Cross-Caribou Mine (M1977-410) Technical Revision No. 6 <br /> 1. Introduction <br /> This Technical Revision (TR) is proposed in response to the Department of Reclamation (DRMS) Mining <br /> and Safety Minerals Program Inspection Report conducted on March 26,2020 in conjunction with Permit <br /> No. M-1977-410. This TR includes a detailed plan of action for addressing the lack of a Spill Prevention, <br /> Control and Countermeasure(SPCC)plan. This plan describes measures that have already been taken and <br /> are further proposed at the site to address spill related concerns and lack of a plan to address them. <br /> As of the time of this TR, Calais Resources Colorado, Inc. on April 23, 2020 has submitted an 'Application <br /> form for Transfer of Mineral Permit and Succession of Operators', to Grand Island Resources, LLC. (GIR) <br /> who is currently the owner of all the mining claims at the Cross Mine with Permit No. M-1977-410. Both <br /> Grand Island Resources, LLC., and Calais Resources Colorado, Inc are subsidiaries of Calais Resources, Inc. <br /> 2. Background <br /> The Cross Mine site is located approximately 3 miles west of Nederland, Colorado adjacent to the <br /> Roosevelt National Forest,at an elevation of 9700 feet above mean sea level (MSL). The general location <br /> is parcels of land in Section 9, Township 1 South, Range 73 West of the 6 Principal Meridian, County of <br /> Boulder,State of Colorado, as shown on Map 1. This is an existing hard rock mining operation owned by <br /> Grand Island Resources Inc. (GIR), although at present, no active mining is being conducted. The entire <br /> permit area is on various properties either owned outright by GIR or granted through various lease <br /> agreements,as shown on Map 2. <br /> The mine permit M-1977-410 was last revised through Amendment No. 1(AM-1),approved in 2012. AM- <br /> 1 increased the permit area from 2 acres to the current 9.35 acres, provided for surface waste rock <br /> disposal resulting from construction of the Cross Mine Decline portal,and construction of a new office/dry <br /> facility and a new sewer line and leach field. Map 3 depicts the permitted disturbances as approved <br /> through AM-1.This proposed TR will not result in an increase in the permitted disturbance. <br /> The mine is currently in exploration and development stage but will ultimately operate throughout the <br /> year, producing ore of various metals to include gold,silver, lead and zinc. Total annual production of ore <br /> and waste rock will not exceed 70,000 tons per year. The approved mining plan is centered on mining, <br /> waste rock storage,and ore storage activities in the Cross Mine area,and on primarily waste rock storage <br /> in the Caribou Mine area. The waste rock at the site consists primarily of quartz monzonite and gneiss <br /> and is not considered to be acid-producing or metals-leaching material. <br /> 1 <br />
