Hi Norb,

I know you were just thinking allowed but no where in even the quarterly that I have read can I find that the team is trying to optimise grade even if at the cost of lower overall tonnage. The quarterly again didnt really mention anything particular about grading or output and rather discussed focusing on optimisation and the continuation of ramp up.

As for the higher grade for carbonate. My understanding either or will work. Either or in terms of higher output with lower grade or lower out put with higher grade ore. For the best outcome we would want more tons and better grade. My understanding is fairly limited but I remember reading somewhere the only issue with lower grade spod is that it essentially takes more of it than it would the higher grade to get the same level of carbonate.
