Vis=-/8/1996 (nance + nance) a prominent bob wall marks the site of the copper mine of collacombe down. Containing a large brick-arched plug door that is likely to have served as the cylinder opening, the wall is that of a pumping engine house thought to have housed a 40 inch engine. The engine house faces s and probably had a single boiler on the e side, and a separate stack (nance + nance).

Vis=-/3/1998 (ea) there is a disused copper and zinc mine to the w of down farm at collacombe down. This mine is on the n fringes of an extensive mining area in the tamar valley known as the devon great consols, the richest copper mines in europe in the 19c, with workings extended over an area of 160 acres including arsenic production (sx47sw/504) (exeter archaeology).

A series of earthworks of trackways, spoil heaps, ditches and banked features and structures are visible on aerial photographs and interpreted as a post-medieval industrial complex. Map object partly based on this source.

The earthworks and structures transcribed as part of this survey are clearly associated with Devon Mine and likely of modern date. The extent of this mine and its boundary with Wheal Conquer to the west, is not clearly demarcated on historic mapping and so has been polygonised according to an ‘extent of area’ mapped by this survey. Industrial features which may be associated with this mine, but fall outside of this area have consequently been excluded from this record. Only part of the photo reference is given in the transcription attributes, so the date of the photograph is not known.
