Read the passage below carefully and evaluate the statement that follows.
In 1909, British geologist Albert Ernest Kitson discovered extensive coal deposits along the Udi Ridge in Enugu, Nigeria. Following this discovery, the colonial government established the first commercial colliery at the Iva Valley site in 1915 to supply fuel for the newly constructed railway network connecting Port Harcourt to the interior. The availability of local coal dramatically reduced reliance on imported fuel, powering steam locomotives and maritime vessels across British West Africa. By 1920, the operational workforce had expanded to over two thousand local miners, transforming Enugu from a rural settlement into a major industrial urban center.
Statement: Commercial coal extraction at the Iva Valley colliery commenced six years after Albert Ernest Kitson identified coal deposits along the Udi Ridge.
