12 October 2017 Rumble Enters Option Agreement to Acquire Earaheedy Zinc Project
Highlights
- Wide spaced drilling has defined stratiform zinc and lead mineralisation over 20km of strike within carbonate sediments of the lower sedimentary units of the Earaheedy Basin (Proterozoic) in Western Australia.
- Historical drilling intercepted high-grade zinc up to 18.6% within an intersection 3.3m @ 11.2% Zn, and 0.93% Pb from 150m. Other drill-holes include 2m @ 8.23% Zn and 2.77% Pb from 103m.
- Coarse grain sphalerite (Zn) and galena (Pb) with pyrite and marcasite occurs as breccias, veins and replacement zones within carbonates.
- The mineralisation style is similar to Mississippi Valley Type (MVT) large high grade base metal deposits that include the Devonian Lennard Shelf deposits of the Kimberley Region of Western Australia.
- Rumble plans to commission a detailed gravity survey to compliment the magnetics with the aim to delineate basement structures and directly define high density sulphides to drill test.
Rumble Resources Ltd (ASX: RTR) ("Rumble" or "the Company") is pleased to announce that it has signed a binding option agreement to acquire up to 75% of the Earaheedy Zinc Project (E69/3464 – 75 km²), located approximately 110km north of Wiluna, Western Australia, covering most of the known zones of primary carbonate-hosted zinc – lead mineralisation in the Earaheedy Basin.
Whilst Rumble is focussed on fast tracking the first modern systematic exploration at the Braeside Project located in the Pilbara region of Western Australia, targeting high grade Zn–Pb–Ag-Cu-Au deposits leading up to a drill program expected prior to the end of 2017, Rumble has been continuing to implement a clear strategy to proactively identify and review mineral exploration opportunities that complement the Braeside Project, and must pass a critical review by Rumble's technical director Brett Keillor.

Exploration Overview
Broad spaced drilling (completed in the 1990's) defined several prospects containing oxidised and primary Zn-Pb mineralisation (zinc dominant) associated a flat lying to shallow northeast dipping laterally continuous dolomite horizon with over 20 kilometres strike. The initial drill spacing was 5 to 10km. The current drill spacing is approximately 1km by 1km. Three prospects were defined within the current Earaheedy Project (E69/3464).
At 'Navajoh', an intersection of 7.3 metres @ 6.1 % Zn, 0.77% Pb (including 3.3 metres @ 11.2% Zn, and 0.93% Pb) remains untested for 500 metres to 1 kilometre in all directions.
At 'Magazine' there are no follow up holes within a 1kilometre radius of a discovery intersection of 11 metres @ 3.5% (Zn + Pb) which includes 2 metres @ 8.2% Zn, 2.8% Pb).

Table 1. Selected drill intersections from the Navajoh, Magazine and Chinook Prospects
Zinc and lead mineralisation with elevated silver is associated with the Navajoh Dolomite Member (also known as the Sweetwaters Well Member) of the Yelma Formation. The Yelma Formation is the lower unit of the 5000m thick Earaheedy Basin (Palaeoproterozoic). Sphalerite, galena, pyrite and marcasite (coarse grain) occurs as stratiform/stratabound ore fill veins and breccias, dissolution cavity fill, disseminated, stylolitic and fault fill mineralisation styles.
The mineralisation style is considered Mississippi Valley Type (MVT) with metal rich brines (dewatering during diagenesis) migrating laterally and following up late basin structures to react with carbonate rocks precipitating Zn and Pb sulphides. Subsequent later faulting has likely remobilised sulphides and potentially developed high angle higher grade base metal mineralisation.
Narrow high-grade silver mineralisation (TDH16 – 2m @ 149 g/t Ag (4.8 oz/t) from 223m and 4m @ 559 g/t Ag (18 oz/t) from 257m) may represent remobilisation of sulphides.

Exploration Potential
A review of the historic drilling has concluded that approximately half of the drill holes did not intercept the target horizon. A total of 64 drill holes were completed within the project area (E69/3464) with only 35 drill holes intercepting the stratiform zinc horizon (including partial end of hole intercepts).
Structural contouring of the flat lying mineralised carbonate horizon by Rumble has highlighted the extent of mineralisation. Using Zn%-m (cumulative assay values > 0.15% Zn per hole) contouring as a guide (see Image 2), significant areas of untested potential mineralisation remain completely open. North of the Magazine prospect (image 2), drill hole spacing is up to 2km. Note that the Zn%-m contouring represents metal endowment per drill hole and does indicate economic grade and widths.

Image 2. Structural Contours (Zn%-m) Drill Holes Intercepting Mineralised Horizon.
Review by Rumble has highlighted strong zinc and lead zonation associated with the Magazine and Navajoh Prospects. Based on Zn:Pb ratios of the total zinc and lead metal endowment of the drill holes that intercept the mineralised zone, the zonation is parallel to the host geology and an inferred low to moderate angle fault structure delineated by aero-magnetics beneath the Yelma Formation. Image 3 presents the strong Zn:Pb zonation and the potential late basin low to moderate angle bedding fault.
The significance of the zonation and the inferred bedding parallel fault is:
- The zonation has not been modified by later transfer faults and reflects the main mineralisation phase.
- The parallel bedding fault is potentially mineralised and may have been the main conduit for the zinc and lead mineralisation.
- The intersections of the cross cutting faults (including transfer faults), the parallel bedding fault and the stratiform mineralised carbonate horizon are high order targets for high-grade Zn and Pb deposits.

Exploration Model and Strategy
Rumble considers the exploration model to be analogous to known MVT (Mississippi Valley Type) deposits worldwide whereby high grade Zn – Pb sulphide mineralisation is associated with moderate to high angle faults.
The Earaheedy Project, based on the mineralisation style, host rocks, known basement structural architecture and the current drilling density (2km by 1km and 1km by 1km spacing), has the potential to host a significant Zn – Pb resource.
The target size is similar to the Pillara (Blendevale) Zn – Pb deposit located in the Devonian limestones of the Lennard Shelf, Kimberley Region, Western Australia which produced 10.3 Mt @ 6.9% Zn and 2.3% Pb. Of note, the discovery drill-hole (8m @ 8.9% Zn, 3.5% Pb below 210m) at Pillara, was the 136th drill hole in that project

The exploration strategy planned by Rumble includes:
- High resolution gravity survey
- o With carbonates underlaying the entire Earaheedy Project area, density contrast modelling may help delineate basement structures that reflect mineralisation pathways.
- o High density anomalies may be directly related to sulphides.
- Subject to basement structures delineated by gravity and remodelling magnetics, IP or appropriate electrical geophysical method will focus on these structures to define drilling targets and then drill test.
