The photo below is concord in 1981.
Wh.Concord and Wh.Briton were both reopened in 1810. Briton having been idle since 1791. Concord is reported to have been at work under steam power in the 1820's. Some prospecting was done in this area in the 1920's but more to do with the lodes west of the concord site, so the area has been in the backs of peoples minds as a possible prospect for over a century.
Work was started on opening the present mine in the second week of June 1980 headed by Nick Warrel (Mining Engineer)and Jack Symons (project manager). Due to the complex geology in this area - Faults and heaves all over the place - a surface drilling programme was ruled out, and the decision made to clear the shaft to have a 'look see'. A pretty bold move I thought at the time. Most of the gamble was based on reports compiled from old documents by the inimitable Jack Trounson. A lode in North Wheal Busy is reported to have been dipping steeply into the Concord sett, and at one time had a reported head grade of 120lbs/ton. The geology has been likened to that of the St.Agnes district around the Polberro and West Kitty area.
The adit was found at 27 Fathoms from surface and the deepest the mine attained in this new project was a little over 60 fathoms from surface.
Apparently 6 lode structures were discovered within a distance of 240 metres South of the main shaft. The best of these, and from where the most of the ore was extracted, was Chynoweth Lode, with removable values over a 1.7 metre width. Values here ranged up to 15% Sn and a lode to the south -undeveloped- consistently sampled 7%. Average grade at the mill was 1.4 to 1.7%. Not bad for 'Knacked Bal'! values in the old stopes were running at 1.5%
I reckon there is still room for a small mine in that area. A south crosscut would intersect the North Busy lode and with six lodes to the west and a few more to the east, I'm not surprised that there maybe renewed interest in the sett.
Another prospect is Droskyn and Wheal Ramoth (Perranporth)
check out the full report in the white paper section on this site. I would buy shares in it. :thumbsup:
