UK listed companies include AR., Rheochem (being floated on AIM tomorrow), Mercator Gold, Orevest, BDI Mining (floated on AIM a few months ago) and St. Barbara Mines to name a few. Also a number of other holdings - see the OCE thread set-up.
Not surprised you sold out in OCE - things went fairly pear shaped and I'm not sure the original strategy was very well thought through as investees wanted to raise cash by selling their OCE holdings. A year on though and I had another look - they have been successful with their major holdings. The 40% discount looks quite appealing.
