Mulberry Downs Quarry is a disused opencast tin mine in Cornwall, England, UK.
[10] In 1834 the Bodmin and Wadebridge Railway opened, with a branch line to Ruthernbridge provided to convey the output of the nearby mines, including Mulberry Mine, out to Wadebridge for transfer to sailing vessels for onward transport.
[11] The 3.2-hectare (7.9-acre) disused mine, located within the civil parish of Lanivet, was originally notified as an SSSI in 1973.
[12][13] A second notification in 1985 increased the area slightly to 3.5-hectare (8.6-acre)[14] The site was most recently surveyed in 2011 when the condition was described as favourable.
