Marimaca Copper: Appointment of Company President

VANCOUVER, British Columbia, July 20, 2020 (GLOBE NEWSWIRE) — Marimaca Copper Corp. (“Marimaca Copper” or the “Company”) (TSX: MARI) is pleased to announce the appointment of Mr. Hayden Locke as President of Marimaca Copper, effective immediately. Mr. Locke will be working alongside the Company’s CEO, Mr. Luis Tondo, and Executive Chairman, Mr. Michael Haworth.

Hayden is a highly experienced mining executive, having spent the latter part of his career developing and leading successful LSE and ASX-listed mining companies. Prior to that he worked in investment banking with J.P. Morgan and mining private equity with Barclays Natural Resource Investments.

Since early 2018, Mr. Locke has been Chief Executive Officer of AIM-listed Emmerson Plc (“Emmerson”), a Moroccan focused potash development company, where he remains on the board as a Director. Prior to this, Hayden was Head of Corporate for ASX-listed gold developer Papillon Resources, which was acquired by B2Gold in late 2014 for US$600 million, and Head of Corporate and Technical Services (Geology, Mining and Processing) with ASX-listed potash developer, Highfield Resources.

Michael Haworth, Executive Chairman of Marimaca Copper commented:

“We are delighted that Hayden has agreed to bring his wealth of experience to Marimaca Copper as the Company’s new President. The Company is at a pivotal moment in its development. We believe we are on the verge of unlocking the significant exploration potential of our flagship Marimaca Copper Project and in our extensive claims package surrounding it. Hayden has a proven track record developing and executing value creating strategies in companies in both the exploration phase as well as in financing and development. This experience will be vital for our Company as we seek to realise the true value of our assets.”

Hayden Locke, President of Marimaca Copper, commented:

“I am delighted to be joining Marimaca Copper at this exciting time in its development. The Marimaca Copper Project is one of only a handful of new copper discoveries that has been made in the last five years, and the ongoing, untested, exploration potential within the Company’s claims package, as evidenced by the recent announcement with respect to the magnetic anomaly at the Marimaca Project, is extremely compelling.

“I look forward to working with Mike, Luis and the broader Marimaca Copper team as we continue to progress the Marimaca Project and assess the exceptional exploration potential in its extensive land package.”

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.
