You are well on the way to being sucessfull in the stock market. You have the 2 main ingrediants. You can ask the right questions and then you need to be able to figure out which answer is more correct. The majority of the time their is no 100% correct answer because we are dealing with future events which may or may not happen.

Just a liitle more on the significance of the grade. Apart from having a significant effect on cost it also has a significant effect on output so you get a double effect on profit. More tons at a lower cost

For your question 7 you are correct I have no idea of the impact on costs of the open cut ore. I need more information. What is important though is at least i know i dont know and could probably find out if i had too but because this event wont happen until next year I dont see it as relevent.
The company has said it will reduce costs. At this stage that is all i need to know.
