El Bolante is a robust quartz vein hosted in potassic-altered quartz-diorite porphyry. Seven channel samples across El Bolante yield results of 6.4 g/t Au and 56 g/t Ag across an average width of 1 meter (samples 15526-15531 and 15600), including an interval of 12.1 g/t Au and 102 g/t Ag across 1.6 meters. Mineralization consists of massive, white, high-temperature quartz hosted with box works after primary base metal sulfides and/or oxides. Open space filling textures are absent, so the veining is not likely epithermal in origin. In the selvedge to the Bolante vein, alteration minerals include primary biotite and retrograde chlorite. Biotite is an iron-rich potassic mineral that is not typical of epithermal systems, but occurs mainly with intrusion-related mineral deposits. To the south of the main Bolante structure, a second parallel structure was exposed in a caved prospect pit. A sample from the dump contained 40.1 g/t Au and 211 g/t Ag (sample 15587). To the north, a grab sample of float boulders with semi-massive goethite botryoids and interstitial quartz contains 1.7 g/t Au and 37 g/t Ag (sample 15599).
