RAPAPORT... Kennady Diamonds Inc. revealed that diamond recovery results from the Kelvin mini-bulk sample, which was processed by dense media separation at the Geoanalytical Laboratories Diamond Services of the Saskatchewan Research Council (SRC), was better than 2 carats per tonne, as expected. A 25-tonne sample was recovered by drilling from ice in an area where the Kelvin kimberlite outcrops at surface, or where the country rock cover is relatively thin. Prior to processing, the Kelvin sample was divided into four batches based on four distinct kimberlite phases, the explorer stated. These four phases were defined in consultation with SRK Consultants of Vancouver.
Patrick Evans, Kennady Diamonds' CEO, said that the Kelvin total sample grade of 2.16 carats per tonne was in line with the company's guidance and confirmed the potential for Kelvin to host a high-grade diamond resource. "It's apparent, however, that the number of larger diamonds in the sample is lower compared with previous Kelvin samples. A higher frequency of larger diamonds in previous samples resulted in sample grades well above 2 carats per tonne. The sampling and treatment methods used for the mini-bulk sample will be reviewed to understand the reasons for this," he said. "In the meantime, we expect to recover a further 28 tonne mini-bulk sample as part of the current summer/fall Kelvin drill program and this sample will be dispatched to the SRC for processing as soon as possible. We expect the diamond recovery results from this second mini-bulk sample to aid in understanding the diamond size frequency distribution of the Kelvin kimberlite," Evans said.
