"Is the mill cash flow positive at 125 tpd?"
Seems pretty clear to me.
We have profitable production with an average production of 125 tpd, which is still not at optimal. At the final optimal production stage we will be more than profitable.
Then we get throughput up to 250tpd with very little additional cost, and can start building the bank account.
Very little money has to be spent this year in the ROF, as we have earned our 55%, and can sit and wait for infrastructure announcements, which will immediately do more for us short term than any additional drilling.
Sitting pretty.
Best regards
