Thomson Resources Ltd. Anomalous tungsten-moly-gold F1 Assays Confirm Intrusion-Related System
16.08.2013 | ABN Newswire
Sydney, Australia (ABN Newswire) - Thomson Resources Ltd. (ASX:TMZ) report that assay results have been received from the recent drilling at the F1 anomaly. Anomalous tungsten, molybdenum and gold were returned, although no ore-grade material was intersected. The three holes, which were collared 100m apart on the eastern flank of the anomaly, have defined a clear zonation pattern.The easternmost hole, F1DD01, passed through an anomalous molybdenum zone with multiple spot highs including a best result of 1m at 0.2% Mo at a depth of 247m down hole (see Table). This sample also contained anomalous zinc (0.1%), lead (0.1%), arsenic (1%) and gold (0.1 g/t). The best gold number was recorded 10m further down hole - 0.24 g/t Au over a metre.
>F1DD02 identified anomalous tungsten, again with multiple spot highs. The best result was 0.3% W over 1m at a depth of 220m downhole.
No anomalous results were returned from F1DD03. The overall pattern between the three holes suggests a clear zonation in the F1 anomaly, pointing to potential for high gold zones to the east, possibly on the fringes of the anomaly, outside the centre of the intrusion. In other IRG systems the molybdenum-rich phase is often more closely associated with gold mineralisation, overprinting an early tungsten-rich phase.
The three holes drilled to date have tested only a small part of the anomaly area (Figure 2). Down-hole geophysical methods, such as EM, IP and magnetometry may provide discrete targets of a possible gold-molybdenum system.
Background:
The F1 magnetic anomaly is one of the largest, most intense discrete magnetic anomalies in the Cuttaburra-Falcon region (Figures 1, 2 in link below). Cover at F1 is relatively shallow at 120-130m.
F1's annular (ring-shaped) geometry and anomalous suite of metals is characteristic of Intrusion-Related Gold systems, as seen in the Tintina Belt in the Yukon (Geological Survey of Canada).
All seven other discrete anomalies tested in the region have turned out to be mineralised alteration systems with Intrusion-Related Gold affinity. Best gold results have been returned from Cuttaburra A, which lies 50km southeast of F1, with 5.5m at 1.3 g/t from 448.5m down hole which includes 1m at 3.7 g/t Au.

About Thomson Resources Limited:
Thomson Resources Ltd. (ASX:TMZ) is an Australian-based exploration company focussed on the discovery and development of high quality mineral deposits within the Thomson Fold Belt of northern NSW. Thomson Resources was incorporated on 17 July 2009 with the initial shareholders being Minotaur Exploration Ltd. and Platsearch NL, ASX-listed, exploration companies.
All TMZ exploration tenements lie within the Thomson Fold Belt, a region of deformed and intruded sediments and volcanics to the north of one of Australia’s premier metalliferous mining districts, the Lachlan Fold Belt. The belt has excellent exploration potential for large, high grade deposits, particularly Cobar-type.
In 2010, TMZ signed joint venture agreements with Compass Resources over a further 15 tenements in the Thomson Fold Belt and adjacent Lachlan Fold Belt. This gives TMZ a dominant position in a new mineral belt which has had minimal, but very encouraging, exploration so far.
