Mexoro Minerals Reports High Grade Results at Sahauyacan Project
Thursday, July 26th, 2007
Mexoro Minerals is a precious metals exploration company with mineral properties located in the state of Chihuahua, Mexico. The Company is pleased to provide additional drilling results from its Sahauyacan Property:
Sahuayacan is a classic low-sulphidation gold-silver epithermal district with the mineralization being controlled mainly by north-northwest and northwest striking structures. Economic mineralization is contained in high-grade ore-shoots located along a 4 km mineralized northwest trending structures known as Santo Nino and Santa Teresa.
The last area tested as part of the recently completed drilling program at Sahuayacan was the Santa Teresa target, where two drillholes (SDH-11 and SDH-12) were completed. The objective of those two drillholes is the attempt to extend the areas high grade mineralization and further define the margins of the Sahuayacan mineralized system to the south and southeast of the project area.
The drillhole SDH-12 has intersected a high grade mineralized zone, consisting of 7.5 meters with 56.01 g/t Au and 283.22 g/t Ag The following are the assay intercepts from the Santa Teresa structure:
Hole ID, From(m), To(m), Interval(m), Au(g/t), Ag(g/t)
SDH-12 74.50 76.00 1.50 6.21 148
76.00 77.50 1.50 0.716 8.5
77.50 79.00 1.50 268.75 1215
79.00 80.50 1.50 2.46 39.8
80.50 82.00 1.50 1.93 4.8
Additional check assays of the core from 77.50 to 79.00 returned values of 431 g/t Au and 1,490 g/t Ag over 1.5 meters. These results have not been included in the calculation until they have been qualified and confirmed by the Company. We do expect it to be normal to find these extremely high grade zones in our assays as similar ore was mined in this same area in the early 1900s. Furthermore, other large mineral discoveries by other companies in the area have also reported such high grade zones in their drilling results greatly enhancing the economics of the deposits that have been found. Management is very encouraged by results returned in this hole.
Surface mapping and drilling results are suggesting that the high gold values tend to cluster at certain areas along the Santo Nino and the Santa Teresa vein structures with intervening areas of low gold grades. The cluster of high gold values indicate the development of oreshoots within the extensive Sahuayacan system as evidenced by the intercepts from the SDH-1 in the Santo Nino vein (March 13, 2007 press release, where intersections includes 7.50 meters with 2.56 g/t Au and 8.0 meters with 2.98 g/t Au) and the SDH-12 along the Santa Teresa vein.
Drillholes SDH-11 returned only anomalous gold zones in the structure. SDH-12 shows that the potential for a significant increase in the Santa Teresa mineralization area. As well it appears that the mineralization is controlled by NWN structures running from the Santa Teresa target up to the north to the La Cumbre target. Following the evaluation of the drilling results, Mexoro’s exploration team will further evaluate the Sahuayacan system by reverse circulation drilling at La Cumbre and diamond drilling at Santa Teresa and Santo Nino to test the veins. This program will help to define the potential volume and grade of a large portion of the mineralized veins systems at Sahuayacan.
