NEW GUINEA GOLD: SINIVIT MINE UPDATE
New Guinea Gold Corp.'s drill results at its Sinivit gold mine have extended the known oxide gold mineralization in the Central Oxide zone. Fourteen RC drill holes (of a total of 21 drill holes) returned average gold results above mine cut-off of 1.5 grams per tonne gold. Best results were eight metres at 12.82 g/t gold, underlying two m at 38 g/t gold; six m at 10.45 g/t gold including two m at 19.30 g/t gold; four m at 19.60 g/t gold including two m at 37.60 g/t gold. All results are shown in the accompanying table.
Process Enhancement
An on-site review of Sinivit by NGG staff and experts associated with our Normanby joint venture partners have concluded that it would be appropriate to proceed to heap leaching at Sinivit and gradually phase out the vat leaching. The heaps would be constructed on top of existing vats. Normally, with heap leaching it is necessary to have "pregnant and barren" ponds associated with heaps to retain solution. In the case of Sinivit, the underlying vat serves as the "pregnant pond" and the barren solution is re-circulated straight to the heap. Heap leaching will result in lower operating costs than vats. The first trial heap leach should be operating within four weeks.
If heap leaching provides similar or better recoveries to vat leaching, NGG's capacity to process mineralisation in a more timely fashion will be greatly increased. Based on the existing vats, total heap capacity at present, is estimated to exceed 200,000 tonnes of mineralisation. In addition to the heap leach trial, the Company's new vat capacity available to-date is around 30,000 tonnes. Approximately 8,000 tonnes have been placed in Vat 5 over the past few days. On the expert advice above, NGG will also be trialling revised methods of fluid circulation in these vats which may increase recovery.
Crushing capacity has improved significantly over the past quarter with approximately 11,000/12,000 tonnes/month being achieved. NGG expects to achieve 15,000 tonnes in May. The Company, in the near future, will implement extended crushing shifts under lights. This, together with the new crusher, is expected to allow a finer crushed product (100% minus 6-8 mms) and achieve as much as 20,000 tonnes/month of crushed product.
Tellurium Recovery
In respect to tellurium, World Industrial Minerals of Denver, Colorado, have indicated interest in proceeding to further evaluation of the potential to extract tellurium at Sinivit. Representatives will visit the Operations Office in Queensland, Australia early in June, and then proceed to Sinivit for further evaluation.
