Annual report on the mining activities in MLN 766 Howley Project area 1989 to 1990

Abstract

MLN 766 covers a part of the Bridge Creek alluvial deposit in the northern part of the Howley Project Area. The lease lies on the western side of the Howley Ridge in the Bridge Creek catchment. The gravels are shredding from the ridge immediately east of where the Stuart Highway crosses Bridge Creek (an area called 'Bridge Creek'). The mining activities of the past year in the Howley Project Area have been focussed on the claims in this area, including MLN 766. MLN 766 is an old claim in the Howley Project Area which pre-dates the granting of the main exploration leases. It covers only a small part of the Bridge Creek orebody, so a larger ML covering the whole area was applied for and granted in August 1988. This MLN 1060 completely surrounds MLN 766 and the work done in 766 must be seen in the wider context of the total mining programme at Bridge Creek. Commissioning of the wet treatment plant at Bridge Creek began in March 1988 and mining continued through the period covered by this report. A total of 390,552 LCM's was extracted from the Bridge Creek area and stockpiled. Two water holding dams were constructed, An average grade of 0.3 g/LCM has been obtained from the gold bearing gravels. A total of 70,000 LCM's were extracted from MLN 766 in the year 1989-90 averaging 0.3 g/LCM.
