EXHIBIT C <br />Mining Plan <br />The Robins Rock Pit will first be stripped of "top soil" in the area to be mined. The estimated depth to <br />which soil suitable for plant growth medium will be removed is 6 inches, although the depth will vary. <br />Because the products from this pit must be clean, all fine material will be separated with a power <br />screen, and this material will be added to the topsoil stockpile. This top soil material will be stockpiled <br />in an area on the west side of the irrigation pond as shown on the accompanying map. After top soil is <br />removed and stockpiled, a drilling program will commence in the area to be mined. The drill pattern will <br />be determined based on an initial pattern of 3 feet by 5 feet drilled to a depth of approximately 18 feet. <br />If this pattern is sufficient to produce the required results, then the pattern will be maintained; if not the <br />drilling pattern will be modified as necessary. This drilling will result in a highwall along the north and <br />south perimeter of the pit, so a barrier of large rocks and or safety fence will be placed along the <br />perimeter to prevent livestock and human traffic from accidentally falling into the excavated area. The <br />Loading area is immediately west of the irrigation pond. Rock processing will be minimal since the <br />intended use for this material is for "J" hooks in an NRCS sponsored reclamation project on the Conejos <br />River and as ballast for the Cumbres & Toltec Scenic Railroad. Product will be moved from the loading <br />area to the nearby Conejos County Rd H via an existing 10 foot wide unimproved farm road which has <br />been used as an access road to service and fuel the irrigation pump at the pond. No further <br />improvements to this haul road are anticipated Mining is anticipated to begin in 2007 and run through <br />2011, processing approximately 50,000 tons per year. A mining plan map is included herewith.
