Harry Winston Diamond Corporation reports Diavik Diamond Mine Third Quarter 2012 Update

Tuesday, October 16, 2012

Harry Winston Diamond Corporation reports Diavik Diamond Mine Third Quarter 2012 Update06:38 EDT Tuesday, October 16, 2012 TORONTO, Oct. 16, 2012 /PRNewswire/ - Harry Winston Diamond Corporation (TSX:HW, NYSE:HWD) (the "Company") reports that in the third calendar quarter of 2012, the Diavik Diamond Mine produced 1.93 million carats from 0.52 million tonnes of ore processed, as compared to 1.93 million carats from 0.64 million tonnes of ore processed in the comparable quarter of the prior year. The 19% decline in ore processed in the quarter was due to a shift in production from the lower grade, lower value A-418 open pit to higher grade and higher value ore from the underground mining of the A-154 pipes. Open pit mining of the A-418 kimberlite pipe concluded in September, although processing of open pit ore from the A-418 kimberlite pipe will continue into the fourth calendar quarter of 2012. For the nine months ended September 30, 2012, the Diavik Diamond Mine produced 5.33 million carats from 1.59 million tonnes of ore processed compared to production of 5.08 million carats from 1.67 million tonnes of ore processed in the comparable period of the prior year. Production for the nine months ended September 30, 2012, consisted of 3.47 million carats produced from 1.01 million tonnes of ore from the A-418 kimberlite pipe, 1.09 million carats produced from 0.25 million tonnes of ore from the A-154 South kimberlite pipe, and 0.66 million carats produced from 0.33 million tonnes of ore from the A-154 North kimberlite pipe. Also included in production for the nine months ended September 30, 2012, was an estimated 0.10 million carats from reprocessed plant rejects ("RPR"). These RPR are not included in the Company's reserves and resource statement and are therefore incremental to production. Diavik's full-year target production is expected to be approximately 7.4 million carats from the mining of 2.0 million tonnes of ore and the processing of 2.2 million tonnes of ore. The decrease in carats from the original plan is primarily due to deferring the processing and recovery of lower value carats from the RPR in favour of processing underground ore containing higher valued carats. Open pit mining of approximately 1.0 million tonnes of ore was exclusively from the A-418 kimberlite pipe. Underground mining of approximately 1.0 million tonnes of ore is expected to be sourced principally from the A-154 South and A-154 North kimberlite pipes, with some production from A-418. Included in the estimated production for calendar 2012 is approximately 0.3 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. The expected run-of-mine ore production for the calendar year is generally consistent with the 2012 plan although some RPR production originally planned for calendar 2012 has been deferred to calendar 2013, when the process plant is expected to have spare capacity. The rough diamond market has stabilized through the third calendar quarter as demand has improved. The Company expects higher than normal rough diamond inventory at October 31, 2012, although a large portion of the inventory carried at July 31, 2012, has been sold. Based on prices from the Company's rough diamond sales during the fiscal quarter, and the current diamond recovery profile of the Diavik processing plant, the Company has modeled the current approximate rough diamond price per carat for each of the Diavik ore types in the table that follows: Ore Type October 2012 Average Price per Carat (in US dollars) A-154 South $135 A-154 North $170 A-418 $95 RPR $45 Forward-Looking Information Information included herein that is not current or historical factual information, including information about mining activities at the Diavik Diamond Mine and estimated production from the Diavik Diamond Mine, may constitute forward-looking information or statements within the meaning of applicable securities laws.
