Rumble Resources Ltd ("Rumble" or "the Company") is pleased to provide an update of the Company's activities. Rumble's activities were focussed on expanding and exploring its Fraser Range Projects, which are located in an emerging world class nickel province in Western Australia. Generation of drill targets were successful at Zanthus complementing the compelling Voisey's Bay target at Big Red, offering considerable leverage to Rumble shareholders
Primary Exploration Activities Big Red, Fraser Range
Rumbles maiden drilling programme in the Fraser Range has been scheduled at its Big Red Project. Drilling contracts have been awarded to DDH1 with the drilling rigs to be mobilised for the 7th of November. The drilling programme is expected to take two weeks to complete with assays to follow. DDH1 will utilise a high powered Sandvick multipurpose RC/Diamond truck mounted rig, top of the line for power, accuracy and has 2500m NQ depth capacity.

Rumbles technical team has completed a plan to RC/Diamond drill 4 holes totalling 1600m. The programme is designed to test the EM conductor within the interpreted Voisey Bay feeder Structure – See Figure 1. The compelling target will be drilled first with an RC pre-collar to approximately 150m and a diamond tail through the conductor plate, which has been modelled at 200m. Following the completion of the program a down-hole EM survey will be looked to be scheduled to provide a diagnostic test of further bedrock conductors.
As part of the exploration activities Rumble has been awarded $150,000 to co-fund exploration on the Big Red Project through the WA Government's Exploration Initiative Scheme (EIS).
A 3D inversion model at the Big Red Project highlighted an interpreted feeder zone that is both conductive and magnetic. It is north plunging and is coincident with the 2.2 km conductor. This feeds into a large 6km gravity body located to the northwest which is interpreted as a large magma chamber– See Figure 2. All these elements fit the Voisey bay model – See Figure 3.

Figure 2: Big Red Project, Showing EM Conductor located in an Interpreted Feeder Zone into a Magma Chamber.
The feeder zone target model is the "Ovoid" deposit at Voiseys Bay, a 600m long by 350m and 110m deep body of massive sulphides located in the upper part of a feeder dyke – see figure 3. The "Ovoid" mineralogy includes magnetite, pyrrhotite (both magnetic) and nickel and copper sulphides (conductive). The Voisey's Bay Ni-Cu deposit is one of the most significant discoveries made in the world at 35 mil tonnes at 3.5% Nickel.

Strategic Application Licenses
The Company made two strategic exploration licence applications adjoining the existing Big Red Project and contiguous to the new applications made by Vale in the Fraser Range in Western Australia. Vale is the world's second biggest producer of nickel and recently applied for two license applications south of Rumbles Big Red Project and east of the Thunderstorm Project in the Fraser Range highlighting the quality of rumbles projects. See Figure 4. Vale owns Voisey's Bay which is one of the largest nickel mines in the world. Their entry into the region underlines the potential of the Fraser Range to host additional magmatic nickel copper mineralisation in the region.
The two new applications increase the Big Red Project to 1491 square kilometres and expand Rumble's Fraser Range foot print by 71%. Rumble secured this license for nil consideration and will continue to strategically expand its foot print providing Rumble shareholders multiple opportunities to make the next significant nickel discovery.

Figure 4: Big Red Project, Showing New Applications.
Zanthus Project, Fraser Range
The Zanthus Project is located 18km's east of the Nova-Bollinger nickel copper massive sulphide discoveries in the Fraser Range, Western Australia.

Rumble completed a high-powered moving loop ground based EM survey (MLTEM) targeting bedrock conductors which represent drill targets for magmatic nickel sulphides. The Company identified three priority target areas for its first detailed ground EM program on the Zanthus Project. One of three priority target areas was an "eye" feature interpreted as an elliptical magnetic rimmed intrusive body some 2km in length and up to 1km wide and of similar size to the Nova "eye" feature.
Initial processing of the data covering the eye feature has generated some impressive results with 5 conductors identified. Named ZC1–ZC5. See Figure 5.

"Eye" shaped magnetic features are indicators which are commonly associated with mafic intrusive complexes that host Ni-Cu-PGE ore bodies. Therefore these eye features are priority targets when exploring for massive sulphide ore bodies. The world class Nova massive sulphide nickel copper discovery was found through drilling a bedrock conductor within an "eye" intrusive.
The modelling is only at its preliminary stages with these initial interpretations:
- ZC1, ZC2 and ZC3 are of significant conductance and are situated at reasonably shallow depth to top (~100- 200m) which be a high priority for the next stage of drilling. See Figure 6.
- ZC4 and ZC5 Ongoing infill ground EM with additional processing to work out the conductivity, strike, dip and depth of the bodies.

Figure 6. Preliminary model of the 3 processed conductors ZC1, ZC2 & ZC3.
Ongoing Ground EM Program
The ground EM program was extended due to the success of the early stages of the geophysics program with the potential for further conductor identification over the following weeks.
As more detail emerges of the 5 conductors and any further conductors identified in the ongoing program, they will be prioritised on the basis of these attributes and geology to underpin future drill programs.

EM programs has highlighted the enormous potential of the Zanthus Project. Rumble will be planning further ground EM programs over other large intrusive bodies interpreted from the magnetics data looking to identify further conductors that may represent magmatic Nickel sulphides. The Company also identified a significant structural corridor with numerous large intrusive features and significant magnetic highs. This zone is a significant structural break in the regional geology and covers a large area some 14km by 5km and will be a main focus area of next stage of geophysics exploration which requires a systematic exploration approach. See Figure 7.
