This appendix "C" represents the location of lands by legal subdivision, section, township, range, county, and municipal corporation, if any, (W.S. §35-11-406,(a),(vi)) and the number of acres in each bearing and distance description. No mining activity may take place on land for which there is not in effect a valid mining permit (W.S. §35-11-405). To include additional lands within a permit area it is necessary to amend the permit (W.S. §35-11-406,(a),(xii)), so care should be taken to include all lands necessary to the mining operation as defined in W.S. §35-11- 103,(e),(viii). Each description should state the acreage encompassed by the description and the total permit acreage should be stated. An original U.S.G.S. topographic map with the permit area clearly outlined should accompany each permit application.
