If you do the figures on MZI even at a discount price for zircon you will be surprised at the figures.Just get the tonnes and multiply by a zircon rate and you will see.They may look at the strick price of 2.5c on the options MZIO to get more money in the door for the Keysbrook project.
Also if you look at the price of zircon it has moved up over the last 5 years higher by percentage than gold.
