Stage 2 – VTEM survey - E45/2032
rumbleresources.com.au
- The VTEM survey has defined multiple conductors that are importantly associated with the identified regional base metal trends, historic high-grade base metal rock chip sampling and key geological structures that represent first order VMS Targets
Stage 3 – Infill geochemistry over metal trends and conductors - E45/2032
- Infill 200m by 200m soil geochemistry program has commenced over the base metal trends and conductors identified in Stage 1 and 2
Rumble Resources Ltd (ASX: RTR) (“Rumble” or “the Company”) has successfully completed the Stage 1 soil program and Stage 2 helicopter-borne (VTEM) electromagnetic geophysical surveys at the historic Braeside High Grade Zinc – Lead Project (“the Project”), which have produced significant results.
Rumble’s Managing Director, Mr Shane Sikora, said : “Rumble is excited at conducting the first modern systematic exploration program at the Braeside Project, which hosts many historic high grade base metal small-scale mines associated with altered geological structures that produced lead, zinc and silver up until 1959. Historical high grade grab sampling assays previously returned up to 18.9% Zn, 79% Pb, 11.64% Cu, 325 g/t Ag and 13 g/t Au with numerous high grade untested Zn, Pb and Cu prospects throughout the entire 30km of strike at the Project.

The Company is pleased to report that the first 2 stages of exploration have been incredibly successful delivering fantastic results.
The broad spaced regional soil sampling program has identified significant zinc, lead and copper metal trends throughout the entire 30km of strike at the E45/2032 Braeside Project which are importantly coincident with key geological structures and historic high grade base metal rock chip samples. Historically, mineralised trends with high grade rock chips samples located within key geological structures have proven to be key path finders in discovering major base metal deposits.
The VTEM survey has highlighted a multitude of conductors, importantly many are associated with the identified regional base metal trends, historic high grade base metal rock chip sampling and key geological structures. Based on the earlier litho-geochemistry work competed by Rumble which identified the VMS potential of the project, the newly defined conductors represent first order VMS targets.
Rumble will continue to fast track the systematic staged exploration at Braeside with the aim of providing its shareholders with the best chance of making a large base metal discovery. The Company will now focus on refining key VMS drill targets by completing the stage 3 infill soils along the base metal trends and conductors identified. Upon completing stage 3, The Company will assess the conductors, geological structures, regional metals trends and historic high grade base metal rock chips throughout the Braeside Project to rank key targets for Stage 4 Ground EM.
Rumble is fully funded to complete all stages of exploration and expects to complete the stage 5 drill testing of the first order VMS targets prior to the end of 2017.”

Stage 1 - Regional soil geochemistry (multi-element) - E45/2032
Rumble completed the first ever regional soil geochemistry program completed at the Braeside Project which covered the entire E45/2032 license and was primarily designed to delineate base metal and gold geochemical trends.
In total, 1229 samples were collected on a staggered 400m by 400m grid over the entire area of granted EL45/2032. The samples were analysed utilising a 33 element suite (aqua regia digest with MS finish).
The soil sampling program was incredibly successful with significant zinc (>100ppm) and lead (>100ppm) trends up to 4km’s long identified throughout project which importantly are coincident with key geological structures and historic high grade base metal rock chips.
Historically mineralised trends with high grade rock chips samples located within key geological structures have proven to be key path finders in discovering major base metal deposits.

The maximum Zn in soil value is 1493 ppm with twenty four (24) >200ppm anomalies defined.

Stage 2 – Airborne VTEM - E45/2032
Rumble completed the first ever helicopter-borne Versatile Time Domain Electromagnetic (“VTEM”) geophysical survey at the Company’s Braeside Project – E45/2032. VTEM is one of the world’s highest resolution and signal-to-noise ratio airborne electromagnetic systems and is a proven exploration tool in discovering large scale base metal deposits. The survey was completed by Geotech Ltd.
The VTEM survey covered an area of approximately 450 line kilometres at flight line spacings (perpendicular to stratigraphy) of 400 metres.
Historic airborne Tempest AEM has provided confidence that there are no, or very minor, lithological conductors such as graphitic shales along the known base metal mineralised system at the Project.
The VTEM program was extremely successful with preliminary VTEM processing (using Maxwell software) defining a multitude of early and late time conductors. Significantly the conductors strongly correlate the known structural directions, coincide with the extensive zinc, lead and copper geochemical trends and historic high grade base metal rock chip sampling.
Based on the earlier litho-geochemistry work competed by Rumble which identified the VMS potential of the project, the newly defined conductors represent first order VMS Targets.

Stage 3 – Infill Geochemistry
The field crew has been redeployed to complete an infill soil geochemistry sampling program across the metal trends identified in Stage 1 and over conductors identified by the VTEM in Stage 2. The infill geochemistry will help rank key targets for Stage 4 Ground EM.
Once completed stage 3 the company will assess the conductors, geological structures, regional metals trends and historic high grade rock chips throughout the project to rank key targets for Stage 4 Ground EM.
Systematic Exploration Process of High Grade Zinc Lead Braeside Project
The Braeside Project consists of multiple high grade zinc, lead, copper and silver deposits and occurrences associated within a major NNW fault zone within mafic volcanics and volcaniclastics over a strike of at least 80 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 and1951.
Rumbles exploration program is the first modern systematic exploration program being undertaken at the Braeside High Grade Zinc – Lead Project.
Significant High grade historical grab sampling returned up to 18.9% Zn, 79% Pb, 11.64% Cu, 325 g/t Ag and 13 g/t Au with numerous untested Zn, Pb and Cu prospects throughout the entire 30km of strike.
Please see ASX presentation announced on the 11 May 2017 which highlights the high grade rock chips throughout the entire 30km of strike: http://www.asx.com.au/asxpdf/20170511/pdf/43j61hglpxfm80.pdf .
Note: Subsequent this presentation Rumble raised $1.06mil in a placement announced 27th June 2017 and is now fully funded to complete all 5 stages of exploration.
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.
Rumble is fast tracking exploration as per the stages outlined below. The first 4 stages are anticipated to be completed over the coming months, and the Company expects to complete the stage 5 drill testing of any first order VMS targets identified prior to the end of 2017.
