• The procedure for the hole in the reclaimed area (OS-O1-0011) consisted <br />of drilling and sampling through the spoils and into bedrock. Chip samples <br />were homogenized and combined into 10-foot intervals for laboratory analysis. <br />Laboratory 7-aalyai• o! Lithologle Samplaa <br />Lithologic samples were analyzed for their chemical and physical <br />properties by Front Range Lab., Inc., of Fort Collins, Colorado. The <br />parameters analyzed, their unite, and the procedures are listed in Table 2.2- <br />1. <br />Laboratory 1laalyal• of Drilling water <br />Drilling was performed using air, water and a water/organic polymer foam <br />mixture in that order of preference. Water sources for each hole are provided <br />with the driller's log and locations for each water source are shown on <br />Exhibit 2.1-1. Water sources were sampled prior to drilling and water from <br />each source used was sampled as needed in the drilling program. Each sampling <br />included one bottle of water 'fixed' with nitric acid and a second 'unfixed' <br />sample. Analysis of the water samples was performed by Front Range Lab., <br />Inc., of Fort Collins. The parameters determined, reporting units, and <br />~i methods used are outlined in Table 2.2-2. <br />7lbandonmani and Raelamatioa o! 8zploration Drill 8olaa <br />Abandonment and reclamation of drill holes within the permit boundary <br />may be divided into two distinct categories; drill holes within the permit <br />boundary but not within the five-year permit term and drill holes within the <br />permit boundary and within the five-year permit term. Drill holes within the <br />permit boundary but not within the five-year permit term will be abandoned and <br />reclaimed in accordance with specific and separate exploration permits <br />obtained from the appropriate regulatory agencies and, therefore, will not be <br />discussed further in this permit. Drill holes within the permit boundary and <br />within the permit term will be abandoned and reclaimed as described in the <br />following paragraphs. <br />Exploration holes, drill holes, bore holes or other exposed underground <br />openings that will be mined through within one year will not undergo <br />abandonment procedures nor will the drill site be reclaimed. Due to the short <br />distance and time period between abandonment of the hole and mining through <br />the drill Bite with the active mining operations, complete abandonment of the <br />hole and reclamation of drill site is not considered warranted.
