Continental Nickel Reports a Major Increase in Mineral Resources, Including the First Mineral Resource Estimate for the Sleeping Giant Nickel-Copper Sulphide Deposit in Tanzania

TORONTO, ONTARIO--(Marketwire - March 2, 2011) - Continental Nickel Limited (TSX VENTURE:CNI) is pleased to report that Measured and Indicated Mineral Resources at Ntaka Hill, using a US$17/tonne Net Smelter Return ("NSR") cut-off, have increased to 4,981,000 tonnes grading 1.22% nickel and 0.24% copper, with additional Inferred Mineral Resources totalling 1,860,000 tonnes grading 0.68% nickel and 0.15% copper. At the new Sleeping Giant discovery, Inferred Mineral Resources calculated at a US$17/tonne NSR cut-off total 15,400,000 tonnes grading 0.77% nickel and 0.17% copper. At a US$80/tonne NSR cut-off, Measured and Indicated Mineral Resources total 3,683,000 tonnes grading 1.52% nickel and 0.28% copper and Inferred Mineral Resources, dominated by the Sleeping Giant deposit, total 10,900,000 tonnes grading 0.98% nickel and 0.22% copper.

The NI 43-101 Mineral Resource estimate was completed by Roscoe Postle Associates Inc. ("RPA") of Toronto, Ontario and incorporates additional drilling completed, after the 2009 Mineral Resource estimate (Press Release July 15, 2009), on seven separate sulphide deposits, including the new Sleeping Giant deposit discovered in 2010. The estimate is based on data obtained from 230 diamond drill holes totalling 35,361 metres completed to explore for and delineate the various sulphide zones at nominal 25 to 100 metre drill section spacing. 


  • Measured and Indicated Mineral Resources (US$17/tonne NSR cut-off) at Ntaka Hill have increased by 61% by tonnage since the last estimate and now contain 60,900 tonnes of Nickel.
  • Inferred Mineral Resources (US$17tonne NSR cut-off), dominated by the newly discovered Sleeping Giant deposit, total 17.26 million tonnes with 131,000 tonnes of contained nickel.
  • Mineral characterization work (press release February 9, 2011) has confirmed high recoveries of nickel are also possible from mineralization at the Sleeping Giant deposit using conventional mineral processing.
  • The Sleeping Giant deposit remains open in all directions and additional "step out" drilling to expand the deposit is a priority in 2011.
  • A scoping study to assess the economic viability of potential production options is also planned for 2011.

Craig MacDougall, President & CEO of Continental Nickel Limited, commented "this is an outstanding achievement by the exploration team which has not only significantly upgraded the Mineral Resources at Ntaka Hill, but has also advanced the new Sleeping Giant deposit from discovery to an inferred Mineral Resource in just 6 months. This new discovery, which has demonstrated drill intersections of significant grade over width, including locally high grade intercepts, as well as potentially high nickel recoveries, remains open in all directions and has the potential to develop into a major new nickel sulphide deposit. These results continue to justify our ongoing commitment to exploration. Further "step out" drilling to define the extent of the Sleeping Giant deposit will be a primary objective in 2011, along with the commencement of a scoping study. The project's location, within 200kms of a deep water port in a mining friendly jurisdiction such as Tanzania, is an important positive factor in future economic and feasibility studies."

Mineral Resources were calculated from a geostatistical block model using GEMS software and reported at various NSR cut-off values per tonne, constrained by preliminary pit shells constructed by Whittle software. Only resources falling within the pit shells are reported as Mineral Resources. A minimum NSR cut-off of US$17/tonne was utilized to design the preliminary pit shells. Mineral Resources calculated at US$17/tonne, S$40/tonne and US$80/tonne NSR cut-offs are provided in Table I below.

Notes on Mineral Resources:

  1. Mineral Resources were prepared in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") definition standards regarding Mineral Resources and Mineral Reserves.
  2. Assays of drill core were completed at ALS Minerals of Vancouver, BC and included a comprehensive Quality Assurance / Quality Control ("QA/QC") program. All aspects of the core sampling, assay procedures and QA/QC program have been reviewed by RPA and were judged to be of industry standard and suitable for use in the estimation of Mineral Resources. RPA also completed a data verification exercise including independent core sampling and assaying with satisfactory results.
  3. Resource models were prepared based on drill section interpretation using a nominal 0.25% nickel grade cut-off. 3D solids were constructed by CNI geologists using GEMS software, then reviewed and revised as necessary by RPA.
  4. The estimation employed statistical analysis and variography of nickel, copper and cobalt values with construction of block models by zone using GEMS software. Block cell size was 2.5 x 5 x 5 metres.
  5. Grade interpolation to assign grade values to cells used Inverse Distance squared ("ID2") methods. Grades were also determined for Pt, Pd and Au but are not reported here as, on a combined basis, they fall below 1.0 gram/tonne.
  6. A total of 3,529 bulk density determinations on core using the immersion method were used for the estimate, with densities assigned where data were not available, based on an analysis of the correlation between specific gravity and sulphur.
  7. Mineral Resources are reported at NSR cut-off values of US$17/t, US$40/t and US$80/t and are based on open pit mining.
  8. NSR values derived from grade were determined using average long-term nickel, copper and cobalt prices of US$10.00/lb, US$3.50/lb, and US$20.00/lb, respectively; preliminary metal recoveries estimated at 87% for nickel, 81% for copper and 80% for cobalt, and allowances for transportation of concentrate and standard industry treatment charges for smelting and refining.
  9. No minimum mining width was used.
  10. Resource classification involved a review of geological and grade continuity and was based on drill hole spacing.
  11. Preliminary pits used to constrain the Mineral Resources reported were constructed using Whittle software based on slope walls of 45 degrees, 5 metre bench heights, and production costs of US$2.50/tonne mined, US$12.00/tonne processed and US$5.00/tonne general and administration costs.
  12. Totals may differ due to rounding.
  13. The Company is not aware of any environmental, permitting, legal, title, taxation, socio-political or marketing issues that are material to the statement of the Mineral Resources.
  14. The Mineral Resource Estimate is effective March, 2011.
  15. A copy of the Mineral Resource Estimation report completed by RPA will be posted on SEDAR and the company's web site within 45 days of this release.
