Trustco Group Holdings recently announced the discovery of a massive 391.45-carat diamond by Meya Mining in Sierra Leone. Trustco holds a 19.5% interest in the mine. 

This significant find was made in the Kono District of Sierra Leone, within an area that spans the Kamara Gbense and Tankoro chiefdoms. Meya holds a 25-year exclusive diamond mining license for the Kono 

District. 

“The diamond, recovered on Tuesday, 20 August 2024, is the second exceptional diamond mined from the Meya River kimberlite domain—the first of 16 kimberlite domains within the company’s licensed area to be targeted. Notably, in November 2017, Meya Mining recovered a 476-carat Type IIa diamond, known as the Meya Prosperity, during its initial bulk sampling program. 

Similar to the Meya Prosperity, which was originally part of a 523.44-carat diamond that fragmented into three pieces (476.98 carats, 27.89 carats, and 18.58 carats), this latest discovery involved a 514.99-carat diamond that also broke into three pieces, yielding stones of 391.53 carats, 105.43 carats, and 18.11 carats,” reads a Trustco statement. 

Quinton Z van Rooyen, Deputy CEO of Trustco, commented on the discovery: “Six of the world’s largest diamonds have been discovered in the area surrounding Meya Mining’s licensed zone.
