Sunnyside and Mogul mines (at an elevation of 11,904 feet msl-, access to that <br />tunnel is so difficult that it is more convenient to place two sets of bulkheads at <br />locations before the workings converge to a single tunnel. There also exists a <br />connection between the Sunnyside Mine and the Gold Prince Mine (with a portal in <br />Placer Gulchl, but the connection is at least 150 feet higher than land surface in the <br />Sunnyside Basin. <br />Once an equilibrium water level is established in the flooded mine workings land <br />perhaps even earlier) some water is expected to move along natural fracture pathways <br />from the flooded mine workings toward the Cement Creek Basin. The natural pre- <br />mining ground-water flow directions (discussed in Section 3.41 are expected to be <br />reestablished. The majority of the ground-water flow is expected to be toward the <br />west and southwest as indicated on Figure 8. Most of the permeable fractures are <br />oriented southwest, but the Brenneman vein also appears to be somewhat permeable <br />and is oriented west-northwest. The estimated rate of ground-water flow through the <br />flooded mine workings is discussed in Section 8.2 and the transit time from the mine <br />workings to the surface is considered in Section 8.3. <br />cunnylwp\traci~2251 \Mar1993.
