Poldark Mine, Cornwall

Poldark Mine, Cornwall

Originally known as Wheal Roots and later included in the Wendron Consols sett the mine is known today as Poldark Mine. It was a small tin mine located adjacent to the hamlet of Trenear, 600 metres NE of Wendron, in the southwest of the Carnmenellis Granite.

Wheal Roots Lode - 9" to 2' wide Blue Peach containing 0.8% SnO2 with haematite on the hanging wall. Little is known of the early working of the mine, which was originally worked sometime between 1720 and 1780. In 1856 it became part of the Wendron Consols Mine and is shown on the surface plan of that mine as 'old men's workings' meaning that it was at that date considered a very old mine.

The main lode/vein trend is ENE-WSW. The earliest phase of mineralisation is in the form of millimetric schorl veins, which occur as fracture infills and as coatings on joint planes. These veins trend around ENE-WSW (050°-080°, dipping NW) and also (primarily as joint coatings) NW-SE (120°-122°, dipping NE). The more numerous ENE-WSW set form a 'lode zone,' several metres in width, within which the main-stage blue peach lodes were emplaced.

The lodes in the banks of the stream were originally worked by opencast methods before underground mining began. The workings are fairly extensive and include the main adit level, a number of shafts and three stopes (the largest of which extends above and below adit level and is pumped out to allow access. Flooded workings continue below the main stope, to an unknown depth.

1856, following the takeover by Wendron Consols, there is no record of any further work being undertaken at Wheal Roots, apart from the use of the stamps and dressing floors for processing tin ore.

Poldark has been opened now as a tourist attraction. Because Wheal Roots was once a mine, Poldark is therefore required to be a Registered Mine. Had the levels been originally driven for public access then the 'mine' would be designated a tourist attraction and would not be governed by the Mines and Quarries Acts.

You can go down Poldark Mine about 200 feet through very old workings (that is about 60 metres or - in mining terms - 33 fathoms!) and it is well worthwhile to get a real feel of what it was like down a mine, as water cascades away into dark depths below your feet.
