Hi Roy, there was a short straight with a sharp right turn and sharp left to the shaft/winze, I'd even go as far as quessing the shaft was dug before the adit if that makes sence- the bottom of it was filled with farmers waste and water, sounds extremely deep! Over the shaft the level ends.. We are unsure if there is another level at the bottom of the shaft.. I wouldn't call the said mine cwm ricket tho.. Its above the Rhydybenwch picnic site.. There are also adits along the river next to the site, one that is of a fair size but chest deep and turns at the end, u can see false flooring below the water but the level carries on a fair ways, we planned on going past this with wetsuits and a rubber ring etc but haven't got roundto it yet.. Could be anything past there! I put a post up about this set of mines last year and someone replayed about it mite belong to a different mining company to cwm ricket, I'll try and find the post. Something along the lines on nant melin?
