Frongoch

30th May 2009

Recently my self and Christine made a mad collecting trip to Frongoch mine in mid-Wales, we were getting cheesed off with the daily routine of work. So we started off at 4.30am last Saturday having decided the pervious night to go. After the 3-4 hour car trip we arrived at Frongoch, with a stop off at Newtown for breakfast.
As it turned out it was to prove some of the best micro collecting we had done for over 10 years from the dumps of this mine. My collecting having started at Frongoch over 20 years ago. After a morning looking at likely areas of the dumps, with some luck. We stopped for a bite to eat and a cup of coffee. After which we continued our search, one particular area looked promising as a layer of small to large boulders of vein stuff was making an appearance bellow a layer of dressing fines. Although the fines were a pig to dig through we managed to make good head way after about an hour. It was then we started to pull out lumps of vein stuff showing good alteration.
A few hours later and two bag full’s later we retuned to the car well satisfied with the days colleting. Loading up the collected material which I thought was going to produce some good examples of classic Frongoch minerals; we started on the long journey home. Having not gone more than 10 miles when I could smell a strong odder of diesel. So we stopped just out side the village of Llangurig, and called the RAC, two hours later we found out we had a punched fuel hose spraying diesel over the engine. Half an hour later we had a tempary hose fitted, and were on our way again; arriving home at eleven thirty at night. Too tied to unload the car we left it until the next morning.
Not being able to leave the minerals any longer I unloaded the two bags, and unwrapped them, we were surprised to find that a lot of the collected material was relatively rich in Schulenbergite, and possible brianyoungite with bechererite (schulenbergite must be considered very rare from this mine). Corroded masses of galena were rich in micro crystals of anglesite some with susannite, only found one specimen of IMA2008-21. Also came across some nice examples of caledonite overgrown on Schulenbergite, and two extremely rare specimens of lautenthalite from this mine. All in all a very satisfying collecting trip even with the problem on the way home. Still got many hours of trimming and labelling to do.

Yes we went back to Frongoch again, and had another go at the area below the dressing fines again with limited luck, but we did find some good lumps of altered veinstuff. Plus we looked at some othere areas again with some fair finds. Lots of hard graft digging useually comes up with some thing.

A number of things we found on the previous trip we could not identifiey, and will have to submit them to xrd etc. We will keep the Blog posted on any results.
