Barramine High Grade Cu-Pb-Zn-Ag Project, East Pilbara Western Australia

Exploration target(s) are the same as at the Braeside Project:

  • 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.

Rumble has an option agreement to earn up to 70% of the Barramine High grade Cu-Pb-Zn-Ag Project. The Barramine Project E45/4368 is located approximately 150km ENE of Marble Bar in the Pilbara Region of Western Australia (Image 1) and contiguous to Rumbles Braeside project.

Previous Exploration

The Barramine Project consists of a number of untested high-grade Cu, Pb, Zn, Ag and Au prospects and occurrences associated with a major NNW fault zone within mafic volcanics and volcaniclastic.

Two locations within the Barramine Project have been subject to historical prospecting pits and minor grab sampling for base metals in the Barramine and Camel Hump Prospects.  Both prospects are related to steep NNW trending reverse faults that contain copper, lead, Zinc and silver.  Previous work has shown the historical samples were taken on the structures to be similar in style to the Braeside-style structures to the south east.  

  • At the Barramine prospect a channel sample collected by Blatchford in 1925 assayed 25.32% copper, 279 g/t silver, and a trace of lead. 
  • At the Camel Hump prospect, rock chip samples were assayed up to 13.4% Copper, 6% Lead, 1.8% Zinc and 131 g/t Silver.

Regional Soil Programme and Results 

Contiguous northern extension of Central Braeside tenement E45/2032 (host to 35km by 6km porphyry to epithermal mineralised system)

Regional soil sampling on a staggered 400m by 400m pattern with select 200m by 200m infill was completed over interpreted structures within Fortescue mafic dominant volcanics and volcaniclastics. Areas of shale (Jeerinah Formation) were also partly covered. A total of 286 samples were collected and assayed for gold and 32 multi-elements. The soil programme focused on the northern section of the interpreted mineralised structures due to access restraints.

The maximum soil value is 844 ppm Pb + Zn (392ppm Pb, 452ppm Zn). Nine (9) samples returned > 300ppm Pb + Zn. Several anomalies have been highlighted (see image 2) with the most significant anomaly occurring over a strike of 4km.

The majority of the anomalies lie close to, or over the inferred regional mineralised structure that extends north to northwest from the Barker Well Prospect (neighbouring E45/2032 tenement) into the Barramine project. The soil sampling methodology and analysis was identical to the extensive soil sampling conducted within E45/2032. The level thresholds of anomalism for the Barramine JV are approximately the same as for E45/2032.

Regional geological reconnaissance along the main structure that extends north to northwest from the Barker Well mineralisation reported similar styles of alteration to the Barker Well – Gossan East Trend (in E45/2032) with wide zones of silicification and extensive pervasive chlorite alteration. Results from the regional soil sampling and the reconnaissance has extended the main mineralised structures a further 18km of strike within the Barramine JV. The Braeside porphyry related mineralised structure has been confirmed over a strike of over 60 km.
