Nickel Copper Sulphides confirmed in historical drilling at the Rocky Gully Ni-Cu Project, Albany Fraser Belt, WA
-
Review of historical drilling confirms anomalous nickel copper sulphides at the M19 and M20 prospects, within the Rocky Gully Ni-Cu Project, WA.
-
Peak intercept of 12m at 0.71% Ni and 0.01% Cu at the M20 prospect represents a similar regolith expression to the Nova-Bollinger discovery signature.
-
Lithology interpreted to be magmatic differentiation of the ultramafic bodies.
-
Petrography confirmed pentlandite (nickel sulphide) chalcopyrite (copper sulphide).
-
M19 and M20 are 2 of 10 targets being progressed at Rocky Gully, with a program of works currently being organised to test for Nova-style magmatic Nickel Copper deposits.
PLD Corporation Limited (ASX:PLD) (“PLD” or “the Company”) is pleased to announce the confirmation of the presence of Ni-Cu sulphides from historical drilling, at the Rocky Gully Ni-Cu Project, located in the Albany Fraser Belt, WA (Figure 1 and 2).
Historical drilling identified Ni-Cu anomalism in RAB drilling over a 600 metre north south traverse at the M20 prospect. Evaluation of the historic drill hole database at M20 has identified primary Ni-Cu enrichment within five (5) key intersections to a depth of only 60m (Table 1), with the peak intercept of 12m at 0.71% Ni and 0.01% Cu (Figure 3)(Heron Resources Limited ASX release 22 October 2012). All holes ended in Ni-Cu enrichment, with the Ni-Cu grade increasing in each hole moving north along of the traverse, towards the recently identified EM Conductor.
Drilling intersected weathered coarse grained metamorphosed ultramafic rocks, and gabbros. This suggests the potential for magmatic differentiation having taken place. Primary sulphides, pentlandite and chalcopyrite were observed in drill chips at the M20 prospect and shown in figure 4 being a photo micrograph from this intercept. (Heron Resources Limited ASX release 22 October 2012)
The Nova Nickel Copper discovery RAB drilling expression (Sirius Resources NL ASX release 10 May 2012) is characterised by similar anomalous nickel and copper geochemistry, where a peak intercept of 9m at 0.52% Ni and 0.05% Cu preceded a discovery hole into fresh bedrock of 4m at 3.8% Ni and 1.42% Cu (Sirius Resources NL ASX release 26 July 2012).
Deeper drilling into fresh bedrock at the M19 and M20 prospects to test for magmatic nickel copper mineralisation is being evaluated, along with a regional geochemistry and geophysical programs on the remaining eight (8) priority targets, which will form the basis of the Company’s next phase of exploration.
Commenting on the M19 and M20 prospect, Managing Director Matthew Gauci said:
“The results confirm the prospectivity at Rocky Gully to host Magmatic Nickel Copper Sulphide deposits. Phase I of exploration has identified appropriate geological, geochemical, geophysical signatures. Phase II will now commence to evaluate drilling at the M19 and M20 prospects at Rocky Gully Central, and progress all eight (8) other targets at Rocky Gully East and West.”
