Question

A month or so ago I asked a director from Focus the following question:

What do you see the cash costs coming down to at Coolgardie and Laverton?

The response was "Coolgardie probably will not go any lower than $900 and Laverton $1000"

Someone on HC had suggested a few weeks back that the open pits at Apollo would reduce the cash costs at Laverton considerably.

So, now I am a little confused.

If someone with more knowledge than myself (probably most of you) could explain realistically,
1. How the company could reduce cash costs at Coolgardie and Laverton.
2. By how much could the costs be reduced?

Thanks in advance.
