CuOro Reports Positive Preliminary Metallurgical Test Results of 94.6% Copper and 97% Gold Recoveries at Santa Elena Project
CuOro Reports Positive Preliminary Metallurgical Test Results of 94.6% Copper and 97% Gold Recoveries at Santa Elena Project
VANCOUVER, BRITISH COLUMBIA - September 18, 2012. CuOro Resources Corp. (TSX-V: CUA) (OTCQX: CRUOF) (“CuOro” or the “Company”) is pleased to announce that it has received positive preliminary results for its initial metallurgical test work from the Santa Elena VMS project in Colombia.
Preliminary Metallurgical Testwork Highlights
- 94.6% copper and 97.1% gold recovery for massive sulphide sample
- 89% copper recovery from secondary disseminated sulphide sample

MS – Massive Sulphides, DS – Disseminated Sulphides, ND – none detected
CuOro Resources President & CEO, Robert Sedgemore stated: “These initial metallurgical test results were surprisingly high on both the copper and gold recoveries with excellent results in the mid 90% range. Recoveries are typically in the mid to high 80% range so we are very pleased with these results.”
Summary of Metallurgical Testwork
CuOro retained SGS Mineral Services of Lima, Peru, to conduct the metallurgical testwork. Two test samples were provided: sample SM-01 Massive Sulphide weighed 113.84 Kg and was taken from the core of four separate drill holes. Sample DS-01 Disseminated Sulphide weighed 87 kg and was taken from the core of three separate drill holes. The samples where milled, split and assayed. Reagents and lime were conditioned at a pH of 10 for 3 minutes with a 1kg representative sample and then a single stage rougher flotation test was carried out in a 2-liter Denver rougher flotation cell for 8 minutes. The results and test parameters are provided in Table 1.
The kinetic flotation test aimed to study the effect of the type of reagent on copper and gold recovery. The massive sulphide composite (114 kg), with a head grade of 3.29% Cu and 0.163 g/t Au, produced recoveries of 94.6% Cu and 97.1% Au. The disseminated sulphide composite (87 kg), with a head grade of 0.13% Cu and 0.046 g/t Au, produced recoveries of 89.0% Cu and non-detectable recoveries for Au. The recoverable copper exists primarily in chalcopyrite, along with trace amounts of chalcocite, digenite, covellite and bornite. The excellent gold recoveries indicate that the majority of the gold is hosted with the chalcopyrite mineralization.
Additional locked cycle and cleaner flotation test work is being carried out on the remaining samples to determine the optimal base line flotation parameters, in addition to secondary flotation tests for the recovery of zinc and silver.
About CuOro Resources Corp
CuOro is a Canadian publicly listed exploration company with two exploration projects in Colombia. The company flagship Santa Elena copper project, located in Antioquia is prospective for high-grade near surface VMS copper deposits. The current 25,000m drill program is nearing completion with recent results returning assays of 6.0m at 4.9% Cu (July 31, 2012 Press Release). The Company is well capitalized and has the right to acquire 100% interest in the Santa Elena Property. It is managed by an experienced management and technical team that resides in Medellin, Colombia. The long-term growth strategy is to continue identifying and acquiring new assets in South America with a focus on copper and gold, and the commitment to upholding the highest environmental and social standards.

Forward Looking Statement
Statements contained in this news release that are not historical facts constitute “forward-looking statements” or “forward-looking information” within the meaning of applicable securities laws and are based on expectations, estimates and projections as of the date of this release. Forward-looking statements include, without limitation, possible events, statements with respect to possible events, the future price of gold and silver, the realization of mineral resource estimates and success of exploration activities. The words “is expected” or “estimates” or variations of such words and phrases or statements that certain actions, events or results “may” or “could” occur and similar expressions identify forward-looking statements. Forward-looking statements are necessarily based upon a number of estimates and assumptions that, while considered reasonable by the Company as of the date of such statements, are inherently subject to significant business, economic and competitive uncertainties and contingencies. The estimates and assumptions of the Company contained in this release which may prove to be incorrect, include, but are not limited to, (1) the discovery and expansion of mineral resources on the Company’s Property being consistent with the Company’s current expectations; (2) the implementation of Colombia’s mining law and related regulations and policies being consistent with the Company’s current expectations; (3) certain price assumptions for gold and silver. Known and unknown factors could cause actual results to differ materially from those projected in the forward-looking statements. Such factors include, but are not limited to: fluctuations in the spot and forward price of gold or certain other commodities; changes in national and local government legislation, taxation, controls, regulations and political or economic developments in Canada, Colombia or other countries in which the Company does business or may carry on business in the future; business opportunities that may be presented to, or pursued by, the Company; operating or technical difficulties in connection with mining activities; the speculative nature of gold exploration and development, including the risks of obtaining necessary licenses and permits; diminishing quantities or grades of reserves; and contests over title to properties, particularly title to undeveloped properties. In addition, there are risks and hazards associated with the business of gold exploration, development and mining, including environmental hazards, industrial accidents, unusual or unexpected formations, pressures, cave-ins, flooding and gold bullion losses (and the risk of inadequate insurance, or the inability to obtain insurance, to cover these risks). Many of these uncertainties and contingencies can affect the Company’s actual results and could cause actual results to differ materially from those expressed or implied in any forward-looking statements made by, or on behalf of, the Company. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Forward-looking statements are provided for the purpose of providing information about management’s expectations and plans relating to the future. All of the forward-looking statements made in this release are qualified by these cautionary statements and those made in our other filings with the securities regulators in Canada. These factors are not intended to represent a complete list of the factors that could affect the Company. Although the Company believes that the expectations in the forward-looking statements are reasonable, actual results may vary, and future results, levels of activity, performance or achievements cannot be guaranteed.
