the Curipamba Project and US$500,000 of which will be used to support certain local development initiatives in the Curipamba Project communities in the environmental, social and governance (ESG) areas. The remainder of the upfront cash consideration is payable in four staged installments during future construction of the Curipamba Project, subject to certain customary conditions precedent being satisfied.

Additional PMPA Transaction Details
