PRODUCTION

STATISTICS

AND

SAMPLING

Upon completion of the underground bulk sampling program on the Star Kimberlite, a total of 75,435.68 dry tonnes of kimberlite material was processed through Shore’s batch sampling process plant from both Shore’s 100 percent owned Star Kimberlite and the FALC-JV Star West bulk sampling programs. Tonnages include sampling of underground bulk sample material, underground RE samples, geotechnical test samples and clean-up samples.

The following process and recovery plant production statistics were recorded daily and summarized on a per batch sample basis. They are:

  • tonnes of kimberlite processed (wet tonnes) on a per batch basis;

  • DMS concentrate weight (in kgs);

  • +1 to -3 mm, +3 to -6 mm and +6 to -20 mm sized fraction material for Sortex processing (in kgs);

  • +1 to -3 mm, +3 to -6 mm and +6 to -20 mm sized fraction material for grease table processing (in kgs);

  • +1 to -6 mm grease table tailings in secured bulk canvas bags (in kgs);

  • +6 mm grease table tailings for re-crush (in kgs);

  • coarse kimberlite reject material (i.e. degrit and float tailings (in tonnes));

  • slimes volume (in dm3); and

  • moisture content determinations of the kimberlitic material.

From August, 2003 to January, 2007, Howe was involved in the processing, chain of custody and sample integrity of Shore’s underground bulk sample program and LDD mini-bulk sampling program. Since January, 2007, Howe has been providing third party review and audits of the process plant production data for Shore’s ongoing underground and LDD mini-bulk sample treatment programs for Shore’s Star Kimberlite.

P&E believes that the quality of the diamond processing data is reliable and that the sample preparation, analysis and security are carried out in accordance with exploration best practices and industry standards.

DIAMOND PICKING AND SORTING PROCEDURES

Since the commencement of the underground bulk sampling program and LDD mini-bulk sampling program in 2004 and September, 2005 respectively, a total of 2,525 diamond concentrate samples (432 underground Sortex, 433 grease table concentrate, 832 LDD Sortex, 828 LDD grease table concentrate) were shipped in 114 sample submission batches to SGS Lakefield, SGS Saskatoon and/or MSC. SGS Lakefield is accredited to the ISO/IEC 17025 standard by the Standards Council of Canada, while SGS Saskatoon has followed the same quality protocols in preparation for accreditation. MSC is not currently accredited to the ISO/IEC 17025 standard by the Standards Council of Canada as a testing laboratory for specific tests; however, the MSC facility, process and quality assurance procedures have been audited and ratified by an independent industry expert (Harry Ryans, Process Specialist of AMEC; see Ryans, 2006).
