The Tisma Deposit
The 2nd largest Producing Minerals Sands Company by Zircon Resources
In November 2020, Tisma’s Inferred Mineral Resources were evaluated 137 Mt (with 3.99% heavy minerals) within an area of 1,500 ha. As per these findings, Tisma’s heavy minerals inferred resources exceed 5.5 Mt, inclusive of 4.5 Mt of zircon inferred resources. With a zircon content of 82%, Tsma’s heavy minerals have a unique assemblage value compared to all our peers.

High assamblage value,
Mandiri uses a standard wet concentration process to separate valuable heavy mineral sands from other components to produce a high-grade heavy mineral concentrate, applying a gravity circuit to separate the Valuable Heavy Mineral Sands from the non-valuable and lighter gangue making up most of the input slurry.
Further exploration potential remains substantial as 46% of the concession area remains to be explored while we can still define additional resources below the water table within the area where existing resources have been defined.
Tisma’s alluvium bed deposits allows for low complexity, open pit mining, a method that can deliver higher cash margins, while minimising environmental impact.
In addition, both the mine and the factory are located alongside the Cahayan river, which further helps to lower logistic costs.
The factory is also located in proximity to Benjamasin port, and the airport in Gunung Mas.
