cash costs

Looking at investing in FML, just have a question for perhaps the more technical. I have gone through the 2010 December annual report and was just wondering if the current cash costs A$878 per ounce region was taken into account after including the bi-product of silver?

I calculated this out at average 2010 prices @ US$20.16 and the A$78,144 to be around 3876oz AG produced from FML taken into account the 34,335 oz of AU looks to be around 9/1 Gold to Silver mined. So we should be looking at around 15000 oz of AG from production of 130000 oz of AU. Dont burn me on the question its a straight-forward honest question as I am unaware of company policy in coming up with cash costs per oz of gold.

Outside of the question it would be nice to see the production figures on silver in the annual reports and not having to go and calculate these things out for yourself. I am also assuming the silver price here is unhedged as well?

Perhaps a question for the company, I guess I can always give them a call tomorrow.

Thanks in advance.
