Exhibit D Page 10 will be accessed by exiting Colorado Highway 392 at a point approximately mid-way along that segment,and more specifically at the Weld County Road 67 exit,then traveling southbound approximately two miles to Weld County Road 68,then eastbound on Weld County Road 68 for a distance of approximately 0.1 mile to the Weld County Road 64 alignment. Mine access requires turning right(southbound)at that location;however this requires entry upon a private access/controlled entry segment of Weld County Road 64. All traffic/vehicles must pass through the guard station at this location,and then continue southbound approximately two miles to the mine entrance proper, which is located at/on the Permit Area's north boundary line(see also Exhibit A-5: Mine Access Route). Upon entering onto the Permit Area,the mine entrance road will extend southeasterly approximately 2,917-ft.,at which point pavement will significantly widen to accommodate plant-related activity/traffic,to include access to the mine offices,employee/visitor parking,and major plant facilities. The southern edge of this expanded area will accommodate the "loadout road",with inbound trucks proceeding easterly through the loadout.A short distance thereafter, loaded trucks will then turn north on the egress route to exit the Permit Area and re-connect with the existing private access road in the S1/4 of Section 35;T06N; R63W in order to return to Weld County Road 64 and Weld County Road 68 and final destination points beyond. Interior to the active mining area(s), CSC will establish a series of three primary haul roads that will remain in place for the full life-of-mine.Initially, an east-west oriented primary haul road(to be designated the"Northwest Haul Road")will serve those mine block areas within Sections 2 and 3,respectively(effectively for Years 1 through early Year 7 mining activity),with its length continuously extending in a manner consistent with the pit advance. When active mining then moves over to the eastern portion of the Permit Area and within Sections 2, 11, and 14 respectively(i.e.,latter portion of Year 7 to early Year 10),a second primary haul road will be developed through the central corridor of the mine area,extending north to south through those Sections(to be designated the"East Haul Road"), similarly extending(in overall length)in a manner coincident with the active mine pit progression. A third primary haul road is anticipated to access areas within Sections 10 and 15 (to be designated the"Southwest Haul Road"),respectively(effectively for the latter portion of Year 10 through Year 20),with its length continuously extending southward in a manner consistent with the pit advance. As planned,haul truck(s)will traverse in-pit areas(over varying distances,dependent on active face location)to access the primary haul road(s)and deliver the material to a ROM stockpile area situated proximal to the feed-bin at the wet processing plant.With pit progression typically advancing further away from the plant area,it is envisioned that the primary haul roads will be developed and extended through the defined mine block area(s).In turn, secondary in-pit haul roads will be developed(to accommodate haulage from the active mining face)to establish access to/from the primary haul road(s),as operational needs dictate. Inasmuch as CSC will employ low-tonnage capacity(46-ton)articulated haul units(equipped with flotation tires), it is anticipated that all haul roads will be situated on and constructed of the natural materials residing within the pit floor.Haul roads will be compacted and maintained, as required,employing initial roller compaction, ongoing blading/grading as warranted,and watered for dust control and compaction enhancement,as necessary. CSC will adhere to operating requirements relative to road maintenance and related activities,as such may be introduced by Weld County or other regulating entity. The in-pit primary haul roads will remain in-place for the duration of life-of-mine in order to provide established access to mined-out areas as they become subject to concurrent reclamation activity(see also Exhibit E: Reclamation Plan). In that regard, CSC anticipates"conversion"of each primary haul road(or segments thereof), when the roadway is no longer needed to support high-usage back-haul associated with concurrent reclamation Colorado Sand Company II, LLC Kersey Mine Construction Material Regular(112)Operation Reclamation Permit Application June 7,2024
