Nine companies listed on London’s Alternative Investment Market in the first three months of 2012 – an increase of one company compared to the same time last year, but with 30 per cent less money raised. The figure fell from £67m to £46.9m, according to analysis by Deloitte. In the first quarter 25 companies also de-listed, compared to 21 at the same time last year. The mining sector has dominated admissions this year, with four out of five listings coming from the industry, including iron ore, tin, gold, copper and rare earths. The most notable addition was Rare Earths Global Ltd, which raised £10m at the end of last month. Another big listing was Chinese sportswear manufacturer, Naibu Global International, which listed on 5 April, raising £6m at a valuation of £68m.
