Rumble Resources Ltd (ASX:RTR) has found high-grade tungsten (scheelite) mineralisation through diamond drilling at its Western Queen South deposit near Mt Magnet in Western Australia, with this occurring within a wider gold system of the Western Queen project.
One drill hole – WQDD013 – returned intercepts such as 4 metres at 4.58% tungsten trioxide (WO3) and 0.72 grams per tonne (g/t) of gold from 174.85m; including 2.05 metres at 8.71% WO3, 1.38 g/t gold from 176.85m; and 0.65 metres at 18.35% WO3, 2.97 g/t gold from 176.85 metres.
The company also outlined a strong and continuous anomaly for the mineral over 2 kilometres through drillhole XRF data, which parallels Western Queen’s shear and known mineralisation there.
Tungsten is also present at surface – occurring at widths of up to 20 metres – between the Western Queen South and Western Queen Central open pits.
Rumble is looking ahead to the release of wet assays of the mineral taken from selected pulps following reverse circulation (RC) drilling, with these already submitted but yet to be reported.
Emphasising the importance of the WQDD013 hole, diamond core taken from it has been subjected to ultraviolet scanning, with this highlighting scheelite within altered mafic, and revealing that the mineralisation is comprised of scheelite-pyroxene +/- magnetite+/-gold skarn zones 2.1 million tonnes at 2.42 g/t gold for 163,200 ounces.
Rumble’s Managing Director and CEO Peter Harold said the tungsten discovery had not been the focus of recent diamond drilling, but was an important discovery nonetheless.
“The discovery of the very high-grade tungsten at Western Queen is an unexpected bonus for us from the recent drilling which was targeting extensions to the high-grade gold
lodes,” he said.
“While it is very early days the grades of the intersections are exceptional and well above the grades of other tungsten resources globally. We are now waiting with trepidation for the results from the 2021 drill pulps.
“This discovery shows the huge optionality of the Rumble tenements and the ability of our highly experienced exploration team to make new discoveries.”
The market seemed pleased with the news, and at 12:10 AEST, Rumble shares were trading at 3.6 cents, a rise of 12.5% since the market opened.
