Sample shipments were carried out on a weekly and/or bi-weekly basis. For each sample shipment, the diamond concentrate samples were secured in wooden boxes. The sample submission would be completed and the wooden boxes would be sealed and prepared for off-site shipment by a secure carrier. The samples were then freighted by the secure carrier to SGS Lakefield, SGS Saskatoon and/or MSC (the laboratories).

When a sample submission was expedited, a spreadsheet containing the following sample information was updated:

  • sample submission number;

  • sample batch number;

  • diamond concentrate sample number;

  • security tag numbers;

  • sample type (primary/re-crush Sortex concentrate, primary/re-crush grease concentrate);

  • type and size of sample container;

  • gross weight (wet) in kgs; and

  • analysis type (i.e. diamond sorting).

The information contained in sample submission sheets provided to the laboratories are:

  • sample submission number;

  • diamond concentrate sample number;

  • security tag numbers;

  • sample type (primary/re-crush Sortex concentrate, primary/re-crush grease concentrate);

  • type and size of sample container;

  • gross weight (wet) in kgs;

  • analysis type (i.e. diamond sorting);

  • number of and gross weight (in kgs) of the wooden shipping boxes shipped; and

  • Total gross weight (in kgs) of the sample shipment.

Upon reception, the relevant laboratory verifies that the chain of custody documents (i.e. sample submission sheet) are cross-referenced with the sample shipment received, that both the wooden boxes and sample containers arrive intact and that none of Shore’s security features show signs of tampering.

Once all of the security checks have been completed, the appropriate laboratory carries out the following laboratory test work:

  • processing and sorting of the Sortex concentrate; and

  • processing and sorting of the grease concentrate.

The processing of the Sortex concentrate consists of drying, screening, magnetic separation, manual sorting, diamond weighing and description. Processing of the grease table concentrate consists of melting the grease in kettles, washing of the concentrate followed by drying, screening, magnetic separation, manual sorting, diamond weighing and description.

The diamond summary reports provided to Shore by SGS Lakefield, SGS Saskatoon, and MSC conform to the CIM guidelines for the reporting of diamond exploration results (CIM, 2003) and,
