Title: MEYA MINING'S 391-CARAT DIAMOND RECOVERY MARKS MEGA CLIPPIR DISCOVERY

Trustco Group Holdings Ltd ("Trustco") has announced the findings of a recent examination of the 391.47-carat diamond recovered by Meya Mining ("Meya") in Sierra Leone. Trustco holds a 19.5% interest in Meya, which operates under a 25-year exclusive diamond mining license in the Kono District.The 391.47-carat diamond was part of a 515-carat rough diamond recovered in the Meya River kimberlite domain on Tuesday, 20 August 2024, in the first of 16 domains targeted by Meya. Along with two smaller fragments weighing 105.43 carats and 18.11 carats, this marks the second significant find from the region, confirming its potential as a source of high-value diamonds.A detailed examination, conducted by Dr. Evan M.

Further analysis showed the diamond is part of the CLIPPIR variety (Cullinan-like, large, inclusion poor, pure, irregular, resorbed), similar to some of the world’s most valuable diamonds.According to the examination report, the diamond contains metallic inclusions, mainly iron-rich metals, which suggest it formed deep in the Earth, between 360 and 750 kilometers below the surface.
