MARATHON GOLD CORPORATION <br /> JOKER MINE AND PILOT PLANT <br /> w!r, <br /> 1986 ANNUAL REPORT <br /> CMLRB FILE NO . 83 - 52 <br /> During the period of September 1, 1985 to September 1, 1986, only <br /> very limited operations were conducted at the Joker Mine and Pilot Plant. No <br /> mining operations were conducted during the reporting period. The Pilot Plant <br /> was operated for a two week period in July for the purpose of testing material <br /> from outlying exploration targets. Approximately 100 tons of such material <br /> was processed through the Pilot Plant during the test. <br /> Laboratory use and testing of cyanide solutions in gold assay and <br /> recovery research has been suspended indefinitely and during the reporting <br /> period there was no such use of cyanide solutions. <br /> There was no disturbance of additional acreage during the reporting <br /> period. The hill above the plant was harrowed and reseeded in the fall of <br /> 1985. Sparse vegetation is growing. Reclamation of this area is progressing <br /> satisfactorily. <br /> During a MLRD inspection conducted on July 15, 1986, the staff <br /> recommended that, as a preventive measure, the topsoil stockpiles be <br /> revegetated to protect them from erosion. This recommendation will be <br /> implemented in late fall of 1986 by hand broadcasting the seed mixture <br /> specified in the permit. No erosion of the topsoil stockpiles is evident. <br /> Presently, there are no plans to disturb additional acreage or to <br /> conduct mining operations during the coming year. The Joker Pilot Plant and <br /> the laboratory may continue to be used on an intermittent basis. <br /> September 19, 1986 <br /> P.O. Box 1138 , Craig , CO 81626/303 824-8294 <br />
