The Inmaculada deposits can be clasified as low to high sulfidation epithermal silver-gold deposits. Deposit sub-types on the Property includes LS type which includes the Au-Ag quartz veins at Quellopata including the Angela Vein, IS type and HS type which includes mineralized breccias at Minascucho, Central and San Salvador and disseminated mineralization at Tararunqui.
Rock chip sampling has shown that consistently high gold vaues (from 1 to over 10 g/t Au) are present in the Angela Vein, in the vicinity of line 10,000N of the local grid.
The Angela Vein outcrops in the central portion of the Quellopata vein system. The vein strikes northeasterly (050º), dips to the southeast (45º to 90º) and outcrops on surface along a strike lenght of 700 m.
The vein varies in thickness from 0.5 m to us much us 16.0 m, and has been tested over a vertical extent of up to 3000 m.
Two generations of mineralization have been observed in the Angela Vein, an early lead-zinc event and a later gold-silver event. The early mineralization consists of white quartz veinlets with sphalerite, galena, pyrite and argentite (minor). These veinlets form a broad, low-grade envelope (0.2 to 1.0% Pb + Zn) which surrounds, and overlaps, the Angela Vein mineralization.
The second mineralizing event at the Angela Vein is the most important economically, and consists of a white chalcedony vein with associated breccia and stockworks. The chalcedony contains s ........
