<br />It should also be noted that a majority of the "affected lands" has been redaimed. <br />It is Holdm's inten! to minimize the disturbance to those areas already redaimed <br />and conduct its operations in an area that will disturb a small portion <br />(approximately 15%) of the reclamation completed by 2006. <br />It is anticlpated that the quarry will mine approximately 60,000 to 100,000 metric <br />tons of raw material to produce the 50K to 90K metric tons of gypsum product for <br />the Portland Plant. Mining during the first few years will require minimal <br />overburden removal as the gypsum has been exposed in three areas as shown <br />on the Mine Plan Map (Exhibit C). Life of Mine strip ratio is estimated at 1:1. <br />It is planned that mining operations will be seasonal and occur four to six months <br />during the year. Haulage from the quany site to the plant site in Florence will <br />occur five days a week throughout the year. <br />A. Description of Mining Methods <br />Mining will be conventional open pit mining utilizing drilling, blasting, loading, and <br />hauling methods. A portable crushing and screening system will be brought on <br />. site where the gypsum will be crushed and skxeened for impurities. Final product <br />will be sfodkpiled and then hauled by a third party service from Coaldale to the <br />Portland Plant located approximately 5 miles east of Florence, Colorado. <br />Development work will be performed via bulldozer, loader and trucks. The <br />majority of development workk will be to expose the gypsum beds by stripping out <br />the approximately 12" of growing medium and stockpiling it in Topsoil <br />DeposiYwnal Areas (See Exhibit C -Mine Plan Map, attached). <br />Once the growing medium has been removed and the area has been leveled, the <br />gypsum deposit will be penetrated with a rotary blast hole drill. Drill holes will be <br />3" to 4" in diameter and 30 feet deep. The material will be fragmented via non- <br />electric blasting systems and blasting agents. tt is estimated that there will <br />approximately four (4) to five (5) blasts each year to yield the total material <br />required for final product. The size of each blast will be approximately 25,000 <br />metric tons. Blasting will cor>fonn with ATF regulations and will be monitored for <br />seismic control. <br />After blasting, materials be loaded and hauled to a mobile crushing system <br />where it will be crushed and screened to a % to 3" product. Crushing and <br />screening will be staged as dose as possible to the mining face as pradipl. <br />Once kxushed "and screened, final product will be hauled to a stockpile area <br />located at the east side of the affected land area (Ses Exhibit C, Mine Plan Map, <br />
