Rock Geochemistry


• 1500m long, up to 1.5m wide veinstriking north-south.

• 40m long tunnel with two levels atMina San Pedro. Competent veinwithin tunnel.

• Vein is finely banded, colloformchalcedonic quartz withpseudomorphs of bladed calcite andtransparent to amethyst drusy quartz.Rare hematite bands.

• Rock chips up to 19g/t Au and 50g/tAg, anomalous in Ba and Sb.

• Visible gold in hand samples.

• Over 900m elevation difference between lowest base metal-rich veins and higher-level veins with boiling textures.

• Geochemical zonation with elevation.

• Significant target area beneath veins in boiling zone.
