OPERATIONS
Mt Magnet Gold Mine (WA)
Open Pit
Open pit operations commenced at the Cosmos area with the Milky Way and Stellar West pits starting in July 2017. The new mining contractor, MACA Pty Ltd, made excellent progress with site layout and infrastructure completed and mining of 2.97Mbcm of mostly waste material. As expected, only minor ore production was recorded, with the deposits showing the typical Mt Magnet weathering grade depletion in the top 30 metres.
The quarter also saw the completion of the Titan pit by Watpac Civil & Mining contractors. The pit achieved design depth and produced some excellent grade towards the base. The pit was completed on the 18[th] September 2017 and Watpac Mining & Civil had completed demobilisation by the end of the quarter. Mine claimed HG ore was 856,861 tonnes @ 1.82g/t for 50,019 ounces. This compares to a pre-mining Ore Reserve of 1,150,000 tonnes @ 1.39g/t for 51,381 ounces, however an additional 428,414 t @ 0.76g/t of low grade ore was mined, bringing total claimed ore mined to 60,419 ounces.
A significant proportion of Titan ore remains to be milled with an end of quarter stockpile of 383,732 tonnes @ 1.12g/t for 13,761 ounces reported. This material will be fed while Cosmos ore production ramps up.
Claimed high-grade ore mined at Mt Magnet was 238,484 tonnes @ 2.33g/t for 17,876 ounces with Mt Magnet ore mill reconciled production (including the addition of stockpiled and Titan low grade) of 382,979 tonnes @ 1.79g/t for 20,367 ounces recovered.

Underground
Ore development continued at Water Tank Hill throughout the quarter. Ore drives were completed for the upper stoping panel in the 235, 260 and 290 levels (refer Figure 3). By the end of quarter, the 215 ore drive was well advanced in ore and the 195 drive close to intersecting ore. Grade control sludge drilling was completed in the upper levels.

Figure 3: Water Tank Hill development progress (grey) - oblique view to east
A raisebore slot rise was completed for the initial 235-260-290 stoping panel. Longhole drilling and stope production is expected to commence in October 2017.
Water Tank Hill development ore claimed for the Quarter was 12,871 tonnes @ 5.86g/t for 2,425 ounces.
Processing
The quarter saw a good grade reconciliation performance and the second best quarterly head grade recorded through the Mt Magnet facility (refer Figure 4). This delivered a strong total mill production result of 426,972 tonnes @ 2.64g/t for 33,836 ounces recovered at 93.4% recovery. A 6-monthly planned shutdown was also completed in July 2017 which included a SAG mill reline, conveyor repairs and an upgrade of the primary crusher structure.
Actual production exceeded the Quarterly guidance range of 28–32,000 ounces and resulted from higher grade ore being generated at Titan and Vivien. Cash costs for the period decreased to A$951/oz whilst AISC increased slightly from the previous quarter to A$1,209/oz.
Guidance for the December 2017 Quarter is expected to be between 30,000 and 34,000 ounces. The midpoint of forecast production (32,000oz) is expected to be delivered at an AISC of A$1,200/oz (refer Figure 5). Mt Magnet production will be reduced slightly due to completion of the Titan open pit and lower grade stopes being mined at Vivien.

Vivien Gold Mine (WA)
Claimed mined ounces at Vivien reached a new record due to establishment of a second stoping front and high stope grades. Stoping was completed on the 300 level and progressed significantly on the 260 north and 240 south levels (refer Figure 6). Ore development was mostly sourced from the 220 and 200 levels. Grade performance on the 200 level improved significantly after being somewhat weaker on the 220 level above.
The use of cemented rib pillars is progressing well, with all development waste being short hauled and used as cemented or loose fill in pillars and stopes.
Total claimed mined production (high and low grade) was 48,560 tonnes @ 10.34g/t for 16,140 ounces. Ore haulage continued throughout the quarter with Vivien attributed mill production of 43,993 tonnes @ 10.02g/t for 13,469 recovered ounces.

Deeper Exploration Drilling
An additional 7 deep underground diamond holes were drilled and 1 hole extended during the quarter for a total of 2,725m.
Two deep holes intersected a wide mineralised quartz vein in the lode position around 150 – 200 metres below the current mine plan. VVDD1064 returned 5.6m @ 5.20g/t from 330m and VVDD1067 returned 10.3m @ 9.20g/t from 291m. While these results are encouraging, most other results and the true widths (around 60%) have not yet demonstrated a viable deeper resource. A small number of further holes are planned and the lode will then be modelled and assessed.

Edna May Gold Mine (WA)
Ramelius acquired the Edna May Gold Mine on the 3[rd] of October 2017 from Evolution Mining Ltd (Evolution). The mine is located adjacent to the town of Westonia in Western Australia, 315km east of Perth.
Edna May is an operating open pit gold operation which was mined historically and by ACM Gold in the late 1980’s. Current operations (refer Figure 7) were commenced by Catalpa Resources in 2010, which merged with Conquest in 2011 forming Evolution.
The deposit has recorded production of over 1 million ounces, with over 500,000 ounces produced since 2011 under Evolution ownership. Annual production since 2011 has ranged from 66koz to 99koz. Historic underground mining between 1911 and 1948 recorded production of 570kt at a grade of 19.3g/t.

==> picture [485 x 116] intentionally omitted <==
Figure 7: Edna May Stage 2 open pit looking west
Gold is hosted by the Edna May Gneiss, a metamorphosed granitoid. Mineralisation occurs in a quartz vein stockwork throughout the Gneiss, forming a large low grade orebody. Higher grade, larger, arcuate veins arrays do occur and were the target of historic underground mining.
The Edna May mill is a 2.6 million tonne per annum (Mtpa) conventional CIL gold plant comprising of 2 stage crushing, SAG and Ball mill, gravity circuit and leach. Approximately 50% of Edna May gold is recovered via the gravity circuit and overall recovery is around 93%.
Ramelius Improvement Program
Mining will continue in the Stage 2 open pit where strip ratios are reducing and ore production is now at a higher rate than processing, allowing stockpiling of ore in various grade ranges to commence.
7
Since completion of the asset sale, Ramelius has moved quickly to put in place an improvement program for the operation which is aimed to both increase productivities and reduce costs. Initiatives already completed or underway include;
-
Streamlining of the management team and organizational structure
-
Replacement of Evolution employment policies with Ramelius’, which will lead to a cost reduction
-
Review of truck haul distances and whether “early” completion of tailings storage facility earthworks is warranted
-
Assessment of blasting practices to improve fragmentation which in turn increases mill throughput
-
Bringing forward underground drill positions to enable diamond drilling to start before the end of October 2017
-
Rationalise the underground set-up in terms of power and pumping infrastructure
Production Profile
Production guidance for the December 2017 Quarter is for between 19-23,000 ounces at an AISC of A$1,325/oz (refer Figure 8). Strip ratios in the Stage 2 open pit are expected to fall below 1:1 in the current quarter.
The remainder of the financial year is expected to see further decreases in strip ratios and AISC, whilst the production increases to 26,000 ounces in the June 2018 Quarter as mill head grades increase. The average AISC for the three quarters of Ramelius ownership in FY2018 is currently expected to be A$1,200/oz.

Figure 8: FY2018 Edna May Stage 2 Production Profile
Capital Requirements
A pre-existing underground decline has been refurbished immediately prior to the Ramelius acquisition, with completion of development for drill positions predicted by the end of November 2017. An underground diamond drilling program will commence in the December 2017 Quarter to assess geological and grade continuity of the high grade veins at depth. This underground program will be complemented by a surface drilling program that will in-fill drilling gaps below the Stage 2 open pit and form the first steps in assessing the viability of a Stage 3 open pit. The total capital associated with these drill programs is depicted below, in a consolidated view of group capital requirements, in Table 2.
8
PRODUCTION TARGETS
Group gold production is expected to increase in FY2018, to a new record total of 200,000 ounces and an AISC of A$1,100–A$1,200/oz, with the Quarterly breakdown by ore source shown below in Figure 9.

PROJECT DEVELOPMENT
Shannon Project (WA)
Based on drilling carried out through 2017 to date, a new, significantly larger, Mineral Resource of 581,000t @ 4.6g/t for 86,000 ounces was generated during the quarter (see ASX Release: 11 September 2017 ‘Shannon Resource & Exploration Update’).
Revised pit evaluation and design, and an underground scoping study have recently been completed and show a pit cutback and subsequent underground mine is viable. Further work including geotechnical diamond holes and rock property testing is now in progress, along with further encouraging exploration drilling down-dip and along strike (see Exploration section).
Morning Star Project (WA)
Geotechnical investigation was completed during the quarter. The Morning Star open pit will now be re-evaluated with updated wall design parameters and latest mining costs to generate a final pit design. Mine scheduling will then be carried out to identify the best fit for the updated Morning Star open pit, which is likely to follow on from the current Milky Way open pit as the base load pit at Mt Magnet.
EXPLORATION SUMMARY
Ramelius currently has a suite of Australian gold exploration projects at various stages of advancement, as shown on Figure 10. Mt Magnet was the focus of exploration drilling during the quarter.

Mt Magnet Gold Project (WA)
An aggregate of 8,692m of exploratory RC drilling (GXRC1677 – 1732) was completed at Mt Magnet during the quarter around Shannon, Zeus and Brown Cow. Ramelius also completed 29,678m of reconnaissance Aircore drilling (GXAC1476-1928) throughout the broader Boogardie Basin.
See Attachments 1, 2, 3 and 4 for a complete listing of significant drill hole intersections referred to in this report.
SHANNON EXTENSIONS
Infill resource development drilling continued at Shannon (GXRC0556 – 572) while step out exploratory RC drilling commenced during the quarter. Highly encouraging intersections were returned south of the resource (Shannon Ext. – see Figure 11) in addition to anomalous mineralisation intersected along the available 750m strike of the structural corridor (refer Figure 12). Better intersections returned to date include:
-
13m at 3.02 g/t Au from 92m in GXRC1690
-
5m at 11.43 g/t Au from 109m in GXRC1690
-
13m at 2.59 g/t Au from 103m in GXRC1710
-
4m at 5.42 g/t Au from 112m in GXRC1714
-
5m at 5.60 g/t Au from 104m in GXRC1719
South of the Shannon Resource the quartz reef is less pronounced and the structure is dominated by sericite-silica-pyrite alteration within the blue quartz eye diorite host porphyry. True widths are interpreted to be around 90% of the reported downhole intersections. Systematic infill RC drilling is underway (December 2017 Quarter) to scope for any expansion of the proposed Shannon pit and will test the mineralised structure to 200mbs.
Mapping and relogging historical holes around O’Meara and Theakstons, suggest a series of low angle faults (interpreted thrust ramps) with top block north movement may have allowed for the ingress of gold mineralisation throughout the larger target area south of the Shannon Resource. Deeper RC drilling will target these interpreted faults and their intersection with the Shannon structure during the December 2017 Quarter.

MORNING STAR DEEPS DRILLING
Final assay results are now available for the last of the Phase 1 Morning Star Deeps diamond holes completed last quarter, that is wedges L and M. Wedge M was stepped away from a highly encouraging intersection returned in the upper portion of wedge A, which intersected 3.75m at 15.58 g/t Au from 714m. Wedge M failed to enhance the interval but confirmed the presence of anomalous gold mineralisation and returned 0.37m at 1.17 g/t Au. Wedge L returned 2.13m at 8.19 g/t Au and 1.66m at 5.18 g/t Au where predicted within the Morning Star Deeps lode.
A detailed 3-D geological model of the entire Morning Star system (including the Morning Star Upper and the Evening Star Chert) is being created to help guide decisions on future targeting and drill testing within the Morning Star Upper and Deeps environment.
ZEUS PROSPECT
Infill RC drilling continued at Zeus during the quarter, with better results including:
-
27m at 1.22 g/t Au from 46m in GXRC1681
-
10m at 1.79 g/t Au from 33m in GXRC1684, and
-
21m at 1.27 g/t Au from 115m in GXRC1685
A large mineralised footprint has now been identified at Zeus. Future exploration will focus on modelling /targeting higher grade structures that may be feeding the mineralised envelope.
BROWN COW PROSPECT
Infill RC drilling continued at Brown Cow during the quarter, with better results including:
-
2m at 5.01 g/t Au from 36m in GXRC1702
-
1m at 110 g/t Au from 141m in GXRC1703
A further six holes were drilled to target the southern extension of the high-grade intersections. Assay results remain awaited.

Figure 13: Overview map of the Boogardie Basin highlighting maximum downhole gold ppm from drilling. The gold geochemistry is overlying a 1VD-RTP aeromagnetic image and the mapped/interpreted extent of the felsic porphyry intrusions; as constrained by the magnetic data and drilling. Litho-structural corridors favourable for the ingress and deposition of significant gold mineralisation are now being highlighted. The confluence of structures and/or their intersection with buried porphyry contacts represent primary targets for shallow plunging ore shoots to be developed. This interpretive 3-D modelling is ongoing.
REGIONAL AIRCORE DRILLING
Regional Aircore drilling continued throughout the Boogardie Basin during the quarter. The Aircore drilling targeted porphyryultramafic contacts in areas of ineffective historical drilling as well as shallow plus 100ppb gold in regolith anomalies and/or historical bottom of shallow RAB/Aircore anomalies (refer Figure 13). Encouraging Aircore drill results have been returned from several emerging areas, including infill drilling around the Apollo Porphyry, Stellar West, Brown Cow and the Shannon prospects. Anomalous results were also returned from selected traverses at O’Meara (see Figure 2) intersecting 16m at 0.34 g/t Au and Theakstons (located midway between O’Meara and Franks Tower in Figure 2) returning 24m at 0.79 g/t Au plus 17m at 1.15 g/t Au . Further infill drill testing will be completed over these target areas during the December quarter along with reconnaissance traverses over the southern (Milkwood) and western (Boogardie West) margins of Ramelius’ tenement package covering the Mt Magnet mine camp.

Yandan Gold Project (QLD) – Ramelius 100%
The Yandan North EPM is located 10km north and along strike of the abandoned Yandan gold mine which historically produced over 350,000oz of gold. Follow-up diamond drilling is scheduled to be completed during the December 2017 Quarter, subject to rig availability. Drilling will be completed below the previously reported encouraging reconnaissance intersections at the Firefly Prospect (including 28m at 0.27 g/t Au from 118m; 20m at 0.29 g/t Au from 244m and 21m at 0.29 g/t Au from 259m all in YNDD0002) (see ASX Release: 4 September 2017 “Exploration and Resource Development Drilling Update” and Figure 14).

CORPORATE & FINANCE
Gold sales for the June 2017 Quarter were A$52.0M at an average price of A$1,627/oz.
At 30 September 2017, the Company had A$83.3M of cash and A$12.8M of gold bullion on hand for a total of A$96.1M . This represents a A$6.2M increase from the June 2017 Quarter (A$89.9M). This increase resulted from a combination of positive cash flows from operating activities, development expenditure of A$16.1M and exploration activities of A$3.8M. With the acquisition payment of A$40.0M for Edna May and a reversal of favourable working capital movements, cash and gold on hand is expected to reduce over the December 2017 Quarter.
At 30 September 2017, forward gold sales consisted of 102,000 ounces of gold at an average price of A$1,721/oz over the period to 30 September 2019. The hedge book summary is shown below in Table 3.

The forward looking statements are based on current expectations, estimates, assumptions, forecasts and projections and the industry in which it operates as well as other factors that management believes to be relevant and reasonable in the circumstances at the date such statements are made, but which may prove to be incorrect. The forward looking statements relate to future matters and are subject to various inherent risks and uncertainties. Many known and unknown factors could cause actual events or results to differ materially from the estimated or anticipated events or results expressed or implied by any forward looking statements. Such factors include, among others, changes in market conditions, future prices of gold and exchange rate movements, the actual results of production, development and/or exploration activities, variations in grade or recovery rates, plant and/or equipment failure and the possibility of cost overruns. Neither Ramelius, its related bodies corporate nor any of their directors, officers, employees, agents or contractors makes any representation or warranty (either express or implied) as to the accuracy, correctness, completeness, adequacy, reliability or likelihood of fulfilment of any forward looking statement, or any events or results expressed or implied in any forward looking statement, except to the extent required by law.

Reported significant gold assay intersections (using a 0.5 g/t Au lower cut) are reported using 1m downhole intervals at plus 0.5 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 0.01 ppm Au. NSR denotes no significant results. True widths of the reported mineralised intersection remain unknown given the paucity of deeper drilling at this stage. Coordinates are MGA94-Z50. Abn hole denotes hole was abandoned due to excessive deviation away from its intended target.
- Denotes entire mineralised porphyry reported (using a 0.1 g/t Au lower cut and up to 4m of internal dilution). Coordinates are MGA94-Z50. Abn hole denotes hole was abandoned due to excessive deviation away from its intended target.

Reported significant gold assay intersections (using a 0.5 g/t Au lower cut) are reported using geological contacts or up to 1m downhole intervals at plus 0.5 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 0.01 ppm Au. NSR denotes no significant results. True widths of the reported downhole intersections are estimated to be +90% of the reported downhole intersections depending upon the lift of the drill holes. Coordinates are MGA94-Z50. Location of holes are annotated in the table. See the report text for a description on the annotation of the various lode positions. * Denotes hole re-entry

Reported anomalous gold assay intersections are constrained using a 0.40 g/t Au lower cut for the 4m composite interval, with up to 4m of internal dilution. Gold determination was by Fire Assay using a 50gm charge with AAS finishes and a lower limit of detection of 0.01 ppm Au. NSR denotes no significant results. EOH denotes end of hole depth. True widths remain unknown at this stage of exploration. Coordinates are MGA94-Z50.
