Rumble Resources Limited (ASX: RTR) has announced the discovery of wide zones of shallow copper and lead breccia pipes from the drilling activities on the Braeside project located in the Pilbara, Western Australia.
The company reported that wide zones of shallow copper were discovered at the Camel Hump Cu Prospect. RTR said that the maiden RC drilling program discovered significant near-surface copper (visual – oxide copper) in six holes – up to 40m width. The assays are pending. RTR said that the mineralisation style is considered volcanogenic (VMS).
Rumble reported the discovery of Pb breccia pipes at the Barker Well Pb-Zn-Ag Prospect. The company said that the first batch of assays intersected shallow lead mineralisation. Results included 6m @ 7.58% Pb, 7.7 g/t Ag from 25m; 3m @ 14.23% Pb, 1% Zn, 9.3 g/t Ag from 30m; and 3m @ 6.07% Pb, 6.4 g/t Ag from 15m. The company said that three breccia pipes were defined over 750m of strike (completely open). RTR said that assays are pending from 33 drill holes.
Braeside project
The Braeside project is located in the East Pilbara region of Western Australia, comprising 673 km2. The Braeside project comprises Four (4) granted exploration licenses – E45/2032, E45/4368, E45/4873, and E45/4874 and one (1) exploration license application E45/5689.
E45/2032 is Rumble Resources 70% and Maverick Exploration Pty Ltd 30%. E45/4368 is currently owned by Great Sandy Pty Ltd and Rumble has earned 70% of the tenement. E45/4368 is Rumble Resources 70% and Great Sandy Pty Ltd 30%. All other exploration (and applications) licenses are 100% Rumble.
Significant prospects include Camel Hump, Camel Hump South, Barramine Cu, Bayonne Bleeder, Bonecrusher, and No Dice Chicun prospects.
Drilling at Braeside project
The company had recently commenced an RC drilling program at the Braeside Project. Rumble said that EIS (state government) is co-funding to $150,000 for this drill program.
The company said that five targets/prospects were tested with shallow RC drilling and 81 RC drill holes were drilled for aggregate of 3710m. RTR reported that 42 drill holes were drilled at Barker Well and Camel Hump Prospects.
The company has now reported the assay results from 39 holes. Rumble reported that all prospects returned strong base metal mineralisation. RTR noted that at the Camel Hump and Barker Well Prospects very significant copper and lead mineralisation was discovered.
Significant Copper and Lead discovered
RTR said that in the maiden drill program at the Camel Hump Prospect, the company discovered wide zones (up to 40m wide) of near surface copper interpreted to be VMS mineralisation. At the Barker Well Prospect Rumble discovered three Pb breccia pipes with high grade Pb mineralisation. Both prospects are open in all directions with assays pending.
Camel Hump Cu prospect
The company announced that the maiden RC drill program (eight drill holes) at the Camel Hump Prospect was completed with very significant (visual) oxide copper mineralisation discovered in six shallow RC drill holes with assays pending.
RTR said that stringer style malachite, azurite, chalcocite, and native copper observed over widths up to 40m (drill hole length intersection) are associated with intermediate volcaniclastics (siltstone) within andesite. Rumble said that at the base of the siltstone is manganiferous silic altered (sulphidic if fresh) black shale. Structural observations have indicated the copper mineralised volcaniclastic zone pre-dates foliation.
The company said that the style of mineralisation is considered volcanogenic and likely represents stringer copper sulphide zoning associated with VMS (volcanogenic hosted massive sulphide) type systems.
Barker Well prospect
Rumble announced that at the Barker Well Prospect, it has discovered three (3) Pb breccia pipes defined over 750m which are completely open along strike and at depth by shallow RC Drilling.
The company said that the breccias pipes have formed at surface and are composed of massive galena with sphalerite within silica – chlorite – pyrite alteration zones with strong pervasive galena – pyrite – sphalerite haloes. The host rocks are andesitic basalts and volcaniclastics.
First assay results for nineteen (19) RC shallow drill holes included 6m @ 7.58% Pb, 7.7 g/t Ag from 25m (BRRC141); 3m @ 6.07% Pb, 6.4 g/t Ag from 15m (BRRC142); and 3m @ 14.23% Pb, 1% Zn, 9.3 g/t Ag from 30m (BRRC155).
Within the Pb mineralised intersections, high-grade metre intersections included 22.3%, 18.3%, 17.1%, and 15.5% Pb. RTR said that the assays for a further thirty-three (33) RC drill holes are pending.
Other prospects
RTR said that other prospects that returned strong base metal mineralisation included Lightning Ridge, Gossan East, and Zinc Ridge prospects.
Intersections from Lightning Ridge prospect included 3m @ 4.81% Pb, 25.6 g/t Ag from 29m (BRRC129); and 2m @ 4.7% Pb, 15.7 g/t Ag from 28m (BRRC130).
Significant hits from Gossan East prospect included 2m @ 3.08% Pb, 1.56% Zn, 6.2 g/t Ag from 22m (BRRC132); and 3m @ 3.16% Pb, 0.49% Zn, 4.3 g/t Ag from 23m (BRRC134).
RTR said that Zinc Ridge prospect included flat zones of sauconite (Zn smectite) anomalism within fresh intermediate tuffs highlights potential for non-sulphide Zn mineralisation. Important intersections included 8m @ 0.8% Zn from surface (BRRC118); 5m @ 0.8% Zn from surface (BRRC119); 6m @ 1.0% Zn from 5m (BRRC120); and 8m @ 0.85% Zn from surface (BRRC122).
E45/4368 now part of Braeside
Rumble said that the vendor agreed that Rumble has now earned its 70% legal and beneficial title to the asset E45/4368 (excluding the Fe/Mn Rights). This project was previously named the Barramine Project but will now form part of the Braeside Project. E45/4368 hosts the Camel Hump Prospect.
Next steps
The company said that the following geophysics are planned for Braeside subject to all assay results – AEM over Camel Hump; and IP over Barker Well.
