Special Report: Thomson now has more room to grow its Harry Smith gold project after acquiring a 71sqkm exploration licence with a historical gold and antimony working.

The new Barellan tenement is about 20km northwest of Harry Smith and has similar host rocks.

It contains the Warrawong prospect, a 1km long anomaly with one small, shallow historical hard rock gold and antimony working that has been the focus of exploration by the vendors.

Thomson Resources (ASX:TMZ) believes that the tenement is very much underexplored and intends to apply what it has learned at Harry Smith to better understand its potential.

The company has also lodged a licence application for the land between Harry Smith and the Barellan tenement, taking its total land holding in New South Wales’ Lachlan Fold Belt up to just over 2,360sqkm.

Barellan gold potential

The Warrawong prospect within the Barellan tenement was (re)discovered in the 1980s after an 18-metre wide exposure of iron-stained quartz-vein stockwork in metasediments was uncovered by a farmer in a crop paddock drainage channel.

An initial rock chip sample traverse along the channel defined a zone averaging 18m at 2.5 grams per tonne gold and 1 per cent antimony.

Subsequent channel rock sampling and shallow auger drilling by Carpentaria Resources in 2014 defined a 200m by 30m bedrock gold anomaly that remains open to the southeast.

This included a contour drain at its centre that returned 60m at 1.5g/t gold in historical work with resampling where possible returning a result of 32m at 0.5g/t gold while a top result of 1m at 8.8g/t gold confirmed the presence of high-grade mineralisation.However, the entire channel was not able to be systematically sampled.
