Assay Results from the Domo Zone
The Domo zone is uphill from the Tesoros 1 zone approximately 1 kilometre to the northwest. The exploration target is a large silica cap structure which, in exposure, is at least 250 meters long, 35 meters thick and 100 meters wide. The structure is completely exposed on the northern flank of the mountain with no overburden. Channel samples up to three meters long were taken from a number of artesanal tunnels which extend from 2 to 30 meters into the structure. The random placement of the tunnels covered the entire exposed thickness of the structure. A total of 59 samples were collected in the Domo tunnels within the disseminated silica cap. Of these 20% had assay values greater than 20 g/t of gold and 15% assayed greater than 200 g/t silver.
The following samples returned assays greater than 20 g/t of gold (Au) and 200 g/t silver (Ag).

Assay Results from the Callanquitas Zone
The Callanquitas zone is a highly fractured boxwork type structure on the northwest nose of the dome approximately 2 kilometers from the Tesoros 1 area. Faulting has resulted in significant erosion of this area of the mountain. Short channel samples were taken from 7 tunnels in the extremities of the zone. Of the 17 samples taken, 47% resulted in grades of over 4 grams per tonne of gold and 24% had grades greater than 100 grams per tonne of silver.
The following samples returned assays of greater than 4 g/t of gold (Au) and 100 g/t of silver (Ag).

Assay Results from the Portachuelo and Carmen Alto Zones
These two zones are located in an argillized porphyry intrusive with an associated boxwork structure at the bottom of the southern flank of the dome. Channel samples were taken from small tunnels and rock exposures. Of the 24 samples taken, 29% resulted in grades of over 2 grams per tonne of gold and 17% had grades greater than 100 grams per tonne of silver.
The following samples returned assays of greater than 2 g/t of gold (Au) and 100 g/t of silver (Ag).

Drill Results
The Company also announces the first drill hole results for the Igor property. The Company has drilled over 400 meters of a projected 2500 meter program and has results for the first two holes. Holes 2a and 2b were both drilled from the same elevation of 3151 to depths of 105.0 and 98.4 meters respectively and assay results for the important sections of each hole are shown on the table below. Overall core recovery for the two holes was 91% for hole 2a and 84% for hole 2b. The Company reports that drill results thus far confirm the existence of a significant, disseminated breccia system. When corrected for hole direction (inclination and azimuth) a true width for the breccia zone in the area of these two holes is calculated to be 35 meters which confirms the information provided by previous tunnel mapping and sampling.
Significant assay results from holes 2a and 2b:
Hole Sampled Azimuth Inclination From To Au Assay Ag Assay m m m g/t g/t 2a 108 90.0 -45.0 2 8 2.6 17.1 10 16 1.1 46.3 Overall average 2 16 1.5 30.2
2b 86 310 -45.0 10 16 0.9 59.0 20 24 0.6 16.5 Overall average 10 24 0.6 45.4
Three other holes were also drilled (10, 12a and 12b), hole 10 was not completed due to lost rods prior to encountering mineralized zone and holes 12a and 12b had core recovery less than 40% resulting in unacceptable samples for assaying. The Company is taking steps to mitigate against low penetration rates due to the extremely hard rocks encountered and the poor core recovery in highly fractured zones. As more drilling experience is gained, field experimentation is increasing both indices to acceptable levels.
Sampling Methodology
The channel samples were taken by chipping the rock to a depth of at least a couple of centimetres for a continuous sample length. The rock chips are collected on a plastic drop sheet and then placed in a sealed sample bag. Cores taken from the diamond drill rig are stored in plastic core boxes and transported to the camp site for detailed logging. When logged the core is sent from the project site to the Company's secured site in Trujillo for splitting with a diamond saw. One half of the split core is then sent to SGS Laboratories in two meter sample lengths. The Company's independent qualified person Mr. Randy Henkle of Henkle and Associates has completed a chain of custody review to ensure the integrity of all sample data.
Assaying Methodology
The samples are analyzed by SGS Laboratories in Lima by atomic absorption for silver and a 30 gram fire assay technique for the gold analysis. Samples which exceeded the detection limits were re-assayed using a gravimetric fire assay technique. Blank samples are randomly inserted into the sample runs and referee assays are done on randomly selected samples to confirm the SGS results. The specific procedures used by the lab can be found in the Company's 43-101 report on the Igor property.
