HIGHLIGHTS

  • A further high grade intersection achieved at Milky Way in Mt Magnet (WA) of; � 12m at 3.05 g/t Au

  • Key Tanami Joint Venture (NT) tenements at Highland Rocks granted

  • Excellent Quarter-to-Date gold production (October & November only);

  • ~18,000oz produced at an AISC of ~A$1,060/oz

  • Maiden Ore Reserve at Blackmans Project near Mt Magnet of;

  • 244,000t @ 2.0g/t for 16,000oz

  • Ore Reserve additions at Kathleen Valley Gold Mine (WA) of;

  • 70,000t @ 3.5g/t for 8,000oz

Ramelius Resources Limited (ASX:RMS) is pleased to provide the following company update across the operations, project development and exploration areas of the business.

The final 3 holes of the second phase of Milky Way exploration drilling has returned a further ore grade intersection below the open pit itself. Milky Way is located 3.6km southwest of the Checker Mill at Mt Magnet in WA (refer Figures 1 & 2). Approximately 3,000m of infill resource definition drilling, in the area of the historical pit and starting below hole GXRC1345, will commence in mid-January 2016. Step-out exploration drilling further south is also planned for early February 2016.

In the Northern Territory, the Department of Mines & Energy has advised that three key exploration licences within the Tanami Joint Venture were granted on 18 November 2015. A Mine Management Plan has been submitted to the Department for approval ahead of field work commencing in March/April 2016 after the wet season.

On the operations front, gold production from the Percy and Mossbecker (Kathleen Valley) open pits continues to exceed expectations especially in terms of grade delivered from Mossbecker. As a result, the Checker Gold Mill at Mt Magnet has produced ~18,000oz at an AISC of ~A$1,060/oz for October & November. Despite an expected 10% decrease in mill throughput in December, ahead of a full SAG mill re-line in January 2016, the Company still expects quarterly production to be at the upper end of the Guidance range (23,000-25,000oz).

A maiden Ore Reserve for the Blackmans Project, some 30km north of Mt Magnet, has been produced following completion of a mining study. 244,000t @ 2.0g/t has been defined inside an open pit that is estimated to take 12 months to mine. Statutory approval processes are currently underway and Blackmans is expected to be included in the mining schedule in early FY2017.

Finally, further resource definition drilling has been undertaken at the Kathleen Valley gold mine, leading to additional viable open pits at Nil Desperandum and Yellow Aster North. The pits are relatively small, totalling a volume of 770,000bcm, with the combined additional Ore Reserve being 70,000t @ 3.5g/t for 8,000oz.

EXPLORATION

Mt Magnet Gold Mine – Milky Way (WA)

All assay results have now been received from the programme of ten deep exploration RC drill holes and two RC reentries completed at Milky Way last month. The drilling was targeting along strike, plus up and down dip of the previously reported 6m at 11.64 g/t Au and 7m at 11.29 g/t Au intersections (refer ASX Releases dated 14 September 2015 and 13 October 2015 respectively) and returned a bonanza grade gold intersection of 22m at 55.05 g/t Au from 112m (refer ASX release dated 2 December 2015). Further high grade gold mineralisation now includes:

� 12m at 3.05 g/t Au from 149m in GXRC1343

As with the previously reported high grade intersections, the gold mineralisation is associated with the newly discovered Milky Way Fault. Where the fault passes through the 50m wide (estimated true width) Milky Way Porphyry it manifests as a series of high grade (steeply plunging) mineralised shoots (refer Figures 3 to 5).

The broader mineralised porphyry interval (using a 0.1 g/t Au lower cut) reports as:

� 73m at 0.79 g/t Au from 149m, including 30m at 1.56 g/t Au in GXRC1343

The remaining two drill holes (not previously reported) failed to intersect the Milky Way Fault and did not return any significant mineralised porphyry intervals (see Table 1 below). The fault is interpreted to project into the footwall of the Milky Way Porphyry as you head south (refer Figure 3) and is therefore believed to be further west of drill hole GXRC1346. Drill hole GXRC1344 was drilled from west to east, mainly due to access restrictions on the east side of the pit, and this hole demonstrated that the far western portion of the porphyry is relatively barren away from the Milky Way Fault.

Milky Way resource definition drilling will commence in January 2016, while step out drilling will commence in February, 2016. The step out drilling will initially target the 1.8km southerly strike of the Milky Way Fault and include deeper drilling below the O’Meara pit, in addition to deeper reconnaissance drilling below the high grade intersections reported thus far below Milky Way (refer Figure 5).

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 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. True widths of the high grade shear zone remain unclear but are interpreted to be 50% of reported downhole intersections while the broader porphyry intersections are estimated to be 85% of the reported downhole intersections. Coordinates are MGA94-Z50.

Tanami Joint Venture (NT) - Ramelius 85%

Three key exploration licences within the Tanami Joint Venture were granted on 18 November 2015. The Highland Rocks ELs 27511 and 29829 plus the Officer Hills South EL27995 encompass over 1,200km[2] of highly prospective, yet under-explored, palaeo-Proterozoic stratigraphy located within 100km of the world class Callie Gold Mine (Figure 6).

A Mine Management Plan has been submitted to the NT Department of Mines and Energy for approval. It is anticipated field work will commence once all regulatory approvals have been granted.

OPERATIONS

Mt Magnet Gold Mine (WA)

Gold production from the Checker gold mill at Mt Magnet has reflected an excellent performance Quarter-to-date from both the Percy and Mossbecker open pits at Mt Magnet and Kathleen Valley respectively. A total of 18,000 ounces has been produced at an AISC of ~A$1,060/oz for the months of October and November 2015, leaving Ramelius well placed to achieve at the upper end of the production guidance range (Guidance released 28 October 2015: 23,00025,000oz at an AISC of A$1,250/oz).

Mill throughput is expected to reduce by approximately 10% during December, as is normally the case when the SAG mill liners are nearing end-of-life, with a full re-line planned for January 2016.

Note: Figures rounded to 1,000t, 0.1g/t & 1,000oz

Ore Reserve Commentary

Ore Reserves are based on the Mineral Resource model previously generated for Blackmans and reported in ASX Release dated 9 June 2015 ‘Blackmans (Mt Magnet) – Maiden Resource & Exploration Update’. Ore Reserves only utilise Indicated Resources and are reported above 1.0g/t.

Ore Reserve generation incorporates pit optimisation at A$1,500/oz, pit design and evaluation (refer Figure 7). Mining would be via conventional open-pit methods. The pit would be operated as a satellite operation from Mt Magnet, 30km south. Haulage of ore would be by roadtrain to the operating Checkers gold mill. Mine design considerations include geotechnical core drilling and external consultant recommendations, groundwater test drilling and consultant investigations, metallurgical test work, environmental studies, heritage and stakeholder consultations. Mining costs are based on recent rates at the Company’s Mt Magnet and Kathleen Valley operations. Milling costs are based on current Mt Magnet operating costs. A Mining Proposal will be submitted prior to the end of the year. Further detail is supplied below in Appendix B.

Ore Reserve Commentary

Ore Reserves are based on the Mineral Resource models previously generated for Kathleen Valley and reported in ASX Release dated 19 January 2015 ‘Maiden Ore Reserve boosts Kathleen Valley Gold Project’. Ore Reserves only utilise Indicated Resources and are reported above 1.5g/t.

A regularised, diluted version of the Mineral Resource model was created for mining optimisation, design and reporting (refer Figure 8). Mine design considerations include previously completed external geotechnical recommendations, groundwater investigations, metallurgical test work, environmental studies and mine scheduling. Additional dilution was added reflecting the flat lying nature of the deposits. Mining costs are based on recent actual and tendered mining rates at Kathleen Valley. Processing costs are based on current Mt Magnet milling and haulage costs. Mining approvals for the additional pits were granted with the initial project approval. Further detail is supplied below in Appendix C.

Disclaimer

No tonnage or grade estimates are available for the Exploration Targets outlined in Figure 5. The targets remain conceptual in nature as there has been insufficient deeper drilling to allow for any tonnage or grade estimates to be produced. Further, it is uncertain if additional exploration drilling will result in any exploration success. As a first pass, Ramelius proposes 200m spaced reconnaissance RC drilling to 200m below surface to scope the potential of the Extension Target to host significant mineralisation along strike of Milky Way in addition to selected deeper exploration drilling to scope the plunge projections of the high grade mineralisation reported below Milky Way to date. The drilling is scheduled to commence in February 2016.
