Arrow last month recorded the best intersection to date from the Strickland Gold Project in Western Australia - 56 metres at 0.8 g/t gold from surface to the end-of-hole.
This came from the maiden aircore drilling of the T6 prospect, with bedrock gold mineralisation intersected.
A total of 394 holes for 7,937 metres were drilled on a 400x80 metre grid.
Four bedrock gold prospects have been identified from 1.5 to 3.5 kilometres in strike length, with several prospects remaining open along mineralised structures.
