About 2.7 tonnes of kimberlite from the Kelvin North Lobe was processed by caustic fusion at the Geoanalytical Laboratories Diamond Services of the Saskatchewan Research Council (SRC).
A sample grade of 2.74 carats per tonne for diamonds of commercial size was returned.
Kennady Diamonds CEO Patrick Evans said: "Based on drilling and sampling completed to date, we estimate that the Kelvin – Faraday kimberlite cluster has the potential to host between 12 and 15 million tonnes at a grade of between 2 and 2.5 carats per tonne."
About one tonne of kimberlite from Faraday 2 is also being processed by caustic fusion at the SRC and Kennady expects the diamond recovery results from the sample in early July.
Kennady said processing of the 436 tonne Kelvin bulk sample via the SRC dense-media separation plant is also underway with the diamond recovery results anticipated before the end of third quarter.
The company intends to discover a resource along the Kelvin – Faraday kimberlite corridor of between a 12 and 15 million tonnes at a grade of between 2 and 2.5 carats per tonne. It also plans to find new kimberlites outside of the corridor.
