Comments on the geologic information

  • MINERALIZATION OF THE SDM BEDS IS MOSTLY OXIDES OF COPPER WITH MINOR OCCURRENCES OF COBALT-MALACHITE AND SPHEROCOBALTITE.
  • THERE ARE TWO SEPARATE MINERALIZED ZONES WHICH MAKE UP THE COPPER DEPOSITS: THE RAT BRECCIA IS ABOUT 40 METERS THICK AND THE SDM IS 30 METERS THICK; BOTH OCCUR IN THE ROAN SUPERGROUP. RAT BRECCIA IS A DOLOMITIC SANDSTONE/SILTSTONE.

General comments

Subject category Comment text
Deposit Original MRDS record W029734 lists Copper primary and Co, Au, Pt, Pd, and V all as Secondary minerals. Most of these are associated with the older Ruwe mine that predates the Mutoshi copper deposit.
