Rumble Resources Ltd (ASX:RTR, OTC:RTRFF) has completed a significant diamond drilling campaign at the emerging world-class Earaheedy zinc-lead-silver project in Western Australia, aimed at supplying core for essential metallurgical beneficiation trials later this quarter.
The drilling campaign was focused on Chinook, the largest of the pit-constrained inferred sulphide resource areas, where 10 diamond holes for 1,462.7 metres were completed within E69/3464 and E69/3787 to yield an estimated two tonnes of mineralised drill core samples.
Drill core has been logged and photographed and the selected intervals have arrived in Perth for assay analysis and metallurgical testing.
The Chinook deposit has a mineral resource estimate of 63 million tonnes at 3.0% zinc+lead and 4.6 g/t silver, at a 2% zinc+lead cut-off.

Beneficiation test programs have been used in the mining industry for years and are useful to assess the potential to upgrade lower-grade zinc-lead mineralisation.
This low-cost and efficient processing technique is highly effective in modified Mississippi Valley Type (MVT) environments such as Earaheedy to provide exploration companies with more development options.
RTR is on track to commence the beneficiation testing and flowsheet optimisation in the March quarter, with results to be reported in the first half of the year.
