The D-Tree exploration tenements are located approximately 10 kilometres west of Paradise South. Historical estimates from the 1960s identified 220 million tonnes at the D-Tree project with further exploration conducted by Legend International. The drilling completed supported an Inferred Resource of 135 million tonnes at an average of 13.8% phosphate with only 35% of the area covered by the historic drilling covered.

There is exploration potential for the D-Tree project with potential for future resource increases. The project has the potential to produce phosphate concentrate, providing additional feedstock for the processing plant located at Paradise South or be used as a future stand-alone project subject to future exploration success, further studies and funding.
