Details
Panoramic Resources Limited (“Panoramic”) is pleased to release the results of its recently completed Scoping Study for the Mt Henry Gold Project. Since acquiring a 70% interest in the project from Matsa Resources Limited (“Matsa”) in July 2012, Panoramic has advanced a number of key work streams for the Project, reported here as the Mt Henry Scoping Study December 2012. A number of value enhancement opportunities have been identified which Panoramic believes could add significant further value to the Project. Panoramic is targeting the completion of a Bankable Feasibility Study (BFS) by Q4 2013.
The preferred scenario is to mine from three open pits (Mt Henry, Selene and North Scotia) with ore processed through a centrally located facility. Mining costs are based on market rates provided by a Western Australian open pit mining contractor who was supplied with production schedules and rock property information. A 2.5Mtpa gravity–flotation–leach processing facility was chosen as the optimum mill configuration and capacity based on Whittle optimisation of the three proposed open pits and metallurgical recoveries of 92% were used, based on previous test-work. Key Scoping Study outcomes are provided in Table 1.

Geology & Mineralisation
The Mt Henry Project is located at the southern end of the Wiluna–Norseman Greenstone belt of the Eastern Goldfields of Western Australia. Whilst the greenstone rocks from the Norseman region can be broadly correlated with those of the Kalgoorlie–Kambalda region, they form a distinct lithology which is bounded on all sides by major regional shears.
The Mt Henry Resource is 1.9km long, 6–10 metres wide and dips 65-75 degrees towards the west. The host rock is predominantly banded iron formation with minor meta-basalts and dolerites. Sulphide minerals range from trace to 10%. The predominant sulphide is pyrrhotite with minor pyrite, arsenopyrite, chalcopyrite and marcasite.
The host rock of the Selene Resource is also a banded iron formation which is intruded by numerous dolerite sills. The footwall contact is characterised by metamorphic sedimentary schist and the hanging wall by the overlying dolerites of the Woolyeener Formation. The Selene mineralisation extends for 1.3km along strike and extends 550 metres down-dip at a shallow angle of around 20 degrees. The mineralisation thickens in the central part of the Resource up to a true thickness of 35 to 40 metres.
The North Scotia Resource covers a strike length of 600 metres within Achaean mafic rocks of the Woolyeenyer Formation. The Woolyeenyer Formation is host to the auriferous quartz veins that have been mined in the Norseman district continuously for 80 years. Gold mineralisation is hosted by laminated quartz veins that dip at around 70[0] towards the west. Sulphides present include pyrite and galena.
Mining
The schedules used in the Scoping Study are based on JORC compliant Indicated and Inferred Resources for Mt Henry, Selene and North Scotia (refer Appendix 1). Mining is based on production from the three open pits, using contract mining. Two cutbacks are planned, one in Mt Henry and one for Selene. The average life of mine waste to ore stripping ratio across all the pits is 5 to 1. Conceptual pit shells were optimised at a gold price of A$1,500/oz using Whittle software. A breakdown of the open pit mining inventory is shown in Table 2. Figures 3 and 4 below show the conceptual pit shells for Mt Henry and Selene optimised at a gold price of A$1,500/oz. Historic drilling at Mt Henry intercepted a parallel zone of mineralisation in the hanging wall of the orebody. This zone has not been included in either the Resource estimate or economic evaluations and represents upside to the project. The Resources at Mt Henry, Selene and North Scotia remain open at depth.

Processing
GR Engineering Services Ltd (GR) undertook a review of historic cominution and metallurgical test-work. A 2.5Mtpa processing plant was selected as the optimal throughput rate. As some gold is associated with sulphide minerals, the currently proposed flow-sheet assumes ore will be ground to a P80 of 75 micron prior to flotation with the concentrate re-ground in an Isa Mill prior to leaching. The flotation tail will also be leached to maximise overall recoveries. Historic metallurgical test-work indicates that overall recoveries of 92% can be achieved with the proposed flow-sheet, and potential exists for higher recoveries subject to further test-work (planned for Q1 2013). A summary of the proposed flow-sheet is shown in Figure 5.

Operating Costs
Open pit mining costs were based on estimates provided by a Western Australian mining contractor, who used the proposed production schedules and rock property information (eg. hardness and abrasion) to provide mining cost estimates. Mining is based on conventional drill and blast on 5m and 10m benches with a conventional 100t excavator loading 100t dump trucks. Process operating costs were estimated by GR. Site power is assumed to be sourced from a diesel fired power station. A summary of the operating costs is shown in Table 4.
Table 4 – Operating Cost Summary
| Item | Unit | Amount |
|---|---|---|
| Mining | A$/t ore | 15 |
| Processing | A$/t ore | 29 |
| Geology + OH&S + Enviro + Admin | A$/t ore | 4 |
| TOTAL | A$/t ore | 48 |
| TOTAL | A$/oz payable | 927 |
Value Enhancement Opportunities
Panoramic has identified a number of opportunities which could provide significant value enhancement to the Mt Henry Project. The Company will investigate these opportunities as part of the BFS which is underway and due for completion in Q4 2013. Opportunities include:
-
Recovery – GR has indicated that recovery rates higher than 92% are possible. GR Engineering has indicated that recoveries of 94.5% could be achievable based on the proposed flow-sheet. The potential for this increased recovery will be confirmed by the metallurgical test-work planned in early 2013;
-
Power – the Scoping Study is based on using a diesel fired power station. If an alternative power source such as gas is available, power costs may be significantly reduced;
-
Resource upgrade – the drill program planned in Q1 2013 will target depth extensions to each of the Resources;
-
Parallel zones – historic drilling at Mt Henry intercepted mineralisation in the hanging wall adjacent to the Resource. These zones have not been included in either the Resource estimates or the economic evaluations. As this mineralisation falls within the current A$1,500/oz pit shell, the inclusion of these zones could enhance project economics;
-
Financing options – the Company will investigate the opportunity for contractors to build, own, and operate certain infrastructure;
-
Optimisation – work will be undertaken to optimise costs, production rates, mining schedules and the process flow-sheet as part of the BFS work; and
-
Magnetite – previous drilling has intercepted broad zones of magnetite rich Banded Iron Formation (BIF). The Company will investigate the potential for production of a magnetite concentrate.
Identified Risks
A number of key risks have been identified that may impact (either positively or negatively) on the economics of the Mt Henry Project. These risks include, but are not limited to:
-
Gold price
-
Foreign currency exchange rates
-
Capital and operating costs
-
Processing optimisation and recoveries
-
Project financing terms
-
Regulatory approvals

Limitations of the Mt Henry Gold Project Scoping Study
The Scoping Study which has been undertaken is, by its nature, not as reliable or certain in its outcomes as a Pre-Feasibility Study or Feasibility Study. As further modeling of the Resources and the Project is to be undertaken and the Scoping Study updated, the Study is not a definitive indication on how, or if, the Mt Henry Project will be developed. The Scoping Study (inclusive of the cost estimates contained within it) is subjected to a range of sensitivities, qualifications, assumptions and risk factors, which could affect the Project’s development. Capital costs are estimated to a sensitivity of +/-35%, however future changes in assumptions, such as processing and/or mining, may result in differing estimates which may fall outside this range. There is also a range of statutory approvals which are required before Project development can commence.
