dc.description.abstract | Exploration carried out within the Ewan Edward group of leases during the reporting period included: Data Acquisition and Compilation; 1:20 000 Geological Mapping; Rock Chip Sampling; Ground Gravity Survey; and Rehabilitation. As part of the regional mapping program describe above rock chip sampling was undertaken of out cropping rocks within the area. Thirty eight (38) [1665-1669, 1674-1682, 1684, 1699-1721] samples were collected. The samples were approximately 2kg in mass and located using a hand held Etrex GPS in GDA94 Zone 53 coordinates. The samples were submitted to ALS in Alice Springs for preparation before being sent on as 50g pulps to ALS in Perth for analysis. Preparation involved pulverizing the complete sample to 85% passing through 75 micron. The bowl was cleaned by pulverizing a barren sample after every sample. Gold (Au greater than 0.001ppm) analysis was done by fire assay and AAS using a 30g nominal sample weight (Au-AA25). Multi-element analysis was by an Aqua Regia digest with an ICP finish (ME-ICP41) for Cu greater than 1ppm, Zn greater than 2ppm, Pb 2ppm, As greater than 1ppm, Bi greater than 2ppm, Ag greater than ppm, Co greater than ppm, Mo greater than ppm, Ni greater than ppm, Sb greater than ppm, Fe greater than ppm, V greater than ppm, P greater than ppm and U greater than 10ppm. The best result returned was from sample No 1700 from a subcropping ironstone pod located in the northwest part of the lease returned an assay of 0.54ppmAu. A regional precision GPS-Gravity survey was carried out during September 2007 that included the southern portion of EL 25497(Henderson and Alexander 2008). The gravity survey area was extended to the north to cover a series of subcropping ironstones within EL 26221. The extension contained a further 540 stations on a 50m x 100m grid. Gravity data was acquired using a Scintrex CG-5 digital gravity meter. Position and level data was obtained using Leica GPS units to produce precise real-time- kinematic locations. All data was acquired using Daishsat foot-borne methods. Gravity data was reduced using standard reductions on the ISOGAL84 gravity network. GPS data were reduced to MGA coordinates with levels expressed as metres above the Australian Height Datum. The grid was set up concurrently with the gravity data acquisition using the Leica 1200 GPS operating in real time kinematic mode. Where possible, the readings were taken as close to the ideal coordinates as possible. At repeat stations, a washer tied to pink flagging, marked with the station number, was used for identification. At each station, the station number, position and RL were recorded digitally. | en_US |
