Michael Haworth, Executive Chairman commented:

“The Marimaca Copper Project is one of the most significant copper oxide discoveries in Chile in a decade, and today’s announcement symbolises the commencement of an exciting new chapter in the Company’s evolution.
We have a clear focus on developing Marimaca, which we believe has all of the hallmarks of a low capital cost, high margin, copper development project. A Preliminary Economic Assessment for the Project is underway, which we expect will show the project has robust and compelling economics across a broad range of copper prices.
In addition, we remain very excited about the ongoing exploration potential at Marimaca, especially in the near mine oxide potential and for extensions at depth in the sulphide zone. Any exploration success will only add to what is already a tremendous investment case. We are making significant progress on the various technical de-risking workstreams an
d we look forward to releasing the results of these programs to the market when they are complete.”
