Logan Wash Mine Annual Report
<br />Permit No.: M-7977-424
<br />Well LW-22 is located adjacent to Well LW-242 in SEl/4 SEl/4 SW1/4, 527, T7S, R97W. The
<br />well is 83.6 ft deep, depth to water was measured to be 7.8 ft, and the well has a 5-inch inside
<br />diameter casing. The well was sampled on November 10'h, 2005 at the request of Mr. Prather.
<br />Mr. Prather is planning on using water from the well upon establishing an agreement with the
<br />BLM. Well LW-32 is located in the NE1/4 SW 1/4, 524, T7S, R97W. The depth to water was
<br />measured to be 253. 65 fr. The depth of this well is greater than 1000 ft. Well LW-45 is located
<br />in NEl/4 NEl/4, 519, T7S, R96W. The depth to water was measured at 247.6 ft in the annulus
<br />space. The annulus total depth is approximately 595 fr, and the inside diameter is 7 inches. A 2
<br />3/8-inch tubing inside of the 7-inch casing is obstructed at a depth of 8.65 ft. Well LW-1 ] 6 is
<br />located in the NW 1/4 NW ]/4, S20 T7S, R96W; no data is available for this well. Well LWCW-
<br />lA is located in the SEl/4 NW 1/4, S25, T7S, R97W. This well was drilled in 1999 as a down-

<br />4.9 Removal of Reclamation Fence Materials
<br />Reclamation fencing originally installed to protect previously revegetated areas along the Logan
<br />Wash access road was removed and stockpiled in 2004. The stockpiled material was removed
<br />during this reporting period. Fencing consisted of barbed wire, metal T-posts, and wooden fence
<br />posts. Areas where fencing was removed include Area 6, 20, B2-B5, as shown in Exhibit F in the
<br />mine permit. All areas where fencing was removed contained well-established native vegetation.

<br />Re-grading with conventional excavation equipment consisted of grading on previously disturbed
<br />areas to construct the rip-rap and non rip-rap storm water drainage channels on the Research
<br />Mine and Lower Bench, and other drainage channels such as toe drains and v-ditches along the
<br />Upper and Lower Bench roads. Re-grading was also conducted at the new Soil Barrow Area
<br />prior to revegetation to contour and modify the slope to a grade less than or equal to 3 fr
<br />(horizontal) to 1 ft (vertical).
<br />4.11 Release of Warranty for Reclaimed Land
<br />On August 29°i, 2005, DMG conducted a site inspection of lands meeting reclamation
<br />requirements. The visit was originally requested by OOSI in January of 2005 and was revised in

<br />5.0 Maintenance Activities
<br />Maintenance activities included periodic inspections of mine roads, portals, mine water drainage
<br />systems associated with the retorts and general mine workings, as well as inspection of general
<br />evaporation pond operation, security, and leak detection system. Maintenance activities
<br />conducted at the mine and Pond 1 are summarized in the following sections.
<br />5.1 Mine Maintenance
<br />During the reporting period and while site reclamation work was being conducted, GSHI
