Summary
La Sarita property now in the advanced stages of exploration, encompasses historic small-scale mine workings and several areas of copper and iron oxides in outcrops and trenches. Old mine workings are developed on structurally controlled epithermal quartz-carbonate veins and associated lateral replacement zones. Disseminated and replacement type copper mineralization also occurs on the property in mineralized out crops > 100 meters in diameter. The mineralization types appear to include porphyry-style disseminated copper, porphyry-related skarn-manto replacement zones in limestone, and epithermal quartz-carbonate copper-silver veins.
Rock geochemical sampling conducted at selected sites in (2008 by Mac Ore S.A. de C.V) verified the presence of copper and silver mineralization, and corroborates results from previous sampling. Geochemical analyses conducted by Mac Ore S.A de C.V, returned significant values for copper and silver. The results indicate potential high-value silver-copper mineralization in structurally controlled veins and replacements zones, and potential for low-grade, bulk mineable silver and copper mineralization disseminated in granodiorite.

Location and Access
Leaving from Hermosillo Sonora, Mexico angling toward the northeast by the CF 14 highway approximately 165 kilometers, one arrives at the town of Moctezuma (2.5 hrs), the closest population center to the La Sarita property with supplies and services. The La Sarita Project is located 24 kilometers in a straight line to the ESE of the town of Moctezuma, Sonora. The La Sarita Property consists of 893 hectares and is owned 100% by Quirina Vasquez Vargas.
Description
The main mineralized underground structure now measures 60 meters in width, 40 meters long, and 33 meters deep and still in strong mineralization. In December of 2010, using a D8 dozer, the mineralized zone was further excavated by cross cutting the mineralized structure in front of the main portal in a west to east direction. This cut significantly exposes the main structure now measuring 60 meters in width.
The mineralization is intensely oxidized and consists of malachite and azurite, with possible tenorite. Gangue minerals include abundant goethite and hematite, quartz, calcite and fluorite. At the portal, the mineralized zone is weathered such that quartz forms a distinctive network texture of drusy quartz veins. Just inside the portal, where weathering is not as severe, calcite and locally fluorite are observed in the matrix of the quartz network.
A second vein-like zone of quartz network, very similar and parallel to that of the main portal, was uncovered 50 to 100 meters further east by a dozer that was working on site during the site visit. This new zone has not been sampled, however, traces of copper malachite can be observed. Approximately 150 meters NE of the portal on the other side of the hill, another zone of quartz network almost identical to that of the portal, outcrops at an elevation of 1355 meters and can be seen outcropping to the east for at least 100 meters. The quartz network at the portal is at an elevation of 1347 meters.
Over 40 rock chip samples have been taken inside the main underground structure. The approximate average of the grades in Zone 1, has an average width between 8-10 meters and an average grade of 110.4 g/t Ag and 2.07% Cu. the highest being 459 g/t Ag and 6.84% Cu over two meters. Zone 2, located to the NW of Zone 1, has an average width of 10 meters and an average grade of 22 g/t Ag and 1.33% Cu. the highest being 55.3 g/t Ag and 3.76% Cu. And a third secondary zone, located outside of portal # 2 and 8 meters to the SE from Zone 1, a chip sample was cut across 1.5 meters and had a value of 120 g/t Ag and 7.55% Cu. The most significant Cu-Ag values (250 to 459 g/t Ag and 3.0% to 6.84% Cu.) correlate with strong alteration, zones of fault breccias, quartz veining, silicification, oxidations and argillization related to the N25°-N45°E fault zones with dips of 60-80°NW. Specifically the highest values correspond to zones of 2.0 to 6.0 meters in width.
Geology
La Sarita is a property of merit and continued exploration is recommended. Reconnaissance exploration work has successfully identified high-grade silver mineralization in veins, high grade copper in replacement zones, and disseminated style copper mineralization. Exploration should continue, aimed at evaluating the known zones, identifying high grade zones, and exploring the area for a large zone of low-grade copper mineralization (Dr. Matt Ball, P.Geo. page 2, La Sarita Technical Report).
Technical report in compliance with NI 43-101 is available upon request. The property has a completed 3DIP survey, and 4 different reports made by qualified geologist.
History
In December 2010, six trenches were made by way of dozer exposing 6 new zones of visible copper mineralization on new additional targets throughout the property, trench # 1 located 1400 meters north from the main underground workings, uncovered visible copper oxides and occasional chalcopyrite in granodiorite over 100 meters in diameter. Trench #2, 50 meters below in elevation on the same hill, measures 50 meters in length, also exposes the same mineralization of continuous copper oxides.
Trench #3 located 250 meters SW from Trench #1, measures 80 meters in length and 5 meters in width and exposes continuous copper oxides for the entire length and width of the 80 meters. Trench #4, located 650 meters directly west from trench #3, is 1 meters deep and over 80 meters in length showing continuous copper oxides. Trench # 5, located 400 meters north of the main portal exposes continuous copper oxides along with some sulfides for the entire 60 meters. Trench # 6, located 550 meters directly west from the main portal also exposes continuous copper oxides for 20 meters in length. There are many other outcrops bearing copper oxides on the property that still need to be evaluated.
