CRG Mining LLC <br /> 510 S. Wisconsin St. <br /> Gunnison, CO 81230 <br /> January 8, 2020 <br /> Dustin Czapla <br /> Division of Reclamation, Mining and Safety <br /> 1313 Sherman St., Room 215 <br /> Denver, CO 80203 <br /> Re: Gold Links Mine, Permit M-1987-143, Request for Technical Revision, New Decline Portal <br /> Dear Mr. Czapla, <br /> With the materials enclosed herewith, CRG Mining is requesting a technical revision for the above- <br /> named permitted mine. The requested change involves constructing a new portal approximately 150 <br /> feet north of the existing portal, well within the boundaries of the permit. <br /> The Gold Links Mine has utilized a main portal to access and develop the workings, beginning with the <br /> mine's historic start a century ago, and continues to utilize this portal throughout the decades of <br /> operating under this permit. <br /> We wish to construct a new decline from the permitted pad, driving back to intersect our 2150 vein at a <br /> lower elevation. This will allow us to extract and haul ore more conveniently, as well as help to contain <br /> any deep water we intercept in the mine. <br /> The dimension of the decline drift will accommodate haulage equipment plus ventilation, etc. We <br /> believe that the estimated 11,000 cubic yards of waste rock to be mucked from this drift can easily be <br /> placed adjacent to the new portal location on existing disturbed land; no expansion of disturbed area or <br /> dump will occur. We do not anticipate intercepting any mineralized vein material during the driving of <br /> this decline. Waste rock will be placed in a stable manner, with a perimeter toe berm to control rolling <br /> material and sediment. The footprint of waste rock to be placed measures approximately 80 ft x 180 ft. <br /> Please see the enclosed map showing the mine site features and waste rock location. <br /> As we have treated all our underground openings, this new portal will also have a well-constructed and <br /> durable steel shed-type entry, competent and stable backfill around it, and include lockable steel doors. <br /> This entryway will be secure for the mining period as well as suffice as a permanent structure for the <br /> post-mining reclamation period. This is in conformance with the landowner's wishes for the site. <br /> Since the portal and the waste rock disposal will be on existing disturbed ground within the permit, and <br /> its installation will include durable materials and stable backfilling and grading, with no removal to be <br /> required for reclamation, we do not feel that there will be any reclamation cost associated, and <br /> therefore no increase in the bond. <br /> (Cont.) <br />
