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 small amounts (generally <1%) of electrum, argentite, pyrargyrite, chalcopyrite, pyrite and marcasite.

The Angela Vein is composed of a gangue of white chalcedony, quartz, calcite (minor), smectite and illite. Metallic minerals, which rarely constitute more than 1% of the vein, occur as disseminations and colloform banding, and consist of pyrite, marcasite, argentite, pyrargyrite, chalcopyrite, sphalerite and electrum.

- Production has historically come mainly from the Angela vein;
- Exploitation areas are located mainly at three different levels (4300, 4400, 4500m a.s.l);
- The mine has 3 main accesses, which are interconnected;
- Mining methods: Transversal Open Stoping, Longitudinal Open Stoping, Cut and Fill;
- The mine is backfilled with a mix of tailings and cement.

- subscription is required.

The process plant and associated facilities will process run of mine (ROM) ore delivered to the primary crusher, to produce doré bars and tailing. The process encompasses crushing and grinding of the ROM ore, agitated tank cyanidation leaching, a Merril Crowe circuit and smelting of the precipitate to produce doré bars that are then shipped to a refinery for further processing. Following cyanide destruction, the leached taulings will be thickened before placement in the tailings storage facility (TFS) or used as mine backfill.

The flowsheet incorporates the following major process operations:
• 7 x 4,085 m3 live capacity cyanidation leach tanks in series;
• 4 x CCD thickener washing stages and 1 solution clarifier thickener;
• An 810 m3/h Merrill Crowe circuit;
• Retort system to volatilize and remove mercury from the precipitate cake;
• Diesel fired reverbatory smelting furnace;
• Leached tailings cyanide destruction utilizing the INCO SO2 ........
