<br />mining methods which follow the trend of the mineral imbedded in <br />• metamorphic rock with mining operations conducted at one hundred foot <br />intervals. Tfie true extent of the ore deposit is frequently rede- <br />fined in terms of the indicated ore reserves by an on-going under- <br />ground drilling program. Also, it should be noted that although ore <br />levels are developed consecutively from higher to lower elevations, <br />simultaneous ore extraction from several different levels does occur. <br />Table D-3 <br />Resource Development Schedule <br />Location of Ore <br />Period of Scheduled <br />Ore Extraction <br />Down Through 11th Level On-going, July, 1977 <br />12th and 13th Levels P ""~ 1977-78 <br />14th and 15th Levels 1979-30 <br />16th and 17th Levels ~Q~~F~D~~~ ~ ~ 1981-82 <br />1Sth and 19th Levels 1983-84 <br />20th and 23rd Levels 1985-86 <br />• <br />Should further geologic exploration improvements in mining tech- <br />nology and the market price for uranium redefine the ore reserves to an <br />extent that requires changing the resource development schedule, Cotter <br />Corporation will notify the t4ined Land Reclamation Board and will make <br />all necessary additions to the reclamation plan. <br />D-18 <br />
