Geology and Mineralization
The Pilar property covers the Guarinos and Pilar Greenstone Belts and a portion of the Moquém gneissic complex. The Guarinos Greenstone Belt is represented by a succession of basic rocks, mostly basalt and amphibolite, and by metasedimentary layers, related to inter-flow sedimentary events. Chlorite-quartz-garnet-schist is also present. The main structure is the Carroça Shear Zone, a reverse-dextral major shear zone, parallel to the main regional foliation with several kilometres of strike length. The shear has a mylonitic fabric and an associated 400 m wide hydrothermal alteration zone.
