(Lien) proposes to conduct <br />exploratory drilling within the permit boundary of the subject active permit. Recent geologic <br />mapping suggests the need for Lien to better define the geometry of the ore body within the <br />subject permit boundary. Our bond will more than adequately cover the minimal disturbance. <br />Lien proposes to drill six (6) to 10 three (3) inch outside diameter core holes, and six (6) to 10 air <br />hammer holes for the purpose of reserve analysis. All holes will be reclaimed concurrently, and <br />no mare than two (2) drill holes will be open at any given time. Holes will be drilled to a depth of <br />20 to 100 feet, and reclaimed using cuttings, and concrete. Previous drilling and mining suggests <br />that @•oundwater is well below the proposed drilling depths. However, if groundwater is <br />encountered, Lien will take measures to prevent the mixing of formation waters. <br />Lien proposes to access the drill holes via the permitted right of way and via cross country travel. <br />No additional roads are required to be constructed for disturbance related to this project. Lien <br />does not anticipate the need for drill pad construction. However, it is the policy of Lien to <br />maintain a safe working environment for equipment and personnel; therefore, pad construction <br />will be assessed on a case-by-case basis, and disturbance should be limited to the removal of non- <br />pro[ected plant species, and colluviums. <br />Equipment required for this project will be used on a strictly "as needed" basis and include, but <br />are not limited to the following: core rig, air hammer rig, pick-up truck(s), water truck, and pipe <br />truck. <br />
