Rumble Resources Ltd (ASX:RTR, OTC:RTRFF) has confirmed the Mato prospect as a significant new zinc-lead sulphide discovery at its Earaheedy Project, north of Wiluna in Western Australia.
The Mato discovery, announced earlier this month, has the hallmarks of a large mineralising system that lends further support to Earaheedy developing into a world class base metal camp and could enhance project economics.
Latest results support discovery
Rumble reports that assay results from the remaining six reverse circulation (RC) drill holes at the newly defined Mato prospect complement the initial discovery and demonstrate potential to substantially increase the existing pit-constrained inferred mineral resource estimate of 94 million tonnes at 3.1% zinc+lead, using a 2% zinc+lead cut-off, at the project.
These latest results include 29 metres grading 3.12% zinc and lead from 174 metres deep, including 14 metres at 5.04% zinc and lead from 183 metres, with high-grade zones of 4 metres at 10.16% zinc and lead.
The results at Mato all come from a single 800 metre long drill traverse — the same 800 metre section where the discovery RC hole returned high grade zinc-lead mineralisation of 16 metres at 5.09% zinc and lead from 153 metres deep.
The strike of this mineralisation at the highly prospective Mato Mineralisation Corridor (formerly Sweetwater Trend) has now been defined over 10 kilometres.
Looking ahead
With heritage approval granted to allow extensional RC drilling, Rumble’s next steps at Mato include drilling to define shallow and strike-extended sulphide mineralisation, along with testing potential structural repetition of the host Navajoh Unconformity Unit to the south.
