The drilling will initially target Thomson's two high-grade tin discoveries at the Bygoo North and Bygoo South prospects 10 kilometres north of the former Ardlethan tin mine in central NSW.
Other tin prospects which have had no modern exploration are also being considered for testing.
The program will take about two weeks and results should be available in September.
Bygoo Tin Project
The Bygoo Tin Project was acquired by Thomson Resources in 2015 and lies on the 100% owned EL 8260. The EL surrounds the major tin deposit at Ardlethan which was mined until 1986, with over 31,500 tonnes of tin being produced (reference Paterson, R.G., 1990, Ardlethan tin deposits in the Australasian Institute of Mining and Metallurgy Monograph no. 14, pages 1357-1364). There are several early-twentieth century shallow tin workings scattered up to 10km north and south of Ardlethan, and few have been tested with modern exploration. Thomson has had immediate success in drilling near two of the historic workings, Bygoo North and South, which lie towards the northern end of the tin-bearing Ardlethan Granite.
At Bygoo North Thomson has intersected multiple high-grade tin intersections in a quartztopaz- cassiterite greisen including 11m at 1.0% Sn (BNRC10), 35m at 2.1% Sn (BNRC11), 11m at 1.4% Sn (BNRC13), 11m at 2.1% Sn (BNRC20) and 29m at 1.0% Sn (BNRC33). The greisen appears to be steep to vertical; about 5-10m wide in true width; strike east-west; and the tin intersections appear to have continuity within the greisen.
At Bygoo South Thomson has intersected a sulphide-rich quartz topaz greisen with highgrade tin intersections including 8m at 1.3% Sn (BNRC21) and 20m at 0.9% Sn (BNRC31). The orientation and geometry of this greisen is not yet clear.
