NEVADA – Corvus Gold of Vancouver has expanded the high grade stockwork zones thanks to assays from seven holes drilled through the Yellowjacket vein system at the Bullfrog gold project 5 km northwest of Beatty. Completed results demonstrate that the combined near surface, high grade, bulk tonnage, vein and stockwork zones are consistently 20 to 50 metres wide. Average grades range from 1 to 7 g/t Au and 14 to 32 g/t Ag.
Corvus says it has confirmed the continuity of the Yellowjacket vein system over a strike length of 650 metres to a nominal depth of 120 metres. The system was drilled 50 metres down dip late this season, and it intersected a board zone of stockwork veining as well as an 8 metre thick banded vein at 170 metres vertical depth. The core had visible gold and silver. The system is open to the north, perhaps at depth, and has yet to be explored to the south.
Drilling also intersected a different style of disseminated and veined mineralization at depth, said the company. Hole NB-13-357 returned a promising 0.94 g/t Au over 42 metres in this type of mineralization.
The continuity of mineralization in the main stockwork is variable, with hanging wall thicknesses ranging from 7 to 50 metres and footwall thicknesses ranging from 4 to 30 metres. Average grades range from 0.4 to 15 g/t Au.
