In the late 1830s, another quarry was opened in the 'Forest' estate, by Mr. James Mathias of Cilgerran. It was called 'Quarry Forever', and situated adjacent to Gigfran quarry. About the same time, Gigfran quarry became exhausted and was thus given up. The industry peaked in the late 19th century, its continuance until that time supported by the coming of the railway in 1869.
