Braeside-Barramine Zn-Pb-Cu-AG-Au-V Project , East Pilbara Western Australia

Exploration target(s)

  • Porphyry related structurally controlled high-grade Zn-Pb-Cu-Ag-V breccia pipes
  • High level (epithermal) base metal veins
  • Sediment hosted disseminated base metal replacement zones
  • Porphyry related stock-works

The Braeside-Barramine Project, located in the east Pilbara region of Western Australia, comprises an area of 1813 km² covering over 60km of prospective strike for significant mineralization.  Polymetallic high-level vein sets discovered by Rumble are considered to be part of a large porphyry to epithermal alteration and mineralization system related to potential underlying Fortescue (2.7 Ga) felsic (subvolcanic to aerial volcanics) and associated A type granitoids.

Prior to Rumbles acquisition there had been no modern systematic exploration on the high-grade Braeside project.

  • Exploration by Rumble has now outlined a large mineralised vein array system over 60km in strike and 8km in width.
  • 14 High Priority Targets have been identified.

14 High Priority Drill Targets (see image 1)

  1. Moxam’s V-Pb – Very high-grade V and Pb defined over a strike of 400m (Mineralisation is open). Very high-grade grab samples include:

BR507 – 6.75% V2O5, 48.25% Pb.   BR640 – 4.62% V2O5, 16.71% Pb.   BR643 – 6.62% V2O5, 31.3% Pb.                                    

BR647 – 3.44% V2O5, 16.64% Pb.   BR646 – 2.82% V2O5, 29.68% Pb.   BR634 – 3.87% V2O5, 16.34% Pb

  1. Far North Gossan Zn-Pb  - Strong alteration over 500m. Limited grab sampling has returned Zn of 8.32%, 4.23% and 6.45%. Pb returned 9.34% and 3.4%.
  1. No Dice Chicun Zn-Pb - Soil anomaly 1km by 200m with Zn to 560ppm and Pb to 422ppm. Limited grab sampling includes Zn to 1.4%, Pb to 34% and Ag to 88 g/t.
  1. Barramine Zn South - Large 2km by 1km soil anomaly Zn to 1200ppm and Pb to 700ppm.
  1. Barramine Zn North - 800m by 400m soil anomaly with Zn to 317 ppm (background 50ppm.)
  1. Camel Hump Cu - Shear zone over 1.5km in strike. Limited grab sampling includes Cu to 13.4%, Pb to 6.04%, Zn to 1.79%, Ag to 131 g/t.
  1. Bonecrusher Au-Zn - Large Au in soil anomaly, 1km by 500m has returned up to 25ppb Au (>5ppb Au threshold). Limited grab sampling has returned Zn to 2.53% and Pb to 1.24%.
  1. Great Southern Zn - Soil anomalism over 1.4km (open) returned Zn to 498ppm (40ppm background) and Pb to 293ppm (15ppm background).
  1. Slimrose Ba Pb Target - A large alteration zone 600m by 500m is associated with strong Ba (to >2000ppm) and Pb (571ppm) soil anomalism. A single grab sample returned 0.52% Pb.
  1. Barker Well Pb - Wide zone (50m) of strong alteration and sulphides with intercepts:  3m @ 9.16% Pb, 0.43% Zn, 6m @ 6.16% Pb within broad zones of alteration (105m @ 0.78% Pb + Zn) -   5 holes have tested 500m of strike – completely open.
  1. Gossan East Pb Zn Cu - Zone of strong mineralisation open to the north (towards Barkers Well). Intercepts: 8m @ 1.23% Zn, 1.27% Pb, 0.14% Cu and 4m @ 3.48% Zn, 0.4% Cu.
  1. Lightning Ridge Pb Ag In - Epithermal vein (250m strike faulted). Other veins identified – ongoing exploration.  Drill intercepts include 4m @ 6.35% Pb, 14.7 g/t Ag and 4m 5.42% Pb, 0.45% Zn, 19.7 g/t Ag.
  1. Barium Ridge Ba Pb Au - large scale Ba-Kspar-Silic alteration. Potential for porphyry related disseminated mineralisation. Some 14km of barium-potassic-silica alteration has been identified. Intercepts include: 58m @ 2.32% BaO (with elevated Pb), 86m @ 1.96% BaO (includes 57m @ 0.22% Pb) and 26m @ 3.84% BaO, 0.18% Pb (includes Au to 0.96 g/t over a metre).
  1. Sugar Ramos Pb Cu Au – Intense widespread alteration including sericite and Kspar with magnetite, barium, rubidium and actinolite. Elevated Cu (to 917 ppm) and Au. Proximal to potential porphyry mineralisation.


Exploration Model - Preserved Near Complete Porphyry to Epithermal System 

Rumble completed only the second regional RC drill program at Rumble’s flagship Braeside Project, which discovered significant high-grade lead and wide zones of barium. Furthermore, the exploration results have defined four systems of mineralization that are associated with a large porphyry related polymetallic vein system with mineralization over a strike length of 35km and up to 6km in width.

The new interpretation of the porphyry related geological model has identified a preserved, near complete porphyry to epithermal system, which is a rare discovery for Archaean age rocks. The exploration model is based on the results and interpretation of geology, alteration and mineralization from the RC drilling completed.

The exciting new development has significantly upgraded the Braeside Project to a regional scale base metal system located in the East Pilbara/Paterson region known for large scale deposits.

Rumble will now be targetting large Cu-Au disseminated porphyry deposits along with high grade base metal vein/breccia pipe and epithermal Pb-Zn-Ag-In+/- Au deposits. Rumble understands that to have three deposit type targets at one project is a unique occurrence, providing Rumble shareholders with significant exposure to exploration results and discovery.

Next Steps

14 high priority targets made up of (9) nine new targets (no drilling) recently defined and (5) five prospects outlined during the 2018 RC drilling programme (see Image 1) have significant base metal and alteration intercepts and are open along strike.

  • Infill surface geochemistry with prospect mapping will define drill targets for the new (9) nine targets.
  • Up to 14 targets will be tested by RC drilling along strike and at depth.
