“The September 2015 Quarter was an excellent performance by the operations team, returning the Company back above the 20koz mark with the FY2016 year Guidance in turn upgraded to 104koz. Having both the new operations in production is certainly exciting for Ramelius and the Percy pit at Mt Magnet is starting to mine better grades around the old Hill 50 underground stopes. We are also hopeful of further positive results at the Milky Way project this coming Quarter”, Managing Director, Mark Zeptner said today.

OPERATIONS
Mt Magnet Gold Mine (WA)
Mining continued at the Percy, Saturn and Mars open pits. A significant milestone was achieved with the completion of mining at the 200 metre deep Saturn pit, after 4 years of continuous production. Saturn ore production for the Quarter totalled 125,207 t @ 2.18 g/t for 8,767 contained ounces. Claimed high-grade ore production for the pit since commencement totalled 2,467,457 t @ 1.52 g/t for 120,748 ounces. This compares favourably to the June 2011 Ore Reserve of 2.08 Mt @ 1.5 g/t for 103,000 ounces.

Figure 2: Completion of mining at Saturn open pit
A total of 683,617 BCM’s was mined in the September 2015 Quarter from the 3 pits. The Mars open pit will be completed in the December 2015 Quarter. Increased access to the major Hill 50 & Perseverance BIF lode zones in the Percy pit will also occur in the December 2015 Quarter.
Mill production was excellent at 461,433 tonnes at a 1.80 g/t head grade (refer Figure 3), rebounding strongly from the June 2015 Quarter, with high throughput achieved and good grades available from the Mt Magnet and Kathleen Valley ore sources.
Gold production (refer Figure 4) was well above guidance, with 23,637 ounces of delivered gold poured and 22,871 ounces of gold sold for the period. Metallurgical recoveries were maintained at better than Budget levels again this Quarter, at 93%.

Production for the December 2015 Quarter is expected to increase with the impact of improving ore grades from the Percy pit and further delivery of Kathleen Valley ore. The midpoint of forecast production (24,000oz) is expected to be delivered at an AISC of approximately A$1,250/oz.
PRODUCTION TARGETS
==> picture [468 x 257] intentionally omitted <==
Figure 5: FY2016 Group Production Profile
Gold production is expected to increase Quarter on Quarter through FY2016 as shown in Figure 5, due to an increasing 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. The over-performance in the September 2015 Quarter, combined with a higher forecast for the December 2015 Quarter now means that previous full year FY2016 Guidance is expected to be exceeded. Previous Guidance of 99,000 ounces at an AISC of A$1,250/oz is effectively replaced with 104,000 ounces at an AISC of A$1,200/oz.
Kathleen Valley Gold Mine (WA)
The Kathleen Valley gold mine progressed smoothly throughout the Quarter. Mining is proceeding on Budget and ore production was strong with 82,498t @ 3.68 g/t for 9,747 ounces mined from the Mossbecker pit, which reached a depth of 20 metres.
Grade control is being conducted as a number of campaigns using light RC drilling and results have been highly encouraging. Grade control drilling is currently generating slightly less tonnes, at higher grades for overall ounces similar or better than Ore Reserve.

Ore haulage commenced on the 17[th] of August with milling following immediately. At the end of the Quarter mill production was 44,476t @ 3.91g/t for 5,425 recovered ounces. End of Quarter ore stockpiled at the Mossbecker ROM is estimated to be 34,794 tonnes.
Additional drilling has been conducted at the Nil Desperandum and Yellow Aster North resource areas. Results are encouraging and further drilling, modelling and evaluation is being undertaken and potential for adding two small pits is currently thought likely.
Vivien Gold Mine (WA)
Vivien underground development continued throughout the Quarter. The decline advanced 473 metres (70 metres vertical) during the Quarter and progress is approximately 20% ahead of schedule. Total development was 667 metres. Ground conditions in the host dolerite are generally very good.
The Quarter saw all significant site surface infrastructure completed. The primary ventilation raisebore hole was completed in early September and the primary ventilation fan was installed at the end of the Quarter (refer Figure 8). Several infrastructure items, including the ventilation fan, are carried over from the Wattle Dam underground gold operation.

Subsequent to the end of the Quarter, the first cut of ore was mined and hauled to the surface (refer Figures 9 & 10). Ore development will gradually ramp up as the main ore levels are reached, with road-train haulage and milling commencing in early 2016 following bitumen sealing of the Vivien mine road - Leinster highway intersection.

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.
Gold mineralisation at Blackmans extends over at least 350m strike and is associated with a number of subparallel, 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.
Work completed during the Quarter included application for a Miscellaneous Licence over the access route, completion of flora & fauna surveys, hydrogeological investigation drilling and water flow testing. Two geotechnical diamond holes were commenced at the end of the Quarter. Completion of technical studies and mine design is required before an Ore Reserve can be reported, expected in the December 2015 Quarter.

EXPLORATION SUMMARY
Ramelius currently has a suite of gold exploration projects at various stages of advancement, as shown on Figure 12.
Exploration during the Quarter included Reverse Circulation (RC) drilling programmes at Mt Magnet (Blackmans and Milky Way) and the Cavanaghs Joint Venture (abutting Mt Magnet) plus the Tanami Joint Venture in the NT. An aggregate of 3,954m from 18 RC holes was drilled during the Quarter. The drill hole information summary table and JORC Table 1 are presented as attachments to this report.

Figure 12: Exploration Projects location plan
Blackmans Gold Project (Mt Magnet, WA)
A single 222m deep exploration RC hole was completed at Blackmans during the Quarter. The RC hole was designed to test under the high grade Western Lode intersection of 10m at 15.76 g/t Au. The drill hole could not extend the Western Lode intersection but did return encouraging gold mineralisation along the Eastern Lode position, intersecting 5m at 4.70 g/t Au from 206m, including 2m at 10.64 g/t Au from 209m. Refer ASX Release dated 14 September, 2015.
Milky Way Gold Project (Mt Magnet, WA)
The Milky Way gold project is located 3.6km southwest of the Checkers Mill at Mt Magnet (Figure 13) and represents an exciting new porphyry gold exploration target. Five holes were drilled at Milky Way during the Quarter as part of a larger 10 hole, 2,376m reconnaissance programme targeting a number of buried porphyry and banded iron formation targets proximal to the mill. Highly encouraging results were returned from the Milky Way drill holes (see ASX Releases dated 14 September, 2015 and 13 October 2015) including the following significant (>0.5g/t Au) high grade intersections (refer Figure 14):
-
6m at 11.64 g/t Au from 189, including 2m at 33.4 g/t Au in GXRC1328
-
7m at 11.29 g/t Au from 232m in GXRC1336
10
Subsequent to the end of the September 2015 Quarter, a 2,500m RC drilling programme commenced at Milky Way. The aim of the drilling is to further scope the strike and dip continuity of the mineralized porphyry within the northern 400m of the +800m long porphyry that has been modelled to date (Figure 15). Drilling will include a re-entry of the northern most hole (GXRC1334) that failed to penetrate the main porphyry unit and adequately test the northern strike extension of the target. Deeper drilling is proposed to further test the dip continuity of the newly discovered high grade mineralisation reported during the Quarter. It is also intended to complete a series of 50-100m spaced step out drill holes to test the modelled porphyry southwards.

Figure 15: Isometric image of the Milky Way Porphyry (looking northwest).
The porphyry has been modelled over 800m strike to 340mbs, based upon historical shallow drilling plus recent gravity and magnetic inversion modelling. The modelling serves to highlight the paucity of deeper drill testing into the mineralised porphyry. The image also shows the proposed December 2015 Quarter step out drilling into the northern half of the porphyry. The cluster of mineralisation to the south of the Milky Way pit represents the eastern limit of the Andromeda pit (see Figure 13 for location reference). Mineralisation at Andromeda sits within the hangingwall of the Milky Way Porphyry and is wholly hosted by ultramafic rocks. Future drilling will also test the porphyry west of the Andromeda pit.
12
Tanami Joint Venture (NT) – Ramelius 85%
Early in the Quarter, Ramelius advised Tychean Resources Limited (ASX:TYK) that it had met its earn in expenditure commitment and had acquired an 85% interest in the Tanami Joint Venture. Tychean retains a free carried 15% interest in the Joint Venture through to any decision to mine.
The Joint Venture partners still await the grant of the six Exploration Licence Applications (ELA’s) highlighted in Figure 16.
Ramelius drilled seven holes for an aggregate 1,356m within the granted Suplejack tenement (EL26625), during the Quarter (refer Figure 17). Six of the holes were angled RC, drilled 100m apart to provide important geological information along the sheared contacts of the various rock units (intersected during the reconnaissance drilling programmes), below the +2km striking gold anomalous interface anomaly.
Encouragingly the drilling confirmed the southern extension of the gold interface anomaly. Low order gold anomalism (+10ppb Au) was returned where it intersected a graphitic schist unit. The graphitic schist unit also returned elevated portable XRF trace element determinations up to 0.18% Cu and 56ppm As, suggesting the unit may be a preferential host where its structurally thickened around the fold closure further south. Detectable gold anomalism (2-5ppb Au) was returned on or near the eastern dolerite/siltstone contact and near the western sheared pelite/siltstone contact, further attesting to the prospectivity of the larger Suplejack target area.

Condobolin JV (NSW) – Ramelius earning 80%
Work during the Quarter progressed with the planning of an RC drilling programme designed to test a number of chargeable IP anomalies returned from Ramelius’ recent 3D-IP survey over the project area. The drilling will commence once all statutory approvals have been granted.
Cavanaghs JV (WA) – Ramelius earning 70%
Cavanaghs represents a newly signed farm-in and joint venture agreement targeting massive nickel sulphide mineralisation within a large intrusive mafic sill complex located 10km west of the Mt Magnet township. Ramelius may earn up to 70% interest in the project from a private company by sole funding $2 million in exploration expenditure within 4 years.
During the Quarter, Ramelius drilled one angled RC hole into a strongly conductive EM anomaly but failed to intersect any anomalous nickel sulphides (>0.1% Ni). An 8m thick graphitic shale unit adequately explained the source of the conductive anomaly.
Detailed mapping and surface soil/rock chip sampling over the larger intrusive sill complex is planned for the December 2015 Quarter.
Tomalla Option (NSW) – Ramelius withdrawn
No significant (>0.5g/t Au) mineralisation was returned from the diamond drilling into the Tomalla project reported last Quarter. No further exploration is planned and the property has been returned to the vendor.

CORPORATE & FINANCE
Due to the increasing demand of regulatory requirements and ongoing growth of Ramelius, the roles of Company Secretary and Chief Financial Officer will be separated into two positions. This will enable the current incumbent Mr Dom Francese, who has diligently held both roles since Ramelius was listed on ASX in March 2003, to focus primarily on his Company Secretarial responsibilities and the Corporate Governance requirements of the Company. As a result, current Financial Controller Mr Simon Iacopetta has been promoted to Chief Financial Officer effective 1 November 2015. Mr Iacopetta is a Chartered Accountant who has 13 years in industry and joined Ramelius in March 2011.
Gold sales for the September 2015 Quarter were A$35.8M at an average price of A$1,565/oz.
At 30 September 2015, the Company had A$36.5M of cash (including sold bullion awaiting settlement) and A$2.7M of gold bullion on hand for a total of A$39.2M. This represents a A$2.9M increase from the June 2015 Quarter (A$36.3M) despite expenditure on capital development at Vivien (A$5.0M), Kathleen Valley (A$0.2M) and greenfields exploration (A$1.2M).
The A$10M financing facility secured with the Commonwealth Bank of Australia (CBA) in June 2015 remains undrawn.
At 30 September 2015, the forward gold sales program put in place in conjunction with the finance facility requires Ramelius to deliver a further 71,520 ounces of gold at an average price of A$1,570/oz over the period to March 2017. Additional forward gold sales totaling 6,900 ounces at an average price of A$1,624/oz have been taken out with deliveries out to the end of January 2016.
The Company has no corporate debt.

Reported gold assay intersections (using a 0.1 g/t Au lower cut) are reported using 1m downhole intervals at plus 0.1 g/t Au with up to 4m of internal dilution. Gold determination was by Fire Assay, using a 50gm charge with ICP-MS finishes and a lower limit of detection of 0.01 g/t Au. NSR denotes no significant results. True widths of the high grade shear zone remain unclear but are interpreted to be 25-50% of the reported downhole intersection and are estimated to be 85% of downhole intersections within the broader mineralised porphyry (pry) or banded iron (BIF) units. Coordinates are MGA94-Z50. Abn denotes hole abandoned due to excessive deviation
