BACKGROUND

The Coal Upgrading – Briquette (CUB ®) will provide a higher heating value by reducing high moisture by using by flash drying and physical stabilization of the dried product by p y p ybriquetting without the use of a binder

Coal Upgrading – Briquette CUB®pg g q

Good strength and handling properties. Good weathering resistanceg No chemical added

E ll t th l ti Excellent thermal properties. No chemical properties change p p g CUB can be applied to most coals

Cost benefits to end user

S i i hi t 30 % Saving in shipment 30 % ; Increases power plant efficiency 5 % ; Reduces operating expenses ; Easier for coal handling ; Easier for coal handling ; No fine particles

Less CO2 emission Less CO2 emission ; No coal dust during delivery and in the

t k ilstockpile.

COST ESTIMATES

Capital cost estimate based on a conceptual design the capital cost for a 1 million ton per year CUB Plant would be approximately US$ 68 Millions.

Production cost are including power, variable cost and labor costs the production costcost and labor costs, the production cost would be approximately $ 7 per ton CUB.

Investment ConsiderationsEconomics Investment cost ~ $ 68* Million for 1 Million ton CUB per year

Coal mining production cost $ 15/ton X 1 54 = $ 23 1/ton Coal mining production cost ~ $ 15/ton X 1.54 = $ 23.1/ton CUB operational cost ~ $ 7/ton Royalty ~ $ 1/ton Production cost incl coal $ 31 10 /ton Production cost, incl. coal $ 31.10 /ton CUB pricing ~$ 60/ton @ 5,600 kcal/kg ( arb), CUB gross margin ~ $ 28.90/ton = $ 28.9 Million per year Revenue Tax 28 % = $ 8 00 Million Revenue Tax 28 % $ 8.00 Million CUB net margin ~ $ 20.9 Million per year Cost of money 8 % p.a for 1.5 years = $ 8 Million per year Total investment = $ 76 Million Total investment $ 76 Million Estimated Payback Period in 4 years.
