OPERATIONS
Mt Magnet Gold Mine
Mining continued at the Saturn, Mars and the recently commenced Perseverance (“Percy” – refer Figure 2) open pit. A total of 1,238,168 BCM’s was mined in the June 2015 Quarter, with mining at Percy progressing rapidly.
==> picture [469 x 169] intentionally omitted <==
Figure 2: Perseverance open pit cutback (looking east)

Percy is located at the top of the historic Hill 50 underground mine. The cutback commenced in January 2015 and will provide the major ore source for Mt Magnet for the 2016 financial year. Mining has been accelerated during the second half of financial year 2015, in order to access the higher grade, fresh ore which commences approximately 50 metres below surface level. The September 2015 Quarter will see increased access to ore at Percy as the main Hill 50 and Perseverance BIF lodes begin to be exposed.
Mining at the Saturn and Mars (refer Figure 3) open pits will be completed in the September 2015 Quarter, as the bottom 20 metres of ore is retrieved using the smaller 50 tonne capacity mining fleet.
==> picture [467 x 351] intentionally omitted <==
Figure 3: Mars open pit cutback (looking south)

Gold production (refer Figure 5) was within guidance, albeit toward the lower end, with 17,218 ounces of delivered gold poured and 17,915 ounces of gold sold for the period. Metallurgical recoveries were maintained at better than budget levels again this quarter, at 92%.
Cash costs for the period were A$800/oz and AISC increased to A$1,410/oz primarily as a result of lower ounces produced although increased costs associated with accelerated mining at Percy did influence the result. The increase in AISC through the initial phase of the Percy pit was expected and will remain higher than was the case in FY2015 until the second half of FY2016.

Production for the September 2015 Quarter is expected to increase with the impact of improving ore grades from the Percy pit and the initial deliveries of Kathleen Valley ore. The midpoint of forecast production (20,000oz) is expected to be delivered at an AISC of approximately A$1,350/oz.
Annual Guidance for Group gold production for the FY2016 full-year is expected to be ~99,000 ounces at an AISC of approximately A$1,250/oz, which demonstrates the expected improved cost performance in the second half of the financial year.

Figure 6: FY2016 Group Production Profile
Gold production is expected to increase quarter on quarter through FY2016 as shown in Figure 6, 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. Ramelius will be at a production run-rate greater than 100,000 ounces per annum by the March 2016 Quarter.

Kathleen Valley Gold Mine
Final permitting approvals and board approval was received in May, with the project commenced immediately thereafter.
Located 50km north of Leinster (WA), two open pits, Mossbecker and Yellow Aster, are currently planned and expected to produce a total of 418,000t @ 4.1 g/t for 56,000 oz (refer ASX Release, “Maiden Ore Reserve boosts Kathleen Valley Gold Project”, 19[th] Jan 2015).
In May and June 2015, significant progress was made, including;
-
Award of major contracts; Mining – WATPAC Civil & Mining Pty Ltd, Ore haulage - MLG OZ Pty Ltd
-
Appointment of key personnel including, project manager, geologists and surveyors
-
Construction of offices, fuel facility, workshop, dewatering dams, pipelines & explosives magazine
-
Mobilisation of mining contractor & equipment, site clearing and road construction
-
Initial RC grade control drilling program
-
Blasting & waste mining commenced in the last week of the quarter
RC grade control drilling results for the north end of the Mossbecker pit have been received and solid assay results confirm ore reserve expectations to date. Mining commenced on the 25[th] of June 2015 and ore mining started mid-July 2015 with haulage and processing expected to commence in August 2015.
Kathleen Valley high grade ore is expected to make an immediate positive impact on group gold production in the September 2015 Quarter.

Vivien Gold Mine
Board approval for the commencement of the Vivien decline was obtained in May 2015. The Vivien deposit is a high-grade, quartz vein hosted, lode gold deposit. Ramelius plans to mine a 3 year underground project, with an initial decline development phase of 6 months. A mining inventory of 451,000 tonnes at 7.6 g/t for 109,000 ounces is quoted (refer ASX Release, `Vivien Gold Mine Feasibility Completed’, 30[th] May 2014).
Preliminary site works were largely complete prior to full project Board approval and consisted of;
-
³
-
• Partial pit wall cutback above the portal location (100,000m )
-
Site earthworks including roadways, turkeys nest, bunding and ore pad
-
Office and workshop installation
-
Dewatering of the existing Vivien pit
Mobilisation of the selected mining contractor (PYBAR Mining Services Pty Ltd) occurred upon formal commencement, during the second half of the quarter. Completed work included meshing, shotcreting and support of the pit wall surrounding the decline portal position. As at 30 June 2015, the decline had progressed 53m and was fully within fresh, competent dolerite host rock.
==> picture [464 x 321] intentionally omitted <==
Figure 8: Vivien decline portal
First ore is expected to be intersected in November 2015, with ore haulage to the Checker gold mill at Mt Magnet expected to start in January 2016.

PROJECT DEVELOPMENT
Blackmans Gold Project
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 sub-parallel, 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.
After encouraging RC drilling programmes completed in December 2014 and February 2015, Ramelius announced a maiden Mineral Resource in June 2015 containing;
Table 3: Blackmans Mineral Resource (>1.0g/t)
| Resource Category | Tonnes Grade Au (oz) |
|---|---|
| Indicated Inferred |
361,000 2.6 30,000 129,000 2.3 9,000 |
| Total | 490,000 2.5 39,000 |
For full details refer to ASX Release, “Blackmans (Mt Magnet) – Maiden Resource & Exploration Update”, 9 June 2015.
Initial scoping suggests a viable open pit operation. Further mining and environmental studies and permitting processes are required and will be progressed during the remainder of 2015.

EXPLORATION SUMMARY
Ramelius currently has a suite of gold exploration projects at various stages of advancement, as shown on Figure 9.
Exploration during the quarter included Reverse Circulation (RC) drilling programmes at Mt Magnet (Blackmans) plus Kathleen Valley in WA and the Tanami Joint Venture in the NT. Aircore drilling was completed at Coogee in WA and diamond drilling was completed at both the Fraser Range in WA and the Tomalla Option in NSW. Field work also commenced over the Condobolin JV in central NSW with the completion of a 3D-IP survey.

Kathleen Valley (WA)
An aggregate 1,289m from 20 holes (KVRC0001 – 0020) was completed during the quarter along the Mossbecker Shear. Best result was 5m at 2.15 g/t Au from 39m in KVRC0016, located below the Yellow Aster pit shell.
Anomalous (plus 0.5 g/t Au) drill hole data is appended as Attachment 1.
Exploration drilling during FY2016 will focus on testing depth extensions and repetitions to the blind, fault offset Boris lode, located west and down-dip of the shallow Mossbecker deposit.

Tanami Joint Venture (NT) – Ramelius earning 85%
By early June 2015, the Central Land Council had consented to the grant of three Exploration Licence Applications (ELA) 27511, 27995 and 29829 within the Tanami JV. Subsequent to Quarter’s end, the Commonwealth Minister of Indigenous Affairs consented to allow the Northern Territory Mining Minister to proceed with the grant of these Exploration Licences. The locations of these ELA’s awaiting grant are shown on Figure 12.
During the quarter, Ramelius drilled 32 infill reconnaissance RC holes (SJRC0016 to SJRC0047) for an aggregate 2,532m within the granted Suplejack tenement (EL26625). The vertical holes infilled the drill spacing around the previously reported plus 10ppb Au interface anomaly, closing the hole spacing down to 250m (Figure 12). Encouragingly, the infill drilling confirmed strike continuity and extended the anomalous interface target (at plus 10ppb Au) to over 2km. A third phase of drilling is now planned.
Anomalous (plus 9ppb Au) drill hole data is appended as Attachment 2.

Condobolin JV (NSW) – Ramelius earning 80%
A detailed 3D-IP survey commenced over the Condobolin JV project towards the end of the quarter. Interpretation of the data is continuing.
Tomalla Option (NSW) – Option to acquire 80%
Ramelius completed two diamond drill holes during the quarter (TODD0001 and 0002) for an aggregate 259.9m during a 6 month option period at Tomalla, north of Gloucester in northern NSW.
The drilling was designed to confirm historical anomalous intersections. Both holes intersected conglomerates and sandstones with variable chlorite to intense silica-sericite alteration and disseminated to veined pyrite, arsenopyrite and pyrrhotite.
Drill hole details are included in Attachment 3. Assay results are awaited.
Fraser Range (WA)
A diamond tail was successfully completed during the quarter on RC hole (KNRC002). Final hole depth was 279.4m. The hole intersected a highly magnetic monzonite rock. The monzonite shows similar silica and selected major element contents to the Fraser Range “main gabbro”, based on published GSWA whole rock geochemistry, along with elevated copper assays (up to 100ppm Cu) but the monzonite appears
13
unrelated to the typical weakly magnetic leucogranite suites observed elsewhere throughout the Nornalup Terrane or the main gabbro of the Fraser Range.
No significant gold assays (>0.5 g/t Au) were returned from the drill hole and no further drill testing is proposed at this stage.
Coogee Extensions (WA)
Disappointing results were returned from a small programme of infill aircore drilling around the anomalous drill results reported last quarter. An aggregate 469m was completed from 10 Aircore drill holes (COAC0126 to COAC0135) west of the Coogee open pit, within ML26/477, located 100km southeast of Kalgoorlie in Western Australia.
Significant results (>0.10 g/t Au) are appended as Attachment 4.
CORPORATE & FINANCE
Gold sales for the June 2015 Quarter were A$27.9M at an average price of A$1,555 per ounce.
At 30 June 2015, the Company had A$34.9M of cash (including sold bullion awaiting settlement) and A$1.4M of gold bullion for a total of A$36.3M. This represents a A$0.5M increase from the March 2015 Quarter (A$35.8M) despite expenditure of A$5.9M on both development at Vivien & Kathleen Valley and greenfields exploration during the quarter.
In June 2015, Ramelius secured a financing facility with the Commonwealth Bank of Australia. The A$10.0M facility is intended to assist with the Vivien underground project capital development phase, if and when required. The facility is currently undrawn. In conjunction with the finance facility, an additional forward gold sales program has been put in place. Combined with earlier forward gold sales, and subsequent to 7,418 ounces delivered up to 30 June 2015, Ramelius will deliver a further 79,271 ounces of gold at an average price of A$1,570 per ounce to March 2017.
The Company has no corporate debt.
