DRILL HOLE ABANDONMENT <br />The holes as currently planned are all within the mining envelope. Abandonment and closure will be by mining. <br />If mining ceases before closing the hole, or if a hole location is moved to be outside the mining envelope, then <br />those holes will be sealed with a pelletized bentonite product to ten feet above the static water level. The pellets <br />will be adequately sized to allow complete backfilling of the hole below the ten foot above water level line without <br />bridging. The top of the hole will be plugged with concrete from 3 feet to 13 feet below ground level. The holes <br />will not be developed as water wells. <br />Table 2.05.3(3)10-6 show the worst-case estimated reclamation cost for drill hole abandonment. It is worst-case <br />because it assumes that mining will cease before any hole is closed by the normal mining process. The estimated <br />cost is $10,218.14. However, that amount is reduced by $3,676.94 because the $3,676.94 amount represents <br />bonding for the 2005 Drill Program approved, but never implemented, as detailed above, in pages 19 -23 of this <br />attachment. The 2005 Program was not drilled due to poor drill rig availability. So, total net increase in bond <br />amount for the 2005 Fall Drilling is $6,541.20. <br />(Revised 09/05) Attachment 2.05.3(3)10- 26 <br />
