Exhibit 71 Hydrologic Characterization South of [he Divide Area and Monitoring Plan 24 <br />4.4.1.3 SpY7nQ 26-1 <br />Spring 26-1 is located in a drainage on the west side of the Deep Creek drainage between the Upper and <br />Lower Deep Creek monitoring stations (Map 1), Deep Creek is tributary to Raven Gulch and the North <br />Fork of the Gunnison River. This spring is above the east side of mine Panel 15 (Box Canyon mine panel <br />area) and issues from a sandstone bed above the F-Seam. This spring has perennial flow but shows strong <br />seasonal vaziations with high flows in the spring months. Monitoring at this spring began in 1996. <br />4.4.1.4 Seep E14-1 <br />Seep E14-1 is located in upper Box Canyon which is tributary to the North Fork of the Gunnison River <br />and is above the Box Canyon panel area (Map 1). This seep issues from a sandstone bed above the E- <br />Seam and has never flowed. It is damp only during very wet spring months, but is typically dry. <br />Monitoring at this seep began in 1998. <br />4.4.1.5 SDY[nQ 27-1 <br />Spring 27-1 is located in upper Sylvester Gulch, tributary to the North Fork of the Gunnison River, (Map <br />1) and feeds an area known as "twin ponds". This spring issues from alluvial sediments and is above the <br />south side of mine Panel ] 5 (Box Canyon mine panel area). Hydrologic monitoring measurements from <br />this station are taken at the end of a plastic drain pipe. Monitoring at this spring began in 1996. <br />4.4.1.6 Spring G-7 <br />Spring G-7 is located in a western tributary of Sylvester Gulch and is south of the NE mine panel azea and <br />north of the SE panel azea (Map 1). This spring issues from joints in a sandstone ledge and has perennial <br />flow, but shows strong seasonal variations with high flows in the spring months. Monitoring at this <br />spring began in 1977. <br />4.4.1.7 SDYinY G-16 <br />Spring G-16 is located in Sylvester Gulch east of the NE mine panel area (Map 1). This spring issues <br />from a sandstone bed above the F-Seam and flows seasonally. It is typically dry in the late summer and <br />fall. Monitoring at this spring began in 1979. <br />4.4.1.8 SDrinq G-24 <br />Spring G-24 is located in Sylvester Gulch east of the NE mine panel azea (Map 1). This spring issues <br />from alluvium and is measured at the outflow of a plastic drainage pipe. It flows seasonally and is <br />typically dry in the late summer and fall. Monitoring at this spring began in 1979. <br /> <br />Apri12006 HydraGeo, Ine. <br />
