Bulolo Gold Deposits
nULOLO Gold Deposits report that the re cently acquired area of 50 acres (previously advised as 45 acres) adjoining the Morobe area is estimated to contain 2,500,000 cubic yards of alluvials with average values of 1/3 a yard. This property will be worked from the company’s pre
sent water race. The manager states that 20,000 cubic yards a month can be treated at a cost of 4d a cubic yard. Sluicing will be begun on this area about the end of July.
Owing to late delivery of material the instal lation of the elevating plant rn the Morobe pro perty has been delayed, but it is expected that operations on a larger scale will be reached by the beginning of July. In the meantime sluicing operations are being continued on this area and on the Bulolo terraces.
