That portion of the Star resource that falls wholly within the FALC joint venture property is summarized in the following table.

Mineral resources are accumulated within an optimized floating-cone pit shell.
Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be
materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing or other relevant issues. (3) The quantity and grade of reported inferred resources in this estimate are conceptual in nature. There is no guarantee that all or any part of the mineral resource will be converted into a mineral reserve.

A conceptual floating-cone pit shell, based on the economic parameters in the table below, was used to estimate a Mineral Resource on the Star Kimberlite. This meets the CIM requirement for “reasonable prospects for economic extraction”. Economic parameters were derived by P&E from knowledge of similar projects. The overall pit slope angle of 25° was based on preliminary geotechnical investigations, which suggest that a standard bench configuration with a slope of 18° in the overburden and 30° in ore and waste rock is achievable. Estimated grades are based on the recovery of diamonds from bulk sample pilot plant processing of Star kimberlite, and therefore diamond recovery was assumed to be 100%.

Overall Pit Slope Angle
As a test of the sensitivity of the Star resource to market and diamond price fluctuations, the resource model was also run with the High value scenario pit shell using the WWW Low and Model price scenarios. The results suggest that the Star resource is relatively insensitive to moderate diamond price fluctuations, as shown in the table below.
