You won't see any drilling results, if Coffey are actually on site they would firstly be mapping, plotting any historical drill/pit locations (remember these are quite old now and regrowth will have occurred over the 20 odd years since last activity and addressing environmental requirements and maybe marking out grids etc.
Luckily the mineralisation is widespread and has been located in the past, so it's not so much a new exploratory undertaking.
