Comments on development

  • SAMPLES FROM 14 PITS, TOTALLING 1 TON OF MATERIAL, HAVE BEEN SENT FOR TESTING. DISCOVERED DURING GOLD EXPLORATION PROGRAM. EXPLORATION BY DIAMOND AND REVERSE CIRCULATION WAS UNDERTAKEN. PREVIOUSLY EXPLORED BY SIKAMAN AND WHITE PLAINS RESOURCES. ; ECON.COM: WHITE PLAINS RESOURCES (VANCOUVER) OPTIONED THE PROPERTY FOR C$6 MILLION OVER ROUGHLY TWO YEARS PLUS SOME NET SMELTER RETURN CONSIDERATIONS, BUT FAILED TO EXERCISE THEIR OPTION. PRELIMINARY TESTS INDICATE THAT 60-70% OF THE RAW MATERIAL CAN BE RECOVERED AS WOLLASTONITE. PLANS ARE TO MARKET THE PRODUCT TO THE WESTERN U.S. AND THE PACIFIC RIM.

Deposit PRELIMINARY MAPPING AND DRILLING IDENTIFIED AT LEAST 3 WOLLASTONITE ZONES IN 1989. GRADES ARE VARIABLE, BUT MUCH OF THE MATERIAL IS >50% WOLLASTONITE AND OTHER ZONES AVERAGE OVER 70% WOLLASTONITE. MINERALIZATION EXTENDS TO DEPTHS AS MUCH AS 500 FT. OVERBURDEN IN THE AREA IS REPORTED TO BE NEGLIGIBLE. SITE IS 850 SQ HM (2100 ACRES) AND CONSISTS OF 124 CLAIMS ON BUREAU OF LAND MANAGEMENT LAND. THE DEPOSIT IS ESTIMATED TO BE 2133 M LONG, 610 M WIDE AND 457 M DEEP.
