The bit I find interesting which no one has mentioned is the 500,000 man hours worked this 1st quarter. They must have more men on the ground than we know about.
Looking at the Teck website no mention of Brazil so maybe they are getting out of the country for whatever reason. No mention of nickel either. Its a bit of a misstery why they don't want to be part of HZM.
Selling at a fixed price of 7.3p would stop the share price falling. Also the MM might not be holding much stock at the lower prices of 7.1p 7.2p so giving the MM a chance to load up. But it does explain why Teck didn't take part in the other placings.
