Revolution Resources Corp. TSX: RV is pleased to report initial results have been received from the Universo Property, north-centralSan Luis Potosi, Mexico. High grade gold and silver mineralization has been encountered underneath the Cinco Estrellas Mine, highlighted by 42.4 g/t Au with 68.2 g/t Ag over 0.97 meters in diamond drill hole UNN12-010.
Sixteen diamond drill holes totalling 3,607 meters were completed, nine of which were on 75 to 100 meter centers testing the strike and down-dip extensions of the underground workings below the historic Cinco Estrellas mine.
To date, Revolution has identified twenty-five surface showings, prospects, and anomalous zones on the Universo Property. Revolution is currently interpreting the current results, compiled with geological and geophysical data to develop further drill targets in the Cinco Estrellas area.
"Results from Universo suggest the presence of a hydrothermal gold-silver system with similarities to large mines and deposits in this region of Mexico," said Aaron Keay, President and CEO. "These high-grade intercepts, coupled with extensive zones of alteration, are highly encouraging within the same mineral belt that hosts Goldcorp's Penasquito to the north and New Gold's Cerro San Pedro to the south."
Results are highlighted by drill hole UNN12-010 which intersected 3.95m averaging 11.98g/t Au, including 42.4g/t Au over 0.97m with abundant visible gold, starting at a depth of 74.88m. This gold bearing zone occurs down-hole from a broader silver mineralized horizon of 12.89m averaging 26.18g/t Ag, starting at 63.98m. On the same section drill hole UNN12-009 encountered 2.24m of 58.74g/t Ag starting at 66.2m.
Gold and silver mineralization was found to be hosted within caliche overburden such as in hole UNN12-012 from surface, 16.8m of 0.596g/t Au and 14.17g/t Ag. Similarly in UNN12-013 75m to the north of hole 012 encountered 14.92m starting at surface with 0.34g/t Au. Deeper within UNN12-013 at 37.79m is 26.26m of 21.5g/t Ag which contains 11.8m of 34.86g/t Ag starting at 46.87m. Hole UNN12-014 intersected 10.65m averaging 1.22g/t Au, also within caliche. These strongly anomalous gold and silver values suggest potential for undiscovered gold-silver structures under overburden, proximal to the outcropping Cinco Estrellas and Esquival Zones.
Drill hole UNN12-006 intersected a near surface interval of 1.03g/t Au over 22.28m with 5.00g/t Ag starting at 8.84m including 4.6m of 4.37g/t Au over 4.6m and 17.54g/t Ag. The mineralization in this hole is hosted within a quartz-calcite-hematite veined clastic sequence of conglomerates and siltstone with several meters of silicified breccia at the Cinco Estrellas fault contact. This is the southernmost drill hole completed to-date. Drilling has tested a strike length of over 500m and is open to the north and south along the Cinco Estrellas structure.
This first round of reconnaissance style drilling indicates gold and silver epithermal mineralization is hosted within a variety of geologic environments where the combinations of structure and host rock are instrumental in deposition of high grade precious metals. Host rocks such as limestone, silty limestone, sandy siltstone, and coarse volcanic to volcaniclastic rocks of uncertain origins contain silica replacement overprinted by multiple generations of quartz and calcite veining, many of which contain gold and/or silver mineralization. Our surface work to-date focused on structural controls to key alteration and mineralization, and will continue with integration of drill hole and surface data into 3-D models as well as integration of geophysics. Further to the regional prospecting at Universo, the gathering of new information is geared towards structural and alteration subtleties along with interpreting geochemical vectors from surface samples.
Complete drill results are as follows:
*True Widths are estimated to be between 80 and 100% of drilled length.
Revolution's 350,000 hectare Universo Property is centered at the heart of a 300 kilometer long trend of significant precious and base metal mines and deposits. The Property is located to the south of the Camino Rojo gold-silver discovery (Canplats Resources, recently purchased by Goldcorp) and Goldcorp's giant Penasquito gold-silver-lead-zinc mine. Twenty kilometers to the southeast of Universo, the Charcas Mine (Grupo Mexico) is Mexico's largest zinc mine; and 100km further south occurs the New Gold Inc. Cerro San Pedro gold-silver mine. Despite the Property's strategic location, only limited modern exploration has been performed; the last known drilling being eighteen years ago.
Cinco Estrellas is one of several historic mines on the Property. Historic operations exploited a high-grade gold/silver vein, averaging approximately one to three meter widths, as well as several parallel structures. 188 underground channel samples were collected and previously reported; samples range from 0.002g/t Au to 566g/t Au, averaging 6.9g/t Au, and 0.19g/t Ag to >10,000g/t Ag, averaging 121g/t Ag. Samples range from 0.3 to 1.5 meters in length, extending into the hanging wall and footwall of the veins. The purpose of the sampling, which covered significant portions of accessible underground workings, was to identify metal zonation within the mineralized structure. Native gold and silver chloride mineralization is commonly observed within epithermal quartz veins in the underground workings. Gold and silver mineralization is found not only within the broad vein structure but also well into the hanging wall and foot wall rocks.
Ongoing mapping and sampling are refining new target areas at Universo. This includes prospects such as Chiqui, located 15km south of Cinco Estrellas and Salitrillo, located 35km to the north-northwest where historic samples and cursory mapping outlines large areas of jasperiod altered limestone, structurally controlled antimony mineralization and associated gold collected by previous operators up to 7.0g/t Au and multiple of >1.0g/t Au samples. Newly recognized and altered high level intrusive rocks with diatreme characteristics have been identified in proximity to the gold-antimony prospects at Chiqui. Further investigations are underway within and peripheral to the intrusives. The significance of these intrusive units is that they suggest a similar geologic setting to the Camino Rojo and Penasquito deposits located to the north of Universo. The bulk of precious and base metal mineralization at Penasquito is hosted within a pair of high level intrusive pipe-like diatremes with intermediate to felsic composition that display high level clay-sericite alteration.
The Company recently completed underground sampling on the historic Cinco Estrellas mine to a depth of roughly 70m and 7 levels. Extension to the underground workings along strike and at Cinco Estrellas had never been drilled prior to this first phase program.

The Company has ongoing community and local stakeholder dialogue in the Universo area, including surface access agreements recently signed with multiple Ejido groups and several surface land owners.
Revolution's 2012 exploration program at Universo will has been performed under the supervision of Rob McLeod, P.Geo and Director of Revolution and Katie Lucas, P.Geo., both Qualified Persons as defined by NI 43-101. Drill cores are cut in half using a diamond saw, with one half placed in sealed bags, and delivered to ALS-Chemex facilities and/or Activation Laboratories for preparation and analysis using both fire assay and multi-element ICP methods. A sample quality control/quality assurance program utilizing standards and blanks, as well as third-party check labs will be implemented.
