Total material movement for the quarter was 8.8 million tonnes of material moved for 1.8 million tonnes of ore. The material movement was at the low end of expectations due to restricted loader and excavator availabilities. The mine schedule was running approximately one month behind schedule at the end of the year. Mined grades improved from 0.52% during the third quarter to an average of 0.55% during the fourth quarter, in line with expectations.
Mining activity for the quarter continued to be predominantly in the Central zone, delivering 81% of the ore mined. The remaining ore was sourced from the South and North pit zones. Access to the better quality ore in the South pit has been restricted due to geotechnical instability in the temporary pit wall between the higher central zone and lower south zone. Remedial works are underway. Reconciliation between mined grades and the new resource model was on expectations for the quarter and the mine, plant and maintenance rolling six week schedule and plans remain fully integrated into the operational production cycle.
Loader and Excavator availabilities continue to remain the key mining focus area for operational improvement. Two of the 120 tonne excavators were shut down for an extended period to assist in clearing a backlog of maintenance works on the machines. The third excavator is undergoing an extended shutdown during January 2013. Steady improvements in availability have been achieved post shutdown. Additional contractor excavator capability has been secured to assist in increasing material movement in the short term. The drilling and truck mobile fleets performed at expectations.
During the quarter 1.7 million tonnes of ore was milled, at an average head grade of 0.53% nickel and achieving an average recovery of 59%. The plant throughput was marginally lower than target due to the performance of the crushing circuit. The first crushing line is scheduled for major maintenance during the first half of 2013 with the new second crushing line performance improving during the quarter. Recovery performance remains in line with the grade recovery algorithm and the quality of ore feed to the plant. The de-sliming plant was fully operational for most of the fourth quarter with a minor shut down due to mechanical adjustments slightly impacting on the recovery performance. De-sliming continues to stabilise operations, recoveries and product qualities, as well as reducing reagent dosage rates and consequently costs.
Recovery optimisation test work for the quarter included an industrial test of new reagents in the plant. Early results are indicating improved recoveries and concentrate quality. The new reagents regime has been introduced into the plant and optimization of the process is continuing. MgO levels in the ore feed continue to be the most significant limiting factor on processing plant recoveries. Further test work is being undertaken in the laboratory and pilot plant as part of the ongoing recovery improvement program.
During the quarter Mirabela produced 5,291 tonnes of contained nickel in concentrate, 1,507 tonnes of contained copper in concentrate, and 91 tonnes of contained cobalt in concentrate. 5,044 tonnes of nickel in concentrate was sold to Mirabela's off-take partners, Votorantim Metais Niquel S.A. and Norilsk Nickel. One export shipment to Norilsk Nickel was completed during the quarter with steady deliveries to Votorantim continuing.
Sales for 2012 were split 56% to Votorantim and 44% to Norilsk. Both customers work cooperatively with Mirabela to decide on the prioritisation of concentrate deliveries. With the agreed focus on Votorantim deliveries over the last three years it is expected that the Norilsk Nickel off-take will extend beyond the end of 2014. The current Votorantim off-take will finish at the end of 2014.
Exploration & Studies
Exploration activity for the quarter was focused on tenement maintenance only.
The Company has appointed expert consultants, Optiro and Lycopodium, to assist with its operational optimisation and expansion studies. The Company's current priority is continued optimisation and low capital, incremental expansion. As such, the 9Mt pre-feasibility study has been re-prioritised behind this work with the pre-feasibility study now expected to be completed late in 2013.
Unit Cash Costs
(1) Average payability of 89%
The C1 unit cash cost improved for the third consecutive quarter, reducing from US$5.38/lb during Q3 to US$4.91/lb during Q4. The improvement from the third quarter was driven by: favourable tax credit adjustment (US$0.13/lb); write-back of stores provision created earlier in the year (US$0.09/lb); lower than normal mining waste strip-ratio for November and December (US$0.12/lb); continued cost reduction and optimisation initiatives; the BRL softening slightly against the USD (Q4 2012: 2.06 versus Q3 2012: 2.03); and lower sales, offset by marginally lower nickel production (down 3% from Q3).
The fourth quarter cash cost included a favourable adjustment relating to tax credits not previously claimed. As part of its optimisation program, the Company has been working with independent tax advisors to determine the claimability of certain Brazilian input tax credits on its production costs. The work was finalised during the fourth quarter and adjusted accordingly.
Cash and Debt
As at 31 December 2012, Mirabela held balances of cash on hand and on deposit of US$143.01 million. The decrease in cash on hand from 30 September 2012 (US$160.19 million) was driven by: an interest repayment of US$17.50 million on the senior unsecured notes; finalisation of nickel sales that occurred between February 2012 and July 2012 at an average finalisation price of US$7.69/lb compared to an average provisional price of US$8.13/lb (US$8.00 million); and capital, exploration and study costs of US$7.01 million. This cash outflow was offset by positive cash flow from operations.
As at 31 December 2012 the Company's issued share capital consisted of 876,582,736 ordinary shares. A balance of 4,150,000 unlisted options and 2,144,857 performance rights were outstanding. No options were exercised during the quarter.
2013 GUIDANCE (Please refer to the Disclaimer - Forward Looking Information below)
Mirabela is targeting production of 22,000 to 24,000 tonnes of nickel in concentrate for 2013. Production is expected to be stronger in the second half of the year due to improved access to higher quality South Pit ore during the second half of the year and scheduled maintenance work on the primary crusher during the first half of the year.
Unit cash costs are expected to average between US$5.00/lb and US$6.00/lb for the year. The spread in the average unit cash cost guidance is due to the large number of factors impacting on unit cash cost outcomes, including nickel price, copper price and the Brazilian Real / US dollar exchange rate. The Company will provide more specific unit cash cost guidance during the course of the year if possible.
Capital expenditure, exploration and study costs for 2013 is forecast at between US$40 million and US$50 million. Major items include: mobile equipment rebuilds; tailing storage facility wall lift; general sustaining capital; and capitalised mining costs. Exploration tenement holding costs and operational optimisation study costs will be charged to Other Expenses in the Statement of Comprehensive Income as incurred. The Company is not anticipating material expenditure on growth activities for 2013.
