At 6 g/t, and 50 tpd, the mill produces ~300 oz/month. With mill costs ~$150k/month, the mill operations should be profitable with gold above ~$500/oz. This is simplistic, ignoring extraction efficiency, royalties, etc., but it's obvious the mill itself will be profitable since gold is not going anywhere near that low. And the mill expansion is nearly complete, which will double or triple production (presumably w/o doubling or tripling costs). At that point, revenues should easily offset most of the cost of getting to the point of mining new ore and greatly reduce the amount of financing needed.
