A study has found that the phosphate deposit in Eppawala contains 25 million tonnes of phosphate that will suffice in supplying material for the next 100 years.
The Ministry of Environment said this has been confirmed through extensive research carried out by the National Building Research Organisation, based on a Court order.
The Eppawala phosphate deposit covers an area of four-square kilometres.
According to the research report, the stringent use of this phosphate deposit will save the government an estimated Rs.9 billion spent annually in import Triple Super Phosphate fertiliser.
Minister of Environment Mahinda Amaraweera said steps will be taken to submit the research report in Court and later present it to the Cabinet of Ministers and Parliament thereafter.
