Comments on the reserve resource information

ANY WHERE FROM 650,000 MT PROVEN TO 2,000,000 MT POSSIBLE. GRADE RANGE FROM 41-53 BUT GENERALLY 48-51 % IN PRODUCTS.
AREA LOCATED ABOUT 80 KM FROM RAILHEAD AT DAMAZIN. MOST OF PRODUCTION HAS COME FROM THE JEBEL GAM MINE. OTHER PROSPECTS/PRODUCERS/PAST PRODUCERS INCLUDE KURBA, SODA, CHICAY, KOMRICK, KREITER, BAU, MERI PLATEAU, AND TAGHA AS WELL AS LEASE AREA OF BAYOUMI MINERAL MINES. IN 1977 THE GAM MINE PRODUCING 720 MT ORE/WK (ABOUT 37,000 MTPY) AND LOSING 50 PCT IN SORTING (=ABOUT 18,000 MTPY) BY ONLY SHIPPING LUMP ORE.

Comments on other economic factors

LUMPS(1-15 INCHES) ARE PICKED MANUALLY. FINES (LESS THAN 1 IN.) LEFT BEHIND. MINE WORKERS ARE ASSIGNED TO HAND PICKING WHEN ENOUGH ORE HAS BEEN MINED. ORE BLENDING TO MAINTAIN GRADE IS PRACTICED. HAND SORTED ORE IS HAND LOADED ONTO TRUCKS FOR 80 KM TRIP TO DAMAZIN (2-3 HRS.IN FAIR WEATHER). ORE DUMPED INTO COMPANY STOCKPILE ALONG RR. ORE IS HAND-LOADED (UNDER CONTRACT ONTO 30 MT GONDOLA-TYPE CARS (27-29 MT/LOAD). RATIO OF TONNES MINED TO TONNES SHIPPED IS 2:1.THE 50 PERCENT REJECTED MATERIAL INCLUDES WASTE & CHROMITE FINE LESS THAN 1 INCH (2 MT MINED YIELDS .05 MT FINES, .95 MT WASTE, 1 MT ORE)
