OPERATIONS
Mt Magnet Gold Mine (WA)
Mining by Ramelius at Mt Magnet has concentrated on the Galaxy mine area, approximately one kilometre from the processing plant, 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 in the 2017 financial year, whilst the Milky Way area is the current focus of mine life extensions and potential accelerated production from the 2018 financial year (refer Figure 2).

Figure 2: Mt Magnet key mining areas
The Titan pit cutback commenced in June 2016. Titan is located immediately west of the Saturn pit, completed in 2015. Titan mineralisation is hosted by a felsic porphyry and occurs as a large stockwork style orebody. The existing Titan pit was mined in 2000-2003, with recorded production of 920,000 tonnes @ 1.75 g/t for 51,700 ounces.
Mining of the Perseverance (Percy) open pit continued throughout the Quarter. The pit is now well below the base of the old pit and ore grades have improved significantly, helping to contribute to the high Quarterly mill grade. Significant underground stope voids are being encountered and have slowed mining rates as expected. Claimed high-grade ore mined was 176,589 tonnes @ 2.12 g/t for 12,028 ounces with mill reconciled production (including the addition of stockpiled low grade) of 271,911 tonnes @ 1.62 g/t for 13,037 ounces recovered.
Mill throughput was solid, even with a SAG mill reline being conducted in June and little oxide ore material being available for processing. Total mill production, including Kathleen Valley and Vivien ore, was 400,431 tonnes @ 2.79 g/t. The SAG mill reline saw a change to larger liners/lifters being used and this has led to increased mill throughput rates. It is currently believed these larger liners will also extend liner life, reducing reline frequency, although this won’t be confirmed until the next reline currently scheduled for mid-FY2017.

Figure 3: Ramelius geologists in Percy pit
Gold production (refer Figure 5) exceeded the Guidance range of 28-32,000 ounces, with 32,752 ounces of fine gold poured for the Quarter. Overall metallurgical recoveries for the Quarter were once again maintained at better than budget levels, with an overall recovery of 95%.
Cash costs for the period decreased appreciably to A$944/oz and AISC also dropped to A$1,145/oz (Guidance A$1,175/oz). This was primarily a result of higher overall gold production.
Production for the September 2016 Quarter is expected to be between 31,000 and 35,000 ounces. The midpoint of forecast production (33,000oz) is expected to be delivered at an AISC of A$1,100/oz. First stoping ore from Vivien is expected to be delivered during the Quarter along with continued good grades from both the Kathleen Valley and Percy open pits.

Kathleen Valley Gold Mine (WA)
Kathleen Valley continued to perform strongly. During the Quarter mining concentrated on the newer Yellow Aster North (YAN) and Nil Desperandum (ND) open pits. The Mossbecker and Yellow Aster Deeps pits were completed in late June 2016. Mining of YAN and ND will continue and be completed towards the end of the September 2016 Quarter. Ore haulage and milling will be completed in the December 2016 Quarter.
The project is strongly cash flow positive and has provided excellent open pit ore grades for the Company. Claimed ore mined for the Quarter totalled 132,382 tonnes @ 3.66 g/t for 15,557 ounces. At ND, waste prestripping was completed using the Cat-777 100 tonne mining fleet and the upper ore blocks were exposed and mined. Total material movement for the Quarter was 525,910 BCM.
==> picture [461 x 327] intentionally omitted <==
Figure 6: Nil Desperandum pit
Ore haulage continued throughout the quarter and Kathleen Valley attributed mill production was 109,571 tonnes @ 4.55 g/t for 15,436 recovered ounces. Milled grades continued to perform strongly. End of Quarter ore stockpiled at the mine site is estimated to be 67,768 t @ 3.13 g/t for 6,830 ounces.
6
Vivien Gold Mine (WA)
The first two full ore levels, the 360 & 340 levels, were completed during the Quarter and stoping commenced in July. Claimed ore mined (all development) for the Quarter was 19,116 tonnes @ 9.54 g/t for 5,864 ounces. Initial grade control modelling for the first stoping level shows both increased width and grade when compared to the original resource model, and hence a significant increase in contained gold. While it is still too early to assume this trend for the entire deposit, the signs look highly encouraging.
At the end of June, the decline had reached the 293mRL. The 320 level ore drive was well advanced and the 300 level cross-cut was being mined and close to intersecting the ore lode.

from Mt Magnet’s Perseverance (Percy) pit. Production Guidance was achieved in each Quarter, similar to the 2015 financial year.
Production for the 2017 financial year is expected to increase further to 135,000 ounces (refer Figure 10), with 65,000 ounces from Mt Magnet, 55,000 ounces from Vivien and 15,000 ounces from Kathleen Valley as it winds down. Production levels are expected to show a slight increase from H1 to H2 and there is a slight increase in overall grade as Vivien replaces Kathleen Valley feed which is offset by Titan & Blackmans open pit feed replacing Percy.

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). A 50m deep pit has been designed containing a Probable Ore Reserve of 244,000 tonnes @ 2.0 g/t for 16,000 ounces (refer ASX Release; ‘Company Update’, 16/12/2015) .
The project was further advanced with granting of the Mining Proposal and Mine Closure Plan Approval in April 2016. Engagement with the Shire and Main Roads also occurred and final approvals are expected in the September 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.
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 further detailed mine design and evaluation, geotechnical, hydrology and environmental work for the DMP’s Mining Proposal and Project Management Plan submissions. These documents plan to be submitted for approval in the September 2016 Quarter.

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 Milky Way and elsewhere within the larger Boogardie Basin target at Mt Magnet (refer Figure 12). The Company also undertook first pass reconnaissance soil, lag and vacuum sampling in the Tanami Joint Venture (ASX:RMS 85% / ASX:TYK 15%) within the Northern Territory.

Figure 11: Current Brownfields and Greenfields Exploration Projects location plan
Mt Magnet Gold Project (WA)
An aggregate of 11,886m of RC drilling (GXRC1374 – 1411 + 1421-1442 and a re-entry of GXRC0470) was completed at Milky Way and the larger Boogardie Basin porphyry targets during the quarter. The drilling at Milky Way comprised infill drilling between 150mbs and 200mbs. This was designed to improve confidence in the deeper Inferred Resource along with step out RC drilling below the maiden resource (>200mbs). Refer ASX Release dated 27[th] June 2016 – Further High Grade Gold at Milky Way – Mt Magnet WA for details.
MILKY WAY – INFILL DRILLING
The infill Milky Way drilling confirmed good continuity of mineralisation within the shallower, hangingwall felsic porphyry units and returned high grade gold mineralisation including, 17m at 5.61 g/t Au from 73m in GXRC1400 . This intersection is supported by 13m at 3.61 g/t Au from 50m in GXRC1394, approximately 45m below (refer Figure 13).
11
Significant infill drilling intersections (using 0.5 g/t Au lower cut-off) within the Milky Way resource (refer Figure 14) include:
-
3m at 21.68 g/t Au from 160m in GXRC1387, incl. 2m at 32.25 g/t Au
-
7m at 4.79 g/t Au from 156m in GXRC1399, incl. 1m at 21.70 g/t Au
-
20m at 5.85 g/t Au from 173m in GXRC1399, incl. 1m at 83.10 g/t Au
Complete drill hole assay data is provided in Attachments 1 and 2.
BOOGARDIE BASIN – STEP-OUT DRILLING
Step-out exploration drilling targeted favourable litho-structural repeats of the Milky Way Porphyry system at Stellar West, Brown Cow, O’Meara and Franks Tower (refer Figure 15).
Complete drill hole assay data is provided in Attachments 1 and 2. Based upon the limited intersections returned to date, true widths are estimated to be 65% of the reported down hole intersections at Stellar West and Brown Cow. True widths for mineralisation reported from Franks Tower are unknown at this stage. Mineralisation in all instances remains open at depth as well as along strike.
The mineralisation intersected at Stellar West demonstrates good bedrock plunge continuity, plunging 20[0] to the east and parallel to the main mineralised ore shoot mined within the Stellar pit. Significant intersections include:
14m at 3.96 g/t Au from 75m in GXRC1377
18m at 2.06 g/t Au from 47m in GXRC1426, incl. 7m at 3.00 g/t Au
At Brown Cow a single deeper RC hole was drilled behind the previously reported high grade intersection of 7m at 7.36 g/t Au from 47m in GXRC1363 (see ASX Release dated 4 April 2016 – Milky Way Exploration Update – Mt Magnet, WA). The new intersection shows excellent down dip continuity, returning:
4m at 9.64 g/t Au from 88m in GXRC1379
Drilling along strike from the Franks Tower pit delineated encouraging broad zones of anomalous gold mineralisation similar to the halo of gold mineralisation observed around Milky Way. Better results included:
127m at 0.37 g/t Au from 26m in GXRC1422
193m at 0.25 g/t Au from 44m in GXRC1424
As with Milky Way, the high grade gold mineralisation at Stellar West and Brown Cow is associated with sheared felsic porphyry – ultramafic rock unit contacts. Additional drilling will be undertaken at Franks Tower to test for higher grade mineralisation within the gold anomalous system. Encouragingly, the anomalous gold mineralisation remains open along strike at Franks Tower, down dip and down plunge at Stellar West and down dip and along strike at Brown Cow. These targets will be followed up with additional step out drilling during the 2017 financial year.

Tanami Joint Venture (NT) – Ramelius 85%
Reconnaissance (500m x 500m) surface soil, lag and shallow vacuum drill hole geochemical sampling was completed over the western half of the Highland Rocks ELs during the Quarter. While the vacuum drilling was largely ineffective because it struggled to penetrate through transported silcrete horizons, low order (2 – 5 ppb Au) surface soil and lag anomalies were returned from the sampling programme (refer Figure 16). Recognising the broad nature of the sampling grid, detailed regolith mapping and infill soil sampling will be required before any true assessment on the significance of the anomalies may be made.
Compilation of historical exploration data has also highlighted a significant open ended RAB/Aircore drill hole anomaly at Renton; located within the northern portion of the Highland Rocks ELs. Encouragingly the historical gold anomalous results extend over 600m strike and remain open with depth plus open to the west and east. Infill and strike extension drilling to determine the significance of the anomaly will be completed during the 2017 financial year.

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 high grade shear zone are interpreted to be 25-50% of reported downhole intersections while the broader porphyry intersections are estimated to be 85% of the reported downhole intersections for Milky Way and 65% for Stellar West and Brown Cow. Coordinates are MGA94-Z50. All holes are located below Milky Way unless labelled otherwise. Abn hole denotes hole was abandoned due to excessive deviation away from its intended target. Lighter font denotes intersections previously released to the ASX – see ASX Release dated 27[th] June 2016 – Further High Grade Gold at Milky Way – Mt Magnet WA

Reported significant gold assay intersections are constrained by the geological porphyry contact(s) using a 0.10 g/t Au lower cut and are reported using minimum 1m downhole intervals at plus.0.10 g/t gold, 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 of the broader porphyry intersections are estimated to be 85% of the reported downhole intersections. Coordinates are MGA94-Z50.

JORC Table 1 Report for Mt Magnet, RC Drilling and Tanami Soil Sampling
Section 1 Sampling Techniques and Data
| Criteria JORC Code explanation |
Commentary |
|---|---|
| Sampling techniques Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
Approximately 100grams of minus 80 mesh surface soil samples and +2mm to minus 6mm lag soil samples were collected on 500m centres during the Tanami soil sampling programme. At Mt Magnet potential gold mineralised intervals are systematically sampled using industry standard 1m intervals, collected from reverse circulation (RC) drill holes. Drill hole locations were designed to allow for spatial spread across the interpreted mineralised zone. All RC samples were collected and riffle split to 3‐4kg samples on 1m metre intervals. Diamond core (when reported) is half cut, with one half dispatched to the laboratory and the remainder retained for reference material Standard fire assaying was employed using a 50gm charge with an AAS finish for all RC chip samples. Trace element determination was undertaken using a multi (4) acid digest and ICP‐ AES finish. Soil samples gold and trace element analysis was by aqua regia digest with ICPMS finish |
