High-Grade Structures and Veins – Vetas Condor Target:
The Vetas Condor high-grade gold – silver epithermal mineralization is encountered on the western flanks of the Cerro del Medio target area where east-west trending quartz – alunite structures are exposed over a 1 km by 350 m area. The previous operator completed a total of 1,100 m of horizontal exploration tunnels that were oriented sub-parallel to parallel to the quartz-alunite ledges. Evidently, crosscuts oriented perpendicular to the structures were not completed and therefore true width of the high-grade mineralization was not determined.
The initial 200 m of the tunnel are oriented sub-parallel at a 20-degree angle to the mapped quartz – alunite structures. Highlighted intercepts from this section of the tunnel, while not true width, demonstrate the high-grade potential of the structures, and include 2.38 g/t gold and 101 g/t silver over 32 m and 0.66 g/t gold and 13.5 g/t silver over 134 m. In addition, approximately 436 m into the tunnel, a high-grade vein sampled 58 g/t gold and 27 g/t silver over 2 m. Table 2 below summarizes the significant intercepts in the exploration tunnel.

Torq’s technical team believes that the high-grade mineralization encountered in the tunnel has not been adequately tested. There have only been three shallow drill holes testing the veins encountered in the first 200 m of the exploration tunnel, which included 6.82 g/t gold and 16.8 g/t silver over 20 m at a depth starting at 110 m (true width unknown). Table 3 below summarizes drill results from the three drill holes that tested below the tunnel. Torq plans to aggressively explore for high-grade gold – silver mineralization along the 1 km long corridor defined by quartz - alunite structures.

Underlying Porphyry Mineralization – Cerro Del Medio Target:
A two-hole drill program to test for porphyry mineralization beneath the epithermal mineralization encountered in the previous operator’s drilling was conducted from January 2012 to May 2012. The two holes were drilled from the northern side of the topographic high, defining the Cerro del Medio target area, and both intersected hundreds of metres of gold – copper – molybdenum porphyry-style mineralization. Drill hole CDM 03 intersected 925.7 m of 0.21 g/t gold, 0.27% copper and 82 ppm molybdenum, beneath the drilled gold mineralization from surface of 1.38 g/t gold over 24 m (drill hole SP-SC-24) by the previous operator in 1989. This demonstrates the potential for mineralization over one vertical kilometre from surface that remains open at depth and laterally. Table 4 below lists the intercepts from both drill holes.

Subsequent to the successful drill program testing for porphyry mineralization, ground-based Quantec Orion-3D induced polarization (IP) and magneto-telluric surveys were conducted in November - December of 2012 to characterize the geophysical signature of the underlying porphyry mineralization. The encountered porphyry mineralization was characterized by very low resistivity values, measuring between 3 – 6 ohm m, moderate chargeability values of less than 30 mrad and zones of very low magnetic susceptibility. Critically, the survey shows an area of 2 km x 2 km x 1 km of low resistivity values, which further demonstrates the potential to greatly expand the porphyry mineralization encountered. Torq plans to further explore the porphyry system by targeting structural corridors and potential feeder structures defined through the geophysical surveys.
High Priority Target Areas – Las Pircas – Pircas Norte:
To the east of the Cerro del Medio area, where the majority of the historical exploration work has been conducted, are the Las Pircas and Pircas Norte target areas. These targets are located approximately 2 – 3 km from the Caspiche deposit and are defined by areas of strong epithermal silicification alteration, which Torq’s technical team believes have significant potential for the discovery of underlying porphyry mineralization. This is supported by the low resistivity and moderate chargeability geophysical signatures, which start at depths as shallow as 250 m beneath the surface, as defined in the 2012 ground-based Quantec IP and magneto-telluric surveys. Both targets are characterized by resistivity lows of between 3 – 10 ohm m and moderate chargeability values of 30 – 40 mrad, which are consistent with the geophysical responses associated with porphyry mineralization under the Cerro del Medio target area. Together, these anomalies are approximately 1 km by 500 m, as defined by the resistivity data, but remain open at depth. Historical soils show a gold – silver – copper – molybdenum anomaly over the target areas coincident with the geophysical anomalies. The Las Pircas target area has only five shallow historical drill holes, totaling 476 m, that did not intersect the geophysical anomalies, leaving the target untested. The Pircas Norte target is under cover and has never been drill tested. Three rock grab samples taken from a small, isolated outcrop within the target reported a best result of 1.4 g/t gold and 0.5% copper associated with stockwork veining from a diorite porphyry exhibiting chlorite alteration after secondary biotite. Torq plans to aggressively explore the Las Pircas and Pircas Norte target areas with surficial programs to rapidly advance them to drill stage.
