As to the programme of events, this was as follows:
  • Saturday 15th June - Prince Edward Gold Mine (View OS Map)

    Leader Harold Morris
    Met at 11:00 at the roadside car park at SH 707 389. (View OS Map)  The walk to the mine is under 4 km on a good track having very little rise and fall, and passes a small slate slab quarry which is at present working.
    This was a visit to the surface remains of Prince Edward Gold Mine.  Underground access at the mine was not allowed by the Crown Agency, (having asked for formal permission), but the surface features were found to be interesting, and are located in the pleasant uplands of Snowdonia.

  • Saturday Evening - Dinner, 19:00 for 19:30, at Porthmadog Golf Club, Morfa Bychan, Porthmadog LL49 9UU  (SH 550 373 - View OS Map)  A copy of the menu can be found here.

  • Sunday 16th June - Tanygrisiau to Wrysgan and Rhosydd slate quarries (surface walk) / Cwmorthin slate quarry (underground).

    Met at 10:30 at the small parking area below Cwmorthin Quarry at SH 684 454 (View OS Map),
    for either :
    a.) Surface walk.  The walking party went up to Llyn Cwmorthin then followed the old tramway to Conglog Quarry. The track climbs steeply onward past Conglog Quarry to Rhosydd Quarry Mill, on the Cwmorthin–Croesor watershed, then via short inclines to the upper quarry workings.  From here a descent over the col to the cavernous workings of Wrysgan Quarry, was made, then a final descent brought them back to the cars.
    There is much to see in the way of industrial historic remains on this route, and it is much recommended if you have not visited the area before.
    b.) Underground trip.  The underground party visited Cwmorthin Quarry, via the lake level adit.
