WATTLE DAM GOLD PROJECT (WA)
Production
Gold production (milled) for the quarter was 39,057 tonnes at a recovered grade of 12.4 g/t Au for 15,601 oz produced. Wattle Dam ore contributed 27,967 tonnes at 14.7 g/t for 13,186 oz and non‐ Wattle Dam sources produced 11,090 tonnes at 6.8 g/t for 2,415 oz.

^ Reconciled cash cost which includes all mining, milling and royalty costs (March, June and Sept Qtrs 2011 do not include capital development of $4.6m, $4.2m and $4.0m respectively whereas previous quarters did include capital development).
A total of 36,270 tonnes was mined at Wattle Dam for the quarter from a combination of development and stoping ore. This comprised of high‐grade ore totalling 29,591 tonnes at an estimated grade of 10.9 g/t and stockpiled low‐grade ore of 6,679 tonnes at 1.7 g/t.
Stope production for the quarter was sourced from the Block B hangingwall stopes (185‐ 200RLs). B Block stoping was completed during September and this finalised mining of the A & B Block mining area.
Decline development reached the lowest planned level (980mRL) during the quarter and was effectively completed.
Development focussed on the D Block footwall ore drives. The 060 and 040 drives were completed during the quarter and development was in progress for the 020, 1000 and 980 FW ore drives. Increased ground support measures have been found to be required in Block D development levels and this will delay milling of Block D stoping ore until January.
Milling of the initial D block ore drive parcels from the 060 and 040 FW drives was completed during the quarter. In general, visible gold occurrences in these levels were less frequent than in the upper mine. Mill grades returned were relatively low, averaging 4.5 g/t. While these results point to D Block grade being lower than in the upper mine, some significant variances in development grades were also seen in the upper mine with development ore parcels varying between 43.5 g/t and 4.7g/t. It should be noted that for mining purposes, these development drives were mined partially in waste and further milling of D block development and stope ore is required to better determine overall grade.
As a result of of these factors production will be reduced in the December quarter 2011.

Underground Drilling
Drilling recommenced during the quarter with a total of 18 holes for 3,796 metres completed. Most holes were drilled from the 025mRL decline position targeting the lode position down plunge of D Block at around 400 to 500m below surface.
Drilling has generally failed to identify strong lode material. No significant visible gold or assays have been seen to date. Although some lode alteration is present, it is mostly weak. Further exploratory drilling is planned from the 989mRL (‐11mRL) vent drive position.
Nine infill holes were drilled from the 105mRL and 80mRL cross‐cut positions to further test the C Block area. These holes were generally drilled within, and parallel to, the lode. WDUD0246 intercepted a spectacular visible gold intercept at 12 ‐ 12.2m downhole. This intercept is within the current lode zone at around the 100mRL and was around 4‐5m away from a previous visible gold intercept seen in WDUD0212. Logging has showed visible gold in two other holes. Assays are pending for these holes.

EXPLORATION SUMMARY
MOUNT MAGNET GOLD PROJECT (WA) (Ramelius 100%)
Ramelius continued exploration reverse circulation (RC) drilling during the quarter with 8,904m from 51 holes completed outside the optimized Galaxy cutback; encompassing the Saturn, Mars and Perseverance pits at Mt Magnet (Figure 4).
Exploratory drilling was completed around the historical Morning Star, Brown Hill, Reno, Vegas and Hesperus pits while reconnaissance drilling was completed at Bullocks (700m southwest of Morning Star) plus below the historical Hill 50 tails dumps to the north of Galaxy.
Ten RC holes were drilled adjacent to and below the Morning Star pit (GXRC0291 – GXRC0303). Better results include:
-
GXRC0297: 9m @ 11.5 g/t Au from 66m, including 4m @ 22.7 g/t Au from 67m
-
GXRC0303: 15m @ 1.28 g/t Au from 39m
Ten RC holes (GXRC1197 – GXRC1208) were drilled around the Bullocks Prospect located 700m southwest of the Morning Star pit. Encouraging results include.
-
GXRC1206: 6m @ 7.36 g/t Au from 60m
-
GXRC1207: 15m @ 5.37 g/t Au from 94m, including 1m @ 60.0 g/t Au from 99m
Limited deeper drilling was completed into the Mercury Lodes below the Mars Pit, ahead of mining earthworks commencing during the quarter. Better results returned include:
-
GXRC1196: 14m @ 2.35 g/t Au from 216m
-
GXRC1197: 24m @ 2.49 g/t Au from 186m
-
Incl: 1m @ 10.4 g/t Au from 187m and
-
+ 2m @ 13.9 g/t Au from 197m
A complete list of significant (>0.5g/t Au) drill intersections received this quarter is presented in Attachment 1.

SPARGOVILLE GOLD PROJECT (WA) (Ramelius 100%)
Wattle Dam Extensions
A geological re‐interpretation of the Spargoville Belt covering the area between the Wattle Dam Gold Mine and Eagles Nest (10km south of Wattle Dam) was completed during the quarter. Deeper exploratory RC drilling is scheduled to commence next quarter.
MT WINDSOR GOLD PROJECT (QLD) (Ramelius earning 60%)
Nightjar
Further encouraging rock chip results were received from the balance of samples collected and reported from Nightjar (G‐133) last quarter. Significant grab/rock chip sample results assayed up to 3.50 g/t gold, 38.0 g/t silver and 11.4% copper. Nightjar is located 2km north‐ northeast of the gold anomalous Plateau intrusive rhyolite breccia pipe where historical drilling by previous explorers returned encouraging drill intersections up to 10m @ 5.0g/t Au.
RC drilling and selected diamond drilling is scheduled to commence over Nightjar plus Plateau, Mt Redan, Mosquito Hill and Cardigan Dam next quarter (see Figures 5+6).

NEVADA PROJECTS (USA)
BIG BLUE JOINT VENTURE NEVADA (USA) (Ramelius and Marmota earning 70%)
==> picture [237 x 299] intentionally omitted <==
Figure 7: Big Blue and Angel Wing project locations in Nevada USA
RC drilling was completed at Big Blue during the quarter. Three holes were drilled for 580.6m, testing below the 56g/t Au surface rock chip response that was inaccessible during last quarter’s drilling campaign (Table 1).
Table 1: Big Blue drilling summary
| HoleId | Easting | Northing | F/Depth(m) | Az/Dip | Target |
|---|---|---|---|---|---|
| BBR11-05 | 506310 | 4387185 | 254.5 | -65/270 | Strike of56g/trockchip |
| BBR11-06 | 506310 | 4387185 | 147.8 | -60/207 | 56g/tAurockchip |
| BBR11-07 | 506156 | 4387177 | 178.3 | -65/270 | Anomalous soils>32ppbAu |
The drilling was targeting high grade Carlin Style vertical feeder structures below surface rock chip assays up to 56g/t Au. The drilling intersected interpreted Upper Plate siliciclastic rocks displaying an apparent shallow easterly dip of 20[0] . The siliciclastics overlie an interpreted Lower Plate limestone sequence. The limestones are exposed in outcrop 145m west of BBR11‐07 and are associated with a coherent plus 32ppb gold in soil anomaly.
The contact between the siliciclastics and the limestones is interpreted to represent the Roberts Mountain Thrust. Along the Carlin Trend the Roberts Mountain Thrust juxtaposes Ordovician to Silurian deep sea shales, siltstones and mudstones over Devonian shaley limestones. Gold mineralization is dispersed laterally within the porous decalcified shaley limestones below the Roberts Mountain Thrust, proximal to high grade feeder structures.
10
Gold in soil anomaly over the limestone sequence at Big Blue is consistent with this model for lateral dispersion and suggests anomalous gold mineralization may be developed within the limestones below the Roberts Mountain Thrust.
Assay results are awaited.
ANGEL WING JOINT VENTURE NEVADA (USA) (Ramelius and Marmota earning 70%)
RC and diamond drilling was completed at Angel Wing during the quarter. An aggregate 240.17m of HQ diamond core and 1,652.50m of RC drilling was completed to test below the known gold anomalous veins (including the DaVinci Vein reporting 3m @ 25.0 g/t Au in surface rock chips) and various strong induced polarization (IP) resistive trends.
A summary of the drilling completed is presented in Table 2 below.

By the end of September assay results had only been received from the epithermal bladed quartz carbonate Botticelli Vein observed in AW11‐C01. See Attachment 2 below.
The intersection, while disappointing displays elevated Ag:Au ratios. Coupled with the high level bladed quartz carbonate textures observed in the core potential remains for high grade gold mineralization to be discovered at depth. Trace element geochemistry will be examined once all the assay results are available to help guide further exploration drilling next year.
