Target A

Target A consists of multiple high-grade Au-Ag quartz veins that have been defined within a 75 m wide zone of altered granite extending 600 m along strike.  Surface samples of vein material returned assays of up to: 8.53 g/t Au, 11.2 g/t Ag and 7.56 g/t Au, 16.8 g/t Ag.  Trenches completed over 300 m strike length of the vein array returned: 6.92 g/t Au over 1 m, 2.88 g/t over 2 m, and 1.4 2g/t Au over 12 m (incl 3.53 g/t Au over 3 m).  The vein array is contained within a broader zone of anomalous Pb defined as >100 ppm which is characteristic of the high-grade Au veins in the area.   Montero sampling within the area as shown in Figure 3.  Based on the assay results Montero will drill 6-8 holes for a total 1,200 m to test veins along 600 m of strike length.
