MT MAGNET GOLD MINE
Production at Mt Magnet for the quarter saw gold output fall due to the failure of the ball mill drive motor. This was partially offset by milling of higher grade ore and resulted in mill production of 16,036 ounces of gold recovered and 16,753 fine ounces of gold poured.

Figure 2: Mt Magnet Quarterly Production
The Checkers mill processed 373,984 dry tonnes at a head grade of 1.52 g/t Au for the Quarter. The mill feed grade was the highest achieved to date, with a head grade of 1.73 g/t Au in December 2013.
Failure of the 1,650kW ball mill motor occurred on 9 November 2013. Four full days of milling were lost, after which a bypass circuit was enabled using the SAG mill only and allowing a reduced throughput. By 20 November 2013, a smaller capacity motor of 1,200kW was installed which allowed milling to resume at a throughput rate of around 85%. The original motor is being rebuilt and is expected to be reinstalled and operating in February 2014.
Mining continued to focus on the Saturn pit within the Galaxy area. Further steps were taken to separate and prioritise high grade ore availability during the period of reduced mill throughput. Historic Hill 50 tails material was also milled during the quarter to buffer the mostly fresh Saturn ore feed within the SAG mill. Western Queen South high grade ore was also milled during the quarter.
Total cash costs for the quarter were A$25.7M, with a further A$3.5M expended on capital being primarily a tailings dam lift (A$2.1M) and the Western Queen South haul road upgrade work (A$1.4M).
WESTERN QUEEN SOUTH OPEN PIT
Mining at Western Queen South continued throughout the quarter and although a wall failure interrupted progress in December 2013, good ore production was achieved. Ore is stockpiled at site before haulage to and processing at Mt Magnet.
3
Estimated ore production was 69,403 t @ 4.02 g/t for 8,972 oz with mining progressing into fresh, higher grade material. On 4 December 2013, a slip occurred on the western side of the pit wall beneath the ramp. Prism monitoring had shown movement in this area prior to the failure and no injury or equipment damage occurred. After geotechnical inspection a remediation plan was enacted. This involved mining into the failure area to remove unstable material, forming a flatter wall profile, sheeting with fresh waste rock and bunding the toe of the failure zone. By the end of the quarter the slip area was remediated and normal mining activity resumed.

Upgrade work to the haulage route continued throughout the quarter, in parallel with limited ore haulage operations. To date, haulage has been limited to the use of single trucks of 30 tonne capacity. A total of 30,967 t @ 4.62 g/t for 4,601 oz was hauled and ore stockpiled at the pit at the end of the quarter was estimated at 62,918 t @ 3.47 g/t for 7,019 oz. The use of larger road trains is expected to commence in February 2014, which will allow higher rates of ore movement from that time.
COOGEE OPEN PIT
Excellent progress was made at Coogee during the quarter with mining proceeding ahead of plan. The Stage 1 pit was completed to the 260mRL and mining of high grade ore commenced during the quarter. The second and final grade control drill campaign was conducted in early December 2013. Mining achieved estimated production of 64,539 t @ 3.92 g/t for 8,141 oz. Completion of mining is expected in the March 2014 quarter. Total capital expenditure at Coogee during the quarter was A$232K primarily being haul road upgrade work ($222K).

BURBANKS MILL
Toll milling was completed on 18 October 2013 and milling operations then changed over to Coogee ore. Milling commenced on lower grade supergene ore and switched to high grade main zone ore in November 2013. Grades have reconciled above estimated mined grades and mill production by the end of the quarter was 34,627 t @ 5.58 g/t for 6,094 oz recovered, whilst fine gold poured was 5,042 ounces.
Total cash costs for the quarter were A$6M, with a further A$0.5M expended on capital being primarily a tailings dam lift (A$0.4M).
PROJECT DEVELOPMENT
Vivien Gold Project
Ramelius undertook a diamond drilling campaign at Vivien in the December 2013 quarter. Drilling included 3 geotechnical HQ holes and 3 resource infill NQ holes. Results were similar to expectations with some excellent grades returned in high-grade areas. Drill core also displays the excellent ground conditions present in fresh lode material and surrounding dolerite host unit. Results are included in the Exploration Summary below.
A revised Resource model was in progress at end of the quarter and further mine evaluation work is planned for the March 2014 Quarter.
EXPLORATION SUMMARY
Exploration drilling was undertaken at Vivien and Coogee during the quarter. Total exploration and resource development expenditure for the quarter was $2.77M (incl. project generation of $107K).

AUSTRALIAN PROJECTS
Vivien Deeps
Encouraging high grade gold intersections have been returned from exploration drilling at the Company’s Vivien Gold Project, located 20km west of Leinster in the Eastern Goldfields of Western Australia.
The Company embarked on a programme of step-out exploration drilling at Vivien, in addition to the development drilling referred to above. The drilling programmes were initiated following the first payment of A$5 million to Agnew Gold Mining Company Pty Ltd for the acquisition of the advanced gold project, as announced on 3 October, 2013.
Assay results are now available for all the diamond holes (VVDD1000 to VVDD1018A), testing below the historical Vivien pit and the modelled north-eastern plunge extensions to the main lode. An aggregate 5,685.92m has been drilled by Ramelius since the first payment was made in October 2013 to acquire the project.
Better drill intersections returned to date include:
-
10.0m at 4.69 g/t Au from 360.0m in VVDD1001
-
5.40m at 8.28 g/t Au from 310.0m in VVDD1003
-
6.70m at 8.29 g/t Au from 241.6m in VVDD1005; and 6.50m at 30.4 g/t Au from 257.7m
-
2.57m at 18.16 g/t Au from 396.3m in VVDD1014 and
-
5.10m at 6.43 g/t Au from 182.9m in VVDD1017

Figure 5: Longitudinal section – Vivien gold project
The drill hole intersections include encouraging hangingwall mineralisation of 6.70m at 8.29 g/t Au in VVDD1005 (Figure 5). The hangingwall intersection compliments the main lode intersection of 6.50m @ 30.4 g/t Au within the same hole and confirms good continuity of mineralisation around historical drill holes.
6
It also highlights the potential for greater thicknesses of high grade gold mineralisation to be discovered below the Vivien pit. True width of the main lode intersections are estimated at 55-60% of the reported down hole width while true widths of the interpreted hangingwall splays are up to 90% of the reported down hole widths.
A table of anomalous results from the December 2013 quarter drilling programme is presented in Appendix 1.
Coogee Extensions
Three RC drill holes (CORC0007 – CORC0009) were drilled during the quarter for an aggregate 714m. The holes were designed to test for economic gold and copper mineralisation to the north of the Coogee open pit. Anomalous gold and copper assays up to 16m at 0.54 g/t Au and 0.12% Cu from CORC0008 have been returned. The copper mineralisation is manifesting as disseminated chalcopyrite and bornite. True widths are estimated to be 100% of the reported down hole intersections. The anomalous drill intersection in CORC0008 is associated with magnetite alteration and is located along the northern edge of a 200m diameter magnetic anomaly; as defined in the regional aeromagnetic data (Figure 6).
Previous gold exploration drilling results were reported in the June 2012 Quarter, but the significance of the gold-copper-magnetite association had not been fully investigated at that time. The reported significant gold intersection in CORC0006 returned 3m at 1.91% Cu.
A table of anomalous results from the December 2013 quarter drilling programme is presented in Appendix 2.

CORPORATE & FINANCE
Gold sales for the December 2013 quarter were A$27.8M at an average price of A$1,375 / ounce.
At 31 December, 2013 the Company held A$28.3M of cash and A$4.2M of gold bullion.
During the Quarter, the Company entered into a A$16M gold pre-pay facility with Deutsche Bank which was drawn down in early December 2013. Under the terms of the facility and consistent with the Company’s existing gold put option acquisition programme, Ramelius has purchased put options over 7,500 ounces of gold per month at a strike price of A$1,200 per ounce for the period from April to August 2014. The facility is secured against the Company’s Mt Magnet assets and will be fully repaid through the delivery of 1,492 ounces of gold per-month from January to August 2014.
As previously advised, the facility enables Ramelius to fast track the acquisition and potential pre-mining work at the high-grade Vivien Gold Project in Western Australia and provides flexibility for the Company to take advantage of potential opportunities to enhance the expanding Mt Magnet gold project via acquisition and/or development of a new satellite open pit.
