Oct 23, 2014 | PDF

October 23 2014, Marimaca Copper Corp. (“Coro” or the “Company”) (TSX Symbol: COP) is pleased to announce that the Evaluation Commission of the Atacama Region of Chile, part of the Chilean Environmental Evaluation Service (in Spanish, “SEA”), has approved the Environmental Impact Declaration (“EID”) of the Berta copper project (“the Project”) and has emitted the corresponding Resolution of Environmental Qualification (in Spanish, “RCA”). The Project is located in the III Region of Chile and is owned by SCM Berta (“SCMB”) a Chilean company whose shareholders are Marimaca Copperand ProPipe SA (“ProPipe”), an engineering firm based in Santiago, Chile.

As announced in the Company’s news release NR14-10 on September 3 2014, SCMB and Inmobiliaria y Constructora Fundart Ltda (“Fundart”), a local construction group, have executed a Memorandum of Understanding (“MOU”) which provides US$15m of debt financing for the development of the Berta copper resource, located approximately 20km west of the village of Inca de Oro and for the acquisition of the Nora solvent extraction and electro winning (“SXEW”) plant, located 4km north of the town of Diego de Almagro and 42km north of Berta. Successful completion of the debt financing and planned acquisition of the Nora plant will increase ProPipe’s interest in SCMB to 50%. In our news release NR14-12 on September 15 2014, the Company announced the positive conclusions of a Preliminary Economic Assessment for the Project which is expected to produce 38kt of copper cathode over a mine life of 8 years, generating an after tax IRR of 46.9% and an NPV 8% of US$26.6m.

Alan Stephens, President and CEO of Marimaca Coppercommented, “We are delighted to have achieved this important milestone in the development of the Berta project, with the SCMB environmental team led by Marcelo Cortes, Coro’s VP Development, having done an excellent job in delivering a fully approved EID in less than 12 months. We now look forward to closing the loan financing and taking possession of the Nora plant. In that regard, we have been advised that the time needed to transfer the required surface title and environmental permits from the previous owners of Nora to SCMB will extend beyond our original estimated closing date of October 22 2014.”

SCMB is owned 87% by Marimaca Copperand 13% by ProPipe. Upon filing of the NI43-101 Compliant Technical report for the PEA, ProPipe will increase their ownership to 18%. Upon the successful closing of the non-recourse $15m financing for the development of the Berta copper resources and Nora SXEW plant they will increase their interest in SCMB to 50%.

About Marimaca Copper

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. The advanced San Jorge copper-gold project located in Argentina has been optioned to Aterra Capital and Solway Industries.
