Stanhopeburn mine by drone. Co Durham. Abandoned places UK.

Stanhopeburn was originally opened to mine lead(1830 - 1875), later for fluorite. It was closed in 1982. Flight goes toward Stanhope itself and the river Wear. Couldn't find a name for the place I took off/landed but it's right beside Weatherhill quarry.
