The mill has been inactive since <br />1985. I would like to know what would be required by the MLRD board to permit this <br />facility and what size reclamation bond would have to be posted. <br />A brief overview of the facility for your reference is as follows: <br />1. The 108 acre millsite has been a historic nullsite since 1935. It was operate] <br />between ]935 and 1940 by the Grand Republic Gold Miiung Co. of Wallstreet as a <br />flotation/gravity mill. <br />2. General Chemical Co. -Allied Chemical Co. - (Presently Allied Signal Corl>.) <br />operated the facility between 1940 and 1974 to process 200tpd of florspar ore from the <br />Burlington Mine at Jamestown, Colo. <br />3. Hendricks Milling Co. leased and operated the facility between 1977 and 1'385 <br />to process ore from the Cross Mine and Caribou Silver Mine dump reclamation project. <br />The mill was run sporadically during this period. <br />4. In 1987 the 15 acre tailings pond was covered with 1' of dirt and natural seeding <br />took place with local vegetation and tree cover. <br />5. The county has the property zoned existing general industrial EGI. Part of the west <br />end of the property is a natural landmark -the Valmont Butte -Boulder County <br />Comprehensive plan. Historic use is still granted. <br />6. The millsite was chosen because of its unique geologic setting. The propery is <br />bounded on the north by an impervious Basalt Dike that runs east/west. South of the dike <br />is Pierre Shale which is believed to reach depths of + 3000'. Historic milling operations <br />have placed their sand on top of the shale and evaporated their water. No running; water <br />exists on the property as its elevated well above the valley floor. This makes for «perfect <br />tailings pond area that can easily be reclaimed. Throughout the history of the millsite onl y <br />15 acres of the 108 acres has been used for tailings deposition. <br />7. The mill will require 3 months of mechanical repairs at a cost of $150,000.00 to be <br />again operational. <br />8. Hendricks Mining Co. would keep it as a captive mill for our Cross Gold Prfine <br />Operation and Caribou district mines. We would not nor would we ever consider custom <br />milling. <br />0 <br />Mailing Address: Post Office Box 653-Caribou • Nederland.
