Guachinango Mining District, Jalisco State, Mexico
The El Barqueño project hosts a significant epithermal bonanza-type vein and stockwork gold system. The project’s deposits could potentially be developed into a series of open pits utilizing heap leach processing, similar to the Creston Mascota deposit at Pinos Altos and the La India mines.

El Barqueño represents a significant new land position for Agnico Eagle in the Guachinango Mining District, part of the Sierra Madre Belt, in the state of Jalisco, Mexico. Extensive exploration drilling on the property has resulted in a substantial initial mineral resource estimate of 19.7 million tonnes of inferred resources grading 0.96 grams of gold per tonne and 5.78 grams of silver per tonne (containing 0.6 million ounces of gold and 3.7 million ounces of silver) as of December 31, 2015. The project contains underexplored zones of gold and silver mineralization in areas of past production, other prospects and drill targets.
The Guachinango mining district lies in the Trans-Mexican Volcanic Belt. Known epithermal vein deposits are related to hydrothermal activity associated with volcanism of the Lower Volcanic Supergroup (LVS) comprising from bottom to top, equigranular and porphyritic andesitic flows and tuff units. The Barqueño pyroclastic units hosting most of the mineralization occur within the upper portion of the LVS. The mineralization consists of gold-silver (copper) veins, stockwork and vein breccia zones hosted in massive to faulted andesitic pyroclastic rocks. Vein widths range from less than 10 cms to several metres, and locally up to tens of metres in width, particularly where the structures intersect.
There are a number of known mineralized zones. The Azteca-Zapoteca prospect has the greatest potential for near-term gold resources, with a strike length of more than 1.4 km and a depth of 300 metres locally. Eight hundred metres northwest, the Angostura prospect has more than 1,000 metres strike length from surface to 335 metres depth locally. Approximately 1,000 metres to the east is the Zapote-Mixteca prospect consisting of northeast-striking veins. The Pena de Oro prospect, 6 km to the east-northeast, has a strike length of more than 800 metres to a depth of 160 to 250 metres locally.
