<br /> <br /> <br />SSR Mining Inc. PAGE 3/5 <br />ponds. The geotubes will be positioned at either Pond 0 or Pond 1, allowing drainage water to <br />return to the pond system via gravity flow. <br /> <br />5. Please provide details on how the geotubes will be handled after the capacity is <br />reached. <br /> <br />After the capacity of the geotube is reached, the tube will be disconnected from the system and <br />replaced with a new tube. The tube will remain in place and be allowed to decant into the settling <br />ponds until the sediment is sufficiently dry for transportation. The timeframe it will take the bags <br />to decant will be evaluated as part of the pilot and is anticipated to vary depending on conditions. <br /> <br />Once filled, the geotubes will be lifted using a small truck mounted boom crane, loader, or <br />equivalent equipment and loaded onto a truck for transport. Geotubes will be equipped with lifting <br />loops (or similar mechanisms) designed to support the weight of a fully filled and decanted unit. <br /> <br /> <br />6. Please provide the maximum number of active and filled/decanting Geotubes that will be <br />stored on-site at any one time and provide details on the disposal of the stored Geotubes <br />(loading, transporting, disposal location, disposal fees, etc.). Please also amend the <br />TR152 Reclamation Cost Estimate table to include these costs to dispose of the stored <br />Geotubes. <br /> <br />CC&V would like to use and store as few geotubes as possible as a part of this test work. CC&V <br />estimates that a maximum of two geotubes will be onsite at any given time (one decanting and <br />one in operation). This provides one month for each geotube to fully decant and it is anticipated <br />that one fully decanted geotube will be transported for disposal each month. Ultimately, the <br />frequency at which the geotubes will be accumulated and hauled off will depend on results of the <br />pilot test itself. <br /> <br />The reclamation costs have been updated to include costs for transportation and disposal of one <br />geotube per month for the 12-month pilot test duration (12 total). The amended TR-152 <br />Reclamation Cost Table is included as Attachment 1. <br /> <br />7. Please commit to submitting a comprehensive characterization report (ABA, TCLP, total <br />metals, uranium, etc.) of the accumulated sludge prior to disposal of the first filled <br />geotube to ensure the handling and disposal plan outlined in Item 6 is appropriate. <br /> <br />CC&V will collect samples of the sludge for analysis to properly characterize the waste and <br />ensure proper handling and disposal. CC&V will submit analytical reports of the accumulated <br />sludge via email to DRMS prior to disposal. <br />In addition, CC&V is requesting an extension to the decision date from December 31, 2025, to January <br />16, 2026, in order to allow DRMS adequate time to review the Adequacy Review 1 responses. <br />Should you require further information, please do not hesitate to contact Jorge Ricaurte at 719-701-6837 <br />jorge.ricaurte@ccvmining.com or myself at Antonio.Matarrese@ccvmining.com. <br /> <br /> <br />Sincerely, <br /> <br /> <br /> <br /> <br />Antonio Matarrese <br />Sustainability & External Relations Manager <br />Cripple Creek & Victor Gold Mining Co <br /> <br />Docusign Envelope ID: 2D18F739-39D8-4955-91B8-CEF73FA3A2BC <br />12/22/2025
