DTSB has a 50-year concession on a 268-acre granite dimension stone quarry located 23km from Tanah Merah town, Kelantan (northeast of peninsular Malaysia). This is the largest dimension stone quarry in Malaysia with reserves estimated at 600 million cubic meters or 1.5 billion metric tons. This quarry, which consists of monolithic mother rock, has the capacity to produce bulk supply with consistent tonality.
DTSB's granite named "JELI BLUNERO" is an excellent export-quality grade granite, homogenous and it is reasonably price. The granite has a characteristic of coarse-grained texture with bluish-black tonality.
