OPERATIONS
Mt Magnet Gold Mine (WA)
Mining by Ramelius at Mt Magnet has concentrated on the Galaxy mine area over the past four years consisting of open pit mining only. Water Tank Hill is an underground project currently forming part of the Company’s development pipeline, whilst the Milky Way area forms a key part of future resource growth and mine life extensions (refer Figure 2).
==> picture [359 x 262] intentionally omitted <==
Figure 2: Mt Magnet key mining areas
Mining of the Perseverance (Percy) open pit continued throughout the Quarter (refer Figure 3). Claimed high-grade ore mined was 185,167 tonnes at 1.46 g/t for 8,714 ounces with mill reconciled production (including stockpiled low grade) of 276,628 tonnes at 1.15 g/t for 9,270 ounces.
==> picture [274 x 213] intentionally omitted <==
Figure 3: Mining at Percy open pit
3
Mill throughput was reduced mainly due to the planned SAG mill reline in January 2016, with 380,397 tonnes processed at a 2.28 g/t head grade (refer Figure 4), as overall mill head grade continued to climb.
Gold production (refer Figure 5) was within the Guidance range, with 26,657 ounces of fine gold poured for the period. Overall metallurgical recoveries were maintained at better than budget levels again this Quarter, with a recovery of 95%.
Cash costs for the period were A$1,175/oz and AISC increased to A$1,196/oz (Guidance A$1,150/oz). This was primarily a result of slightly lower gold production, plus some increased costs associated with the SAG mill reline, when compared to the previous Quarter. Once again this Quarter, with additional high grade ore sources coming on-line, stock movement was a positive factor for the overall AISC.
Production for the June 2016 Quarter is expected to be between 28,000 and 32,000 ounces. The midpoint of forecast production (30,000oz) is expected to be delivered at an AISC of A$1,175/oz. Harder fresh ore from the Kathleen Valley gold mine is projected to restrict mill throughput to levels similar to the March 2016 Quarter, with throughput of 388,000 ore tonnes forecast. However a further increase in mill head grade to 2.6g/t is expected and will more than compensate when it comes to ounces produced.
Late in the June 2016 Quarter, it is planned that the Titan pit cut-back (refer to the Galaxy Mine Area in Figure 2) will be commenced to ensure overlap with the Perseverance open pit which is currently due to be completed in the September 2016 Quarter. The Titan pit has a waste pre-strip that will cost approximately A$1M in the June 2016 Quarter.

Kathleen Valley Gold Mine (WA)
At Kathleen Valley, open pit operations continued smoothly to plan with the Yellow Aster North (YAN) open pit commenced during the Quarter, joining the well advanced Mossbecker and Yellow Aster Deeps (YAD) open pits (refer Figure 6). The Nil Desperandum pit will be commenced in April 2016 with an expected prestrip cost of approximately A$1.5M.
Ore production jumped significantly for the Quarter as strip ratios in the Mossbecker and YAD pits dropped substantially. Claimed ore mined totalled 132,060 tonnes @ 4.63 g/t for 19,668 ounces. At YAN, the majority of pre-stripping was completed using the 100t mining fleet and the first ore blocks were mined. Total material movement for the Quarter was 519,356 BCM.
==> picture [467 x 356] intentionally omitted <==
Figure 6: Yellow Aster Deeps ore block
Ore haulage continued throughout the quarter and Kathleen Valley attributed mill production was 96,198 tonnes @ 5.12 g/t for 15,407 recovered ounces. Milled grade continues to reconcile above claimed mine grade. End of Quarter ore stockpiled at the mine site is estimated to be 51,265 tonnes @ 4.23 g/t for 6,979 ounces.
6
Vivien Gold Mine (WA)
Vivien saw the first substantial ore production occur with the advance of ore drives on the 360mRL and 340mRL. Overall development advance continued strongly with a decline advance of 250.5 metres and total development of 816.4 metres.
Claimed ore mined was 9,122 tonnes @ 6.72 g/t for 1,972 oz. Ore haulage to Mt Magnet commenced in February 2016 and attributed mill production was 7,571 tonnes @ 7.46 g/t for 1,779 recovered ounces.
A number of final infrastructure items were also completed in the Quarter and included completion of the top portion of the surface escapeway.
Widths and appearance of the lode can vary significantly and to date much of the 340mRL drive has been dominated by massive sulphides. However, the dip and strike shape continuity has been encouraging and a significant high-grade core lens has been encountered on both the 360 and 340 levels. Numerous wide, high-grade faces occur in the centre of these lenses (refer example below in Figure 7).

PRODUCTION TARGETS
==> picture [461 x 272] intentionally omitted <==
Figure 9: FY2016 Group Production Profile
Gold production is expected to increase through FY2016 as shown in Figure 9, due to an increasing mill head grade brought about by deliveries of Kathleen Valley and then Vivien high grade ore, plus improving ore grades from Mt Magnet’s Percy pit.

PROJECT DEVELOPMENT
Blackmans Gold Project (WA)
Blackmans is located 30km north of Mt Magnet, relatively close to the Company’s Checker processing facility on the outskirts of Mt Magnet (refer Figure 1).
Gold mineralisation at Blackmans extends over at least 350m strike and is associated with a number of sub-parallel, steeply west dipping quartz-sulphide lodes developed within high magnesium basalt host rocks. Lodes are generally 2-5m wide, from 10-20m below surface and vary between 60 and 300m in strike length. The lodes are overlain by transported laterite cover of 8-12m thickness, which contains a flat lying 2-5m thick, enriched gold zone near the base.
An Ore Reserve was released in December 2015 with a pit generating 244,000 tonnes @ 2.0 g/t for 16,000 ounces (refer ASX Release; ‘Company Update’, 16/12/2015). Activity for the Quarter consisted of further advancement of the Mining Proposal and Mine Closure process, plus engagement with the Mt Magnet Shire and Main Roads in respect of ore haulage approvals. All necessary statutory approvals are expected to be in place by the end of the June 2016 Quarter.
Water Tank Hill Project (WA)
The Water Tank Hill project lies 1.5km west of the town of Mt Magnet (refer Figure 2). The original deposit was located on a small hill, where the towns’ water storage tanks were previously sited. With the mining of the Water Tank Hill open pit, the hill was largely removed and the town water tanks relocated to a new site. The deposit is also located 300m west of the St George deposit which was mined by open pit and then underground methods between 2005 and 2007.
Gold mineralisation at the Water Tank Hill deposit occurs within a fold and fault thickened portion of the Banded Iron Formation host rocks (refer Figure 10).
Current Ore Reserves, released in September 2014, have a combined total for Water Tank Hill and St George of 335,000 tonnes @ 4.9 g/t for 53,000 ounces (refer ASX Release; ‘Resources and Reserves Statement’ 10/9/2015). Activity for the Quarter consisted of a preliminary assessment of the open pit and underground portal access ahead of commencement of the statutory approval processes.

EXPLORATION SUMMARY
Ramelius currently has a suite of gold exploration projects at various stages of advancement, as shown on Figure 11.
Exploration during the Quarter focused on drilling at Mt Magnet (Milky Way) and at Coogee (WA). An aggregate of 9,356m from 63 Reverse Circulation (RC) holes and a single diamond hole (with 141.5m of core) were drilled at Milky Way during the Quarter as part of the Company’s accelerated exploration drilling campaign around its active mine sites, while a reconnaissance programme of aircore drilling (1,760m) was completed at Coogee.
Subsequent to the end of the Quarter Ramelius advised Clancy Exploration (ASX:CLY) of its intention to withdraw from the Condobolin Joint Venture project located in central NSW (see ASX Release CLY: Ramelius withdraws from the Condobolin Gold project in NSW dated 1 April 2016). Ramelius retains no equity in the Condobolin Project.
Ramelius also advised its private joint venture partner of its intention to withdraw from the Cavanaghs Nickel Joint Venture, located 10km west of Mount Magnet. Ramelius retains no equity in the project.

BOOGARDIE BASIN – STEP-OUT DRILLING
Significant step-out exploration drilling intersections (using 0.10 g/t Au lower cut-off) targeting broad mineralised porphyry intervals below the resource development drilling and elsewhere throughout the larger Boogardie Basin include:
-
67m at 1.04 g/t Au from 126m in GXRC1347, incl. 32m at 1.62 g/t Au
-
� 74m at 0.82 g/t Au from 55m in GXRC1350, incl. 5m at 5.14 g/t Au � 48m at 1.03 g/t Au from 101m in GXRC1351, incl. 20m at 1.80 g/t Au
-

-
18m at 2.65 g/t Au from 54m in GXRC1364, incl. 1m at 45.30 g/t Au
-
19m at 4.50 g/t Au from 65m in GXRC1373, incl. 1m at 18.95 g/t Au
As previously reported the high grade gold mineralisation at Milky Way is associated with an anastomosing shear zone (Milky Way Fault) passing on or near the eastern contact of the 50m wide (estimated true width) felsic porphyry unit (Milky Way Porphyry) and subsidiary hangingwall felsic lenses (refer Figures 13 and 14).
The infill resource development drilling confirms significant stockwork gold mineralisation is associated with the altered felsic porphyry host rock at Milky Way. The prospective Milky Way Porphyry is characterised as a sericite-silica-pyrite altered fine grained felsic unit intruded into the basal ultramafic flow sequences that dominate the larger Boogardie Basin at Mt Magnet. The mineralised intersections returned to date are highly encouraging as they continue to demonstrate potential for a larger tonnage mineralised porphyry within the broader Mt Magnet gold camp.
The Company is now working towards a maiden Mineral Resource estimate for Milky Way expected to be completed in the first half of the June 2016 Quarter.
The Company also intends during the June 2016 Quarter to follow-up highly encouraging reconnaissance drill intersections reported away from the Milky Way Porphyry (refer Figure 15). Drilling will target high grade intersections including 7m at 7.36 g/t Au from 47m in GXRC1363 at Brown Cow (refer Figure 16), 19m at 4.50 g/t Au from 65m in GXRC1373 located west of the old Stellar pit and 5m at 4.89 g/t Au from 140m in GXRC1369, located south of the old Franks Tower pit.

Coogee Project (WA)
A reconnaissance programme of 69 vertical aircore holes (COAC0136 – 204) was drilled for an aggregate of 1,760m over the Coogee Beach prospect area during the Quarter. Coogee Beach is located 2km southwest of Ramelius’ mined Coogee pit on Lake Lefroy in Western Australia (refer Figure 17).
The drilling intersected a sequence of variably altered intermediate volcaniclastics interbedded with rhyolite porphyries below 19m of Tertiary lake sediment cover. Better drill results include 1m at 1.38 g/t Au from 27m to end of hole, 3m at 1.07 g/t Au and 2m at 0.74 g/t Au. Anomalous assay data (>0.1 g/t Au) is compiled in Attachment 1.
Deeper RC drilling will test below the anomalous intersections once a suitable lake rig becomes available.

Reported significant gold assay intersections (using a 0.1 g/t Au lower cut) are reported using 1m downhole intervals at plus 0.1 g/t gold, with up to 2m of internal dilution. Gold determination was by Fire Assay using a 50gm charge with AAS finishes and a lower limit of detection of 1 ppb Au. NSR denotes no significant results. True widths remain unknown until deeper RC can be completed. Vert. denotes vertical drill holes. Coordinates are MGA94-Z51.
