Thomson Resources (ASX: TMZ) reports that it has extended the recent Stewart tin discovery at its Bygoo Project in New South Wales following the intersection of ‘strong’ greisens.
The results come from a 13-hole RC drill program, with the company noting that the Stewarts greisen now measures more than 50m in thickness at its widest point.
Additional extensions were also encountered at the Dumbrells, Smiths and P380 greisens, with assay results pending.
Speaking on the news, Executive Chairman David Williams said: “This has been a difficult season for drilling at the Lachlan Fold Belt projects, but the teams have persisted and managed to complete a good program at the Bygoo tin project. This should now give us sufficient data to complete the maiden Mineral Resource Estimate for the Bygoo tin deposit which was our aim.
“This should now give us sufficient data to complete the maiden Mineral Resource Estimate for the Bygoo tin deposit”
That aside, we continue to see the mineralised zones extending when we drill and continues to show what a great tin project Bygoo is.
We look forward to being able to share the assay results once they become available.”
The 1,870m program was tasked with extending and delineating Stewarts 300m northwest of the Main Zone, and was guided based on an earlier intersection of 118m @ 0.43% Sn from 57m (BNRC69).
Holes were drilled at various angles and orientations to gain a better understanding of geometry, with Thomson reporting ‘wide’ greisen intersections of a similar mineralogy to BNRC69 including 75m in BNRC75; 113m in BNRC78; 60m in BNRC79; 79m in BNRC80D; 66m in BNRC82 and 80m in BNRC83.
Delays were encountered due to intermittent weather, farming activities, supply chain issues and COVID, with all zones remaining open for further activity during the next drilling season.
In addition, a pair of diamond holes were completed to gather further data ahead of a planned maiden JORC 201 Mineral Resource Estimate for Bygoo later in 2022.
Due to the commencement of farming operations, drilling has moved from Bygoo to Thomson’s Yalgogrin Gold Project, with next assay results expected in May.
