Production and reserves

Workings or exploration A chip sample across a 0.3 m-thick phosphorite contained 22.5 percent P2O5. Samples collected across a 2.3 m-thick section averaged 16.4 percent P2O5, and the entire 11 m-thick phosphatic section averaged 5.7 percent P2O5. Samples also contained up to 733 ppm V.
Indication of production None
