Overview

Ross Poldark's copper venture in Winston Graham's Poldark novels — an old, derelict family tin mine on the Cornish coast that Ross reopens on his return from the American War of Independence, gambling what remains of his inheritance on finding copper beneath it.

History

Wheal Leisure was historically worked for tin, and was the mine Ross Poldark's father, Joshua, had worked before his death in 1783. By the time Ross returns to Cornwall from fighting in America, the mine has stood derelict for some years. Rather than simply reopening it for tin, Ross and five local businessmen (unnamed in the sources checked for this pass) agree, at the start of Book Two of the novel Ross Poldark, to invest in exploring the ground for copper instead — a considerably bigger gamble, since it means sinking new shafts rather than reworking known ground. The mine formally reopens in April 1787. According to the BBC television adaptation's account of this episode, the early going is hard: two shafts are sunk quickly into ironstone rather than ore, and Ross has to weigh the added cost of gunpowder against his dwindling capital, banking on the miners' rule of thumb that 'where there's ironstone, there's often copper'. The venture also draws miners away from the rival Grambler mine with better wages, straining relations with Ross's cousin Francis, whose family has a stake in Grambler. Wheal Leisure eventually strikes copper and becomes an early success, restoring some of Ross's fortune and giving him the standing to challenge the Warleggan family's grip on local copper smelting — a central conflict of the wider saga.

Workings

Worked through at least two shafts by the time of its reopening celebration; further technical detail on how the mine was worked was not established from the sources checked for this pass.

Closure

Not established from the sources checked for this pass.

What became of it

Not established from the sources checked for this pass; the wider saga continues to follow the Poldark family's mining ventures across later novels, including the family's original mine, Wheal Grace, reopened by Ross and his cousin Francis in the fourth novel, Warleggan.

Canon & adaptations

The BBC television adaptation (2015-19) used a real Cornish site, the ruined engine houses at Owles and Crowns near Botallack, to stand in visually for the fictional Wheal Leisure during filming — a real location representing a fictional one, not a claim that Wheal Leisure itself is based on that site.

Recorded claims

Each claim is marked with its basis — explicit canon, MineArchive inference, adaptation only, or fandom interpretation — and attached to the source(s) below. Where tellings disagree, both are kept.

• Wheal Leisure, historically a tin mine worked by Ross Poldark's father Joshua until his death in 1783, was reopened by Ross and five local businessmen in April 1787 to search for copper rather than tin, at the start of Book Two of Ross Poldark. (MineArchive inference) ¹
• The mine struck ironstone before copper in its first shafts and drew miners away from the rival Grambler mine with better wages, before eventually finding copper and succeeding. (adaptation only) ²
• The BBC's 2015-19 television adaptation used the real ruined engine houses at Owles and Crowns, near Botallack, Cornwall, to represent Wheal Leisure on screen. (adaptation only) ³
