DMC has narrowed down its exploration focus at the Ravensthorpe nickel project down to three high priority electromagnetic conductivity targets outlined by ground surveys.

The anomalies – identified by low frequency moving-loop EM (MLEM) and fixed-loop EM (FLEM) surveys following up on the RAV 9 and RAV 11 conductive targets – are associated with magnetic anomalies, surficial geology and geochemistry.

DMC Mining (ASX:DMM) says the anomalies are interpreted to represent buried komatiite lava sequences and that planning is now underway to drill test the targets as soon as feasible.

“The compelling RAV 9 and RAV 11 conductive targets are the culmination of systematic and methodical exploration over the past 12 months and we are highly encouraged to have identified them in a premier and productive nickel endowment region of WA,” executive chairman David Sumich said.

“Our exploration team is currently finalising the drill planning process and we look forward to drilling as soon as possible.”

New EM targets

The three targets – one at RAV 9 and two at RAV 11 – were identified by ground EM surveys.

Surface geochemistry conducted over the target areas returned high values for nickel and cobalt consistent with buried ultramafic lithologies but remain inconclusive as to sulphide potential.

However, nickel sulphide systems are often closed geochemically and entirely contained within the target ultramafic host with little to no wall rock leakage or “halo” of the target metals.

Such buried sulphide systems may be geochemically blind to surface sampling and not return anomalous metal values in geochemical data unless they are intersected by the weathering profile.

DMC plans to test the targets with diamond drilling once appropriate permitting has been completed.
