Warriedar Resources has recorded depth and strike extensions at its Silverstone deposits after receiving assays from reverse-circulation (RC) drilling at the company’s Golden Range project in WA’s Murchison region.
The Ricciardo campaign consisted of 17 holes through 3148m, with significant results showing a 7m intercept going 4.48 grams per tonne gold from 251m, including a 1m hit at an outstanding 24g/t gold from 256m.
Additional highlights show another 7m section grading 1.45g/t gold from 214m, including 2m reading 4.06g/t gold from 219m. Another 18m section read 1.21g/t gold from 183m, containing a 5m segment going 2.1g/t gold from 193m.
The drill program was designed to assess depth and strike extensions to the company’s existing cluster of deposits dubbed Eastern Creek, Silverstone and Copse-Ardmore. Warriedar says its mineral resource for the deposits sit at about 476,000 ounces, with all three remaining open.
Historic open pits demonstrate previous mining of the deposits for oxide gold, with the company targeting fresh rock gold below and along strike from previous workings.
The world-class Golden Grove volcanogenic massive sulphide deposits are just 3km from Warriedar’s Golden Range leases and the mineralisation host-rock sequence extends into the company’s ground. The Golden Range 800,000-tonne per annum processing plant was placed on care and maintenance in 2019 and the infrastructure provides Warriedar with the potential for an accelerated, low-capital-cost pathway to gold production.
With previous exploration focused on shallow oxide deposits, management sees a big opportunity in delineating primary gold deposits below existing former oxide gold mines.
Historic results from the area around the old pits returned significant results, including 13m going 16.56g/t gold from 18m, a 38m hit grading 3.84g/t gold from 140m and 12m at 11.02g/t gold from 58m. The company says its greater Golden Range project has a JORC resource of 945,000 ounces of gold that includes the three deposits around Silverstone.
The latest drilling has extended the Silverstone North deposit at depth, while a single hole returned two significant intercepts at depth below the existing deposit. The company says it proves that the mineralisation extends to at least 180m below surface and remains open.
Warriedar adds that the recent program has provided confidence that the mineralisation at the southern end of the Ardmore-Copse pit extends to at least 480m vertical depth below surface.
While more drilling is required to shore up the continuity of the deposit and to build towards future resource modelling, the area is now set to be aggressively followed-up as part of the next quarter’s drilling program. Initial metallurgical testwork is also planned for later this year to assess the optimal potential flowsheet for the high-grade gold mineralisation.
