Varhus ~ QiYisipnof' <br />Department of Energy Minerals~CA41G6~ <br />Grand Junction Projects Office <br />P.O. Box 2567 <br />Grand Junction, CO 81502-2567 <br />Subject: Mining Lease No. AT(OS-1)-ML-60.8-C-JD-5 <br />Mining Lease No. AT(OS-1)-ML-60.8-.C-SR-13 <br />Dear Mr. Varhus: <br />Blake Mining Company was assigned the subject leases in late <br />1993 and has recently sent you a letter indicating Blake Mining <br />Company's intent to renew these same leases. <br />Both leases contain surface structures which are considered <br />to have historical value and which should be allowed to remain in <br />place after mining and subsequent reclamation have been completed. <br />These structures consist of the headframe at the JD-5 shaft and <br />the small steel ore bin at the portal of the Hawkeye Mine on SR- <br />13. Both structures are described and recommended for <br />preservation in the report "URAVAN MINERAL BELT, Inventory of Mine <br />Sites in the San Juan and Umcompahgre Basin Resource areas of the <br />Bureau of Land Management, Summer 1994". This report was prepared <br />by Timothy Kramer and Randall Patrick of ECO Associates. The <br />appropriate sections of this report are attached for your <br />reference. A complete copy can probably be obtained from the <br />Bureau of Land Management. If not we will provide one if you so <br />desire. Each structure is described in detail, as follows: <br />: JD-5 Headframe: This is a small steel structure in <br />excellent condition above a concrete-lined circular mine <br />shaft, 16 feet inside diameter. The structure is solidly <br />supported on concrete foundations. It was constructed in <br />1974 or 1975 and is an excellent and well preserved <br />example of a modern small headframe. It is an appropriate <br />memorial to what may become the final era of uranium <br />mining on the Colorado Plateau. <br />* Hawkeye Ore Bin: This is a small steel ore bin and timber <br />retaining wall. It is located at the Junction of Colorado <br />Highway 141 and the road to the Hurro Canyon mines and <br />Slick Rock mill site, approximately 1/4 mile east of the <br />Slick Rock store and cafe'. Because of its location and <br />uniqueness, it is frequently photographed by tourists <br />either driving along Highway 141 or rafting on the nearby <br />Dolores River. It was constructed in the early 1950's and <br />is an excellent example of the surface development that <br />was typical of Colorado Plateau uranium mines of that era. <br />~>] <br />
