Comments on the reserve resource information

  • RESERVES INSIGNIFICANT; PROBABLY 200 TONS AVERAGING 2.0+CO COULD BE RECOVERED FROM EXISTING OPERATIONS IF AN INVENTORY OF THE WHOLE DISTRICT WERE MADE, IT MIGHT SHOW A RATHER LARGE TONNAGE OF LOW-GRADE ORE(0.3-0.5% CO)SCATTERED IN A NUMBER OF SMALL DEPOSITS. IN SOME AREAS WHERE STRUCTURAL CONDITIONS ARE FAVORABLE, IT IS POSSIBLE THAT OTHER CU-CO BODIES MAY BE DISCOVERED AT DEPTH. MOST KNOWN LENSES ARE IN SHALLOW WORKINGS
