This colliery (with its wharf at Briton Ferry near Neath) was sold in 1847, but by that time Davis had taken a lease of valuable steam-coal seams on the Blaengwawr estate at Aberaman.
He sank a pit therein 1843, and transported the coal to Cardiff on the Glamorganshire Canal until the Taff Vale Railway was opened in 1847.
[2] When Davis moved the main focus of his business operation from Hirwaun to Blaengwawr he encouraged a number of his workmen to follow him, and he established the Wesleyan Chapel at Aberdare, which was largely frequented by his employees.
[3] In later life, Davis turned his attention to the Rhondda Fach valley, which at that time was almost entirely rural and uninhabited.
[1] This enterprise prospered and was converted into a limited liability company, with a prospectus published inviting the public to subscribe for debentures and shares in May 1890.
