After the run in the shares it could be time to lock in your profit at Cambrian Mining (tipped here in March last year at 69.5p and currently 156.5p). Ten days ago, Cambrian sold half its holding in Asia Energy for £27.7 million, which was nearly all profit. That is equivalent to over 30p per Cambrian share. With its big holding in Western Canadian Coal, Cambrian continues to look fairly valued, but the price is now vulnerable to profit-taking (the shares have already come back from 180p) and there will almost certainly be more chances to get back in at lower levels.
