• completion of a 5,630 meter delineation drill program to extend the geologic and resource model to a depth of 300 meters,
• completion of an Environmental Impact Assessment report and corresponding Environmental Management Plan,
• ore dressing studies, together with systematic data collection from processing hard (unweathered) kimberlite to facilitate process plant design and diamond recovery grade modelling,
• site layout and infrastructure review, including water and power options.

Mr. William Lamb, Lucara’s President and CEO, noted, “The completion of the trial mining program at Mothae marks a significant milestone in the project’s development. We have now sold in excess of 20,000 carats of Mothae diamonds, the results of which will form a solid foundation for revenue modeling in our economic evaluation of the project. This information, together with a better constrained geologic and grade model and the processing of unweathered kimberlite which makes up the bulk of the Mothae deposit, provide all of the necessary inputs for a thorough economic assessment.”

Mothae Diamonds holds a mining license for the Mothae kimberlite in Lesotho. Mothae Diamonds is jointly held by Lucara (75%) and the Government of Lesotho (25%). One half of the interest held by the Government of Lesotho is free carried, and one half is paid through the Government of Lesotho’s share of project dividends.
