Comments on the geologic information

  • THE DIKE IS SPODUMENE-RICH WHERE THICKEST, BUT PERTHITE-RICH ELSEWHERE. THE PEGMATITE IS MADE UP OF 2 ELONGATE BULGES, THE UPPER SPODUMENE-POOR BULGE IS EXPOSED AT THE SURFACE (170 FT X 50 FT). THE LOWER BULGE IS SPODUMENE-RICH AND RESULTS FROM DIAMOND DRILLING SHOW IT TO BE LARGER THAN THE UPPER BULGE.

General comments

Subject category Comment text
Deposit THE MAIN PEGMATITE COMPRISES FIVE WELL DEFINED ZONES. (1) A DISCONTINUOUS OUTER SELVAGE OF QUARTZ, ALBITE, MUSCOVITE, AND SCHORL, ALSO MICA. (2) THE WALL ZONE ( 2 TO 55 FEET THICK ) OF PERTHITE, QUARTZ, ALBIE, AND MUSCOVITE IS MOSTLY COARSE GRAINED. (3) THE OUTER INTERMEDIATE ZONE IS COARSE GRAINED BLOCKY PERTHITE. TOURMALINE IS LOCALLY ABUNDANT. (4) THE INNER INTERMEDIATE ZONE HAS VERY COARSE PERTHITE AND MASSES OF QUARTZ. (5) THE CORE IS ARBITRARILY DESIGNATED AS HIGHER GRADE FELDSPAR THAN THE PREVIOUS ZONE.
