Thomson Resources advised that further strong mineralised greisens have been intersected in recent drilling at the Thomson's 100% owned Bygoo Tin Project, located in the Lachlan Fold Belt in New South Wales. Results have now been received for two more batches of assays from the 2022 drilling program, including four holes drilled at the new discovery at "Stewarts", 300m NW of the Main Zone. The holes were following up an intersection of 111m at 0.45% Sn from 57m depth in BNRC691.

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. As it turns out this is partly true, but instead of the mineralisation being 10-15m wide it is variable and up to 60m wide. The observed greisens are variable in strength and mineralogy, varying from quartz-tourmaline to quartz-topaz.

Within the overall "greisen" zone there are patches of unmineralised granite between stronger greisen development. There is one final batch of assays that is still in the laboratories for assay. Results are expected in late July or August.

The zone itself appears to be thickest and strongest next to the Ardlethan granite boundary. Holes drilled under the shallow workings in the granite outcrop area returned weak intercepts of poorly developed thin greisens. Heading northeast the zone is open, although it is partly constrained by the barren hole BNRC81.

Further drilling is needed to extend the zone to the northeast. BNRC80D was drilled as a diamond hole partly due to weather and logistics. The hole was designed to stay in the greisen and collect information on the geology and geometry of the mineralisation.

It intersected 69.5m at 0.5% Sn from 60m including 2.5m at 2.1% Sn from 70.6m and 7m at 1.7% Sn from 98.4m. One individual 60cm sample at 100.5m depth assayed at 10.1% tin. That sample had 0.84% copper as well and an interval of 4.7m from 100m ran 0.25% Cu (no other significant elements).

BNRC82 found a broad intercept of 36m, which featured four separate 3-5m widths of well mineralised greisen: 3m at 0.6% Sn from 100m; 3m at 0.5% Sn from 114m; 5m at 0.6% Sn from 121m and 3m at 0.4% Sn from 133m. These were separated by barren intervals of less altered granite, suggesting that the mineralisation is "feathering" and weakening towards the north. BNRC83 was another hole, like BNRC78, to test the width of the greisen and was successful with 31m at 0.4% Sn from 120m.

BNRC84D was a diamond core hole drilled primarily to assist Mineral Resource Estimation. It was designed as a twin hole of BNRC013 which intercepted 46m at 0.8% Sn from 88m depth. The precollar deviated strongly, so the full length of the RC intercept was not "twinned": but a 36m wide greisen was intersected from 69m depth.

Within this was a high-grade interval of 7m at 1.7% Sn from 98.4m. One further batch of assays remain outstanding for the last three holes drilled in the truncated autumn 2022 drilling program. Positive results from nine of the ten holes drilled so far indicate that there remains a significant program of drilling for mineralisation extensions to be carried out in summer 2022-23.
