1 � <br /> I <br /> J <br /> MARATHON GOLD CORPORATION <br /> 1985 ANNUAL REPORT <br /> JOKER MINE AND PILOT PLANT <br /> CMLRB FILE NO. 83-52 <br /> During the period of September 1 , 1984 to September 1 , <br /> 1985, limited metallurgical pilot plant operations were conducted <br /> at the Joker Mine and Pilot Plant . An amendment to the permit <br /> was filed in January of 1985 and approved by the Board in March <br /> of 1985 . The amendment allowed the laboratory use and testing <br /> of cyanide solutions in gold assay and recovery research. In <br /> addition the bond amount was raised from $25 ,000 to $45 ,000 . <br /> In April , use of cyanide was suspended . Detoxified <br /> pulps from cyanide tests conducted earlier this year are stored <br /> in the laboratory in polypropylene drums . There has been no <br /> discharge into the environment of solutions or solids that have <br /> come in contact with cyanide . Plans for construction of the <br /> laboratory waste disposal pit have been suspended until such <br /> time, if ever, that testing with cyanide solutions resume. <br /> The results of the water sampling program, as set <br /> forth in the amendment , are attached hereto and labeled Table <br /> 1 and Table 2. <br /> The Pilot Plant was run intermittently during the <br /> reporting period. In July a short term production test of the <br /> ores in the Joker pit was performed . An estimated 4000 tons <br /> of overburden and ore was removed . The pit face was advanced <br /> 80 feet to the south. The mined out area of the pit near the <br /> plant was back filled with overburden and tailings from the <br /> test run. <br /> Reclamation of those areas recontoured , topsoiled , <br /> and seeded during the spring of 1985 has been moderately successful . <br /> Additional seeding is planned for this fall . <br /> In September of 1985 , all operations at the Mine and <br /> Pilot Plant were suspended . The laboratory was secured and <br /> closed . Presently , only a security and maintenance person is <br /> on site . It is anticipated that operations will resume in spring <br /> of 1986. <br /> December 5 , 1985 <br /> P.O. Box 1138 , Craig , CO 81626/303 824-8294 <br /> .
