October 24 , Marimaca Copper Corp. (“Coro” or the “Company”) (TSX Symbol: COP) is pleased to announce that, further to its news release of December 9 2013, it has signed a Definitive Agreement (“DA”) with a group comprised of Aterra Investments Ltd. (“Aterra”) and Solway Industries Ltd. (“Solway”), (collectively, the “Group”) for them to acquire an interest in the Company’s San Jorge project (the “Project”), located in the province of Mendoza, Argentina. The Group may acquire a 70% interest in the Project, with the provision for an early buy-out of Coro’s interest subject to Coro’s retention of a 2.5% Net Smelter Return (“NSR”) on the production of all payable metals from the Project, except gold.

Alan Stephens, President and CEO of Marimaca Coppercommented, “We are pleased to have concluded this Definitive Agreement with our partners, Solway and Aterra, who have been operating Minera San Jorge and funding the Project since we signed a Heads of Agreement with them last December. We look forward to them successfully obtaining the outstanding environmental permissions for San Jorge and developing it, which would allow our shareholders to benefit, either through our 30% ownership interest or from the proceeds of a valuable NSR.”

“Coro’s strategy is to own significant interests in a number of copper development projects that can be brought into production quickly and cheaply. These currently include our anticipated 50% interest in the Berta project, which we expect to be in production in 2015; our option to acquire a 65% interest in the Planta Prat project; and our option to acquire a 75% interest in the Marimaca project, all located in Chile. Our objective is to be a self-funding copper growth company, and retention of a significant interest in San Jorge fits well within this strategy. “

“We are pleased to continue our cooperation with Marimaca Copper Corp. on the San Jorge Project in Mendoza. I believe that Solway Investment Group’s expertise in managing projects of this scale in developed agricultural regions, together with Coro’s knowledge of the Project and Aterra’s well-balanced investment strategy will produce a very successful outcome. Our objective is to create an up to date, modernized, ecologically safe and well-maintained business that will secure a high level of employment and significant tax return to the region”, said Dan Bronstein, CEO of Solway Investment Group.

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. Partners will be sought for any attractive projects identified that we do not have the financial capacity to develop alone. Coro’s properties include the Berta pre-production project, the Planta Prat copper development project, the Celeste Sur iron ore project and the Marimaca & Llancahue copper exploration prospects, all located in Chile, and the advanced San Jorge copper-gold project located in Argentina/
