~~ <br />.~ <br />2. Describe what and where reclamation activities have occurred in the past 180 days. <br />Mention sealing and plugging, regrading, retopsoiling and reseeding activities. (Attach <br />additional pages, if needed.) <br />All abandonment and reclamation activities have followed procedures set by the Bureau of Land <br />Management. Abandonment sealant consisted of either 1-100 pound or 2-50 pound bags of <br />"Bore-Gel" bentonite, mixed with 100 gallons of water per pound in a 200 gallon stock tank. <br />Once the hole was drilled to total depth, it was blown clean of cuttings and the mixed sealant <br />pumped through the drill string, until the sealant circulated to the top of the hole. The drill pipe <br />was then "tripped" out of the hole and additional sealant pumped into the hole, as the drill pipe <br />was withdrawn. In all cases, the sealant level would drop to the top of the unweathered bedrock, <br />typically at a depth between 10 and 20 feet. The drill rig would then move off the hole and onto <br />another location. Each of the holes was logged with geophysical tools. After logging, <br />Southwestern Construction of Nucla, Colorado, would complete final reclamation of each hole by <br />dumping 3-50 pound bags of bentonite chips into the hole, then shoveling cuttings into the hole to <br />a depth of 10 feet below the surface. The final ten feet of hole was then filled with sackrete. An <br />aluminum survey monument labeling each hole was set in the concrete at the surface. See <br />attached figure for diagram (Figure 1). Any remaining cuttings were removed or dispersed and <br />the area seeded with the approved seed mixture. <br />3. List any additional changes to the original prospecting and reclamation plan or any <br />unexpected problems (such as unexpected water or artesian conditions <br />encountered). (Attach additional pages, if needed.) <br />No changes were made and no unexpected problems were encountered. <br />
