2. Choices • Open Pit Copper • Block Cave Copper • Quarry

3. Copper Deposits

4. A Closer Look Army Test Range National Wildlife Refuge

5. More About Your Location

6. Sections 7,8, 18, 17 of Township 12 S 14 W of Great Basin Principle Meridian and Baseline

7. Satellite Image

8. Closest “Road” Access

9. Go Up to Old Pony Express Route

10. Old Pony Express Road Dugway Proving Grounds Fish and Wildlife Refuge

11. Your Roads and Population Centers Millard County’s main town Most of Juab County’s 6000

12. The Setting And Challenges • You are on open public BLM lands in a mountain range in the middle of a roadless desert • You are in a county with 6000 people 0 none of whom live anywhere near the mine • You have little water and a National Wildlife refuge with high water priority near by • The land to the north is sealed as a military reservation

13. Choices • Deposit with Oxide, Sulfide, and Mixed ore close enough to the surface to mine open pit • There is a deeper all sulfide deposit • Both are large

14. Copper Report for Friday • Estimate the price for copper and moly • Estimate the cost of processing copper and moly ore • Explain how copper and moly ore is processed • Estimate the cost per ton for surface mining ore and waste • Estimate the cost per ton for underground mining copper ore by various methods • Analyze the available workforce, travel distances and climate in the area • Identify transportation ways, electric sources and lines • Identify water sources

15. The Quarry

16. Closer Up View

17. Your Topography

18. Your Stratigraphy Starts at 420 feet 30 feet GorevilleLimestone 20 feet Ford Station Limestone Very thick Shale sequence Below the Menard 20 ft Shale 10 feet Shale 50 feet Cave Hill Limestone 20 ft Cora Limestone 30 ft Shale 10 feet Shale 20 feet Nagali Dolomite 250 ft Menard Limestone 25 feet Degonia Sandstone

19. Your Market

20. Aggregate Assignment for Friday • Put together a mine concept for how you will mine and what products you will produce • Identify your anticipated production rate • Identify applicable truck, loader and LHD equipment sizes you will try • Quantity of equipment not specified

21. More on Report Concept • This class is supervised work on your own • Start of Week I layout goals for the week • End of the Week (Friday – groups do oral presentations of their results) • Days in between • I present things I believe are needed • I present things that are requested • I let you work • It is possible that I may have a class just for aggregate, or just for underground copper

22. Our Class Products • Weekly reports 25% • Did you do the work required? • Midterm Written Report Check 10% • Final Written Report 35% • Final Oral Report 30% • Grading Scale is Fixed % • 90% A • 80% B • 70% C • 60% D • <60% don’t go there

23. Pick Projects • Each group Pick a Team Leader • Team Leader submits to me the breakdown of who is responsible for what • Grading is a mixture of team and individual work • Your team does effect your grade • It is possible for people on same team to get A’s and C’s (or worse if someone is a total free-loader)

24. Design Packages • None are mandatory • MineSight is main design package • Also have Carlson and Autocad Available • Will likely use excel and various web brousers • You can do all drawings by hand with drafting equipment but I don’t recommend it.

25. Coal Project Land of interest is 5 X 7.5 miles located 25 miles north east of Marion

26. Coal Resources • Coal resources are postulated by extrapolating surrounding areas – no drill hole data is known for the area. • The #6, #5, and #2 coal seams are believed to be minable thickness • Coal is believed to occur at about 400 feet depth • The #6 coal is believed to be high sulfur and high chlorine. • The #5 coal is believed to be moderate sulfur if Dykersburg shale is sufficiently thick. • #2 coal quality can be high enough for metallurgical grade at times but quality varies a lot. • Number 2 coal should be within about 200 feet of #6

27. More • Coal seams are believed to be flat and unfaulted. • There is reason to believe dikes may exist in the area. • There may be water hosting fractures in the area also. • No drilling for oil or gas has been done in the area so there are no wells to be protected.

28. For Friday • Pick an exact location for the deposit • Obtain surface feature and topo maps • Identify roads, railroads and transportation routes • Assume that your mine could supply up to 25% of the coal needs of any scrubbed power plant • Identify power plants you could ship to and the amount of coal you might sell • Identify how you could ship coal to those markets

29. More For Friday • Identify prevailing prices for Illinois Basin steam coal • Identify prevailing prices for metallurgical coal • Identify transportation costs from your mine location to the market. • Show transportation routes and methods • Identify power lines in the area and the size and capacity of the lines (how many KV do they handle?)

30. Plan an Exploration Program • Core Drilling will be about $20 per foot with logging of drill holes. • Short Prox $30 per sample Ash Moisture BTU • Add Sulfur for $15 more • Sulfur Forms $100 • Chlorine for $50 • Met Coal Test Battery $500 • Seismic Survey about $20,000 per square mile • Can get you dikes • Possible fault locations • Magnetometer Survey about $3,000 per square mile – only good for vague map and indications of larger dikes or intrusions. • Your initial budget is $100,000
