About Marimaca Copper Corp.:

Coro’s strategy is to grow a mining business through the discovery, development and operation of “Marimaca Coppertype” deposits. These are defined as projects at whatever stage of development, that are well located with respect to infrastructure and water, which have low permitting risk, and which have the potential to achieve a short and cost effective timeline to production. Our preference is for open pit heap leach copper projects, where we will seek to minimise capital investment rather than maximise NPV, where we will prioritise profitability over production rate, and finally, where the likely capital cost is financeable relative to our market capitalization. The Company’s assets include its 65% interest in SCM Berta including the Berta and Salvadora deposits; the Marimaca drill stage project; the Planta Prat project; the Llancahue prospect; and a royalty on the San Jorge copper-gold project located in Argentina.
