dc.description.abstract | The Sylvester project is located in the Barkly Tablelands of the Northern Territory, 220km northeast of Tennant Creek and 120km north of the Barkly Homestead Roadhouse. The Tablelands Highway passes through the centre of the area. The project consists of two exploration licences: EL23683 Lower Sylvester and EL23685 North Sylvester. The area was identified as conceptual target area based on proprietary methods and modelling conducted by Paradigm Geoscience Pty Ltd. A review of previous exploration work confirmed the prospectivity of the area with a large number of microdiamonds reported by previous explorers. While the diffuse spread of microdiamonds over much of the NT has been well described, the Sylvester area is characterised by microdiamond abundances well above the general background level. The microdiamonds are spread over an area of approximately 3000km2 and there is no obvious centre/s to the anomaly, presumably due to the surficial processes, poor drainage and large areas of shallow cover. In order to characterise the microdiamonds found in the Sylvester region, the company compiled previous diamond exploration data over an area of 10,000km2 and then reviewed, classified and tabulated descriptions of all microdiamonds described. When the microdiamonds are classified into three simple categories (common, rare and very rare types), it becomes evident that there is a cluster of rare/very rare types in the centre of the area, surrounding EL 23685. This provides good evidence for a local source of the diamonds and confirms the prospectivity of the area. Reconnaissance exploration has led to the conclusion that standard surface exploration methods would not be effective in tracing the microdiamonds to their source. During the fourth year of exploration a program of auger drilling was undertaken since it would be better suited to assess the potential of the project area than surface sampling methods. Unfortunately this work failed to identify the source of the microdiamonds in the area, nor did it identify any samples with anomalous geochemistry. It has been decided to surrender both ELs thus allowing Crossland Uranium Mines Pty Ltd to focus its resources and efforts on other projects.on other projects. | en_US |
