The Preliminary Economic Assessment (“PEA”) was prepared in accordance with the requirements of the National Instrument 43-101,Standards of Disclosure for Mineral Projects (“NI43-101”) (refer release on 4 August 2020) and is based on a Mineral Resource Estimate (“MRE”) completed by NCL, which comprised 70 million tonnes, with an average grade of 0.60% total copper within the Measured & Indicated Categories of mineral resources (approximately 420Kt of contained copper), and 40 million tonnes with an average grade of 0.52% total copper within the Inferred Category of mineral resources (approximately 224kt of contained copper) (refer release on 2 December 2019). The PEA is considered preliminary in nature and includes Inferred Mineral Resources that are considered too speculative, geologically, to have the economic considerations applied that would enable classification as Mineral Reserves. There is no certainty that the conclusions within the PEA will be realized. The PEA is based on the material assumptions outlined in the PEA and summarized in the press release on 4 August 2020. These include assumptions about the availability of funding. While the Company considers all of the material assumptions to be based on reasonable grounds, there is no certainty that they will prove to be correct or that the range of outcomes indicated by the PEA can be achieved.

Exceptional PEA Results for the Marimaca Project including US$524 million post-tax real NPV8 and 33.5% IRR
Highlights from the PEA Results
Luis Tondo, CEO of Marimaca Copper commented:
“The exceptional results of the PEA have confirmed our belief that Marimaca is a development stage copper project of the highest quality. Its pre-production capital costs places it in the very lowest tranche of projects in the copper development space, while its low operating costs, which places it in the bottom quartile of operating copper mines globally, means that the project will be profitable even in lower copper price environments.
“The Marimaca Project is substantially more de-risked than a typical PEA level project due, primarily, to the significant amount of technical work we have already completed, which includes four phases of metallurgical testing, geotechnical studies, nearly 100,000 metres of drilling over the Project and engagement with various input providers for the Project.
“In a commodity which is dominated by large, technically challenging projects in difficult jurisdictions, that carry with them a level of development and operating risk commensurate with their size and complexity, Marimaca represents a copper development project at the other end of the spectrum. Marimaca is a project, located in a tier 1 mining jurisdiction, that can be both financed and built with lower levels of execution risk, and which provides a platform for Marimaca Copper to become a mid-tier copper producer in the future.”

Notes to Editors
Marimaca is fast becoming recognised as one of the most significant copper discoveries in Chile in recent years as it represents a new type of deposit which challenges accepted exploration wisdom and promises to open up new frontiers for discoveries elsewhere in the country. Marimaca is hosted by intrusive rocks while the numerous manto deposits in the same region are hosted by volcanics. With a lack of new copper exploration discoveries in Chile, the growing Marimaca resource is a high-profile development project as it is situated in the coastal belt at low elevation close to Antofagasta and Mejillones. This prime location could enable its future development at a relatively modest capital investment. Marimaca will benefit from nearby existing infrastructure including roads, powerlines, ports, a sulphuric acid plant, a skilled workforce and seawater.
1 All in sustaining costs is defined as cash cost (C1) plus general and administrative expenses, sustaining capital expenditure, deferred stripping, royalties and lease payments and is used by management to evaluate performance inclusive of sustaining expenditure required to maintain current production levels.
2 C1 cash cost includes all mining and processing costs less any profits from by-products and is used by management to arrive at an approximated cost of finished metal.
