I agree they were very aware that they were processing a new pit M4 this quarter and this would increase AISC (as they have explained in the quarterly). so why was this not included in the forecast of last quarter (jan-mar 18)?? Why was the general public told AISC OF 1100-1200 and a select few told it would be much higher?? Hence the dump at the end of last quarter... and why are some people told the day the quarterly will be released (price sensitive information) and others have no idea??
