High-grade THM returns
Last month the company returned 2-24% total heavy mineral (THM) sands from drilling efforts at its flagship Mannar Heavy Mineral Sands Project in Sri Lanka.
Titanium Sands hopes to achieve early production revenues at the 166 square kilometre Mannar Island Project in northwest Sri Lanka.
Of 357 drill holes analysed, 330 holes or 92% have so far returned 2-24% THM gradings with 35% or 126 holes outside the defined resource.
The company said the drill holes indicated the potential for resource extensions in three separate zones.
