The industrial metals and mining sector is going well, with Discovery Metals among the stocks in the blue. The copper specialist has had its seven prospecting licences in Ngamiland, Botswana renewed for a further two years. "All areas of interest, within these prospecting licences, have been retained," it said.Elsewhere in the sector, shares in Ferrexpo are flat, even after the Ukrainian iron ore producer announced it has secured a new debt facility, with leading institutions falling over themselves to lend it money.The technology hardware and equipment sector is under pressure despite strong gains from mobile devices software specialist Crimson Tide, which has posted a maiden profit.Despite lower revenue of £0.73m versus £0.75m in the first half of last year, the company scraped into the black with a profit before tax of £1,000, compared to a loss of £35,000 last year."Our new sales pipeline is stronger than at any other time previously and the only constraint to more rapid growth remains the limited debt and equity finance available to smaller companies," said executive chairman Barrie Whipp.Top performing sectors so far todayIndustrial Metals & Mining 6,517.69 +1.99%Forestry & Paper 5,504.16 +1.29%Life Insurance 4,115.21 +1.19%Mining 22,872.80 +0.98%Chemicals 6,176.20 +0.97%Bottom performing sectors so far todayAlternative Energy 3,501.87 -3.22%Technology Hardware & Equipment 588.12 -1.56%Construction & Materials 3,437.53 -1.27%Health Care Equipment & Services 3,160.56 -1.23%Aerospace and Defence 3,230.22 -1.12%
