| | QUALITY ASSURANCE & CONTROL
Drilling, sampling and assaying on the San Anton Property and the Cerro del Gallo deposit is carried out in a manner consistent with good industry standards and methodology. Sample collection and assaying is systematic and precise in accordance with strict procedural controls. Readers are invited to review the relevant chapters of the NI 43-101 “Technical Report on the Cerro del Gallo deposit”, which comprehensively details the relevant protocols and procedures. | | |

| | Drilling | | | Drilling at Cerro del Gallo consists of either Reverse Circulation (RC) drill holes (diameter 4 ¾”-5 ½”), which produce ground rock chip samples of fine to medium granularity, or Diamond Drill Hole (DDH) of HQ size, which produce cylindrical rock cores with a diameter of 63.5mm. The drill hole direction was determined based on a requirement to intersect all identified dominant quartz-sulphide vein sets at the highest angle possible. Fracturing and veining is intense at Cerro del Gallo and it is assumed that at least some of the Cu-Au-Ag mineralization is spatially, temporally and genetically associated with vein and brittle fracture sets. This assumption is supported, in part, by various orientations of structures and veins observed in old workings on Cerro del Gallo.Evaluation of the Cerro del Gallo porphyry deposit is based on a nominal grid of 50 m spaced sections oriented 030º/210º TN and 50 m spaced drill collars with predominantly 60º inclined drilling for diamond core and reverse circulation drill holes along section planes. Some infill drilling of 60º inclined drill holes on a 50 m and 25 m line spacing and 25 m collar separation has also been completed in the northeast area. Drill holes are drilled along sections in both the 030º and 210º directions.Drilling has been completed over an area of approximately 1500 m in a north-south direction and 1400 m in an east-west direction centered on the peak of Cerro del Gallo. Drill holes have been drilled to a maximum depth of 700 m below surface, with the large majority of holes drilled to a depth of less than 300 m below surface due to the limited capabilities of the drilling equipment. | | |

| | Sampling | | | Reverse Circulation (RC) samples were collected by three samplers under direct supervision of a geologist experienced with RC drilling and sampling techniques who was on-site at all times while drilling and sampling was in progress. Sampling procedures and sample numbers were constantly checked and monitored by the rig geologist and senior sampler. Sample depths were cross-checked with the driller and/or offsider at regular intervals, commonly at a rod change, and hole depth validated against the corresponding logged depth recorded by the geologist on the log sheet. Sample numbers were also checked by the senior sampler against the geologist’s log sheet. RC Samples were collected continuously at 5 foot (1.52m) intervals from the drill collar at surface to the bottom of the hole. RC Samples are collected in a manner consistent with good industry standards and methodology, and can be considered representative of the sub-surface rock formations and underlying mineralization.Most of the diamond core recovered is HQ (63.5 mm) size and on rare occasions when a size reduction is required due to fractured ground conditions NQ (47.6 mm) is recovered. The core is re-configured to its original in situ state to form a continuous cylinder. The core is firstly marked longitudinally with a felt tipped pen and then marked at 1.0 m intervals for sampling for assay. The 1.0 m sample intervals are sawn transversely using a Target core saw with a 10” diameter diamond studded saw blade. The core is then sawn longitudinally in half. Only the “south side” of the core is sampled for assay, preserving a continuous longitudinal section of core for further investigation (the “north side”). The half sawn “south side” core is then progressively bagged for assay in 1.0 m intervals. Each 1 m sample interval is marked on the inside of the core tray. | | |

| | Assaying | | | | SGS Canada Inc. Minerals Services in Toronto, Ontario, Canada was the primary laboratory used for routine element analysis of drill, rock-chip, soil, and stream sediment samples from the San Antón Property. The SGS-Toronto facility is ISO 9002 registered, and ISO/IEC 17025 accredited for Specific Tests under the Standards Council of Canada (SCC) No.456. SGS Canada Inc. Mineral Services is a member of the world wide SGS Group.SGS has a sample preparation facility in Durango (Durango State), Mexico that is within a one day drive of the San Antón Property. Sample pulps were prepared in the Durango sample preparation facility prior to air-freight to the Toronto laboratory in Canada for analysis. Durango is located approximately 600 km northwest of San Antón. | | |
