Shares in SolGold carved out gains of 26 per cent on positive news from the analysis of drilling at its exploration project in northern Ecuador.The AIM-listed company which has exploration operations in Ecuador, the Solomon Islands and Australia, said the assay results of the first drill hole at the Alpala prospect within the Cascabel project confirmed the visually encouraging mineralisation encountered and reported by the company last month.The assay results indicated there was copper-gold mineralisation over two areas of the drill hole as well as some high grade zones of more than 1% copper which will have to be retested using a less sensitive technique.The assay results from a second hole are awaited while a third hole is being drilled and was at a depth of 183m as of yesterday, the Brisbane-based company said.Shares in SolGold were up 26% at 8.5p at 16:22 on Thursday.TB
