Comments on the reserve resource information

  • ITEM 2: BASED ON A COG OF 0.06% MO TO A DEPTH OF 2800 FT ASL; A VERY CONSERVATIVE ESTIMATE BASED ON UNION CARBIDE DRILLING IN 1970. ITEM 5 IS A MAXIMUM ESTIMATE, TONNAGE MAY BE AS LOW AS 200 MILLION ST.

Comments on development

  • INTERMITTENT EXPLORATION FROM PRE-1914 TO PRESENT; CORE DRILLING INTERMITTENT SINCE MID-1960'S. UNION CARBIDE IN 1970 DRILLED 26 HOLES WITH 23,000 FT CUMULATIVE LENGTH. OVER 42,000 FT OF DIAMOND DRILLING BY 1978, MOSTLY BY UNION CARBIDE AND DRACO MINES.
