I know C1 costs are not total costs. Your original question was whether the EBITDA of 50M was achievable so I dont know why you are now referring to total costs.

As to concentrate charges found this on the web

"ZINC CASH COST (C1)
The method used to analyze cost variations is the “Zinc Cash Cost (C1)” calculation developed by Brook Hunt, a British consultancy company.

This methodology calculates the cost equivalent of producting one tonne of fine zinc and includes the following costs: Mine development, stripping, mining, treatment, camp administration, concentrate transport. Also, included are the smelter terms for zinc concentrate sales; i.e. treatment charges, penalties, and the approximate reduction of 15% of the fine tonnes produced. No administrative and financing costs are included.

On the credit side, by-products are subtracted from costs, comprising: payments for lead, copper, silver in concentrates, and for silver in oxides and smelter fluxes.



Also in the April 2007 quarterly one of the major reasons for the reduction in c1 costs was the new concentrate sales agreement

So is $2 still dreaming
