Montero recently completed the purchase of a 100 % interest in a Chilean corporation (“ChileCo”) that holds the

mining rights to the Isabella Gold Project. The most recent sampling program was carried out to verify types and

styles of mineralization and confirm prior assay results. The program consisted of chip sampling of selected exposed

quartz veins previously sampled by ChileCo. Based on a positive review of the Montero and previous sample assay

results and field observations, Montero intends to complete an initial drill program on 4 high grade Au-Ag priority

vein targets; Target Areas A, B, C & D are permitted for drilling (see Figure 2).
