Rumble Resources Ltd (ASX:RTR) (FRA:20Z) has started a 2,500-metre reverse circulation (RC) drilling program at Earaheedy Zinc-Lead-Silver Project in Western Australia targeting large tonnage, flat-lying, near-surface sandstone-hosted zinc-lead deposits.
Drilling will first focus on the Chinook prospect where step-out drilling is set to test zinc-lead strike potential before moving on to the Magazine prospect to define a drill section and step-out to test strike potential, particularly the inferred higher-grade zinc-lead identified in sandstone channels and facies zones.
The program is set to take around three weeks with assay results to follow.
Large-scale deposit potential
At Chinook, higher-grade zinc-lead has been confirmed over 200 metres horizontal width and up to 12 metres vertical of true thickness (within 41 metres of a zinc-lead broad zone).
Magazine and Chinook are 10.5 kilometres apart with the zinc-lead-silver mineralisation completely open.
Plans to test exploration target
The project covers an area of more than 40 kilometres of sandstone unconformity prospective strike, which remains untested.
Rumble’s zinc-lead exploration target at the Earaheedy Project is between 40 to 100 million tonnes at a grade ranging between 3.5% zinc-lead to 4.5% zinc-lead.
The company intends to test the exploration target with drilling and this further drilling is expected to extend over about 12 months.
