Multiple High-Grade Intercepts 100m Below Current Open Pit
Rumble Resources Limited (ASX: RTR) believes it has uncovered potential for a high-grade gold underground operation with the discovery of broad zones of gold mineralisation within the current Western Queen South Deposit at its 100% owned Western Queen Project which lies some 100km NW of Mt Magnet within the Yalgoo mineral field of Western Australia.
Technical Director, Brett Keillor, said the final phase 3 drilling results focussed from the Western Queen South Deposit confirmed the company has intersected multiple high-grade gold shoots intercepted 100m below the current Western Queen South Open Pit.
“Defining multiple high-grade gold zones (in section) within the core of the main Western Queen South deposit highlights the potential of multiple high-grade shoots along strike and in section over the two km of open mineralisation defined by the three phases of drilling completed by Rumble,” Mr Keillor said.
“This augurs well for the potential of a substantial high-grade gold underground operation, especially with the Western Queen South deposit with respect to the competent amphibolite host which is amenable to stable ground conditions.”
Resource drilling at the Western Queen South gold deposit was designed to confirm and extend the known gold mineralisation associated with the current inferred and indicated resource of 823,000t @ 3.1 g/t for 83,000oz.
RC drilling was completed along strike (north and south), within the main higher-grade south plunging shoot and below the known mineralisation.
Multiple high-grade gold zones were intersected in hole WQRC188. Two high-grade shoots have developed in the hanging wall to the main south plunging zone.
Hole WQRC188 returned
- 5m @ 38.76 g/t Au from 193m (Hanging wall shoot)
- 3m @ 5.68 g/t Au from 210m (Hanging wall shoot) and
- 17m @ 5.7 g/t Au from 221m (Main south plunging zone)
The high-grade shoots defined by Rumble confirm down plunge/dip length continuity of known high-grade mineralisation from historic drilling.
Drilling by Rumble beneath the known mineralisation has highlighted the mineralisation is open directly below the main deposit as well as down plunge to the south
Drilling to the south of the Western Queen South Deposit and historic open pit has highlighted continuity of gold mineralisation (Western Queen Shear Zone) beneath a palaeo-drainage system (up to 35m deep).
Rumble will now move to finalise database compilation and associated resource estimation work for the multiple resource zones – Expected completion in February 2021.
It is also planning for follow up drilling of the high-grade shoots at Western Queen Central, Duke and the newly defined zones at Western Queen South to extend both resources and the potential for high-grade underground operations
