Drilling Starts at Los Crestones
Quaterra Resources 2006-09-28 News Release |
The Crestones hydrothermal system consists of three elongate siliceous hydrothermal silica breccia bodies that range from 500 to 1,500 meters in strike length and 75 to 150 meters in width. They strike NW to N with a steep to vertical dip, and are hosted within an eight square kilometer envelope of silicified limestone that has been brecciated along its contacts of the hydrothermal silica breccia.
The breccias are dominantly composed of white to black saccroidal silica matrix with evidence of multiple phases of silica injection. Breccia clasts consist of silica and silicified limestone. The black silica is clouded with disseminated stibnite-pyrite-marcasite. The breccias and silicification envelope have been intruded by an elongate quartz porphyry stock with weak phyllic alteration.
Mineralization consists of disseminated stibnite-pyrite-marcasite in the siliceous breccia matrix, breccia clasts with disseminated sphalerite-galena and minor disseminated and veinlet galena-sphalerite-tetrahedrite in the quartz porphyry stock. Rock samples from the siliceous hydrothermal breccia have elevated Sb-As-Hg values and anomalous Au-Ag values with occasional spikes up to ore grade. The presence of hot spring bedded siliceous sinter indicates that the outcropping alteration-mineralization is high level and formed close to surface.
The drill program will test all three of the hydrothermal breccia bodies. Continued geologic mapping is in progress to trace the extent of the largest breccia body to the southeast where it continues into a large area of the silicified limestone.
