• "T <br /> LANGsTON <br /> CONCRETE INC. <br /> Exhibit L: Reclamation Costs <br /> The wash plant we are looking at moving into the property is an electrically driven Cedar Rapids <br /> plant with a screen and sand screw. It is a mobile plant mounted on a FabTec chassis and will be <br /> set up in a portable fashion. (Meaning that it could be dismounted from the cribbing it will sit on <br /> and pulled away with a semi tractor.) We poured concrete slabs to set the wash plant on as well <br /> as the controller van. We also built a ramp with concrete walls to feed the surge bin. A few <br /> portable conveyors/stackers will be set in place off the plant to pull material from the processing <br /> plant and into a stockpile. <br /> We plan on leaving the concrete structures in place for post mining land use. We feel we will be <br /> able to make use of the concrete pads as well as the ramp we created with the concrete walls for <br /> a customer load out of marketable materials. <br /> The pond we plan on installing will be just to the North of the plant and mostly East. It will run <br /> in a long skinny West to East orientation. It will be approximately 25' wide, 500' long and 10' <br /> deep. To calculate the cost of a reclamation operation, we referred to data provided to us from <br /> 2016 in our Technical Revision#1. In 2016, the operating cost of a D-8 dozer was $169.91/hr. <br /> We do not know what the current operating costs is today, but used a 10% inflation increase and <br /> came up with $186.90/hr. The average push distance is approximately 50'. And the material <br /> consistency is the same as well as the unit weight. Therefore- 16hrs. x $186.90 = $2,990.40 to <br /> complete the operation. A mobilization fee can be assessed at $1,000.00. For a total of$3,990.40 <br /> as a reclamation cost. <br /> We are going to be taking water from the Minnequa canal. The water in the canal is owned by <br /> Evraz Inc. The water line will need to be decommissioned for post mining land use. We intend to <br /> "abandon the line in place." To do this, an excavator and some concrete will be needed. We <br /> believe it should take an excavator approximately one hour to dig up one end. And about a half <br /> an hour to backfill it. For a total of three hours. We do not have an estimated cost per hour to <br /> operate an excavator, but we try to get $220.00/hour for our excavators on projects we bid. <br /> $220.00 x 3 hours = $660.00. An estimated 1/2cy of concrete should be all that is needed for <br /> each end to cap. For a total of lcy of concrete to cap the ends. We currently sell 3500psi concrete <br /> for$190.00/cy. A mobilization fee of$1,000.00 can be assessed as well. For a total of$1,850.00. <br /> ($660.00 + $190.00 + $1,000.00) <br /> We are going to ask the division for a cost of the reclamation of the additional 5 acres of land <br /> that we are asking to be added to the existing permitted area. We are unfamiliar with the <br /> calculations necessary to asses a dollar value to this. Simply put, we do not know how the <br /> Division assigns a reclamation fee by the acre to add to the amount needed for bond. We are <br /> comfortable with whatever the Division determines. And will acquire a bond to adequately cover <br /> the total of this as well as the items added above. <br /> 902 South Union Street Florence, Co. 81226 (719) 784-3878 Office (719) 784-1158 Fax <br />
