Project overview<\/h2>\n\n\n\n

The port of Maribaya, an important base for Guinea's Simandou Iron Ore Mine, is located on the east bank of the upper Maribaya River in Forecariah Prefecture, Conakry. It borders the southeastern Atlantic Ocean, is approximately 25 nautical miles from Conakry, and has a tropical rainforest climate (24-32\u00b0C average annual temperature).<\/p>\n\n\n\n

Phase I: Iron ore shipping via barge + offshore lighting, throughput of 70M tonnes. 4 berths (12k ton class) and gangways to be built.<\/p>\n\n\n\n

Phase II: Planter deep-water port for 325,000-ton dumpers with a throughput of 80M-100M tpy.<\/p>\n\n\n\n
