Read the passage below carefully and evaluate the statement that follows:
In 1909, British colonial geologists discovered commercial coal deposits along the Udi Ridge in Enugu, Nigeria. Coal mining officially began at the Iva Valley mine in 1915, transforming Enugu from a quiet agricultural settlement into a major industrial hub. The coal extracted was primarily transported via the Eastern Railway line to the port of Port Harcourt, constructed specifically in 1913 to facilitate maritime exports and supply fuel to steamships. Although coal production peaked in the mid-1950s, powering domestic electricity generation and the railway network, the discovery of crude oil in Oloibiri in 1956 shifted the country's energy focus away from solid minerals. Consequently, coal extraction experienced a sharp decline, leading to the closure of several prominent mines by the late 1960s.
Statement: The port of Port Harcourt was constructed after coal mining operations officially began at the Iva Valley mine.
