MT MAGNET GOLD MINE
Mt Magnet performed well with higher mill throughput and gold production within guidance. Western Queen South high grade ore stocks were depleted during the quarter and head grade consequently decreased. However, with improved mill throughput, 18,916 ounces of gold were recovered, and 19,215 fine ounces of gold poured.

Figure 2: Mt Magnet Quarterly Production
The Checker mill processed 420,132 dry tonnes at a head grade of 1.58 g/t Au for the Quarter.
Mining in the Saturn pit saw improved ore grades mined as the cutback reached the base of the previously mined pit. Mining at the Mars pit was recommenced to schedule production effectively in line with the latest 2014/15 budget plan. Milled grade reflects the blending of fresh higher grade pit ore with stockpiled low grade oxide ore, at a 4:1 blend ratio, to achieve optimum throughput without damage to the SAG mill.
WESTERN QUEEN SOUTH OPEN PIT
Mining at the Western Queen South pit was completed in the March 2014 quarter. In the June quarter, the remaining ore was trucked to Mt Magnet and milled. Site clean-up and rehabilitation was mostly completed during the June quarter as per the approved mine closure plan.
3
COOGEE OPEN PIT
Mining at the Coogee pit was completed in the March 2014 quarter. Site clean-up and rehabilitation was also completed during the June quarter as per the mine closure plan. Ore haulage to the Burbanks mill continued throughout the June quarter, with haulage actually completed on 30[th] June 2014.
BURBANKS MILL
Milling of Coogee ore continued steadily throughout the quarter. Grades have remained high and mill production for the quarter was 44,360 t @ 4.76 g/t for 6,451 oz recovered, whilst fine gold poured was 6,207 ounces. Remaining Coogee ore stocks are lower grade (~3.5 g/t) and will be depleted in the September 2014 quarter.
PROJECT DEVELOPMENT
Vivien Gold Project
Acquisition of the Vivien gold project was completed on the 1[st] July 2014, following a final payment of A$5.5M late in June 2014 and which included a GST amount of A$1M that will be recouped at the end of July 2014.
Ramelius completed a bankable feasibility study (BFS) including detailed mine design, financial evaluation, geotechnical, metallurgy, environmental, hydrology and heritage work. Regulatory approval processes are well advanced with all major approvals received including the Mining Proposal and Project Management Plan. The Ramelius BFS was reviewed by an external consultant and no significant issues were raised.
The study envisages mining a Total Mining Inventory of 451,000 tonnes at 7.6 g/t Au for 109,000 ounces over a period of 30 months, after 8 months of underground development. The Total Mining Inventory is based on the Ore Reserve and a small proportion of Inferred Mineral Resources (for full details please refer to ASX Release ‘Vivien Gold Mine Feasibility Completed’, 30 May 2014).
Kathleen Valley Gold Project
During the quarter, Ramelius signed a Sale and Purchase Agreement with Xstrata Nickel Australasia Operations Pty Limited (XNAO), a subsidiary of Glencore plc, and with Giralia Resources Pty Limited (Giralia) to acquire 100% of the XNAO Kathleen Valley tenements and 100% of the tenements held by XNAO and Giralia as the participants in the Kathleen Valley and Mount Harris Joint Ventures. Ramelius will pay a total of A$4.05M for the purchase and expects completion to occur by the 31[st] August 2014.
The XNAO Kathleen Valley tenements are located 50km north of Leinster in Western Australia (Figures 1 & 3) and contain Mineral Resources of 130,000 ounces of gold in three deposits - Mossbecker, Yellow Aster and Nils Desperandum (for Mineral Resource details please refer to ASX release ‘Acquisition of Kathleen Valley Gold Project’, 10 June 2014).
Ramelius intends to complete further resource definition drilling within the next six months to enable the Company to upgrade resource confidence and complete mine planning studies. Scoping studies undertaken on behalf of XNAO indicate the potential for high grade open pit developments with low capital costs.

EXPLORATION SUMMARY
Exploration drilling focused at Vivien, Vivien Gem and Coogee during the quarter.
Vivien Deeps
An aggregate 1,515m from 5 holes (VVRC1000 to 1005) was drilled at Vivien to complete the programme started in the March 2014 quarter (refer ASX Releases dated 17[th] April 2014 and 29[th] May 2014). The drilling scoped for possible extensions to the hangingwall lode intersected in VVDD1005 (6.7m at 8.29 g/t Au) and returned encouraging hangingwall gold intersections up to 9m at 2.88 g/t Au from 127m, including 1m at 10.7 g/t Au in VVRC1000 (Figure 4). Assay results are tabled in Appendix 1.

Vivien Gem
The Company completed an aggregate 2,887m from 13 RC drill holes (VVRC1006 to 1018) to test the plunge of high grade mineralisation at Vivien Gem, located 2km north of Vivien (refer ASX Release dated 29[th] May 2014). Encouraging intersections included:
-
6m at 7.06 g/t Au from 212m in VVRC1011
-
10m at 6.56 g/t Au from 176m in VVRC1017, including 1m at 45.21 g/t Au from 180m
Complete drill hole results are compiled in Appendix 1.
Gold mineralisation at Vivien Gem is analogous to Vivien and is hosted by quartz-sulphide veining within a sheared dolerite unit. North of 6904950mN, the dolerite thins and is fault offset to the west. Only low grade gold mineralisation extends north of the fault. Further drilling is planned to test the interpreted plunge projection of the high grade gold mineralisation intersected to date (Figure 5).

Updated ASX Releases, ‘Tanami Farm in and Joint Venture Agreement’, 27 May 2014 and ‘Acquisition of Kathleen Valley Gold Project’, 10 June 2014, are attached below. These releases have been updated to comply with JORC requirements. Changes are largely related to Table 1 JORC 2012 Reporting Criteria.
TANAMI FARM-IN AND JOINT VENTURE AGREEMENT
Highlights:
� Farm-in deal secured over a 1,700km[2] prospective land package within the Tanami Complex – Northern Territory
The Directors of gold miner Ramelius Resources Limited, (ASX:RMS) are pleased to announce that the Company has finalised terms with explorer Tychean Resources Limited (ASX:TYK) for Ramelius to farm-in on a package of two granted Exploration Licences (ELs) and six EL applications in the Australian Northern Territory.
The package of tenements is located within 100km of Newmont’s plus 4.5 million ounce Callie gold mine within the Northern Territory Tanami Complex (Figure 1). The land package represents a unique opportunity to explore over 1,700km[2] of prospective Palaeoproterozoic stratigraphy within a significant yet underexplored gold province.
Farm-out and Joint Venture Agreement Terms:
-
Ramelius will pay Tychean $50,000 cash upon execution of the agreement to assist Tychean facilitate the grant of the Highland Rocks and Officer Hills South exploration licences within the land package
-
Subject to all necessary statutory and regulatory approvals plus the grant of the two Highland Rocks and Officer Hills South ELs Ramelius will commit to a minimum expenditure of $100,000 within 2 years
-
Ramelius may earn an 85% interest in the project by spending $500,000 within 3 years
-
Tychean will be free carried until a Decision to Mine at which time it may elect to contribute its interest or convert to a 1.5% NSR Royalty.
Background:
Research by Geoscience Australia* (circa 2006) included the application and interpretation of deep seismic transects throughout the Tanami region in the Northern Territory. The regional seismic transects enabled Geoscience Australia to model the crustal architecture within the province and to interpolate that known lode gold deposits within the Tanami may be associated with major crustal penetrating shear zones and antiformal thrust stacks, nested on deep seated thrusts propagating off the Proterozoic-Archaean basement detachment. Linear magnetic trends, interpreted as thrust faults, extend into the Tychean tenements (Figure 2) and may represent potential conduits for the ingress of gold mineralising fluids. Tychean’s tenement package was originally applied for in 2010 to 2011. Ramelius will now advance exploration over the tenements within this under-explored and highly prospective gold province.
Over 80 line km of prospective structural trends are believed to exist within the Highland Rocks ELAs alone. These trends will be the focus of detailed regolith/outcrop mapping plus rock chip sampling along with shallow vacuum and surface soil sampling programmes over the next 12 months. Results will be reported as they become available.

ACQUISITION OF KATHLEEN VALLEY GOLD PROJECT
Highlights:
-
Ramelius to acquire the high grade Kathleen Valley Gold Project in WA
-
Kathleen Valley project located close to the Company’s new Vivien Gold Project
-
Creates synergies for Ramelius’ integrated high grade WA gold development
Kathleen Valley Gold Project Acquisition
The Directors of Australian gold producer, Ramelius Resources Limited (ASX: RMS), are pleased to announce a further broadening of the Company’s gold operations in Western Australia.
Ramelius has signed a Sale and Purchase Agreement with Xstrata Nickel Australasia Operations Pty Limited (XNAO), a subsidiary of Glencore plc, and with Giralia Resources Pty Limited (Giralia) to acquire 100% of the XNAO Kathleen Valley tenements and 100% of the tenements held by XNAO and Giralia as the participants in the Kathleen Valley and Mount Harris Joint Ventures.
The XNAO Kathleen Valley tenements are located 50km north of Leinster in Western Australia (Figure 1) and contain a JORC (2012) Mineral Resource of 130,000 ounces of gold in three deposits - Mossbecker, Yellow Aster and Nils Desperandum (see Table 1).
Ramelius intends to complete further resource definition drilling within the next six months to enable the Company to upgrade the resources to Indicated, for use in future mine planning studies. Scoping studies undertaken on behalf of XNAO indicate the potential for high grade open pit developments with low capital costs.
Upon completion of the Sale and Purchase Agreement, the signing of ancillary Deeds of Assumption and Assignment plus a Nickel Offtake and Clawback Agreement with XNAO, Ramelius will pay XNAO A$3.645 million cash for 100% of its Kathleen Valley tenements. In addition Ramelius has agreed to pay A$405,000 cash to acquire 100% of the adjacent Kathleen Valley Joint Venture and Mt Harris Joint Venture. Collectively the package of three contiguous tenement groups will be referred to as the Kathleen Valley Gold Project.
Managing Director Ian Gordon said, “The acquisition of the Kathleen Valley Gold Project will add significantly to Ramelius’ recent acquisition of the Vivien Gold Project, enable cost reduction synergies across both projects and significantly build on the Company’s strategy to create a high yielding, positive cash flow mining business centred on its established Mt Magnet Milling Operations.”

Kathleen Valley Mineral Resource Summary
Resources are generated from 475 RC and diamond holes drilled by previous companies between 1984 and 2012. All resources are located on ML36/375. Drillhole density is typically 12.5m by 25m to 25m x 50m. Mineralisation occurs as shallow dipping silica-sericite sulphide lenses within a granitic conglomerate proximal to a shallow dipping fault contact with underlying mafic units. Split RC sub-samples and half core were assayed by Aqua Regia and Fire Assay methods. Gold was estimated within 3D lode shapes interpreted using a 0.5 g/t cut-off and Ordinary Kriging methods. Metallurgical testwork shows high recovery suitable for normal CIP/CIL processing and open pit mining methods are assumed. Previous economic studies have been conducted by earlier companies, including XNAO, and show viable open pit mining. Detailed information is given in JORC Table 1 below.
