1822 Fowey Consuls employed 1,680 people making Treffry the largest local employer. It was said that 100 mules and 30 horses were required to transport the ore the four miles to Fowey Harbour.
Joseph Thomas Treffry linked his mine to his new port at Par in the late 1820s by a canal. The tramway was subsequently extended to a second new port at Newquay.

Two men refused to join in the arrangement and they took refuge in the Count House when threatened by the other men. The miners refused to disperse and magistrates, including Austen and Nicholas Kendall were called in and the Riot Act read, seven of the rioters were arrested. The seven arrested miners were tried Launceston in March with "having committed a Riot at Fowey Consols and Lanescot Mines, in the Parish of Tywardreath. The seven were lucky to be discharged.
1831 The perpendicular shaft for the 80" Austen's Engine was sunk in the winter of 1831/32. The ruins of the engine house is one of the few visible remains left of the mines, and is situated at the northern end of the site of the Fowey Consols.

Although Fowey Consols has suffered considerably from dump removal and buildings demolition, the site still includes significant remains and cannot be separated from the Luxulyan Valley and the canal which linked them both to Par.
The original tramway was replaced by the Cornwall Minerals Railway in 1874, enabling the development of china-clay and china-stone works at the foot of the valley, the last of these works operating until the mid 1990's.
