CuOro Intersects 6 Metres of 4.9% Copper at the Santa Elena Project in Colombia

VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 31, 2012) - CuOro Resources Corp. (TSX VENTURE:CUA) ("CuOro" or the "Company") is pleased to announce additional drill results from eight drill holes at its Santa Elena Copper-Gold Project, in Antioquia Department, Colombia, with highlights including 6.0 metres grading 4.9% copper in hole SEDDH-84. The Company currently has two drill rigs on the property continuing its Phase I 25,000 metre drill program. To date a total of 100 drill holes have been completed with approximately 19,735 metres drilled (see Figure 1).

Highlights:

  • Hole SEDDH-84 intersected 6.0 metres of 4.9% copper at a down-hole depth of 56.0 metres
  • Hole SEDDH-91 intersected 5.0 metres of 1.2% copper at a down-hole depth of 35.0 metres
  • Hole SEDDH-88 intersected 67.5 metres of 0.22% copper at a down-hole depth of 145.5 metres

All other drill holes not listed in the table above did not return any significant economic values. All widths represent down-hole core lengths and the true widths are unknown at this stage. Average grades are calculated by the average weighted length of each individual intercept over the entire length of the intercept.

CuOro Resources President & CEO, Robert Sedgemore stated, "These new drill results show that we are increasing our understanding of the Santa Elena project and continuing to locate the high grade copper containing massive sulphide mineralization that we are seeking."

Drilling Results

Drill holes SEDDH-84 and SEDDH-91 both targeted a geophysical off-hole conductor that was identified from down-hole Pulse EM surveys in holes SEDDH-79 and SEDDH-83 that also intersected massive sulphide mineralization by (see June 5, 2012 press release). Mineralization was intercepted in drill hole SEDDH-84 approximately 40 metres below surface; and in drill hole SEDDH-91 approximately 25m below surface. The intercepts are 50 metres apart. To date, this newly discovered massive sulphide body is approximately 65 metres in length, strikes N60W, flat-lying and almost parallel to surface at a shallow depth of no greater than 40 metres below surface. Drilling continues in order to define the extent and limits of the mineralized body. Please see Figure 1 for a map of the drill hole locations reported in this release, and Figure 2 for a cross section relating to the drill holes reported in this release.

The Company continues to advance with its aggressive exploration program at Santa Elena that includes a Phase I 25,000 metre diamond drilling program, regional and detailed geological and structural mapping, and geophysical surveying.

Geophysics Update

The down-hole pulse EM results and surface survey EM results display a strong correlation (direct relation) with mineralization; the outcropping massive sulphides and known mineralization at depth. The presence of geophysical anomalies spatially associated with known mineralization is extremely encouraging. The EM survey has proven to be extremely effective in discovering and mapping previously undetected VMS bodies, and drilling has confirmed the validity of the data.

As a result of the successful drilling results, the Company is continuing the EM surface survey outwards in all directions from the current drill area. All drill holes will be tested with the down-hole EM method as they are completed. The ongoing drilling program will make maximum use of the borehole and surface transient electromagnetic surveying to systematically locate and target potential massive sulphide bodies.

Additional Exploration

The Company also reports that channel sampling of recently exposed outcrops at TEM-2 (El Arroyo) at the Santa Elena Project has returned high-grade copper values with an average mean grade of 1.61% copper over 70 metres of surface exposed massive suphides.

Indications are that at TEM-2 the massive sulphides form a tabular zone dipping at 45° to the north and plunging at 40° to the east. The outcrops were previously thought to have a strike length of approximately 10 metres, however, ongoing exploration has shown that the outcropping VMS-style mineralization continues an additional 60 metres to the west increasing the total length of the outcrops to approximately 70 metres.

CuOro President & CEO, Robert Sedgemore stated, "We are delighted to have extended the strike length of the massive sulphide outcrops at TEM-2, which are further evidence of the high-grade copper potential at Santa Elena."

CuOro completed an extensive saw-cut channel sampling program over the exposed sections of massive sulphides. Vertical channel samples were cut at two to three metre intervals where exposure permitted. Due to the limitations of the natural outcroppings this nominal spacing was adjusted to fit the local conditions. The true thickness of the outcrops has yet to be determined.

The program consisted of 15 individual saw-cut vertical channel samples totaling 11.54 linear metres collected over the exposed strike length. The assay results returned an average mean grade of 1.61% copper. The highest individual result from this round of channel sampling was a 0.65 metre vertical channel sample at 3.83% copper. Note that average assays values are calculated using the length weighted average for each sample. Assay results are listed in Table 3.

CuOro staff cut channels on all exposed outcrops. The outcrops were cleaned of debris and plant matter with a high pressure water sprayer. Channels were clearly marked in bright orange spray paint. All channel samples were cut with a diamond saw to a nominal width of five centimeters, three centimeters deep and one meter in length (where feasible) yielding an average 4.4 kilograms per meter of sample length. The resulting channel samples were broken from the cut using a hammer and chisel. Care was taken so that no samples fell to the ground in order to avoid any possible contamination. Channel samples were cut vertically, perpendicular to the true thickness.

Qualified Person

CuOro also announces Iain Kelso HBSc., P.Geo as the qualified person as defined by National Instrument 43-101 who is responsible for the technical information provided in this release and all future news releases. The Company would like to thank Michael Rowland P.Geo for his past work at CuOro Resources as the qualified person.

QA/QC

All drill-hole core and collected field samples were assayed by SGS at its laboratory in Lima, Peru, after preparation at an SGS facility in Medellin, Colombia. Duplicate channel samples were collected for QA/QC control and sent for testing. Standards were also entered into the sampling stream. All channel samples, rock chip samples and stream sediment samples are collected under the supervision of Company geologists in accordance with standard industry practice. Gold was analyzed by fire assay (SGS analysis FAA515); silver, copper and zinc results were determined by 4-acid ICP MS (SGS analysis ICM40B) and AA (SGS analysis AAS41B) techniques.
