Option to Acquire the High-Grade Western Queen Gold Project
Highlights
Rumble Resources Ltd
-
The Western Queen Gold Project is a high-grade gold system with two mined open pit deposits with a combined historic production of 840,000t @ 7.8 g/t Au for 210,000oz
-
Indicated and Inferred Mineral Resource beneath both mined deposits include * 962,000t @ 3.9 g/t Au for 120,000oz
- *Completed by Monax Mining Ltd (ASX: MOX) (Payne Geological Services Pty Ltd) 15 January 2018
-
Historic deep drilling below the Western Queen Central Mine underground workings (underground historic grade of 10.32 g/t Au from 8354 tonnes of ore) has highlighted potential for high-grade gold mineralisation to extend down plunge . Intersections include:
- **6.3m @ 36.09 g/t Au from 305.7m** - **11.8m @ 16.08 g/t Au from 340.4m**
The high-grade mineralisation is open down plunge
-
Significant exploration upside exists – high order gold in lag anomalism and strong laterite gold mineralisation (Cranes Prospect) requires systematic drilling.
-
The project is located within 100km radius of three operating gold mills
The Western Queen Gold Project represents an opportunity to explore for:
-
Additional potential underground high-grade gold resources (Western Queen Central); and
-
Near surface gold resources (Cranes Prospect).

Rumble Resources Ltd (ASX: RTR) (“Rumble” or “the Company”) is pleased to announce that in line with its clear strategy of generating and optioning a pipeline of projects capable of low cost exploration to drill test for high grade discoveries, it has signed a binding option agreement to acquire 100% of the Western Queen Gold Project from Ramelius Resources Ltd (ASX: RMS).
Western Queen Gold Project Overview and Resources
The Western Queen Gold project lies 110km NW of Mt Magnet within the Yalgoo Mineral field of Western Australia (“the Project”). The Project comprises of two contiguous mining leases (M59/45 and M59/208) for a total area of 9.8 km². The holder is Mt Magnet Gold Pty Ltd, an entity owned by Ramelius Resources. The Western Queen Gold Project is located within a 100km radius of three operating gold processing mills ( see image 1 ). The closest mill is the Dalgaranga Mill (48km) which has a capacity of 2.5 Mtpa. The Checkers Mill (Mt Magnet) has a capacity of 1.9 Mtpa and the Tuckabianna Mill has a capacity of 1.2 Mtpa.
Two mined deposits at the Western Queen Gold Project have a combined historic production of 840,000t @ 7.8 g/t Au for 210,000oz . The Western Queen (Central) Mine produced 660,000t @ 8.9 g/t Au for 189,500oz and the Western Queen South Mine (from two stages) produced 180,000t @ 3.6 g/t Au for 20,500oz .
Open cut mining commenced in 1998 at the Western Queen Central deposit and finished in 2001. A decline followed with underground production of 8,355t @ 10.32 g/t Au . A further 74,552t of ore was produced at an unknown grade. The ore was processed at the nearby Dalgaranga mill (closed in 2002). In late 2007, mining commenced at the Western Queen South deposit with the ore trucked to the Checkers Mill in Mt Magnet. The second stage was mined in 2013 and 2014 and also treated at the Checkers Mill.
An indicated and inferred mineral resource was previously completed for Monax Mining Ltd (ASX: MOX) ( Monax ) in January 2018 (Payne Geological Services Pty Ltd – Independent). Rumble has reviewed and verified the indicated and inferred resource, and estimates resource extensions below both mined deposits at 962,000t @ 3.9 g/t Au for 120,000oz . Of note: The high grade zone below the Western Queen Central Pit is based on an inferred mineral resources of 130,000t at 9.0g/t Au for 38,000 ounces .

Geology and Mineralisation
==> picture [83 x 72] intentionally omitted <==
The Western Queen Gold project lies within the Warda Warra (Archaean) Greenstone Belt, a part of the Murchison Province of the Yilgarn Craton. The belt is 35km long and is approximately 2km wide where the Western Queen deposits lie. The belt is north trending and predominantly west dipping and has been metamorphosed to amphibolite grade.
At the Western Queen, the geology is steep west dipping and comprises of intercalated sheared amphibolites of mafic to ultramafic composition with thin iron formation horizons, komatiitic basalt, dolerite sills, and talc chlorite schists. Later dolerite and pegmatitic felsic intrusives cut across the amphibolites and gold mineralisation.
Mineralisation is associated with sheared silic sulphide zones with an ultramafic footwall and a mafic hanging wall. The ore zone is strongly recrystallised and massive, comprising phlogopite-chlorite-tremolite-talc schist, amphibolite with lenticular quartzo-feldspathic layering and quartz-muscovite-biotite-sillimanite schist. Pyrite, pyrrhotite, chalcopyrite, molybdenite and scheelite are present. The mineralisation has a steep westerly dip and a southerly plunge.

Western Queen Central – Down Plunge Potential
==> picture [83 x 72] intentionally omitted <==
Review of the down plunge position of the Western Queen Central deposit has shown high-grade gold mineralisation is open. High-grade historic gold intercepts include:
- 11.8m @ 16.08 g/t Au from 340.4m (WQD-1089)
6.3m @ 36.09 g/t Au from 305.7m (WQD-1072)
==> picture [545 x 401] intentionally omitted <==
Image 4 – Western Queen Central Mine and Deposit – Longitudinal Section with Drill-Hole Pierce Points and High-Grade Plunging Shoot Open
During the underground mining period (2001 – 2002), some 82,907t of ore was mined in two stages and sent to the Dalgaranga Mill which is located 48km to the SSE of the Western Queen Project. The first stage completed was for 8,355t @ 10.32 g/t Au. The second stage (74,552t) was processed as the Dalgaranga Mill (Equigold) was shutting down and the reconciliation of grade is uncertain.
-
An inferred resource of 130,000t @ 9 g/t Au is interpreted below the underground development and is completely open down plunge at a vertical depth of 250 – 350m.
-
Rumble considers down plunge position from the very high-grade intercepts (6.3m @ 36.09 g/t Au and 11.8m @ 16.08 g/t Au ) as a high order target (see image 4) that may potentially have significant mineralisation similar to the historic underground mining grade (10.32 g/t Au).

Cranes Prospect (image 5) – Potential for High-Grade Gold Mineralisation
==> picture [83 x 72] intentionally omitted <==
The Cranes Prospect lies 2.5km NNE of the Western Queen Central Mine (image 3). Historic lag sampling on 100m by 100m spacing with 50m by 50m infill identified a very high-grade gold anomaly 400m in length striking NE. Gold in lag values include up to 8500ppb Au with six (6) sample sites reporting >1000ppb Au. Subsequent historic drilling (RAB, AC and shallow RC drilling) did not find the source of the gold in lag anomalism, however, significant surface laterite mineralisation was defined. Results include 8m @ 1.87 g/t Au from surface and 8m @ 1.29 g/t Au from surface. Review of the historic drilling data has shown the main gold in lag anomalism (see image 5) has not been closed off and along strike (NE trending) no drilling has been conducted.
==> picture [552 x 261] intentionally omitted <==
Image 5 – Western Queen Project – Cranes Prospect – Gold in Lag Geochemistry and Historic Drilling
- Rumble considers the gold in lag anomalism at Cranes is prospective for high-grade gold shoot-like mineralisation (similar style to the Western Queen Central and South Deposits). Significant surface laterite gold mineralisation supports the high order gold in lag anomalism.
Option Opportunity - Potential for additional High-Grade gold resources - Next Steps
Western Queen Central Mine and Deposit
-
The Western Queen Project has potential for additional high-grade gold resources down plunge from historic very high-grade gold intercepts at the Western Queen Central Mine and Deposit – currently open and untested
-
Rumble will complete a geophysical (TEM) survey south of the pit. The survey will aid in drill targeting.
-
Deep RC Drilling targeting plunge extension and geophysical response.
Cranes Prospect
-
At the Cranes Prospect, high order gold in lag anomalism with significant surficial laterite gold mineralisation has not been completely tested - opportunity to find basement mineralisation.
-
Aircore drilling planned, targeting high-grade gold shoot-like mineralisation.

Resource Summary- Western Queen Gold Deposit
Geology
At the Western Queen, the geology is steep west dipping and comprises of intercalated sheared amphibolites of mafic to ultramafic composition with thin iron formation horizons, komatiitic basalt, dolerite sills, and talc chlorite schists. Later dolerite and pegmatitic felsic intrusives cut across the amphibolites and gold mineralisation.
Mineralisation is associated with sheared silic sulphide zones with an ultramafic footwall and a mafic hanging wall. The ore zone is strongly recrystallised and massive, comprising phlogopite-chlorite-tremolite-talc schist, amphibolite with lenticular quartzo-feldspathic layering and quartz-muscovite-biotite-sillimanite schist. Pyrite, pyrrhotite, chalcopyrite, molybdenite and scheelite are present. The mineralisation has a steep westerly dip and a southerly plunge. Depth of complete oxidation is approximately 30m to 60m with depth to fresh rock approximately 45 to 80m. A zone of lacustrine sediments up to 45m thick overlies the WQS deposit.
Drilling
Drilling at the Western Queen project has occurred over multiple campaigns from 1992 to 2017. Previous operators included WMC, Equigold NL, Harmony Gold and Ramelius Resources.
A total of 32 reverse circulation (RC) holes and 16 diamond (DD) holes define the remaining Mineral Resource. All holes in the resource were drilled by previous operators. A very large number of RC and DD holes are present within the previously mined portions of the deposits but these holes were outside the limits of the current Mineral Resources.
6
==> picture [83 x 72] intentionally omitted <==
The majority of the remaining resources have been drilled at 40-60m hole spacings on 50m spaced E-W cross sections. The upper portion of the WQS deposit has been drilled at 25m hole spacings.
All resource hole collars were accurately surveyed using DGPS or traditional electronic equipment. Some historic drill hole collars were surveyed in AMG coordinates and have since been transformed to MGA grid. All holes were transformed to a local grid for interpretation and estimation. Down hole surveys were recorded for the majority of holes at regular intervals using a single shot Eastman camera or a Reflex multi-shot tool.
Sampling and Sub-Sampling Techniques
For the historic RC drilling, a face-sampling hammer was used with samples collected at 1m intervals from mineralised zones with composite sampling of typically 4m in the unmineralised rocks. Samples were collected through a rig-mounted cone splitter or free standing riffle splitter. Samples were reported to have been kept dry throughout the mineralised zones and drilling conditions were stated to have been excellent.
More recent core was NQ2 size and historic diamond core was typically NQ size. All core was sampled to geological intervals and cut with a diamond saw to produced half-core samples for analysis. Core recovery from diamond drilling was recorded in drill logs and was consistently excellent.
Sample Analysis Method
For some of the drilling, half core samples were delivered to the laboratory for total preparation by crushing and pulverisation, before being sub-sampled for analysis using a 40g Fire Assay method. QAQC protocols were in place for the more recent drilling and has confirmed the quality of the sampling and assaying.
The majority of historic RC and diamond drilling was assayed at contract laboratories using a fire assay method. QAQC data from the drilling has been reported in historic reports and although not comprehensive, it supported the quality of the sampling and assaying of the historic data.
Estimation Methodology
The WQS deposit was estimated using ordinary kriging ("OK") grade interpolation of 1m composited data within wireframes prepared using 1.0g/t Au envelopes. The WQC deposit was estimated using inverse distance interpolation. Interpolation parameters were based on the geometry of each zone and geostatistical parameters determined by variography. High grade cuts of between 20g/t and 30g/t were applied to individual lodes.
The block dimensions used in the model were 4m EW by 20m NS by 10m vertical with sub-cells of 0.5m by 5m by 2.5m.
Bulk density determinations from drill core were used to assign density to the model. Values used in the resource estimate were 1.8t/m[3] for Oxide, 2.25t/m[3] for Transition and 2.85t/m[3] for Primary mineralisation were applied.
The remaining mineralisation at both deposits is almost entirely primary mineralisation.
Mineral Resource Classification
Mineral Resource classification was considered on the basis of drill hole spacing and continuity of mineralisation. The portion of was mineralisation immediately beneath the pit floor has been comprehensively drilled at a drill hole spacings of 25m or less. The continuity of mineralisation defined by this drilling is robust and this area has been classified as Indicated Mineral Resource.
In the remainder of the deposits, the drill hole spacings are typically 50-80m. Although lode continuity is assumed to be good, the sample spacing is too great to provide confidence in the grade estimates so these zones have been classified as Inferred Mineral Resource.
Inferred Mineral Resource was extrapolated to a distance of up to 60m past drill hole intersections.
7
Cut-off Grades
==> picture [83 x 72] intentionally omitted <==
The tabular, plunge-extensive and relatively high-grade nature of the deposits suggests good potential for underground mining. The Mineral Resource has been reported at a 2.0g/t Au cut-off based on assumptions about economic cut-off grades for underground mining.
Metallurgy
Historical metallurgical test work has been conducted on the mineralisation at Western Queen. Further work is planned, but it is assumed that metallurgical characteristics are similar to mined portions of the deposits. Historic production has demonstrated that good gold recovery can be expected from conventional processing methods.
Modifying Factors
No modifying factors were applied to the reported Mineral Resource estimate. Parameters reflecting mining dilution, ore loss and metallurgical recoveries will be considered during the planned mining evaluation of the project.
