2007 Exploration Program

In June 2007, the Company completed a phase-one drill program that totaled 660 metres in six NQ core holes. All drill holes intercepted significant zones of mineralized breccia, with highlights including 33.5 metres of 179 g/t silver, 22.8 metres of 94.7 g/t silver and 56.4 metres of 84.5 g/t silver, with associated lead and zinc values.

2007 drill results are as follows:

It is important to note that DDH-07-03 was collared in overlying volcanics and intersected the mineralized breccia where projected by surface mapping, reinforcing the concept that the volcanics cap a larger breccia body.

Property wide reconnaissance of the project was completed 2007, with additional targets identified. Early in the year, a mapping, sampling and trenching program was completed over the northern half of the property resulting in the discovery of the La Estrella, Los Alisos and EL Portrero Zones.

The La Estrella Zone is located two kilometres to the southwest of the Reventon Breccia. In February 2007, 24samples taken from the zone average 0.825 g/t gold and 385 g/t silver over sample widths from .85 to 5 metres. An additional 7 samples were taken in April and extended what appears to be a high-grade vein system to a defined strike length of at least 180 meters. It remains open in both directions. Results from the most recent samples are as follows:

The Los Alisos Zone lies in close proximity to the Reventon Breccia, approximately 500 metres to the south. Previous excavated trenches reported values of 88 g/t silver over 15 metres within a broader zone of anomalous silver values. The Los Alisos and Reventon Breccia zones appear to be geologically similar in that they have a comparable geochemical signature and both occur in dorite porphyry. The area between the two zones is covered by post-mineral volcanics and agglomerate; however the Los Alisos Zone may be open to the north and the east.

The El Portrero Zone is located approximately one kilometer northeast of the Reventon Breccia, and contains dozens of prospects and small mine workings over an area of approximately 150 by 225 metres. The zone is being explorated as a potential bulk mineable silver target with vein, stockwork and disseminated mineralization occurring in silicified diorite porphyry. A total of 61 samples taken from the zone average 23 g/t silver over widths ranging from 1.5 to 7 metres.
