Activities Overview
Rumble completed its maiden drill program at the Zanthus Project Fraser range. Rumbles technical team are continuing to review the outcome of the program and will assess the results of the DHEM, and an ongoing ground EM program, assays and petrology as it comes to hand to help determine with the next phase of exploration.
Rumble also expanded its footprint in the highly sought after Fraser Range Province. The new 100% Rumble owned exploration license expands Rumbles' Fraser Range foot print to 3,590 sq km. The Thunderdome Project was a strategic low cost acquisition which will enable the Company to utilise its cash for high impact exploration. Importantly Rumble Owns a 100% interest in 13 out of the 14 Fraser Range tenements.
Corporate
The company is committed to conducting further exploration activities across its existing pipeline of targets, in the Fraser Range. Rumble with $1.7m is fully funded to advance preparations for the next stage of exploration at its other Fraser Range projects including Big Red and the Thunderdome Project. At the recently acquired Thunderdome current exploration will include analysing the high quality aeromagnetic data, gravity and geochemical data sets. Once this has been completed a comprehensive exploration program will be put together which will include targeted geophysics and follow up drill programs.
The Company will provide an update on upcoming exploration activities within its Fraser Range portfolio in the near future.
Zanthus Project, Fraser Range
The Zanthus Project is located 20km's east of the Nova-Bollinger nickel copper massive sulphide discoveries in the Fraser Range, Western Australia. Rumble is earning up to 75% from Blackham Resources Ltd (ASX:BLK).
As part of Rumbles systematic exploration program Rumble completed a regional gravity survey covering the entire Zanthus Project looking to identify dense intrusive bodies that may represent Fraser Range Gabbro intrusions. The detailed gravity readings were on 500m by 500m spacing with closer spaced infill readings around gravity highs identified. The program identified areas of high density located in the southern portion of the tenement. Significantly the high density locations are surrounding and coincident with the 5 bedrock conductors at the Zanthus eye.
Following the complétion of the gravity survey Rumble completed it's maiden drill program at the Zanthus Project. The drill program consisted of five RC/diamond holes targeting a cluster of five bedrock conductors in and around an eye feature identified through geophysics.
All five drill holes were pre collared with RC and NQ diamond tails were completed to the target zones. A total of five holes were completed for 1081m, four holes intersected graphitic schists which are interpreted as being the target conductors.
Hole ZNDD002 targeting ZC1 and hole ZNDD004 targeting ZC3 intersected wide zones of quartz biotite garnet gneiss
with graphitic zones also containing minor sulphides including chalcopyrite.
ZNDD005 targeted ZC5 and intersected a wide zone of medium grained leucogabbro down to 200m. This then transitioned into quartz biotite garnet gneiss with a graphitic zone from 260m to 282m.
ZNDD001 targeted ZC4 and intersected a zone of medium grained mafic granulite down to the end of hole at 150.9m. This hole did not intersect any conductive material.

Figure 2 &3: Drill Hole locations into a cluster of 5 bedrock conductors

A downhole EM program has been completed with preliminary data highlighting bedrock conductors consistent with the geology observed in the recent RC and diamond drill program.
The RC chips and diamond core have been logged on site and are being transported to Perth for multi element testing and also for petrology to be completed. The assaying and petrology will provide valuable information in characterisation studies of local geology of the area.
A ground EM program covering additional high gravity areas is nearing completion and results and targets from this program will be released once the final data has been received and processed.
Thunderdome Project – 100% Rumble

Work completed to date included:

- petrology on EOH rock chips from NAC036
Key Term of the project sale:
Rumble acquired 100% for $60k cash payment
During the quarter Rumble acquired the highly prospective Thunderdome Project which was a strategic low cost acquisition which will enable the Company to utilise its cash for high impact exploration.
The Thunderdome Project (E28/2366) covers 140sq km's in the main Fraser Range Gravity ridge associated with dense mafic/ultramafic rocks of the Fraser Range.
The project is adjacent to the Rockford project recently acquired by Legend Mining (ASX:LEG) off the Creasy Group as announced on 2 July 2015. It has a large prominent dome feature clearly visible on regional airborne magnetic images. This large dome feature is one of the largest in the Fraser Range and has a fold axis of some 22km. Within this larger target area are also several smaller features which may represent later stage intrusions.
Previous exploration for nickel and copper has recently been carried out by Ponton Minerals which is part of the Creasy Group. This regional exploration was of reconnaissance air core drilling on a 5km by 15km spacing with two holes within the current project area of E28/2366. One of the historic aircore drill holes (PNAC036) was highly anomalous in copper and zinc. Drill hole PNAC036 returned an intersection of 6m @ 0.11% Cu & 0.28% Zn from 51m (EOH 109.5m). This intersection was within a carbonaceous unit which is part of the cover sequence.

Thunderstorm Project – 100% Rumble
Applications E28/2527, E28/2528 and E28/2529 covers 160sq km's in the Fraser Range. There are portions of these tenements that are subject to competing tenement applications and Rumble have lodged 'objections to grant' which is scheduled for Kalgoorlie Wardens Court. These applications abut the Buxton Resources Ltd prospective Zanthus project that are currently RC drill testing 2 high priority conductors on the project. Previous drilling by Buxton identified three separate zones of finely disseminated, magmatic nickel-copper sulphides at their Zanthus project. The presence of magmatic nickel sulphides within mafic to ultramafic intrusive rocks (similar to the host rocks at Nova- Bollinger) indicates that the project is highly fertile and prospective for the discovery of nickel-copper sulphide mineralisation.
Application E28/2523 covers 206 sq km's in the Northern Foreland of the Albany - Fraser Range. This has been interpreted to host similar intrusive features to that being explored by Windward Resources Uraryie and Uraryie South Prospects. Drilling in December 2014 of the Urayie prospect returned anomalous nickel assays up to 0.55% Ni. Initial drilling of the Uraryie South Intrusive complex is planned for Q2 of FY16 following completion of a heritage survey.

Big Red Project – 100% Rumble
No exploration was completed during the quarter. The Big Red Project is located 450 kilometres east of Kalgoorlie in the Fraser Range Western Australia.
A maiden drill program was completed in the December quarter consisting of 4 Mud Rotary/Diamond drill holes totalling 1,503.9m with the programme designed to test a 2km EM conductor outlined by a high powered ground EM survey
Rumble received all assays from its maiden drill program with the assays confirming all three holes intersected large disseminated mineralised sulphide zones within gabbros of the Fraser Range Complex. These sulphide zones are of considerable widths and indicate this large conductor to be a significant mineralised system. Intersecting Fraser Range gabbro is of significance as it is the rock unit which can host magmatic Ni-Cu sulphide deposits.
Detailed petrographic analysis of samples collected from the recent diamond drill program has confirmed the presence of magmatic sulphides. Nickel (pentlandite) and Copper (chalcopyrite) sulphides in association with pyrrhotite and magnetite are present within Fraser Range gabbro.
Following the drilling Rumble completed a Downhole EM Program which identified 2 very high conductance off hole conductors of 6000 to 8000 siemens which can be typical of massive sulphide accumulations. It is noted that the petrology has not indicated any conductive units within the lower portion of hole BRDD003. Hole BRDD002, which is located 400m to the south, contains the mineralogy present in magmatic nickel copper feeder systems with sulphides of pyrrhotite, chalcopyrite pentlandite and also magnetite. This now makes these off hole conductors first order targets in the company's exploration of the Fraser Range.
