Indicated Mineral Resource Estimate for the Kelvin Kimberlite

Kelvin_resource_statement.jpg

Notes: 1 – resource estimate represents the body delineated to a depth of roughly 510 meters; 2 – grades are expressed as recoverable diamonds above a 1mm bottom size cut-off. 3 – base average value is derived by applying a base case model (see news release, November 15, 2016) to recoverable diamond models for each geological domain in a mining scenario. Some rounding error may occur in the values reported.

Inferred Mineral Resource Estimate for the Faraday Kimberlites

FaradayResourcesEstInfered.jpg

Mineral Resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.

Target for Further Exploration Estimates within Faraday 1 and Faraday 2

Mm3 = million cubic metres, Mt = million tonnes, cpt = recoverable (+1 mm) carats per tonne, Mct = million carats

The estimate of TFFE is conceptual in nature as there has been insufficient exploration to define a Mineral Resource and it is uncertain if future exploration will result in the estimate being delineated as a Mineral Resource.
