The 2,500-metre program will test the grade, depth potential and width of the gold-bearing Estrella epithermal quartz breccia zone, which has a strike length of about 1.5 km.
Old workings exist along a northwesterly trending shear zone, which is 12-30 metres wide. The shear zone is defined by a quartz and amethyst stockwork surrounded by a brecciated and silicified alteration zone with pyrite, hematite and minor manganese oxides.
The distribution and type of alteration seen at Estrella suggest that the outcropping mineralized zone is the top of an epithermal gold-silver system.
Underground mining was carried out in the 1930s, when grades of 50-100 grams gold per tonne were reported. During this phase, numerous quartz-breccia veins were encountered.
The underground workings are 80 metres below the surface of the Estrella Ridge, where two geochemical trends have been defined.
The eastern anomaly covers the stockwork zone and trends northwesterly for 1 km, with an indicated width of 100-150 metres. The core of the anomaly exhibits gold values ranging from 500 to 10,000 parts per billion.
Five hundred metres to the west is the second anomaly, which trends northeasterly and appears to merge with the eastern anomaly to the north. It has been traced for a distance of 500 metres and is open to the south.
Recent exploration has extended the northern portion of the Estrella zone by about 1,000 metres to the northwest.
