Deposit DURING THE PAST YEAR, GEOLOGICAL INVESTIGATIONS WERE UNDERTAKEN TO ESTABLISH THE VIABILITY POTENTIAL OF THE KIMBERLEY REEF ON THE AREAS UNDERLYING THE OLD SPRING MINE. IN THIS REGARD, AN APPLICATION FOR THE GRANTING OF 7,196 PRECIOUS METALS CLAIMS HAS BEEN LODGED WITH THE GOVERNMENT MINING ENGINEER. IN ADDITION, AN INVESTIGATION WAS UNDERTAKEN TO DETERMINE THE PROFITABILITY OF MINING ORE FROM THE BLACK REEF ON A TRIBUTE BASIS. A DECISION IN THIS RESPECT HAS NOT YET BEEN FINALISED.
