Levon Resources Ltd. is pleased to announce the startup of the 5,000 m core drilling campaign at the Cordero Ag, Zn, Pb, Au discovery, 35 km north of Hildalgo Del Parral, Chihuahua, Mexico, previously announced by the Company on April 4, 2017. 200 m core holes are planned to infill drill a central part of the 2014 resource, (news release of October 20, 2014) to explore for improved near surface resource grades.
The holes are being drilled in the Cordero Felsic Dome Complex (central) portion of the resource that spans four host igneous intrusive centers (Figure 1). If the drilling is successful, results can improve the projected economics of a starter open pit being evaluated by Independent Mining Consultants (IMC), Tucson, Arizona.
Current detailed geologic surface mapping in 2016 and 2017, and past drill results reveal abundant multiple intrusives within the Cordero Felsic Dome Complex that range from several meters (m) to 150 m in diameter, and the intrusives are generally enclosed in high grade, mineralized contact breccias that were often missed by the wider spaced resource grid drilling. Infill drilling is planned at 50 to 75 m centers in angle holes in targeted clustered intrusive areas to test for improved bulk tonnage grades.
A 3D reevaluation of all existing project data, and current geologic mapping reveals that the youngest intrusives within the Cordero Dome and the adjoining Pozo de Plata Diatreme, are silicified rhyolites that host the best gold in the resource. Best gold values of the resource to date are in the Pozo de Plata Diatreme. A 0.07 g/t Au shell within the resource extends from the Diatreme up into the Cordero Dome through the youngest silicified and veined rhyolite domes that form the highest peaks in the Cordero Dome Complex. The youngest rhyolites have not been drill tested for Au to date. About 50% of the planned 2017 drilling is aimed at starting to test the youngest rhyolite domes of the Cordero Felsic Dome Complex for Au.
