I also had confirmation on this verbally from a metallurgist. Think there are only 3 mines with viable antimony grades in OZ one was bought by the Chineese about a year back (from Memory) the Chineese will do/are doing to antimony supply what they did to rare earths as they are the main producers.
I am only holding a small amount less tha 1% of NWR's issued capital just to keep an eye on sp movements, and substatial shareholder notices.
Good luck with GBG gmac55
