In March 2013, Odyssey disclosed an ownership interest in Oceanica Resources, S. de R.L., and Exploraciones Oceanicas, S. de R.L. de C.V. (“ExO”), a subsidiary of Oceanica. ExO conducts mineral exploration and controls exclusive permits in an area in Mexican waters that contains a large amount of phosphate mineralized material. According to its latest financial report, Odyssey Marine Exploration controls ExO through the company's majority ownership stake in Oceanica. Odyssey performed all of the exploration to find and validate the mineralized phosphate deposit and is managing the environmental studies, including an NI 43-101 report in 2014, and environmental permit application process with ExO. The current resource assessment defines the deposit as containing 588.3 million tonnes of phosphate ore with an average "in situ" P2O5 of 18.1%, overburden of 1.14 meters and ore thickness of 2.80 meters. This makes it one of the largest phosphate deposits to be discovered in the world.
