Rumble intersects sulphide mineralisation on Fraser Range
THE DRILL SERGEANT: Rumble Resources (ASX: RTR) has encountered disseminated sulphides during a maiden drill program being undertaken at the company’s Big Red project in the Fraser Range of Western Australia targeting nickel-copper sulphide mineralisation.
Rumble has completed four Mud Rotary/Diamond drill holes with the program, which was designed to test a two kilometre EM conductor the company had identified from a high powered ground EM survey.
As previously reported the first hole reached 240m but was abandoned through difficult drilling conditions.
However, all three subsequent holes reached target depth, intersecting sulphide zones within gabbros of the Fraser Range Complex.
The company described the sulphide zones to be of considerable widths and has interpreted this to indicate the conductor to be a substantial mineralised system.
Hole BRDD002 intersected two zones of gabbro, the first from 359.7m to 374.1m contained 14.4m of disseminated sulphides dominated by pyrrhotite and chalcopyrite (copper) towards a mylonitic faulted contact.
A second zone was intersected from 386.2m to 399.9m, which also intersected 13.7m of sulphides in layered gabbro with similar sulphides towards a mylonitic lower contact zone.
BRDD003 was drilled some 200m to the North of hole BRDD002 with a thin zone of disseminated pyrrhotite and chalcopyrite from 339.3m to 340.3m along with a thin gabbro unit from 360.7 to 362.5m.
Rumble explained this hole is closer to the original Teck hole which contained gabbro with only slightly elevated sulphur and copper.
BRDD004 was then drilled 300m to the south of BRDD002 which intersected the broadest gabbro unit.
It intersected two units with the upper unit from 183.6m to 190.6m containing disseminated pyrrhotite and chalcopyrite sulphides.
A much broader zone was identified from 245.6m to 284.6m containing similar disseminated to blebby sulphides near the lower contact.
The drill core was logged onsite and is being transported to ALS for cutting, assaying and petrology.
“Intersecting copper sulphides within Fraser Range gabbro units has enhanced the prospectivity of the Big Red project for both nickel and copper massive sulphides to be present,” Rumble Resources CEO Shane Sikora said in the company’s announcement to the Australian Securities Exchange.
“These sulphide zones are of considerable widths and indicate the conductor to be within a large mineralised system.
“The three drill holes have only tested a small section of the two kilometre bedrock conductor highlighting the area’s potential.
“We are fast tracking a downhole EM program targeting areas that represent the highest conductance which may represent massive sulphide accumulations.
“An off hole conductor would represent a compelling target for the next phase of drilling.”
