cash burn

Has anyone got any idea of the current cash burn of CCU?

There was an Ord Minnett report at the end of last year which reported CCU's cash burn at A$4m / month.

With that kind of cash burn and at current silver price of A$23.20 / oz, I worked out that CCU would have to produce more than 172,413 oz / month of silver to become cash flow positive.

Has anyone else came to a similar conclusion? With the ball mill now operational, will the cash burn rate will now higher? Any comments would be appreciated.
