This magnetics image has the outline of the mining licence (ML) area M63/671. (The Callisto well locations are not up to date).

Brad has said a number of times that the ultramafic host shows up well on the magnetics and hence the interest in going N up the "prospective contact zone" shown. He initially said they would go E, find the extremity of the mineralisation, then follow the most highly mineralised part N. I've been interested to see whether or not they go over the ML border as they go E. A significant chunk of what they label "Mt Thirsty Sill" is outside the ML but also, as the image shows, has a strong magnetic response.

Note that our neighbours to the S plan to drill in areas that do not have a strong magnetic response, apparently based on perceived continuity of the chert layer and target mineralisation being in the contact zone above it. Interesting times.
