Big Ore Bank
Big Ore Bank is a bed of iron ore found in eastern Lincoln County . Worked extensively in the first half of the nineteenth century, this bed was described by Denison Olmsted  in 1824 as "extending from the base of Little Mountain on the north, to the foot of King's Mountain on the south." Exploitation of the iron  deposits began in 1789, when Peter Forney obtained grants to a large section of barren hills. Soon, others joined in the operations, including Alexander Brevard , Joseph Graham , and John Davidson . Forges, furnaces, and bloomeries were established along the Big Ore Bank, and by 1810 Lincoln County was home to six iron bloomeries.
By the 1820s the Big Ore Bank led the state in the production of iron. Most of it was utilized locally for such things as cooking implements, tools, hinges, and nails. Bar iron was turned out for use by local blacksmiths. But lack of adequate transportation limited the market for the Big Ore Bank iron. Despite this drawback, the iron works in Lincoln County prospered between 1820 and 1840, generating up to 900 tons of iron per year.
The coming of the railroads  flooded the market in North Carolina with cheaper iron from Pennsylvania, and the operations along the Big Ore Bank declined. They were no longer economically viable and ceased to function following the Civil War .
