Permit for 36500 MT per year exploitation at Fencemaker , 5% average antimony , coupled with a mill able to produce 12MT at 60% daily basis = between $12 - 14M Gross Revenue per year depending on Metal Market. The costs to generate these revenues are unknow as of today .
Let's say 50K per week for the working force = around $2,5M and you can count some weeks off in the winter time ...
Operating cost of the mill are unknow .
The shipping costs are unknow , but typically , the exporter is responsible to load the goods on board . Once the goods are on the ship , the importer is responsible for them and usually is taking the shipping costs to his factory.
The administrative costs + various leasing agreements : let's say $3M
--------
As you can see , it's all speculation at the moment .
You cannot Google the answer there ... lol
