    The AGM was held and next years meetings agreed upon.

  • Sunday 19th September - A visit to the manganese mine of Seler Ddu on the slopes of Bwlch Mawr, a mountain with its summit at NGR SH 426 478.  Met at 10:30 a.m. at a very small lay-by\passing place close to a very prominent radio mast at NGR SH 437 478.  (View OS Map)

  • The mine is located on the south east side of the mountain, at NGR SH 431 471.  (View OS Map)  The Seler Ddu mine is fairly small but very interesting underground, being, I feel, quite unique in the means adopted for the support of the worked areas.  At several places, large stones of a different nature to the country rock have being carried in from the mountainside and used to construct support pillars.  The whole working appears to have been excavated using picks only, as no shot-holes are to be seen.
