Further strong mineralised greisens intersected by Thomson have extended the Stewarts discovery within its Bygoo Tin Project in New South Wales’ Lachlan Fold Belt.

Notable results from the first of four batches of assays are 23m at 1% tin from a down-hole depth of 62m (BNRC78) and 17m at 0.9% tin from 129m (BNRC75).

The holes were drilled to follow-up on an intersection of 111m at 0.45% tin from 57m at BNRC69 with Thomson Resources (ASX:TMZ) noting that the new, wide tin intercepts had a similar tenor to the previous hole.

Meanwhile, drilling at the Yalgogrin Gold Project has indicated the potential for a large, low-grade gold system in addition to the high-grade lodes.

Operations at both projects were ended early by wet weather and farming operations.

“Whilst this has been a challenging drill program at Bygoo Tin Project, with weather delays and the length of time it is taking to get assay results, the first batch of results again demonstrates the quality of the Bygoo Tin Project,” executive chairman David Williams notes.

“The Yalgogrin results, whilst not as strong as previous programs, do show that there are quality gold targets in this portfolio of tenements to add to the strong tin results from Bygoo.

“The Lachlan Fold Belt project is still largely untapped with a number of both tin and gold areas still to be drilled by Thomson.”

Lachlan Fold Belt drilling

The drilling at Stewarts was initially aimed at defining the width of the zone as it was thought that the discovery hole, BNRC69, may have drilled down dip.

While this has been found to be partially true, the mineralisation was found to be variable and up to 60m wide rather than being 10m to 15m wide.

Notably, the zone itself appears to be thickest and strongest next to the Ardlethan granite boundary.

Thomson adds that the zone remains open to the northeast though further drilling is needed to extend it further in this direction due to the partial constraint caused by the barren hole BNRC81.

Over at Yalgogrin, drilling sought to extend the Bursted Boulder and Shelly occurrences but only four holes were drilled to the onset of continued rain.

Holes TGRC19 and 21 targeted an extension of the Shellys lode to the west and both hit low level gold at the expected depths.

However, they also intersected shallow, wide gold zones south of Shellys, possibly indicating a new previously unknown and unworked gold zone.
