Economic information about the deposit and operations

Development status Producer
Commodity type Non-metallic
Significant No
Discovery year 1965
Year of first production 1967

Mining district

District name Kajiado

Ownership information

  • Type Operator
    Owner Ceramic Industries Of East Africa

Comments on the production information

  • PRODUCTION LEVEL IS SMALL.

Comments on the reserve resource information

  • RESERVE ESTIMATES ARE BASED ON 800 FT LONG BY 30 FT (27% WOL) OR 50' (18% WOL) BY 100 FT DEPTH (INFERRED). THE RATIO OF WASTE TO ORE WOULD BE 3:1 FOR THE 27% ORE AND 5:3 FOR THE 18% ORE.

Comments on development

  • ECON.COM: IT IS 6 MILES BY DIRT ROAD TO KENYA MARBLE QUARRIES, WHICH ARE SITUATED ON THE MAGADI-KONZA BRANCH RAILRAOD LINE (325 MI FROM PORT OF MOMBASA). THE MARBLE QUARRIES ARE ALSO NEAR THE NAIROBI-NAMANGA ROAD. LOLKIDONGAI HAS POOR WATER RESOURCES-- THE NEAREST BORE IS AT MARBLE QUARRIES. LOLKIDONGAI PRODUCES A FLOTATION CONCENTRATE OF ABOUT 85% WOLLASTONITE THAT IS EXPORTED TO EUROPE.

General comments

Subject category Comment text
Deposit WOLLASTONITE OCCURS WITH LIMESTONE AND MARBLE ASSOCIATED WITH MIGMATITIC, PELITIC AND SEMI-PELITIC ROCKS. THE DEPOSIT OUTCROPS ON 3 LOW HILLS (WESTERN, NORTHERN, AND EASTERN HILLS) THAT FORM A CRESCENT-SHAPED RIDGE ABOUT 2.5 MILES LONG. THE DEPOSIT IS MAINLY ON EASTERN HILL WHERE MARBLE IS THE DOMINANT HOST. THE WOLLASTONITE-MARBLE STRIKES ENE AND IS INTERBEDDED WITH WOLLASTONITE-FREE MARBLE. IN OUTCROP, THE WOLLASTONITE BEDS ARE 1500 FT BY >100 FT, BUT ORE IS SMALLER AREA.
