The bulk sampling facility will be built by Consulmet in South Africa in modular units for container shipment and will use x-ray sorting technology to protect large diamonds, technology that Star intends to use in its final plant at the site.

The company did not say when the plant would be installed on site. Rio Tinto Exploration Canada has an option to acquire up to 60% of the planned mine.
