Mirabela Nickel Limited - Quarterly Activity Report for the Period Ended 31 December 2010


Number of shares: 491,561,237

PERTH, Australia, Jan. 27 /CNW/ - Mirabela Nickel Limited ("Mirabela" or the "Company") is pleased to announce its unaudited fourth quarter results for the period ended 31 December 2010.


  • Production of 3,676 tonnes of nickel in concentrate for the quarter (Full Year:10,375t)
  • Sales of 3,104 tonnes of nickel in concentrate for the quarter (Full Year: 9,956t)
  • Break-through plant performance with average nickel plant recovery of 60% for the quarter (December average:  62%)
  • Plant throughput of 1.2Mt of ore for the quarter, above nameplate capacity (108%)
  • Total material mined for the quarter of 9.1Mt (Full Year:29.1Mt)
  • Continued decrease in unit cash costs to US$6.27/lb for the quarter; expected to continue with increasing production levels (Full Year: US$7.00/lb)
  • Mirabela strengthened the Board with the appointment of Geoff Handley and Ian McCubbing as non- executive directors


Ramp up of the Santa Rita operation continued during the fourth quarter. The operation is expected to reach an annualised full capacity of between 23,000 to 25,000 tonnes of contained nickel in concentrate per annum in 2012.  The focus for 2011 will be on the completion of the open pit pre-strip and the expansion of the processing plant to 7.2 Mtpa.

Mirabela is currently updating its NI 43-101 Technical Report and will provide production guidance for 2011 at the end of March 2011. January production has been restricted by mechanical problems with the SAG mill motor which are expected to be resolved during early February.  The estimated impact on January production is approximately 700t of nickel which maybe either partially or fully recovered during 2011. The first shipment of concentrate to Norilsk Nickel was successfully loaded during January.


Since commencing operations the project's strong safety performance has continued with one lost time injury for the fourth quarter.

The Lost Time Injury Frequency Rate for the year was 1.1, an outstanding result for the first year of operations and well ahead of the Brazilian mining average. The implementation of safety training and safety improvement programmes is continuing.

* The primary difference between the grade mined and the grade processed is due to the additional processing of lower grade material (not classified as ore) whilst the ramp up of the mining operation is catching up to the processing plant. 


The improvement in the mining operations seen during the third quarter 2010 carried through to the fourth quarter with record material movement achieved during the quarter of 9.1 million tonnes.

During the fourth quarter a total of 924,000 tonnes of ore was mined at an average nickel grade of 0.55%. The South Pit production increased during the quarter with the mining of good quality ore with minimal fines. The mining team continued their focus on waste removal to open up the strike length of the open pit, which will provide more mining flexibility and is critical for the ongoing ramp-up to the targeted full mining production capacity of 55 Mtpa material moved.

The planned expansion to the mining fleet was completed during the quarter with six hired CAT 777 trucks, three purchased CAT 785 trucks, a purchased Atlas Copco DML drill rig, two hired Bucyrus 37HR drill rigs and two hired CAT D9 Dozers added to the fleet, whilst the order was placed for four Komatsu Dozers with delivery in the first quarter of 2011.


Break through plant performance was achieved during the quarter with above nameplate throughput and a step change in recovery performance.

During the quarter a total of 1.2 million tonnes of ore was milled at an average recovery of 60% for the quarter, with plant throughput improving to 108%. The blending of low grade ore into the mill feed continued. Despite the low grade feed, the plant achieved average recoveries of 62% for December.

The improved recovery performance is a direct result of operational and technical improvements in reagents, grinding and the flotation regime. Material which previously recovered poorly is now achieving acceptable levels of recoveries. A pilot plant test program has been completed to determine the preferred process flow changes to provide further improvements to nickel recovery. The results have confirmed the opportunity to achieve higher recovery through mechanical separation of the fines and Mirabela is planning to install a de-sliming circuit by the end of 2011.

During the quarter a total of 3,676 tonnes of contained nickel in concentrate, 980 tonnes of contained copper in concentrate, and 62 tonnes of contained cobalt in concentrate were produced.  All production continued to be within contract specifications and 3,104 tonnes of nickel in concentrate was sold to Mirabela's domestic customer, Votorantim Metais Niquel S.A. and export operations to Norilsk Nickel commenced in January 2011.

Full year production was above recent guidance at 10,375 tonnes of nickel in concentrate, 3,239 tonnes of copper in concentrate and 179 tonnes of cobalt in concentrate. 


No exploration activity was conducted during the quarter.
