Woulfe Mining Corp WFEMF

Operating costs are 148$ / MTU!

[Majormac79]

61.84 dollars per ton operating cost

1ton = 1000 kgs

Average grade used in the FS is 0.42%

 

A MTU=10kg

for to get 10kgs of wo3(tungsten) 

1000kgs(1ton) times 0.0042= 4.2kgs

Therefore to get 10 kgs divide 10 by 4.2= 2.38 tons of rock to get 10 kgs equalling 1MTU

Operating cost of 61.84$ times 2.38 tons = 148$per Mtu produced

Majormac, I wish it was so simple. You don't know if they had mining dilution in reserves (I doubt). IMC share of APT refining costs are unknown. You didn't factor 85% recovery in. 

[Majormac79]

You're right i missed the 85% recovery part but i am doing this on the fly( on phone) @ work so bound to miss a parameter or two

Same here, I just made error myself with forgetting cost escalation factor.

I get $186/MTU Note: 1 MTU = 1 tonne APT Spent 10 minutes crunching some numbers and comparing to Glanville Valuation report. Here are my findings on OPEX/Tonne APT produced:   Feasibility: 1,200,000 TPA Ore 400,000 TPA MTU Produced 3 tonnes ore/MTU Opex of $62/tonne ore = $186/MTU Not bad.   Glanville Report Note: Also based on 1,200,000 TPA Ore, assume 400,000 TPA MTU produced.

I think my way is the simplest although I apologize for my 1 MTU = 1 tonne WO3 fact when in fact it is 1 MTU = 10 kg WO3 whether in concentrate or APT form. At a high level, Woulfe mines 1.2M TPA and gets .4M TPA APT for a multiplication factor of 3X on the OPEX figures/tonne ore.  What we don't know is how many tonnes if waste rock there are and if this increases the

I think everyone are in the ballpark. Except for 55% of APT plant opex. The company doesn't need to disclose it, but it means they aren't getting the full spot price per MTU. When this is factored in along with APT plant losses, the costs would be closer to 200/MTU co-product basis. The fact is both capex and opex went up substantially. I don't know whether this affects financing, but

[mercurysmith]

Junior_minor, you calculate that both Capex (capital expenditures) and Opex (daily operating expenses) went up substantially.  I am not sure I understand your logic in that regard. Regarding Capex, on the company website with the April 2012 presentation, they again confirmed their "Sangong Project Financing" capital costs of 150M.  The FS came in with Capex of 151.3M, so I don&

mercury, I was referring capex from scoping study. I agree, there wasn't really surprise compared to more recent numbers.  Operating costs on the other hand, went up big time per tonne basis. MTU basis they stay about the same as in scoping study because the grade is better. I had estimated, opex increases about 20% from scoping study, but it was more. Difference between cash cost
