Down-hole electromagnetic exploration on five holes drilled by Desert Metals have indicated that previously identified very high conductance bodies have yet to be intersected by drilling.
While holes DRC003 to DRC007 at Dingo Pass intersected metamorphosed mafic intrusions with traces of disseminated copper and nickel bearing sulphides, these were not present in sufficient quantities to explain the anomalies.
Modelling of DHEM data from these holes confirms the presence of the very high conductance bodies (up to 30,000 Siemens), which were first defined by airborne and then ground EM surveys, and suggests that they are off-hole from the initial reverse circulation drilling.
Desert Metals (ASX:DM1) has mobilised a RC rig to site and will start drilling later this week in a bid to test the bodies.
Diamond drilling is scheduled to begin later this month.
From its initial drilling, the company has inferred that the targeted host intrusions were deformed and metamorphosed.
In other nickel provinces where this is the case, such as the Thomson Belt in Manitoba, Canada, the sulphides are often reworked into fold hinges and other structurally complex positions.
This makes their associated conductance difficult to model and would explain the relative lack of success in intersecting the targeted conductors on the first pass.
