INTRODUCTION <br />Mount Royale Ventures, LLC ("MRV") holds Division of Reclamation, Mining and Safety, Colorado <br />' Department of Natural Resources Permit M-1983-141 for the mining of the Cash Mine, Boulder County, <br />Colorado. <br />' This report contains the Comprehensive Water Monitoring Plan required pursuant to that Permit. <br />2. SETTING <br />' 2.1 Location <br />' The Cash Mine is located in Section 12 Township 1N Range 72W 6a' Principal Meridian, at a surface <br />elevation of approximately 8,000 feet msl on the flank of a steep ridge neaz Gold Hill, Colorado. The <br />mine location and the surrounding area aze shown in Plate 1. <br />' 2.2 Precipitation <br />The precipitation at Gold Hill, half a mile from the site, averages 19.5 inches per year', with the peak <br />' occurring in April and May. Winters are in general relatively dry. <br />2.3 Geology <br />1 <br /> <br /> <br />The geology in the vicinity of the Cash Mine comprises a shallow mantle of soil (typically a few feet or <br />less thick) overlying Precambrian Boulder Granodiorite, which is described as "grey, pinkish gray to <br />black and white medium-grained to very coarse grained locally porphyritic rock composed of microcline, <br />plagioclase, and quartz, and lesser amounts of biotite and hornblende" Gable (1980)2. The gold ore is <br />contained in quartz veins and other local intrusives located along faults and major fissures in the country <br />rock. <br />2.4 Structure <br />The rock fabric in the vicinity of the Cash Mine is shown in Plate 2'. The district has a significant <br />number of large veins and faults, frequently oriented approximately NE-SW, and crossing structure <br />approximately normal to the main fabric. The orebodies in the district are in general located on the main <br />structures. The structures in the district also generally comprise permeable conduits in the rockmass. <br />' http://www.city-data.com/city/Gold-Hill-Colorado.html <br />2 Gable, D.J., 1980.
