These are drill intersections and true widths have yet to be determined.
Hole TC 01-10 and 02-10 both intersected the Tajos Cuates Vein. Hole TC 03-10 intersected two quartz veins in the Veta Tomas structure; a splay of the Tajos Cuates Vein. These two intersections are approximately 150 metres southwest of the underground development on the Tajos Cuates Vein. This is a new zone of mineralization. See figure for reference at the following address:

The Mina Real Project is underlain by a complex of rhyolitic, rhyodacitic and dacitic ignimbrites and trachytes, cut by intrusions of similar composition. Alteration varies from narrow zones adjacent to mineralized veins, to broad zones of moderate to intense clay alteration. The broad zones of clay alteration have drill intersections of at least 50 metres.
The mineralized veins trend northwest to north-northwest, with local northeast-southwest trending offsets. These offset structure/veins locally carry gold and silver values. The northwest trending veins are found in shear zones, which vary in width from 2 or 3 metres to broad zones of shearing that represent regional shear zones.
The veins vary in width from a few centimetres to maximum widths of approximately 10 metres. The veins are composed of quartz. Individual veins may be single quartz veins or multistage quartz veins, often brecciated and often sheared. The contact with the wallrock typically is intensely sheared and badly broken.
“We are pleased with the results of the step out diamond drilling,“ said Eduardo Luna, President and CEO, “which have extended the mineralized structure at Tajos Cuates approximately 30 metres downdip along the Veta 696 structure. This is approximately 25 metres below the area of underground development and production on the Chalata level, and approximately 100 metres along strike from development and production on the Tajos Cuates level. The upper intersection of Hole TC 02-10 is very encouraging and indicates the potential for ore shoots with significant widths“ The Tajos Cuates Vein is currently the main source of mill feed and is producing positive operating results (see News Release dated May 4, 2010).
Additional drill results are being compiled and will be released as they become available.
Andrew Gourlay, P. Geol., is the Qualified Person for the technical disclosure in this news release. All samples are prepared and analyzed by the SGS de Mexico, S.S., laboratory in Durango, Mexico, and ISO certified and independent laboratory. Standard reference materials, blanks and field duplicate samples are inserted prior to the shipment from site to monitor the quality control of analytical data.
