Marimaca Announces Conversion of $12 Million Loan at Subsidiary Level

Vancouver, British Columbia, Ju ly 2, 2020 – Marimaca Copper Corp. (“Marimaca Copper” or the

“Company”) (TSX: MARI) is pleased to announce that Greenstone Resources II L.P. (“Greenstone”) has

exercised its conversion option (the "Conversion") pursuant to the US$12.0 million convertible loan facility

associated with certain of Marimaca Copper’s subsidiaries, Sociedad Contractual Miner a Berta (“SCM

Berta”) and Rising Star Copper Limited (“RSC”). These subsidiaries hold an interest in the Nora project,

which consists of a processing plant and certain mining concessions, which are not connected to the

Marimaca deposit. The conversion occurred at the RSC level, resulting in Greenstone now holding a 75%

equity stake in the Nora project and Marimaca Copper holding the remaining 25% interest.

As a result of the Conversion, Marimaca Copper no longer controls RSC or SCM Berta and will de -

consolidate those operations from its financial position and operating results effective June 30, 2020. Going

forward, Marimaca Copper’s interest in RSC and SCM Berta will be accounted for using the equity method

which should result in a strengthening of the Company’s financial position as a majority of the outstanding

debt presented on the Company’s balance sheet is associated with SCM Berta. As at March 31, 2020,

approximately $19.2 million of the Company’s outstanding debt was related to SCM Berta.

The Conversion is in line with the Company’s 19 April 2018 News Release which announced the strategic

decision by the Company to focus exclusively on the Marimaca project, and for the unconnected Berta

mine and Nora processing plant to be financed at the project level with no recourse or further dilution to

Marimaca Copper. In February 2019, the Berta mine was sold to Santiago Metals Proyecto 4 Ltda. (refer

to News Release dated 19 February 2019).

The convertible loan facility was approved by minority shareholders in June 2018 as Greenstone is a major

shareholder of Marimaca Copper with a current 24.9% shareholding. In connection with the Conversion,

Greenstone and Marimaca Copper have entered into a shareholders’ agreement and a management

services agreement in respect of RSC and SCM Berta to manage the Nora project on a go forward basis.

Michael Haworth, Executive Chairman of Marimaca Copper commented:

“We have made significant progress in our corporate restructuring efforts as part of wider initiatives for

Marimaca Copper. The objective of these initiatives is to focus attention on our flagship Marimaca Project,

and to streamline the corporate and capit al structure to best position us for its successful future

development. The de-consolidation of approximately $19.2 million of SCM Berta debt from the Marimaca

Copper balance sheet is a further step in this process.

“The PEA for Marimaca is progressing well and we continue to believe it will show that Marimaca will be a

standout copper development project, with low upfront capital costs and competitive operating costs that

has the potential to deliver compelling economics at a variety of copper prices.”

Marimaca Copper Project Overview

Marimaca Copper released an updated Mineral Resource Estimate (“MRE”) for Marimaca of 70 million

tonnes, with an average grade of 0.60% total copper, within the Measured & Indicated Categories

(approximately 420Kt of contai ned copper) and 40 million tonnes, with an average grade of 0.52% total

copper, within the Inferred Category (approximately 224kt of contained copper) ( refer release on 2

December 2019). This represents an increase of almost 100% from the MRE released in A pril 2018 and

makes the Project one of the most significant copper oxide discoveries in Chile in the last decade.

The Company is currently undertaking a PEA for the Project, which is anticipated to be completed in July

2020. The Project is expected to ben efit from low upfront capital development costs and, due to the

favourable geometry of the orebody and relatively simple oxide processing through SX-EW, Management

believes the Project will have very competitive operating costs, delivering compelling economics in the PEA.

Overview of Transaction and De-Consolidated Debt

SCM Berta Facility

In June 2018, RSC entered into a US$12 million convertible loan facility whereby Greenstone provided a

convertible loan to RSC and Minera Coro Chile SpA, both wholly owned subsidiaries of Marimaca Copper.

The facility was convertible into a 75% equity interest in RSC which is the UK parent company of SCM Berta.

As at 31 March 2020, the outstanding balance comprised US$12.0 million in principal, US$3.6 million in

interest and US$0.2 million in arrangement fees.

Greenstone has given notice to convert all of the US$12.0 million principal outstanding into fully paid

ordinary shares in RSC representing 75% of RSC’s issued share capital.

SCM Berta Working Capital Loan

In September 2018, SCM Berta entered into a credit facility with Greenstone for a US$10 million secured

loan facility. As at 31 March 2020, the outstanding balance comprised US$2.0 million in principal, US$0.9

million in accrued interest and US$0.2 million in arrangement fees.

According to the terms of the SCM Berta Facility and the SCM Berta Working Capital Loan, upon conversion

of the SCM Berta Facility, all outstanding accrued interest and fees with respect to these facilities become

payable on demand by RSC. It is important to note that this outstanding debt is payable only at the SCM

Berta level and has no recourse to the Marimaca project.

In the conversion notice for the principal under the SCM Berta Facility, Greenstone elected not to enforce

this obligation at this time. As part of conversion arrangements, it has been agreed that there remains an

outstanding balance of approximately US$7.4 million, which comprises:

1) US$4.2 million in accrued interest for the SCM Berta Facility; and

2) US$2 million principal and US$1.2 million in accrued interest and fees for the SCM Berta Working

Capital Loan.

These items are non-recourse to Marimaca Copper and are limited to RSC and its subsidiaries. As RSC is

now only 25% held by Marimaca Copper, these debts will no longer be consolidated into Marimaca

Copper’s financial accounts effective 30 June 2020.

ProPipe Liability

The SCM Berta Facility was conditional on the Company acquiring a 35% minority interest in the Berta

Mine. This acquisition price was structured over one upfront payment and three future instalments. The

ProPipe Liability is also non-recourse to Marimaca Copper and is limited to RSC and its subsidiaries. As at

31 March 2020, the balance of the ProPipe liability was US$0.5 million. This amount will also be de -

consolidated from the Marimaca Copper balance sheet effective 30 June 2020.

Marimaca Copper and the Marimaca Project

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 developme nt at a reduce capital cost relative to many other copper developments .

Marimaca will benefit from nearby existing infrastructure including roads, powerlines, ports, a sulphuric

acid plant, a skilled workforce and seawater and a relatively low environmental impact.
