NEWS release December 8, 2014

NEWS release December 8, 2014ECUADOR GOLD ANNOUNCES ENCOURAGING METALLURGICAL TESTWORK RESULTS, A COMPLETION DATE FOR THE SANTA BARBARA PRELIMINARY ECONOMIC ASSESSMENT REPORT AND THE ACQUISITION OF KEY SURFACE LANDS AT SANTA BARBARA PROJECT December 8, 2014 – Toronto, Ontario: Ecuador Gold & Copper Corp. (TSX-V: EGX), (the “Company” or “EGX”) announces that the Company‟s Consulting Engineers, GBM Minerals Engineering Consultants Limited (“GBM”) who are currently undertaking, through Resource Development Inc, (“RDI”) of Denver Colorado, the additional metallurgical test work that was announced in the May 29, 2014 News Release, as part of the 43-101 Preliminary Economic Assessment Technical Report (“PEA”) on the Company‟s flagship Santa Barbara Project, have released encouraging results from this test work and have advised the Company that the PEA will be completed by the end of January 2015. In addition, the Company has acquired key surface landholdings that cover a substantial part of the surface footprint of the Santa Barbara Project. Metallurgical Test Work Update RDI reported that the following conclusions can be drawn from the additional metallurgical test work which incorporates alternative flotation reagents and fine grinding: Copper and gold recoveries achievable by rougher flotation are ± 80% and ± 65%, respectively. Due to the very small particle size of some of the chalcopyrite, as seen in the mineralogy study, the recovery of copper is unlikely to increase without grinding the ore to extremely fine size (i.e. ± 10 mm). Flotation at acidic pH conditions improved copper and gold recoveries in the rougher flotation. Sulfidization of the ore slightly improved copper and gold recoveries in the rougher flotation. The optimum process conditions for the ore are primary grind of P80 of 200 mesh and reagent suite consisting of potassium amyl xanthate (PAX), AP-208 and methylisobutal carbonal (MIBC). Previous metallurgical test work using „whole ore‟ cyanide leaching and a two stage flotation process has resulted in an 86% recovery of gold and a 64% recovery of copper. Based on the metallurgical test work to date the Company believes that a flow sheet based on fine grinding of the rougher tails (P80 of 200 mesh) followed by flotation to recover a copper concentrate and cyanidation of the cleaner and rougher tails will produce recoveries of the order of 80% copper and 80% gold. Additional metallurgical test work during prefeasibility or feasibility studies will improve this flow sheet, optimize reagent consumption and confirm operating costs. The above conclusion and the findings from the previous metallurgical test work program will be incorporated in an optimized metallurgical flow sheet for the PEA. - 2 - Completion Date for the Preliminary Economic Assessment Report GBM have informed the Company that based on the above metallurgical test work results they are now in a position to complete the PEA and have committed to an end January 2015 completion date. Additional Surface Lands Acquisition – Santa Barbara Project The Company has acquired a surface land package of approximately 160 hectares that covers a substantial part of the project footprint for the Santa Barbara Project. This is a very positive step towards the development of the Santa Barbara Project as this land package covers a large part of the proposed open pit, surface processing and infrastructure facilities.
