F E B R U A R Y / M A R C H 2 0 1 5 www.resourceworld.com 53 Eco Oro Minerals pleased with Colombia land decision eco Oro Minerals corp. [EOM-TSX; GSL- London AIM] reports that the Colombian Ministry of Environment and Sustainable Development has approved Resolution 2090 dated December 19, 2014, wherein the boundaries of the Páramo of Santurbán park have been officially declared. The Resolution provides that within the Santurbán Páramo there are certain areas where mining can take place (Mining Permitted Restoration Areas), subject to stricter environmental controls. The map, as prepared by the company at www. eco-oro.com on the December 22 press release, shows the general layout of prin- cipal mineralized structures relating to the previously-disclosed resource for the Angostura deposit (preliminary economic assessment completed in 2012) in rela- tion to the Santurbán Páramo, Mining Permitted Restoration Area and previ- ously-declared Santurbán Regional Park (see news releases 9 Jan. 13 and 17 Jan 13). As depicted in this map, the boundaries of the Santurbán Páramo extend beyond the boundaries of the Regional Park. Although further work will be required to fully understand the impact of the Santurbán Páramo on Eco Oro and its assets, the company's initial assessment indicates the Santurbán Páramo may affect to some limited extent the development of the Angostura deposit as previously envisioned by the company. Eco Oro was previously known as Greystar Resources prior to the Colombian government stop- ping the project with the creation of the park boundaries over top of its Angostura gold-silver project in northeast Colombia. Eco Oro is currently assessing how the Angostura Project will be developed taking into consideration the Santurbán Páramo. This will include assessing vari- ous techno-economic parameters such as cut-off grade, production rates, min- ing and metallurgical approaches, access to adjacent and at depth resources and the overall infrastructure layout. "We are pleased that the boundaries of the Santurbán Páramo have finally been declared. With the uncertainty relating to the boundaries now out of the way, the company will proceed with reassess- ing how the Angostura Project will be developed," stated Juan Esteban Orduz, Co-Chairman of Eco Oro. Anna Stylianides, President and CEO, stated, "The delineation of the Santurbán Páramo has been the subject of thorough interaction with local communities and other stakeholders. We are committed to developing the Angostura Project in a socially and environmentally sustainable manner to benefit stakeholders, investors and the communities in which we operate." An updated PEA estimates annual produc- tion of 222,000 to 303,000 gold equivalent ounces for 10 years with an average annual production rate of 269,000 gold equivalent ounces. n Accurate multizone groundwater characterization data—from one wellbore. Westbay systems can monitor multiple discrete zones in a single borehole without cross-contamination, acquiring quality groundwater characteriza- tion data while reducing drilling and installation costs. During a complex groundwater investigation in West Virginia, DuPont used Westbay systems to obtain detailed hydraulic data from up to 40 zones in each well, which helped quantify groundwater constituents in less time and at less cost compared with conventional methods.
