Usually if I have a specific question about the detail of operations I refer to an annual report. It's a really comprehensive document that an ASX company has to release every year. You can use Google to search for this, go to the companies website or the ASX. Very handy indeed.

If you are incapable of reading more than 5 pages of text, can I recommend the "control f" function which allows you to search for specific terms, like "mining services". By following the above steps you will eventually land on page 79, which details your exact question.

You will note the breakdown of services and how the profit is accounted for across internal and external operations.

Having said all of that I'd be very doubtful that you could interpret this information based on your post. Nevertheless good luck, I think you will find your assertions are way off base.
