REVISED Stormwater Management Plan - Golden Wonder Mine <br />(DBMS Mine Permit No.M-1978-091) <br />The following stormwater management plan (SWMP) follows the current State of <br />Colorado General Permit Application and Stormwater Management Plan Guidance for <br />Stormwater Discharges Associated with Metal Mining (and some Coal Mining) with <br />SWMP requirements outlined within Appendix B provided within : <br />http://www.cdvhe.state.co.us/wg/PermitsUnit/stormwater/SWMetalPermit.pdf All <br />recommended components of the guidance are provided by Section within this document. <br />This SWMP is a plan to reduce or eliminate pollution and/or sedimentation which might <br />occur during precipitation runoff brought about by rapidly melting snows or <br />thunderstorm activity. <br />The Golden Wonder Mine (the mine) is located about 2.5 miles southeast of Lake City, <br />Hinsdale County, Colorado in the NE % of the NE '/ Section 10, and NW % of the NW <br />of Section 11, Township 43 North, Range 4 West. The mine can be reached by <br />traveling south from Lake City on Colorado Highway 149 to Vicker's Ranch where a <br />person turns east on a private road through the ranch and up the hill past the bridge across <br />the Lake Fork of the Gunnison River. Proceed straight ahead up the road between <br />various houses to a gate (that is often locked) and up the canyon of a drainage just north <br />of Park Creek. The road crosses into the Park Creek drainage and forks north of a large <br />pond. Taking the right fork across the Park Creek valley through a series of switchbacks <br />will bring you to another fork where the right road will proceed to both levels of the <br />Golden Wonder. At the saddle, the road branches again with the right fork proceeding to <br />Level 6 and the left to Level 3. <br />1. Description of Mining Activities <br />The Golden Wonder mine is an underground gold ore mining operation. The <br />mine is owned by LKA International Inc., and currently operated by Au Mining <br />(Point of Contact: Lance Barker [970]-944-0155). However, environmental <br />permit issues and compliance are being addressed by Gault Group Inc. of Cortez, <br />CO (Point of Contact: Karmen King [970]-565-0278). <br />The Golden Wonder mine is located on a combination of patented and unpatented <br />claims. The unpatented claims are on public lands administered by the Bureau of <br />Land Management. The mine has held an active mine permit with the Colorado <br />Division of Reclamation and Mine Safety since 1978. Mining activity has <br />occurred since 1978 under operation by several leasors and ownerships. The <br />permitted area of the mine is less than 10 acres (with the combined total of both <br />the Level 3 and Level 6 areas). Within this permitted area, the current mining <br />activities include ore recovery from several underground levels accessible from <br />the Level 6 portal. The operation is relatively small scale and maintained by a <br />crew of 2 - 3 individuals. The ore is hauled out of the mine with haul cars, and <br />crushed on the working surface outside the Level 6 portal. The crushed ore is <br />sorted, placed in ore `super-sacks' and hauled to off-site for extraction. A single <br />haul truck transports the ore sacks from the Level 6 working area to a staging area <br />by Vicker's Ranch where the ore is then loaded for transport out of state. There is <br />NO extraction or smelting operations associated with the mine. <br />Historically, mining has occurred with the use of both the Level 3 and Level 6 <br />portals. The Level 3 activities were historic occurring up until about 1978 when <br />Page 4 of 16
