OUTSTANDING TIN RESULTS FROM DRILLING AT
NEW BYGOO TIN DISCOVERY
HIGHLIGHTS
- The 2022 drilling program at the 100% owned Bygoo Tin Project in the Lachlan Fold Belt of New South Wales has extended the "Stewarts" discovery made in 2021
- First of 4 batches of assays received
- The "Stewarts" tin greisen returned intercepts of:
- BNRC75 - 17m at 0.9% Sn from 129m depth o BNRC78 - 23m at 1.0% Sn from 62m depth o BNRC79 - 13m at 0.4% Sn from 45m depth
- Gold results received from Yalgogrin drilling indicate large low grade gold system in addition to the high-gradelodes
- Wet weather and farming operations ended both programs before they could be completed
Thomson Resources (ASX: TMZ) (OTCQB: TMZRF) (Thomson or the Company) advises 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 the first batch of assays covering the first 5 holes 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.
Wide tin intercepts were made of similar tenor to the intersection in BNRC69, such as 17m at 0.9% Sn from 129m depth in BNRC75; 23m at 1.0% Sn from 62m depth and 39m at 0.4% Sn from 89m depth in BNRC78; 13m at 0.4% Sn from 45m depth in BNRC79; (see Table 2 and Figure 2). Holes were drilled at different angles and orientations to better understand the geometry.
Three further batches of assays are still in the laboratories for assay. Results expected in late June or July.
Executive Chairman David Williams commented:
"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.
"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."

Figure 2: Drill plan at the "Stewarts" zone.
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.
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 (Figure 2). Heading northeast the zone is open, although it is partly constrained by the barren hole BNRC81 (Figures 1 and 2). Further drilling is needed to extend the zone to the northeast.

Figure 3 shows a section including the discovery hole BNRC069. Follow up holes 78, 79, 82 and 83 show that the overall greisen is at least 50m wide with mineralisation in several zones of 20m wide or more.

personal | Table 2: Significant Intercepts at Bygoo, March 2022 | |||
Hole | INTERCEPTS | Description | ||
BNRC075 | 4m at 0.9% Sn from 80m | The first hole testing a "down-dip" scenario for the | ||
and | discovery hole (BNRC69), drilling to the NW, intersected a | |||
4m at 0.7% Sn from 112m | wide greisen. The greisen was variable with alternating | |||
also | mineralised greisens and barren granite intervals, but | |||
17m at 0.9% Sn from 129m | gained strength with depth. | |||
BNRC076 | 2m at 0.3% Sn from 45m | The first of two holes testing shallow workings, 60m west | ||
of the discovery hole. Only a weak greisen was | ||||
intersected, directly below some shallow workings. | ||||
BNRC077 | 2m at 0.2% Sn from 54m | Another hole under the deepest old working intersected | ||
a tourmaline greisen directly below the main working, | ||||
with weak tin | ||||
BNRC078 | 23m at 1.0% Sn from 62m | This hole returned to the discovery hole area and was | ||
For | and | drilled to the NW like BNRC75, but collared 40m to the | ||
39m at 0.4% Sn from 89m | SW. The hole intersected a 66m wide greisen which was | |||
stronger at shallower depths. | ||||
BNRC079 | 13m at 0.4% Sn from 45m | As BNRC78 had not fully defined the greisen extent | ||
And | another hole was drilled 30m forward. This intersected a | |||
3m at 0.5% Sn from 74m | narrower, weaker greisen from a deeper depth. | |||
BNRC080D | 10m at 0.3% Sn from 31m | This hole was primarily drilled to return drill core to help | ||
And | with resource estimation - mineralogy, density and | |||
9m at 0.3% Sn from 51m | orientations. These results are from the RC precollar | |||
only, assays are awaited for the core portion of the holes. | ||||
BNRC81-87 | Assays awaited - 3 batches, 2 RC and one diamond core. |
