March 2, 1994 -2- 933-2714 <br />Attachment 2 includes an aerial photograph of the Creede azea looking to the north. Surface <br />water drainage is from north to south with Willow Creek entering the Rio Grande river <br />' south of Creede. Attachment 2 also includes several photographs of features in the area. <br />Photograph 1 shows the Commodore Mine with the Commodore Nos. 3, 4, and 5 portals <br />from bottom to top. Photograph 2 shows the entrance of the Nelson Tunnel, which is <br />located near the Commodore No. 3 portal. Photograph No. 3 shows the locadon of the old <br />Humphrey Mill site which is located near the confluence of West and East Willow Creek. <br />This mill is reported to have produced the old tailings that are present in the flood plain of <br />' Willow Creek south of Creede. The tailings pile east of Willow Creek below Creede were <br />produced from later operations at a different mill. Photograph No. 4 is looking north from <br />- Creede. Willow Creek is to the right and Windy Gulch is to the left. It shows the major <br />t topographic divide between Windy Gulch and Willow Creek. Elevations on top of the <br />divide exceed 10,000 feet. Photograph No. 5 is looking up Windy Gulch from the Willow <br />Creek Road. The photograph was taken within about 100 feet of the confluence of Windy <br />' Gulch and Willow Creek. Photograph No. 6 shows the confluence of Windy Gulch and <br />Willow Creek. It was taken near the same location as Photograph No. 5. <br />' Geolgp_ic Framework <br />Attachment 3 includes portions of a geologic map of the region. It shows the major <br />' northwest-southeast trending faults along which the major mineralized zones occur. The <br />workings of the Bulldog Mine are along a different fault zone than the Commodore Mine <br />and the other mines that are interconnected to the Commodore. <br />' The Bulldog Mine workings are located in Tertiary volcanic rocks consisting of rhyolite and <br />welded tuff. The geologic map included in Attachment 3 shows the distribution of units. <br />' The primary units in the mine area are the Bachelor Mountain Rhyolite (Tbm) and the <br />Wason Park Rhyolite (Tw). In the northwestern part of the mine the Huerto Formation <br />(T'h), which is also a rhyolite unit, is present. South of the mine the Creede Formation (Tc) <br />consisting of volcanic sediments and calcareous tufa is present. The volcanic bedrock in <br />portions of the mine area is covered by Quaternary landslide deposits (Qls). Quaternary <br />' glacial deposits (Qgm) are found in the upper portion of the Windy Gulch drainage. <br />The volcanic rocks in the mine area are dense welded tuffs and will have low hydraulic <br />' conductivity except in areas of significant fracturing. Thus, zones of groundwater flow <br />primarily will be associated with the major northwest southeast trending structures in the <br />area. Interstitial flow in the volcanic units will be negligible. <br />' Attachment 4 is a composite level map of the underground workings in the Creede area. <br />The Bulldog workings extend northwest along the west side of Windy Gulch for about 8,000 <br />ft The Commodore workings extend northwest on the west side of West Willow Creek for <br />over 15,000 feet and interconnect with workings in the Last Chance, Amethyst and Happy <br />1 <br /> <br />
