The excavated material from the drill site will be stored as berm material to be used exclusively <br /> for backfilling-at the drill site. <br /> 2. The approximate area of 16x80 ft.will receive the excavated materials by constructing a <br /> temporary berm in a manner to control erosion@ the North end of the Santiago#1.This area is <br /> easily accessible,when material is to be transported back to the drill site for backfilling.All <br /> material will be held in place and designated for back fill only at the drill site.In the event of any <br /> shortfalls of material for any reason,there is available more of the exact same material for any <br /> shortfall. <br /> This unique occurrence of talus and glacial moraine material has qualities of early compaction, <br /> and the til-clays make for a quality planting medium. <br /> I have included a few photos showing this quality just under the rough surface of the talus.A <br /> photo of the 5t'Level working platform will show an examination of the compacted area's natural <br /> reseeding of wildflowers and grasses. As a naturalist,it is my intent to protect this environment <br /> of this unique caldera area for all time. <br /> 3. The time line of permanent abandonment of drill site is unknown.The enclosed sketch may <br /> clarify backfilling intents and procedures.The drill collar will be left open and in place for <br /> emergency use or for additional use for further exploration paralleling the Santiago#8 vein.A <br /> PVC 3 ft. sleeve to be placed over the drill collar and backfilled to excavated grade, leaving <br /> approximately 6 inches to accommodate the PVC cap.An 8 x4 inch x 2 ft. square wall with a 3 <br /> inch thick concrete cap will give additional protection to the drill collar,while providing easy <br /> access for and further use down the road.When permanent abandonment is scheduled,backfilling <br /> will be on top of the enclosure to original slope or grade. <br /> Respectfully Submitted, <br /> !Santiago <br /> ephen it s, si Mining omp y LLC <br />
