PERTH, AUSTRALIA–(Marketwired – March 29, 2017) –
THIS NEWS RELEASE IS NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE U.S.
Western Areas Ltd (ASX:WSA) (“Western Areas” or the “Company”) is pleased to announce the results from the Cosmos Odysseus Pre-feasibility Study (“PFS”), which demonstrates commercial viability of the Odysseus Project (“Project” or “Odysseus”) and the potential re-start of nickel mining operations at Cosmos. With the successful completion of the PFS, the Western Areas Board has approved the Project to progress to the Definitive Feasibility Study (“DFS”) stage.
The PFS base case findings indicate robust economic and nickel production metrics together with further significant upside opportunities, as well as a very low all-in sustaining cash cost of operations. The decision by the Board to commence a DFS underpins Western Areas’ strategy to develop a second operating region and thereby consolidate its position as a leading Australian nickel producer.
Highlights
Strong financial returns1
- Pre-tax NPV of $292m at US$7.50/lb, 0.75 AUD:USD exchange and 7.0% discount rate assumptions
- Surplus pre-tax net cashflow of $580m generated with a 3.5 year payback from production start
- Circa $100m per annum average free cash flow (pre-tax) post start up
Low cost operations
- LOM C1 unit cash costs of $3.21/lb (US$2.41/lb) including cobalt by-products and all in sustaining unit cash costs of $3.69/lb (US$2.77/lb)
- LOM cash breakeven price of $6.09/lb (US$4.57/lb) on an undiscounted basis
- Very low life of mine sustaining capital expenditure of $68m
Flexible start up and minimal early capital requirement
- Pre-production capital expenditure of $190-$210m including PFS, DFS and contingency costs
- Low near term capital requirements of $7m for CY2017 and $34m in CY2018, providing optionality on further commitments
- Benefits from significant existing infrastructure supporting the previous Cosmos operation
Physical parameters
- Initial 7.5 year mine life for total life-of-mine ore production of 4.9Mt at a grade of 2.3% nickel2
- First ore mined Q4, CY2020 and concentrate delivered in Q1, CY2021
- Average 12ktpa nickel in concentrate for a total of 87kt nickel metal
Significant upside potential
- Positive results from the recent resource drilling programme not yet factored into PFS results
- DFS to commence in Q2 CY2017 at a cost of between $5-7m, completion expected Q1 CY2018.
1 Unless otherwise stated, all cash flows are in Australian dollars and not subject to inflation or escalation factors. All years are financial years. All cash costs are calculated on a 100% payability basis. NPV and cashflow numbers quoted in this section use the lower contingency allowance of $9m.
2 Cautionary statement: The production target includes approximately 16% of material on a contained nickel basis as Inferred Resource, a lower level of geological confidence is associated with Inferred Mineral Resources. The majority of Inferred tonnes (85%) lie in the southern portion of the Odysseus North zone and are mined in year 2 and 3 of the Project. While not guaranteed, positive results from recent infill drilling indicates a strong likelihood that a significant proportion of the Inferred portion of the Odysseus North Resource will be upgraded to the Indicated category during the next resource estimation. The Company has concluded it has reasonable grounds for providing the forward looking statements in this announcement.

Overview
The PFS demonstrates that re-opening Cosmos and mining Odysseus will generate strong returns with potential for further growth given recent exploration results and other processing optimisations. Odysseus is expected to contribute a per annum average of $100m free cash flow (pre-tax) from 2022, at the assumed nickel price, with initial mine access activities being funded by existing cash on hand and expected future cash flows from the Company’s Forrestania operations.
One of the key advantages of Odysseus is the discrete nature of the capital profile which can be flexed or suspended at any time depending on the prevailing nickel price thereby retaining control over capital commitments.
Western Areas Managing Director Dan Lougher said that the PFS results demonstrate the healthy operational and financial characteristics of the Project.
“The positive results from the PFS, combined with the recent drilling success achieved within 18 months of acquisition, demonstrate Western Areas’ ability to accelerate and deliver value from the Cosmos acquisition,” Mr Lougher said.
“Odysseus represents Western Areas’ next mining operation and the results presented today show that a significant nickel operation can be established for substantially less capital outlay than a stand-alone greenfields development.”
“We are particularly pleased to have an operation that will have very low all-in sustaining unit cost at US$2.77/lb, but also a project that does not require a significant capital investment over the next two years, which provides optionality and flexibility in development decisions. Depending on market conditions, the Company also has the opportunity to complete early works where practicable and economic to do so.”
“We believe there are significant opportunities to drive further improvements in returns on this investment, including the potential for significant high grade resources below the existing deposit, as detailed in our announcement on 13 February 2017 of massive sulphide intersections of 5.3m at 15.2% nickel, including 3.4m at 22.0% nickel. The assay from this intersection is the highest grade over a reasonable width ever recorded at Cosmos from 446,000 prior assays under different ownership.”
“Odysseus is a core growth asset for Western Areas with exciting upside potential and progressing this to DFS stage will ensure that Western Areas is ready to leverage an upswing in nickel prices. Being a conventional underground nickel sulphide project, it is a great fit with our core skills and experience in hard rock underground mining and conventional nickel flotation at Forrestania,” Mr Lougher said.
Next steps
- Commence the DFS, leveraging our internal project skillset in developing conventional underground nickel sulphide projects;
- Upgrade a major portion of the Inferred Ore Resource category to the Indicated Category based on the recent resource de-lineation programme in the Odysseus North zone which is currently in progress;
- Further metallurgical work on fresh core, including batch and cyclic tests to confirm recovery and concentrate grade assumptions from previous tests;
- Potential further drilling of the high grade massive sulphide lenses below the disseminated resource to test continuity and potential for inclusion into the mine plan; and
- Continue to progress statutory approvals to be ready to commence dewatering once the DFS has been completed.

FORWARD LOOKING STATEMENT – INFERRED RESOURCE STATEMENTS:
The Company notes that an Inferred Resource has a lower level of confidence than an Indicated Resource and that the JORC Code (2012 Edition) advises that to be an Inferred Resource it is reasonable to expect that the majority of the Inferred Resources would be upgraded to an Indicated Resource with continued exploration. Based on advice from relevant Competent Person’s and the most recently completed drilling programme the Company has a high degree of confidence that the Inferred Resources for the Odysseus North deposit will upgrade to an Indicated Resource with further exploration work. Odysseus South is already 99.8% Indicated.
The Company believes it has a reasonable basis for making the forward-looking statement in this announcement, including with respect to any Production Targets, based on the information contained in this announcement and in particular, the JORC 2012 Mineral Resource for Odysseus as at October 2015, together with independent geotechnical studies, determination of production targets, mine design and scheduling, metallurgical test work, external commodity price and exchange rate forecasts and worldwide operating cost data.
