Junior explorer Thomson Resources (ASX: TMZ) has intersected further strong mineralised greisens in drilling at its wholly-owned Bygoo tin project in New South Wales’ Lachlan Fold Belt.
The first five holes completed at the Stewarts discovery, 300 metres northwest of the Main Zone, were designed to follow-up an earlier intersection of 111m at 0.45% tin from 57m depth.
Wide intercepts were reported of similar tenor to that intersection, and included 17m at 0.9% tin from 129m; 23m at 1% tin from 62m; 39m at 0.4% tin from 89m; and 13m at 0.4% tin from 45m.
Holes were drilled at different angles and orientations to better understand the Stewarts geometry.
The new assays follow positive tin results from drilling at Stewarts in April.
A drilling campaign at the Yalgogrin gold project, also in the Lachlan Fold Belt, aimed to extend the Bursted Boulder and Shellys occurrences but was terminated after four holes due to continued rain.
Maiden drilling by Thomson in mid-2020 intersected the first known high-grade gold results at these targets, with a best assay below the Bursted Boulder shafts and pits of 5m at 10.3 grams per tonne gold, and at Shelleys of 2m at 7.5g/t gold.
Two holes in the terminated program targeted an extension of the Shellys lode to the west and hit low-level gold at expected depths, including 18m at 0.3g/t.
Both intersected shallow, wide zones south of Shellys, believed to be indicative of a new and unexplored gold zone which is open to the west and could extend further south.
A third hole struck the projected Bursted Boulder lode 40m east of its last intersection, but was weak at this point with an assay of 1m at 1g/t gold.
It remains open to the east and west where planned holes to follow up a previous hit of 3m at 6.9g/t gold could not be drilled.
Executive chairman David Williams said the results validated the prospectivity of the “largely-untapped” Lachlan Fold Belt.
“While this has been a challenging drill program with weather delays and the length of time it is taking to get assays [from the lab], the first batch of results demonstrates the quality of the Bygoo project,” he said.
“The Yalgogrin results are not as strong as previous programs [but they] do show that there are quality gold targets in this portfolio of tenements to add to the strong tin results from Bygoo.”
