Adventus mining and Salazar resources secure us$235.5 Million with Wheaton Precious Metals and Trafigura to construct the Curipamba copper project

Adventus Mining Corporation (“Adventus Mining”) (TSX-V: ADZN; OTCQX: ADVZF) and Salazar Resources Limited ("Salazar") (TSX-V: 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. ( “Wheaton”) in respect of the Curipamba copper project in central Ecuador (the “Curipamba Project”). Additionally, Adventus Mining has entered into a binding engagement for an Offtake Financing Agreement (the “OFA”) with Trafigura Pte Ltd (“Trafigura”) in respect of the Curipamba Project. A detailed feasibility study on the Curipamba Project, which focuses on the development of the shallow and high-grade El Domo deposit, was completed in late 2021 (the “Feasibility Study”). This significant financial commitment validates the Feasibility Study and economic potential of the Curipamba Project for all stakeholders and allows Adventus Mining and Salazar to firmly advance towards potential production.

Highlights

– Adventus Mining and Salazar have secured a total of US$235.5 million to advance and, following a construction decision, build the Curipamba Project, US$23.5 million of which will be available for pre-construction activities

– Financial arrangement compares to an estimated capital cost of US$248 million outlined in the Feasibility Study

– US$180.5 million financial commitment from Wheaton

• US$175.5 million upfront cash consideration, with US$13 million early deposit for pre-construction activities, and US$500,000 for local community development initiatives as part of the Curipamba Project prior to production
• Remainder to be available in four (4) staged installments during future construction, subject to certain customary conditions precedent being satisfied
• PMPA provides certain gold and silver streaming rights to Wheaton over life-of-mine, but limited to volcanic massive sulphide deposits that can be milled within the proposed Feasibility Study process plant
• Wheaton also intends to provide up to US$5M in equity to Adventus Mining, subject to a maximum Wheaton ownership level below 10%

– US$55 million financial commitment from Trafigura

• US$45 million senior debt facility, including US$5 million early deposit for pre-construction activities (the “Facility”)
• Remainder to be available in two (2) staged installments during future construction, subject to certain customary condition precedents being satisfied

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

• Wheaton will make ongoing payments for the gold and silver ounces delivered equal to 18% of the spot prices (“Production Payment”) until the value of gold and silver delivered less the Production Payment is equal to the upfront consideration of US$175.5 million, at which point the Production Payment will increase to 22% of the spot prices
• Prior to the official start of construction, AMI has a one-time option to repurchase 33% of the stream (gold and silver) on a change of control event for Adventus Mining, for an amount ensuring a fixed internal rate of return to Wheaton
• As is customary for Wheaton streaming arrangements, additional ESG support will be available from Wheaton while Curipamba is in production
• Adventus Mining and certain subsidiaries, which are the majority owners of the Curipamba Project, will provide Wheaton with corporate guarantees, pledges, and other security over their assets
