Thomson Resources Limited (ASX:TMZ) has received strong tin results from recent drilling at its Bygoo project near the historical Ardlethan tin mine in central NSW.

Ten holes for 762 metres at Bygoo North returned best results of 10 metres at 0.6% tin from 24 metres, 12 metres at 0.5% from 17 metres and 2 metres at 1.9% from 38 metres.

Testing new zone

The drilling was designed to test a new shallow greisen zone that appeared to trend north-south through the historical Dumbrells Pit.

One hole continued through the shallow Dumbrells zone to intersect the east-west trending Main Greisen and returned 20 metres at 1.2% from 49 metres.

Strong tin results

Other strong Bygoo North results were 7 metres at 0.4% from 18 metres, 30 metres at 0.4% from 40 metres, 8 metres at 0.4% from 26 metres and 16 metres at 0.3% from 18 metres.

The drilling defined a wide corridor of mineralisation extending at least 200 metres around the historical pit, with the better intercepts under and to the north of the pit.

Diamond drilling planned

This zone is shallow and open to the north with further drilling planned in a bid to further extend the high-grade tin zones.

Diamond drilling will be utilised to test the northern extension of Dumbrells and the eastern extension of Main Zone, both of which are open.

Big Bygoo results

Another 15 holes for 1,036 metres were drilled in the Big Bygoo area, 2 kilometres south of Bygoo North, targeting extensive historical workings at four prospects.

Several promising intersections were returned including 3 metres at 1.0%, 3 metres at 1.2%, 24 metres at 0.6% and 4 metres at 1.4%.

The workings are scattered over the Ardlethan Granite outcrop over a 1-kilometre area, where initial drilling focused on a 100-metre long section of the Temora line.

This was Thomson’s first drilling program in the area and the company believes the intersections warrant follow-up.

Gold results pending

Results are also pending from the nearby Harry Smith gold prospect where nine holes were drilled for 833 metres.
