Ms. Jo Ann Tischler, Corporate Director of Compliance and Permitting for Denison Mines, requested this inspection to identify asbestos-containing materials (ACM) that exist in the building. ACM -IHI identified the foliowing materials: • Vinyl floor tile and mastic (7,960 square feet) • Floor tile mastic (1,785 square feet) Conclusions Asbestos -IHI recommends that a Utah-certified asbestos abatement contractor remove and properly dispose of all the ACM in this building that may be disturbed during remodel or demolition activities. Cost Estimates IHl's cost estimates for a Utah-certified asbestos abatement contractor to remove the ACMs outlined above are approximately $35,650. The estimated cost does not include travel expenses for an abatement contractor. These estimates do not include the costs for asbestos abatement design and management consulting services. The report that follows this Executive Summary should be read in its entirety because it includes important information, such as material descriptions and locations, regulatory requirements, and building-specific recommended response actions.

Ms. Jo Ann Tischler, Corporate Director of Compliance and Permitting for Denison Mines, requested this inspection to identify the asbestos-containing materials (ACM) that exist in the building . ACM -IHI identified the foUowh lg ma terials: • Pipe fitting sealant (20 units) Conc lusions Asbestos -IHI recommends that a Utah-certified asbestos abatement contractor remove and properly dispose of all the ACM in this building that may be disturbed during remodel or demolition activities . Co st Estimates lfll;s cost estimates for a Utah-certified asbestos abatement contractor to remove the ACMs outlined above are approximately $100. The estimated cost does not include travel expenses for an abatement contractor. These estimates do not include the costs for asbestos abatement design and management consulting services. The report that follows this Executive Summary should be read in its entirety because it includes important information, such as material descriptions and locations, regulatory requirements, and building-specific recommended response actions .

Our monthly maintenance charge would be $94,750.00 which includes our labor, specialized lube trucks, support vehicles and equipment, specialized tooling, scheduled oil sampling, parts trailers and inventories, mileage and travel expense. NCRL will provide two (2) full-time maintenance technicians on site fifty (50) hours per week on a schedule to be determined, Monday through Friday. Energy would have to schedule the machines available for a time frame yet to be determined adequate for NCRL maintenance personnel to perform the required maintenance. NCRL would invoice Energy for the monthly maintenance charge at the start of each month. Repairs: NCRL would be responsible for all repairs including parts and labor on our machines other than failures caused by damages or mis-use. Repairs include items as minor as starters, alternators, water pumps, hydraulic hoses, etc. to the major items such as engines, transmissions, differentials, brakes, hydraulic pumps and cylinders, etc. If time permits and Energy requests NCRL's technician to perform repairs or maintenance on their machines, our hourly charge would be $140.00 per hour for standard time, $178.00 per hour for overtime and $205.00 per hour for Sundays and holidays plus materials. Mobilization, Freight and Assembly Charges: Mobilization: The mobilization charge of $57,250.00 includes the moving expense of our support personnel, set up the job site, and transportation costs of our vehicles, parts and tooling inventory to the job site. NCRL would charge the same amount to demobilize at the end of the project. Freight and Assembly Charges: The freight and assembly charges listed on Attachment A are based upon all machines shipped by truck to the job site. Energy would be responsible for demobilization including disassembly and return freight on all machines, parts, vehicles and equipment, at the end, or at any time during the rental period to Rapid City, SD. NCRL would be responsible for freight to the job site for all stock order parts shipments, emergency repair parts, maintenance parts, G.E.T. and bulk oil shipments. Once the equipment has been delivered and assembled, an inspection would take place. During the inspection, a representative of NCRL and a representative of Energy will verify on the Acceptance Report the condition of the equipment. Energy's Responsibilities Include: Operators: Provide the operators as needed to operate the machines as stated in Caterpillar's operating guide. NCRL will provide, at no expense to Energy, qualified training instructors for the purposes of training operators. This training would take place on the jobsite at the initial start up of the job and would include classroom, walk around, and in iron demonstrations. Fuel: Supply and fill all fuel for equipment including NCRL's service vehicles. February 4, 2021 Energy Fuels Resources (USA) Inc. Page3 Damages: This includes glass breakage, bent handrails, stepladders, fenders, etc. NCRL's normal policy for repairing damages to rental machines is to repair them when the rental period is completed, however, if the damaged item is of a safety concern, we would repair the damages as soon as possible after they occurred. An item lized list of the parts and labor required would be provided to Energy prior to starting the repair, and invoiced at current list prices plus freight upon completion. Undercarriage and Tires: Energy would be responsible for all tire wear including tire damages on the machines with an asterisk listed on Attachment A. Equipment would have to be returned with same brand and model tires as when delivered, or prorated accordingly by percentage of tire wear and condition at termination of rental period. Upon delivery of machines, a representative ofNCRL/BMC, a representative of Energy and a representative from an independent tire dealer or manufacturer would jointly verify in writing the condition, percentage of wear, and tire value. Upon termination of rental, we would again have the representatives mentioned above determine the condition, percentage of wear, and tire values. Any differences noted, would then be charged or credited to Energy including both materials and labor. Undercarriage wear on all track type machines would be NCRL's expense. Ground Engaging Tools: Energy would be responsible for all parts relating to ground engaging tools (G.E.T.), i.e. cutting edges, ripper tips and protectors, bucket tips and adapters, edges between adapters, wear plates on bottom of buckets and all mounting hardware. NCRL would install these items on an as needed basis at the current Caterpillar list price plus freight at no additional labor costs. All machines would be delivered with new G.E.T. items and are to be returned with new. Rates and conditions would be subject to change at time of commitment.
