Comment/Objection Narrative* <br /> I am writing to oppose Grand Island DMO application providing the following concerns-in my opinion: <br /> X-Given that the current operator is not properly certified,as far as I could discover in public records(see <br /> attached July 5 and Nov 29,2025 correspondences from CDPHE)and the copper exceedances in at least one <br /> of the wells,and that the treatment system was designed for inactive mining;this application does not <br /> demonstrate that the current treatment and monitoring systems in place/proposed will adequately protect <br /> ground and surface water during active mining. <br /> X-The application does not mention the risk of wildfire ignition(from the explosives used and stored on site,or <br /> sparks from equipment),despite the mine being located in the highest risk level in the state for wildfire <br /> probability,severity,and post fire impacts(maps from DNR,CSFS).The application does not provide sufficient <br /> information to ensure protection of property and environment from a wildfire,flood,or other disaster. <br /> X-The application does not provide any details on the proposed mill, processing,chemical use and storage,or <br /> maps of underground operations to allow DRMS and others to understand whether it can successfully operate <br /> as a DMO,while still protecting the environment,water quality,air quality and the community within and off <br /> property. <br /> X-The application provides insufficient information of transportation and how ore,tailings,and 20-40,000 cubic <br /> yards of waste rock will be transported within the property and off. DRMS purview is on property with impacts, <br /> and given the sheer anticipated amount of ore and waste rock production on site,this would likely lead to undue <br /> harm to roads,the environment,wildlife,air quality,noise pollution,etc.There is not a sufficient transportation <br /> or storage plan included in the DMO application. <br /> X-The application fails to demonstrate how the mine will control water pollution during the mining operation <br /> and in the long-term, post-mining.Given their history of water pollution citations,a detailed analysis of how the <br /> mine is going to ensure future water quality protection is required under state law. <br /> X-The application references a milling operation on site,but fails to provide sufficient information for DMO <br /> review regarding the mill details, impacts and reclamation requirements when operating a milling operation on <br /> site. <br /> X—The application does not discuss impact studies regarding 50 years of trucks moving 70,000 tons of ore per <br /> year on Caribou Road,on State Hwy 119,through the circle in the Town of Nederland and down the road. <br /> Including, but not limited to noise,dust, road wear(who pays to fix the roads);and overall decreased quality of <br /> life for residents and wildlife. <br /> X—Fiscal responsibility concerning accountability for any and all of their actions;along with transparency, <br /> including clear,weekly communications with Town of Nederland residents and government regarding <br /> operations,violations and status is needed. Previous violations were discovered versus reported to residents. <br /> Permitting Action Comment/Objection is Regarding <br /> • New Permit Change to Existing Permit <br /> Permit Number* (?) <br /> Enter a valid permit number <br /> M1977410 <br /> County* <br /> Colorado County where the proposed operation is located <br /> Boulder <br /> Enter one county only <br /> Site Name <br /> Cross Caribou Mines <br /> Perm ittee/Operator Name <br /> Grand Island <br />
