Comments on the commodity information

  • SB IS ENRICHED BY AN ORDER OF MAGNITUDE IN THE ZONE OF AU MINERALIZATION THOUGH IT LACKS A STRONG LINEAR CORRELATION TO AU. AS IS ENRICHED FOURFOLD IN THE ZONE OF 0.5 PPM AU MINERALIZATION. TL IS GENERALLY PRESENT IN QUANTITIES >5 PPB WHEN AU CONTENT IS >100 PPB; A MODERATELY STRONG LINEAR RELATIONSHIP BETWEEN AU AND TL IS OBSERVED. MO IS ANOMALOUS AT THE DETACHMENT FAULT THOUGH NOT STRONGLY CORRELATABLE WITH AU. AG GENERALLY OCCURS IN LOW CONCENTRATIONS WITH AN OVERALL AU:AG RATIO OF APPROXIMATELY 4:1

Comments on development

  • BASED ON AN EXPLORATION MODEL PUBLISHED BY CORN AND AHERN (1981), U. S. BORAX LOCATED CLAIMS OVER THE LENGTH OF FLUORSPAR CANYON AND PARTIALLY SURROUNDED THE CROWELL FAMILY CLAIM GROUP. A DRILLING PROGRAM BY U. S. BORAX TESTED FOR MINERALIZATION IN THE HANGING WALL OF THE FLUORSPAR DETACHMENT FAULT, WHICH LED TO THE DISCOVERY OF THE SECRET PASS ZONE.
