Rumble Resources Limited (ASX: RTR) has reported a high quality maiden Mineral Resource Estimate (MRE) for the Earaheedy Zn-Pb-Ag Project, 110km north-east of Wiluna, Western Australia.
The MRE occurs within the E69/3464 (75% Rumble / 25% Zenith Minerals Ltd (ASX: ZNC) and E69/3787 (100% Rumble) tenements.
Highlights
Maiden, pit constrained; Inferred Mineral Resource Estimate (MRE):
• 94Mt @3.1% Zn+Pb and 4.1g/t Ag (at a 2% Zn+Pb cutoff) constrained within optimized pit shells
• Contained metal of 2.2Mt zinc, 0.6Mt lead and 12.6Moz silver
• Represents one of the largest zinc sulphide discoveries globally in the last decade
Exceptional resource growth and Tier 1 scale potential
• The Chinook, Tonka and Navajoh deposits remain open downdip and along strike, demonstrating the potential for significant resource growth in the future
• Less than 35% of the targeted 45km, shallow and flat lying, mineralized Unconformity Unit that hosts the potentially open pittable Zn-Pb resources has been effectively drill tested
• Recently reported gravity survey has defined numerous higher grade feeder structure targets along strike to the northwest, and southeast within RTR’s 100% EL’s
• Significant potential to discover high grade MVT & structurally controlled deposits in the fertile underlying carbonate formations which are yet to be tested
Excellent metallurgical results
• Previously reported sighter flotation metallurgical results have highlighted the potential of a clean highly marketable bulk concentrate with Zn recoveries up to 90%, grades to 64% Zn+Pb, and a low capital/ operational cost process flowsheet
Project Optionality
• The pit constrained MRE hosts a 41Mt higher-grade component above a 3% Zn+Pb cut-off grade, and a very large 462Mt component above 0.5% Zn+Pb cut-off grade that has the potential to be upgraded through beneficiation, providing the Earaheedy Project with significant optionality for future development
“This exceptional resource estimate is a major milestone for Rumble, confirming the Earaheedy Project as one of the largest zinc sulphide discoveries globally over the last decade,” Managing Director, Shane Sikora, said.
“Achieving a maiden JORC compliant Mineral Resource Estimate of this size and significance in 24 months post discovery is a tremendous effort by the technical team and especially Brett Keillor. Myself and the team are really excited as we believe we have only scratched the surface on the discovery front, and can’t wait to see the drill rigs turning again next month.”
