Large Bulk Mineable Targets Part of an Emerging Porphyry District
The 20,000-hectare Cordero property encompasses two high-level porphyry districts within the Chihuahua-Zacatecas porphyry belt, an emerging trend that includes Penasquito (Goldcorp), Camino Rojo (Canplats), San Agustin (Silver Standard) and others. Cordero contains a large, 8 km x 3 km mineralized system with discovery potential for multiple bulk tonnage, open pit deposits and extensive, open-ended geochemical and IP anomalies. Drilling in 2009 encountered significant mineralization, and a major drill campaign has begun for 2010.
Along A Major Silver, Gold, Lead and Zinc Belt
In Chihuahua and Zacatecas, a number of new discoveries are outlining an area that appears to constitute a major silver, gold, lead and zinc porphyry belt. Cordero covers well-mineralized intrusive centres that have not been fully appreciated or explored within this belt. Small-scale, ongoing underground production on high-grade silver and zinc breccias and vein zones at Cordero contain significant gold values and support the broader exploration potential for major deposits.
Focus on Four Porphyry Targets
Four main targets now constitute the current exploration focus:
Cordero comprises disseminated and vein-hosted pyrite, sphalerite, galena and argentite mineralization developed in several ENE-oriented structures. The geological setting is similar to the Penasquito Mine.
Sanson consists of a 1,500-metre dome formed by the intrusion of a single quartz monzonite porphyry into the host sediments. Trenching and drilling have encountered quartz molybdenum stockwork mineralization. The system shows a number of similarities with the Penasquito Mine and Camino Rojo and San Agustin projects.
Pozo de Plata (Silver Well) was discovered in late 2009, and it expanded the porphyry district by about 2 km to the southwest along the strike of the mineralized porphyry belt. This new target is defined by mapping and sampling results that establish the presence of a poorly exposed, mineralized rhyolite dike and diatreme complex in an area of alluvial cover. There is no evidence of past exploration work in this area except for the accidental exposure of silver bearing breccias in a recently deepened water well.
Dos Mil Diez, discovered by surface mapping and prospecting at Cordero-Sanson in January 2010, Dos Mil Diez has broadened the mapped extent of the belt another two kilometres southwest of Pozo de Plata into an area of limited bedrock exposure. Ongoing mapping has now delineated a two-kilometre-diameter area defined by circular features comprised of additional hematite stained breccia and islands of domed limestone country rocks. The Dos Mil Diez zone adds significantly to the project's overall potential. Current interpretations of this new zone are that it may represent a surface expression of a larger diatreme complex.
With the addition of the Dos Mil Diez zone the prospective mineralized belt, as defined by five porphyry or intrusive centres, has now been defined through a strike length of 8 km and a width of about 3 km. Current exploration is focused on four of the five intrusive centers, targeting deposits geologically similar to Penasquito, Pitarrilla and Camino Rojo.
Outstanding Values in 2009 Drill Campaign
An 8-hole, 2,840m HQ core drill program at Cordero in 2009 generated outstanding results, including 152 metres grading 80.6 g/T silver, 0.61 g/T gold, 1.41% zinc and 1.22 % lead, and included 72m grading 150.16 g/T silver, 1.06 g/T gold, 2.48% zinc, 2.27% lead in diatreme breccia. This program tested five targets within the Cordero Porphyry Belt. Details of the 2009 drill program are availabe in Levon's News Releases dated November 3 and November 24, 2009.
Excellent Infrastructure near Population Centre
The property and region host excellent infrastructure with ample power and water plus easy road access. The nearby town of Hidalgo Del Parral (pop. 102,000), just 37 km southwest by road, offers a rail head, supplies and skilled mining labor.
Drill-Ready with Large Unexplored Areas
The Cordero-Sanson projects are drill-ready and open to the west for further exploration. Previous operators completed geological mapping, soil geochemistry, bulldozer trenching and an IP survey on the core areas. Old drill holes, completed by Apex, have also been re-logged. The results showed an average intersect grade of 0.77% Zn, 0.43% Pb, 1.20% Pb+Zn, 44 g/t Ag and 0.11 g/t Au. Cordero intersections included:
- 75m @ 47g Ag, .78% Pb+Zn, .09g Au
- 63.9m @ 70g Ag, 2.2% Pb+Zn, 0.15g Au
These grades are broadly comparable with current similar projects in Mexico.
51/49 Joint Venture with Valley High Ventures
By spending C$1.25 million in exploration, Levon completed its option to earn a 51% interest in Cordero Sanson in 2009. Levon is now the project operator, with Valley High Ventures holding a 49% interest.
