Thomson Resources Ltd.: Aeromagnetic Survey Commenced; Second Phase Drilling Complete
29.09.2015 | ABN Newswire
Sydney - Thomson Resources Ltd. (ASX:TMZ) is pleased to announce that it has commenced an aeromagnetic survey over a strong magnetic anomaly at Mullagalah, near Bourke, NSW and completed Phase 2 drilling at its Bygoo tin project.Bygoo Project
5 holes for 600m have been drilled in the second phase of drilling at the Bygoo tin project near Ardlethan, NSW. Substantial, multiple mineralised greisens were intersected in three of the five holes. 260 samples have been dispatched and assay results are expected by mid-October.
Mullagalah Project
The survey will comprise 1,194 km of surveys at a line spacing of 50m, providing high resolution magnetic and radiometric data to detail the prominent anomaly.
The anomaly lies on Thomson's EL 8102, which is the subject of a farm-in. The survey is being funded by Thomson's farm-in partner, which will see the private investor earn a 50% interest in the tenement.
The Mullagalah anomaly has previously been explored by YTC Resources Ltd in 2010, who drilled two deep diamond holes near the edge of the anomaly (Table 2, in link below). Both holes intersected anomalous copper and gold with accompanying mineral alteration of the types often found in intrusion-related mineralisation.
The intrusion is of quartz-granodiorite to tonalite composition, medium-K, calc-alkaline and I-type in character and dated at 414.9 million years old (+/- 4.2Ma, Early Devonian).
This is similar in age to the mineralising events that were taking place in the Cobar Basin to the southwest.
The intrusion lies on major structures (blue lines in Figure 1, see link below) and its pattern is suggestive of significant deformation, thought to be necessary for the mineralizing process.
Thomson considered that the existing magnetic data was too coarse to provide compelling drill targets and that a high resolution survey could identify discrete targets - either magnetic highs caused by pyrrhotite related mineralisation or magnetic lows caused by destructive alteration of magnetite to pyrite related mineralisation.
