TORONTO, April 17, 2012 /CNW/ - Harry Winston Diamond Corporation (TSX:HW, NYSE:HWD) (the "Company") reports that in the first calendar quarter of 2012, Diavik produced 1.60 million carats from 0.5 million tonnes of ore processed. Diamonds recovered in the 2012 first quarter was higher by approximately 19% compared to the same quarter of the prior year due to improved grades. In the first quarter of 2011, a higher proportion of mud-rich A-418 type B ore was processed which reduced the overall grade. Ore production for the first calendar quarter consisted of 0.1 million carats produced from 0.04 million tonnes of ore from the A-154 South kimberlite pipe, 0.2 million carats produced from 0.10 million tonnes of ore from the A-154 North kimberlite pipe and 1.2 million carats produced from 0.39 million tonnes of ore from the A-418 kimberlite pipe. Also included in production for the calendar quarter was an estimated 0.08 million carats from reprocessed plant rejects ("RPR"). Average grade increased to 3.0 carats per tonne in the first calendar quarter from 2.8 carats per tonne in the comparable quarter of the prior year. The increase in average grade was primarily the result of the production of RPR in the current calendar quarter.
A mine plan and budget for calendar 2012 has been approved by Rio Tinto plc, the operator of the Diavik Diamond Mine, and the Company. The plan for calendar 2012 foresees Diavik Diamond Mine production of approximately 8.3 million carats (100% basis) from the mining of 2.0 million tonnes of ore and processing of 2.2 million tonnes of ore. Open pit mining of approximately 1.0 million tonnes is expected to be exclusively from A-418. Underground mining of approximately 1.0 million tonnes is expected to be sourced equally from the A-154 South and A-154 North kimberlite pipes. Included in the estimated production for calendar 2012 is approximately 1.0 million carats from RPR and 0.1 million carats from the implementation of an improved recovery process for small diamonds. These RPR and small diamond recoveries are not included in the Company's reserves and resource statement and are therefore incremental to production.
Based on the Company's sales during the first quarter and the current diamond recovery profile of the Diavik processing plant, the Company has modeled the approximate rough diamond price per carat for each of the Diavik ore types as follows:
|Ore Type|| February and March 2012
Average Price per Carat
(in US dollars)
|A-418 A Type Ore||$145|
|A-418 B Type Ore||$100|
