Comments on the geologic information

  • LATERITE SHOULD BE A MINERAL ENTRY; IT IS PROCESSED FOR COMMODITY CONTENT. SAPROLITE SHOULD BE A MINERAL ENTRY; IT IS PROCESSED FOR COMMODITY CONTENT. MAGHEMITE IS NOT IN MINERAL TABLE. RECENT RESEARCH INDICATES MOST OF THE NICKEL (AND PRESUMABLY THE COBALT) IS INCLUDED IN THE GOETHITE LATTICE. NICKEL AND COBALT ARE RELEASED FROM THE PARENT MINERALS AND RECOMBINED IN THE IRON OXIDES. OLIVINE IS THE PROBABLE SOURCE OF NICKEL. SOURCE OF COBALT IS UNKNOWN.
  • UNSPEC SEDIMENTARY FOR LACK OF AN APPROPRIATE ENTRY FOR LATERITE. LATERITIC SOIL COMPOSED OF HYDROUS FE-OXIDES, CLAY MINERALS, AND POSSIBLE GARNIERITE WITH RESIDUAL SILICA AND CHROMITE. SAPROLITE, THE CLAY-RICH WEATHERED HOST ROCK, IS A SIGNIFICANT, BUT VARIABLE, PERCENTAGE OF THE RESOURCE.
  • THE SHAPE OF THE LATERITE AREAS IS GENERALLY TABULAR, BOTTON IS HIGHLY IRREGULAR.
