Comments on the workings information

  • DISTRICT ELEC. POWER NET SERVES ALL MINES WATER FOR THE MILL IS PUMPED FROM SHAFTS OF ABANDON MINES. PAVED ROAD PROVIDES ACCESS TO EACH MINE.

Comments on other economic factors

  • LEAD IS SHIPPED TO BELGIUM FROM NEW CASTLE FOR FINAL MARKET.
  • FRASER MINE IS ON SITE OF OLD FRASERS HUSH. IT ACCESSES GREENCLEUGH VEIN. 4 LEVELS: 380,360,340,325 METERS. GROVERAKE ACCESSES GROVERAKE VEIN AT THE 50, 60, 80 METER LEVELS. METHOD IS RETREAT LONG-HOLE OPEN STOPE. HAULAGE CONNECTS FRASER AND GROVERAKE MINES AT THE 325M LEVEL AND 60 M LEVEL, RESPECTIVELY. ORE IS REMOVED VIA GROVERAKE ACCESS. ANOTHER DECLINE IS UNDER DEV. FOR CAMBOKEELS ALLENHEAD IS AN OLD LEAD MINE. ACCESS TO THE RESERVES BENEATH THE MINE IS IN THE PLANNING STAGES.
  • MILL IS NOT BROKEN DOWN FOR THE 3 MINES. MOST IS PROBABLY FROM CAMBOKEELS, BUT NO IND. YEARLY TONNAGE GIVEN. HOWEVER, THESE 3 MINES MAKE UP THE BROADWOOD MILL. ORE IS PROCESSED BY GRAVITY PRECONCENTRATION IN DYNA WHIRLPOOL SEPARATORS, PRIOR TO PASSING ONTO THE FROTH FLOTATION STAGE. IN THE FLOTATION STAGE, BULK SULFIDE FLOAT REMOVES THE HEAVY METALS, BEFORE A COMMERCIAL OLEIC ACID FLOAT UPGRADES THE FLUORSPAR.
