OPERATIONS
Mt Magnet Gold Mine
Mining continued at the Saturn and Mars open pits with the recently commenced Perseverance (“Percy”) open pit cutback also part of the mining schedule since early January 2015, with a total of 446,130 BCM’s mined in the March 2015 Quarter.
Percy is located at the top of the Hill 50 and Perseverance BIF lodes, which form the historic Hill 50 underground mine. The cutback commenced in January 2015, will take two years to complete and provide the major ore source for Mt Magnet for the 2016 financial year. Mining at Perseverance has progressed well with high productivity and lower unit mining costs being incurred in the upper oxide zones (refer Figures 2 & 3). Waste was short-hauled and tipped into the adjacent historic Jupiter open pit
==> picture [400 x 199] intentionally omitted <==
Figure 2: Perseverance open pit cutback (east side)
Lower grade oxide ore blocks (0.8-1.5g/t) are expected to be encountered as mining progresses down to the higher grade, fresh rock material approximately 50 metres below surface. For this reason, mining has been accelerated at Percy, in order to be at the level of better grade ore once mining is completed at the Saturn and Mars open pit early in the 2016 financial year.

The Mars pit provided the bulk of processed tonnes during the quarter, while a smaller mining fleet using 50 tonne articulated trucks was activated for mining to extend the base of the Saturn open pit. This fleet will enable a partial cutback and steeper and narrower ramp design to mine the bottom 20m of the pit (180-200 metre depth).
Processing of the resultant ore blend generated near record quarterly production with 22,655 ounces of gold poured in the March 2015 Quarter, based upon a mill throughput of 419,927 tonnes at a 1.84g/t head grade for 23,114 ounces recovered (refer Figures 4 & 5). Metallurgical recoveries were maintained at better than budget levels again this quarter, at 92.7%. A partial SAG mill reline took place in January 2015 and was accomplished on time and on budget, resulting in minimal impact on throughput which remained consistent throughout the quarter.

Mt Magnet production is expected to reduce somewhat as mining at the base of the Saturn and Mars pits slows. Oxide ore sourced from the Percy pit will assist milling throughput rates, however significant high grade ore production from the cutback is not expected for several months.
The midpoint of forecast production (18,500oz) and associated cash costs and AISC’s are shown in Figure 5, where the operation is forecast to post solid cash flows at current A$ gold prices. Annual Guidance for the Mt Magnet operation remains at 83,000 ounces at an AISC of approximately A$1,150 per ounce, whilst the overall Group gold production for the full-year is expected to be 88,000 ounces at an AISC of approximately A$1,100/oz.

PROJECT DEVELOPMENT
The high grade Vivien and Kathleen Valley gold projects are located 15km west and 50km north of the township of Leinster in Western Australia respectively (refer Figure 6). Both projects are situated close to sealed highway infrastructure.
The Vivien project was acquired from Gold Fields - Agnew on the 1[st] July 2014 whilst the Kathleen Valley project was acquired from Glencore subsidiary Xstrata Nickel Operations on the 1[st] September 2014.

Vivien Gold Project
The Vivien deposit is a high-grade, quartz vein hosted lode gold deposit. Ramelius proposes to mine it as a 3 year underground project with a total mining inventory of 451,000 tonnes at 7.6 g/t for 109,000 ounces (for further details refer ASX Release, `Vivien Gold Mine Feasibility Completed’, 30[th] May 2014). It displays an excellent gold recovery of 95%, with 60% gravity recoverable. All environmental approvals for the mine are in place.
In March 2015, Ramelius commenced preliminary surface works to prepare the project for full mining startup. These works include construction of an 8km dewatering pipeline to the Agnew gold mine, commencement of pit dewatering, surface site setup works and a partial open pit cutback to expose the portal position. The pit cutback involves a 100,000m³ trim of the east side of the Vivien pit (refer Figure 7) to access portal, vent fan and escape way locations in competent fresh rock on the south-east wall.
A formal Board decision on commencement of the underground decline is expected in the near future. It is also expected that surface works and underground commencement will progress from one to the other in a relatively seamless process. First ore will be accessed in late 2015. Financing options for the Vivien project are well advanced and details will be provided concurrent with project commencement.

Kathleen Valley Gold Project
A maiden Ore Reserve was generated and announced in January 2015, using a gold price of A$1,400 per ounce. Two open pits, Mossbecker and Yellow Aster, were designed and are expected to produce a total of 418,000t @ 4.1 g/t for 56,000 oz of gold. A Feasibility Study was completed in February 2015 and forecasts an AISC of $936 per ounce and undiscounted cash flow of $27.8M.
For full details of the drilling, Mineral Resource and Ore Reserve refer ASX Release, ‘Maiden Ore Reserve boosts Kathleen Valley Gold Project’, 19 January 2015.
The March 2015 quarter saw significant activity on project permitting, with submissions to government departments - the DMP, DoW, DER and DAA being progressed. Upon completion of the approvals process, Ramelius expects mine development at the Kathleen Valley Gold Project to commence quickly, with low capital startup costs. The Mossbecker deposit virtually extends to surface, meaning that there is no pre-strip required. At Yellow Aster, ore is reached at approximately 30m depth (refer Figure 8). Project commencement is scheduled for the June 2015 quarter, once final environmental approvals are granted.

EXPLORATION SUMMARY
Ramelius currently has a suite of exploration projects at various stages of advancement, both greenfields and brownfields as shown on Figure 9.
Exploration during the quarter focused on Reverse Circulation (RC) drilling programmes at Mt Magnet (Blackmans) in Western Australia and the Tanami Joint Venture in the Northern Territory. Aircore drilling was completed at Coogee in Western Australia. Diamond drilling at Fraser Range is now scheduled for completion during the June 2015 quarter.

Figure 9: Exploration Projects location plan
Blackmans (Mt Magnet, WA)
The Blackmans gold project is located on ML58/222, 30km north Mt Magnet. Ramelius conducted an infill drilling programme in February 2015 to follow-up its encouraging December 2014 drilling results.
Gold mineralisation at Blackmans extends over 350m strike and is associated with a shallow surficial transported laterite and a number of N-S striking, sub-parallel steeply dipping lodes hosted in oxidised ultramafic schists and clays.
A further 29 RC holes (BMRC0019 to BMRC0047) were completed for 1,957m. Reportable gold intersections above 0.5g/t were recorded for every hole. Highlight lode intersections (downhole width) include:
-
5m @ 4.65 g/t Au from 12m in BMRC0020
-
7m @ 2.86 g/t Au from 32m in BMRC0025
-
4m @ 15.51 g/t Au from 38m in BMRC0026
-
5m @ 10.04 g/t Au from 19m in BMRC0037
-
13m @ 2.31 g/t Au from 34m in BMRC0037
The near surface laterite gold zone also recorded several significant intersections, including:
- 5m @ 3.87 g/t Au from 3m in BMRC0022
9
-
11m @ 3.17 g/t Au from 6m in BMRC0033
-
6m @ 2.83 g/t Au from 6m in BMRC0039
For a full list of intersections and details of the drilling refer ASX Release, ‘Further High Grade Gold Intersected at Blackmans’, 9 March 2015.
Resource modelling has commenced with independent review of in-house block models to be carried out in accordance with standard Company practice. A maiden Mineral Resource is expected to be announced in the June 2015 Quarter. This will be followed by economic evaluation and Ore Reserve generation. Blackmans is at an early stage with respect to environmental and related technical studies, and if proved economic, will typically require 6-9 months before mining can be commenced.
Deeper RC and diamond drill testing to scope the northerly plunge projection of the East Lode (refer Figure 10) is planned during the June 2015 quarter.

Tanami Joint Venture (NT) – Ramelius earning 85%
The Tanami Joint Venture with Tychean Resources Ltd (ASX: TYK) progressed well during the quarter. Final copies of Mineral Exploration Agreements covering Highland Rocks (ELA27511 and 29829) plus Officer Hills South (ELA27995) in addition to the Groundrush (ELA27921), Mt Solitaire (ELA27997) and Groundrush South (ELA28493) applications were received from the Central Land Council. The locations of these ELA’s awaiting grant are shown on Figure 11.
During the quarter, Ramelius drilled 15 reconnaissance RC holes (SJRC0001 to SJRC0015) for an aggregate 1,206m over the granted Suplejack tenement (EL26625). The vertical holes were spaced 500m apart as a first pass drill test.
The Suplejack drilling was designed to scope for subtle base of unconformity anomalous geochemistry along the interface between the deformed and highly prospective Proterozoic Tanami Group stratigraphy and the overlying post deformation Ordovician basalt lava flows. Figure 12 highlights the thickness of the overlying basalt flows and attests to the targeting concept, where previous exploration over the project had failed to penetrate through the barren overburden.
10
Encouragingly, anomalous geochemical results have been returned for the drill hole assays received to date. The peak anomalous geochemical result is 2m at 27 ppb Au from 58m in SJRC004. Results from the adjacent hole SJRC003 are awaited. Unfortunately no anomalous gold (>10ppb Au) was recorded elsewhere in the drill holes. Nonetheless, compilation of the data is continuing and given the broad 500m spacing between the holes and the potential for depletion within the underlying weathered Tanami Group rocks the absence of any plus 0.5 g/t Au intersections is not considered discouraging at this stage. Trace element data is awaited. Trace element geochemistry and ASD (alteration logging) determination on fresher bottom of hole RC chips will assist in defining any bedrock trends worthy of further investigation. Infill drilling will be considered once all the gold and trace element results are available.
Anomalous (plus 10ppb Au) drill hole data is appended in Attachment 1

Black contours show the depth of unmineralised basalt cover. Yellow contours highlight an anomalous (plus 10ppb Au) interface trend between SJRC004 and 14 (over 1km), with results awaited from SJRC003.
Coogee Extensions (WA)
An aggregate 1,104m was completed from 27 Aircore drill holes (COAC0099 to COAC0125) west of the Coogee open pit, within ML26/477, located 100km southeast of Kalgoorlie in Western Australia.
Better results from the Aircore drilling included 4m at 2.76 g/t Au and 4m at 0.87 g/t Au. Mineralisation remains open to the north beyond the previously reported RC intersection of 23m @ 0.38 g/t Au and below historical, shallow, ineffective drilling. ASD (alteration mapping) determinations are currently being completed on the drill cuttings, prior to any follow-up drilling being planned. Significant results (>0.25 g/t Au) are appended in Attachment 2.
