Ann: Chisel Prospectivity Enhanced Following Gravity Survey, page-10

This is not my core expertise by a long way, but it absolutely does not look like a discrete or isolated anomaly!  This anomaly is clearly open to the north and northeast.

To me it looks to be connected to another body, structurally linked by the secondary fault.  And while this study may have located the primary deposit with a smaller secondary deposit just off the northeastern edge the concave shape of the border and the steepness of the density gradient strongly imply that whatever it is out there it could be very large and very dense.

I believe that the gravitational survey needs to be extended before we start drilling this area.
