Zenith Minerals’ (ASX: ZNC) joint venture partner Rumble Resources (ASX: RTR) has begun drilling the recently discovered Kalitan feeder zone within the Earaheedy base metal project in Western Australia.
The Kalitan feeder zone discovery was announced late last month, and it lies below the Chinook zinc-lead target that is about 4.1km long and 1.9km wide and first uncovered in April last year.
Drilling at the feeder zone has defined mineralisation over 2.3km of strike.
The best intercept from this zone was 51m at 4.76% zinc and lead, plus 5.81 grams per tonne silver from 82m, including 20m at 8.78% zinc and lead, and11.7g/t silver, including 8m at 14.61% zinc and lead, plus 17.7g/t silver.
According to Zenith, which owns 25% of Earaheedy, geological evidence gather to-date supports the potential for the further large-scale copper-zinc-lead-silver deposits to be identified at the project.
Since discovering Chinook last year, Rumble has been undertaking a 50,000m scoping drill program across Earaheedy.
Rumble noted that drilling at the project is rapidly uncovering a “world-class scale zinc-lead-silver-copper base metal system”.
More than 50% of the assays from the 50,000m program remain outstanding.
With drilling restarting at Earaheedy, the Kalitan feeder zone will be the focus.
Zenith chief executive officer Mick Clifford said he was “very pleased” that Rumble was moving quickly to “aggressively” scope out the scale of the mineralisation identified at the Kalitan feeder zone.
Drilling will also be carried out to scope size and grade of Chinook, Tonka, Magazine and Navajoh prospects to improve confidence and define the limits of mineralisation.
“The planned work programs will ensure there is continuing ongoing news flow, as the partners work to unlock the potential of the four exciting zinc-lead discoveries made in 2021 within the joint venture project area,” Mr Clifford added.
In parallel, metallurgical studies will be undertaken with initial sighter test work underway.
As well as its interest in Earaheedy, Zenith controls 100km of prospective strike in the basin.
