(MENAFN- ABN Newswire)
Thomson Resources Ltd (ASX:TMZ) has discovered gold systems in NW NSW and picked up projects with copper potential near Byrock and Mudgee. A recent VTEM survey has picked has picked up strong conductive anomalies in each of the latter two indicating copper potential. Many of the projects also have tin potential e.g. the Mt Jacob area near Kempsey which is primarily a gold play.
The Mt Jacob Intrusion Related Gold System is a 3km thermal anomaly (growth of the mineral biotite) and encloses a semicircular magnetic anomaly (growth of the iron sulphide mineral pyrrhotite) and a 1km long surface gold anomaly in soil and rock. Scattered around that are tin and copper skarns. All of the above are thought to relate to an as yet unseen granitic intrusion which has potential to host an intrusion-Related Gold deposit.
There are two mineralised horizons - the tin-copper skarn at Basin one and below that a gold bearing conglomerate.
A drill section through the Basin One tin-copper skarn showing proposed holes to take the deposit to JORC status. Currently Thomson has declared an exploration target for the occurrence. This is 1.8 to 4.9 million tonnes with grades of between 0.1%-0.2% Sn and 0.25%-0.5% Cu (between 1800 and 10000 tonnes of tin and between 4500 and 24000 tonnes of copper).
The Wilgaroon area.
Straits Resources drilled in 1996 and intersected sedimentary rocks intruded by small porphyries and veins with 250m of tin-tungsten alteration including best assays of 2.5% Sn 1.42% W 0.1% Cu and 0.2g/t Au. The average assays from 250 to 500m depth were highly anomalous - 338ppm Sn and 197 ppm W.
