The main period of production at Levant was 1820-1930 during which the mineral output was 130,000 tons copper; 24,000 tons tin and 4,000 tons of arsenic.

You can find the remains of the working's 2miles north of St Just in Penwith SW370345, In fact the whole areas from Roscommon to Trewellard Bottoms is virtually one vast dressing floor complex, with piles of rubble, ruined furnaces, empty treatment ponds, and blackened calcinators. The stack of the ill-fated man engine survives, but the building itself is nothing but a pile of stone, and the shaft is a rubbish filed depression. The timbered level which connects to this shaft has its portal adjacent to the coastal footpath. the 24" whim, engine "in situ", and 70" pumping engine houses on Skip Shaft are in good condition, but only a fraction part of the stamps engine house survives near attendant stack. There is a wooden headframe over one of Levant's submarine levels on the verge of the cliff near Levant Zawn. Extensive treatment ponds and wooden launders are to be seen at Trewellard Bottoms, where the sea is stained a muddy red with the discharge from both Levant and Geevor. The remains of the compressor house has a distinctive red brick stack attached to it, and the calciners left from arsenic production are amongst the most impressive in Cornwall.

Although mining was recommenced in the 1820's the mine history dates back to Elizabeth I. It had reached a depth of 42 fathoms in 1836 and some 550 people were employed. In 1919, at which time the 350 fathom level was being mined, the man engine, which had been installed in 1857, broke , causing the loss of 31 lives. After this time the bottom levels were abandoned, since ladders provided the only means of egress for the miners. In 1930 the mine was closed down.
