Adventus Mining and Salazar Engage Invert Inc. to Help Achieve a Net-Zero Carbon Footprint

and Optimize Climate Change Strategies for the Curipamba Copper-Gold Project in Ecuador

Toronto, March 23, 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 new

partnership with Invert Inc. (“Invert”) focused on developing a greener future for the Curipamba project and its

stakeholders in central Ecuador (“Curipamba”). Globally and not just in the Americas, Curipamba is one of the highest

grade and lowest capital intensity copper -gold projects and is also expect ed to have lowest-quartile greenhouse gas

(“GHG”) emissions intensity during future operations. The project’s carbon footprint is expected to directly benefit from

the planned connection to the national power grid, which is already 80% supplied by hydro-electric sources, and proximity

to deep water ports. Adventus Mining an d Salazar seek to build upon these strengths by developing a robust

decarbonization roadmap and climate change policy from active project to future operations.

The partnership will see Adventus Mining and Salazar, together with Invert, develop a pathway and set targets towards a

True Net Zero mining future – covering Scope 1, 2 and ultimately Scope 3 GHG emissions. The pathway will involve setting

GHG emissions reduction targets based on science-based methodologies. This partnership will build upon the robust ESG

program and environmental licensing process that are already underway at Curipamba. Key partnership deliverables are

expected to include:

• Emissions inventory and forecast, including life-of-mine model that will categorize scopes and activity types

• Identification and quantification of emissions reduction strategies, by review of relevant technologies, target

setting, and carbon risk management – including unique advantages and opportunities in Ecuador

• Incorporate recommended GHG reduction initiatives that are in alignment with corporate and project objectives

President & CEO of Adventus Mining, Christian Kargl-Simard stated: “Copper is an essential part of the green energy

transition and global decarbonization efforts. It is increasingly evident that as an aspiring producer, we have the

responsibility and opportunity to align the Curipamba project with Ecuador’s global climate change contributions. We are

pleased to partner with Invert on this endeavour and look forward to providing more detailed updates as this strategy is

developed and implemented.”

Andre Fernandez, Co -CEO of Invert stated: "Invert is thrilled to partner with Adventus Mining as a trusted partner to

achieve ambitious decarbonization targets that will make an impact to their stakeholders. We have deep technical

expertise in mining, decarbonization, and climate change strategy – all of which will be leveraged to enhance Adventus

Mining’s ESG goals in the years to come."
