Rumble Resources Ltd’s (ASX:RTR) (FRA:20Z) final drill assay results from reverse circulation drilling at Barker Well Prospect of Braeside project in Western Australia's Pilbara region have revealed multiple high-grade lead breccia zones from surface and over 800 metres of strike.
Of significance is that the drilling is shallow at an average 50 metres depth, with mineralisation open in all directions.
Results include 4 metres at 18.63% lead, 1.72% zinc and 11.7 g/t silver from 17 metres and 3 metres at 13.93% lead, 0.54% zinc and 10.1 g/t silver from 29 metres.
These results complement the strong results earlier this week at Camel Hump Prospect, also on the Braeside Project, where wide zones of copper oxide mineralisation with zinc and lead hosted in volcaniclastics were discovered showcasing all the hallmarks of a new VMS (volcanogenic massive sulphide) province.
Both discoveries highlight the potential for camp scale 'clusters' of high-grade base metal deposits with 45 high order untested targets generated all capable of discoveries.
Shares are 12.5 per cent higher at 13.5 cents in early trading.
Barker Well discovery
A total of 52 RC drill holes for 2,290 metres tested three main areas over a strike of 800 metres at Barker Well.
The discovery of high-grade galena mineralisation associated with breccia zones/pipes has upgraded Barker Well as having potential for economic lead-zinc-silver open cut/underground deposits.
High-grade galena mineralisation has developed as semi-massive ‘pipe-like’ zones with generally steep south plunging pyrite – silica breccias within pervasive chloritised altered flat-lying andesitic basalts and associated volcaniclastics.
Galena (dominant mineral) and minor sphalerite is pervasive within the chlorite altered host as sulphide veinlets and disseminated zones.
The width of the pervasive alteration is significant with up to 40 metres wide zones grading 1% lead (about 30 metres true width).
Orientation IP is planned to test the north and south breccia zones at Barker Well. Silica-pyrite-galena breccia zones within a shallow weathered environment and hosted in predominantly andesitic basalts, in principle, would be conductive to a resistivity/chargeability survey.
The IP survey will aid in targeting deeper high-grade mineralisation positions for RC and diamond core drilling.
This will further scope out the size potential for multiple breccia zones.
Rumble holds a significant holding in the Fortescue and Paterson provinces of the East Pilbara Region, Western Australia, with more than 2,968 square kilometres of highly prospective tenure known for its large-scale Tier-1 discoveries which continue to be made.
The Braeside Project area comprises 673 square kilometres. Contiguous to east of the Braeside Project is the Warroo Project comprising 970 square kilometres and the Lamil joint venture project with an area of 1,325 square kilometres.
Rumble acquired the Braeside Project in April 2017.
The project hosts historic high-grade lead dominant small-scale prospects and diggings including the high-grade Ragged Hills mine that produced high-grade lead, zinc and silver up until 1959.
Prior to Rumble’s acquisition, no systematic modern exploration had been completed at Braeside.
The first phase of systematic exploration commenced in May 2017 and over a period of three years, and multiple phases of exploration Rumble has generated 45 copper-zinc-lead-silver priority targets.
