Gamble of the week: a zinc-rich miner

Shares in this company may "have risen strongly in the past few weeks", says Investors Chronicle, but the best is yet to come.

At the time the study was done, the zinc price was $1,815 per tonne. It's now more than $2,000 and, with the global supply-demand balance still tight, Macquarie (for one) expects the metal to average $2,589 per tonne in 2006.

This is all good news for Aim. Production is expected to start in mid-2007 after an investment of about $72.5m in plant and machinery, financing for which is said to be "well advanced".
