About Llancahue

The Llancahue project is 100% owned by Marimaca Copperand is located 38km south west of the City Of Talca in the VII Region of central Chile, at an elevation of less than 200m asl. In 2009, two reverse circulation drill programs were completed, returning a best intercept of 100m at 1.37% copper, as disclosed in the Company’s news release of May 28 2009. The drilling to date suggests that this mineralization, which occurs in a porphyritic intrusive and its brecciated contact zone, may be of restricted areal extent. However, the intensity of the alteration and the accompanying high grade copper molybdenum mineralization, together with the extensive propylitic halo, support the concept that a larger body of mineralized diorite or breccia complex may be present.

Alan Stephens, FIMMM, President and CEO, of Marimaca Copper Corp, a geologist with more than 39 years of experience, and a Qualified Person for the purposes of NI 43-101, is responsible for the contents of this news release.

About Coro

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.
