Fernandez Zone
The Fernandez Zone has developed along the eastern edge of the central Diorite intrusion and covers a broad area of more than 325 m extending from the Montanez to the Trovador structures. Modeling of this zone outlined a large fringe of lower grade mineralization hosted for the most part in limestone units that surround a core of higher grade Endoskarn (mineralized Diorite) with stockwork-style mineralization. The Fringe Zone encompasses portions of the adjacent Montanez FW, Central and HW veins; the MID-Zone Vein and the AG Zone, recognized as Resource areas in 2009; and parts of the new Lorenzo and South-Skarn and Panda Zones. The Fernandez zone represents a new style of mineralization, potentially amenable to large-sale, bulk mining or more selective approaches.
