The Government of Ecuador Commits to Complete an Investment Protection Agreement

for the Curipamba - El Domo Copper-Gold Project

Toronto, June 13, 2022 – Adventus Mining Corporation (“Adventus Mining”) (TSX-V: ADZN, OTCQX: ADVZF) and Salazar

Resources Limited (“Salazar”) (TSXV: SRL) (OTCQX: SRLZF) (collectively the “Participants”) are pleased to announce a

preliminary commitment between the Ministry of Production, Foreign Trade, Investments and Fisheries and Adventus

Mining and Salazar with regard to an Investment Protection Agreement ("IPA") for the Curipamba - El Domo copper-gold

project in Ecuador (the “Project”). Adventus Mining and Salazar have been advancing discussions with the Government of

Ecuador on the terms and conditions of the IPA since the start of 2022.

The application submitted to the Ministry of Production, Foreign Trade, Investments and Fisheries of Ecuador in March

2022, includes a commitment to invest a total of approximately US$270 million over the next 12 years at the Project,

which is located in the canton of Las Naves, Bolivar Province. This future investment is in addition to the historical

investment of approximately US$50 million by the Participants up to the end of 2021. In return for the investment,

Adventus Mining and Salazar are negotiating government guarantees on security of title and investment, reduced tax

burdens on both income taxes and the capital outflow taxes, guarantees on infrastructure development, among other

items, which are customary features in similar agreements the government has established on other major Ecuadorian

mining projects.

Adventus Mining’s President and Chief Executive Officer, Christian Kargl-Simard, stated: "The IPA commitment declaration

by the Government of Ecuador is another significant milestone in the development of the Curipamba-El Domo Project.

Adventus Mining and Salazar continue to transparently earn the support and cooperation of the national Government of

Ecuador, local government representatives and project communities to realize the Project’s benefits for all stakeholders."
