Drilling has commenced targeting high grade Zinc, Lead and Copper at the Braeside Project, Pilbara WA
Stage 5 Exploration - Drilling at E45/2032
- Drilling has commenced targeting high-grade base metal mineralisation and EM conductors which may represent first order porphyry related (including VMS) polymetallic mineralisation.
- The high grade base metal target areas have grades up to 29.31% Zn, 79% Pb, 17.48% Cu, 325 g/t Ag, 13 g/t Au and V 1.03% throughout the 30km strike.
- Drilling will consist of a 2000m RC drill program targeting approximately 10-15 untested areas.
Rumble Resources Ltd (ASX: RTR) ("Rumble" or "the Company") is pleased to announce that the first modern drilling program at the Braeside Project (E45/2032), located in the Pilbara region of Western Australia, has commenced.
The drilling programme will consist of approximately 2,000m of RC drilling. Rumble has the capacity to extend the drill program, depending on results.

RC Drill Targeting
Targeting has utilised preliminary MLTEM (Moving Loop Transient Electromagnetic survey) conductors (follow up of VTEM conductors), recent grab sampling, base metal in soil geochemical trends and reconnaissance prospecting to optimise priority targets for the current phase of RC drilling.
Rumble is drilling a small portion of the targets identified within E45/2032. Rumble has put in place plans to access these other identified targets after this current program, to generate further high order drill targets in early 2018.
The current programme will be the first modern RC drilling conducted at Braeside since 1951 and accordingly, drilling conditions and depth to potential mineralisation is unknown.
Over ten target areas are planned to be tested along 30km of strike. Targets included are known historic prospects that have returned very high-grade Zn, Pb and Cu grab sampling results and recent exploration results that have highlighted wide alteration zones associated with the high-grade base metal surface mineralisation.
The MLTEM programme (stage 4) has been completed and preliminary results have highlighted eight (8) low order early time conductors that correlate with known north trending mineralised structures. Some of the conductors will be tested by the current RC drill programme.

High-grade base metal grab sampling results associated with the main mineralised structure that extends northnorthwest of the historic Ragged Hills Pb mine RC drill targets will be priority targets for the Ragged Hills Mine area (Image 3). Grab sampling by Rumble along the main steep east dipping mineralised structure (silica – sericite alteration) returned significant results (refer RTR ASX announcement - 16 October 2017) including:
- Pb – 42.8%, 31.5% and 30.7%
- Zn – 17.3%, 7.1%
- Cu – 15.1%
At the Cassius Clay Prospect (Ragged Hills East Area – Image 4), strongly mineralised and altered structures converge and up to 5 northwest trending zones have been identified. The mineralisation at surface is steep northeast dipping and a low order MLTEM conductor has been inferred within the footwall to the main structure. Grab sampling by Rumble (refer RTR ASX announcement - 16 October 2017) has returned high-grade mineralisation at surface with results including:
- Pb – 44.6%, 44.3%, 37%, 31.5%, 28.6% and 19.9%
- Cu – 17.5%
- Ag – 90 g/t, 77 g/t, 63 g/t and 48 g/t
A major altered and mineralised northwest trending and steep north east dipping structure with high grade surface base metal mineralisation associated with small scale artisanal workings at the Devon Cut Prospect (see Image6) is the main RC drill target. Grab sampling by Rumble (refer RTR ASX announcement - 16 October 2017) returned high-grade Pb and Zn mineralisation with strongly elevated Ag, Au and V. Results include:
- Pb – 32.7%, 29.5% and 23.2%
- Zn – 14.4% and 6.3%
- Ag – 85 g/t, 59 g/t and 38 g/t
- Au – 0.37 g/t and 0.17 g/t
- V – 1% and 0.85%
At the Hitman Hearns Target (see Image 7), the recent MLTEM survey has defined a 1.8km long low order early time conductor closely associated with a major north trending structure. The structure is in contact to flat west dipping carbonates, shales and cherts to the west and andesitic basalts to the east. Previous grab sampling completed by earlier explorers have returned copper mineralisation in flat lying cherts immediately west of the major structure. Reported rock chip sampling returned up to 5.3% Cu (refer RTR ASX announcement - 11 May 2017)
Multiple (four) low order early time MLTEM conductors are closely related to major north trending structures at the Barker Well Prospect (see Image 8). At the Barker Well Prospect, a wide zone of silica – sericite alteration returned strong base metal mineralisation and will be RC drill tested. Nearby a small historic working returned up to 38.1% Pb with elevated Zn (0.8%) and Cu (0.4%) (refer RTR ASX announcement - 16 October 2017).
Other targets (refer RTR ASX announcement - 16 October 2017) that will be tested by the current RC drill programme include:
- Sugar Ramos (see Image 2 for location) – very high grade Pb - 42.7% and 27.6%, Ag 72 g/t and strongly anomalous Au – 1.45 g/t associated with strong barium and potassium alteration represents a new occurrence.
- Mt Brockman (see Image 2) – high grade Pb – 12.3% with strong barium and potassium alteration located at historic workings.

Background to Systematic Exploration Process of High Grade Zn – Pb – Cu – Ag - Au – V at the Braeside Project (E45-2032)
The Braeside Project E45-2032 consists of multiple high-grade zinc, lead, copper and silver deposits and occurrences associated with north to northwest trending fault fracture zones within mafic volcanics and volcaniclastics over a strike of at least 60 km. The poly-metallic mineralisation has not been tested by detailed geophysics, geochemistry and very limited drilling with only 10 known historic drill holes in 1928 and 1951.
High grade grab sampling assays have returned up to 29.31% Zn, 79% Pb, 17.48% Cu, 325 g/t Ag, 13 g/t Au and V 1.03% along 30km of strike within a potential 60km strike system.
Rumble's exploration program is the first modern systematic exploration program being undertaken at the Braeside High Grade Zinc – Lead Project.
Recent litho-geochemistry completed by Rumble suggests the mineralisation is associated with sub volcanic rhyolitic porphyry (Koongaling Felsic Volcanics) indicating potential for a VMS system capable of hosting a large base metal deposit.
Rumble's technical team lead by Technical Director Mr Brett Keillor is systematically exploring the Braeside Project generating first order VMS feeder pipe targets using proven, modern exploration techniques.
