  • DEPOSIT IS OPEN AT DEPTH, RESERVE/RESOURCES CALCULATED TO 1150 METERS. BLAIR REPORTS ONE SOURCE CLAIMS THAT 300,00 MT/Y MASSIVE SULFIDE ORE BODY CONTAINS 3.5-5% NI.

Comments on the workings information

  • UNDERGROUND MINING WILL FIRST TAP A ZONE OF MASSIVE SULFIDE MINERALIZATION LYING RELATIVELY NEAR SURFACE

Comments on development

  • AN EXPLORATION SHAFT IS BEING SUNK TO A DEPTH OF 895M TO PROVIDE ACCESS FOR AN EXAMINATION OF THE DEEPER ZONES. IN MINING THESE OREBODIES, ORE WILL BE HOISTED TO THE SURFACE AT INITIAL RATE OF 700000 MTPY. OPERATIONS WERE SUSPENDED IN 1988. ; ECON.COM: TOTAL PREPRODUCTION EXPENDITURE, INCLUDING EXPLORATION, EVALUATION, CONSTRUCTION AND DEVELOPMENT IS ESTIMATED AT A$102 MILLION

General comments

Subject category Comment text
Deposit ORE WILL BE MILLED AT THE MINE TO PRODUCE NI CONCENTRATE AT A PLANNED RATE OF 85000 MT/Y, CONTAINING 10000 MT OF NI. THE CONCENTRATE WILL BE SENT BY RAIL TO WESTERN MINING CORPORATION'S SMELTER NEAR KALGOOLIE FOR TOLL SMELTING INTO A HIGH GRADE MATTE PRODUCT. AS OF 11-87, THIS RECORD INCLUDES DATA FROM RECORDS M046843, W700809, AND M046831 WHICH HAVE BEEN DELETED FROM MAIN MRDS.
Deposit NEAR SURFACE THERE IS MASSIVE SULFIDIC ORE AND THE DEEPER OREBODIES ARE DISSEMINATED, CONSTITUTING THE MAJOR PART OF THE RESERVES.
