Actually zinc and lead have just push back from 5 year highs in A$, the SOP price has been relatively stable or increasing due to lack of new supply, and being in a controlled market. The MOP price has come under pressure but last time i checked STB is trying to produce SOP, and then expand further into SOP. They do have the ability to produce MOP as well. They used US$586/t SOP for the jorc calculations. Half the SOP production comes from MOP which has an opex of US$400-500/t to produce SOP, so its rather difficult to see the SOP price coming close or under this range, so why would you use $400/t for a resource calculation? Youll find that good projects will always attract funding, may want to check Nevsun and the funds that are on its registor, share price has been pushing over C$B this week again. The location is a negative and STB will always trade at a discount for this, however its just too much for me.
