No resource estimate or production timelineLion Rock acknowledged that the Mboma, Loum, and Minta 1 projects are still advancing toward an initial mineral resource estimate. Laboratory analyses are also pending for samples from Mboma, Loum, Minta 1, and North Minta. The project nevertheless has strategic backing from U.S.-based titanium dioxide producer Tronox Holdings, which owns about 5% of Lion Rock.
