Outstanding Results in Second Round of Drilling at Bygoo Tin
Perth, Oct 21, 2015 AEST (ABN Newswire) - Thomson Resources Ltd (
ASX:TMZ) is pleased to announce drilling results from its second round of drilling at the Bygoo tin project near the Ardlethan tin mine, NSW. Five RC holes for 600m were drilled to test the newly discovered tin-bearing greisen from the first round of drilling completed in July.
Highlights:
- Exceptional intercept of 35m at 2.1% Sn from 44m depth
- "Hidden" greisen zone extended and remodelled: open to east and down dip
- Greisens occur as multiple discrete steeply-dipping zones
Exceptional, high grade tin intersections were recorded in holes that penetrated two of the three greisen zones that have now been defined by drilling (shown in Figures 1 and 2, see link below). The standout intersections are as follows:-
- BNRC011 - 35m @ 2.1% Sn from 44m including 6m @ 3.1% Sn from 56m, 5m @ 6.0% Sn from 66m, and 4m @ 3.8% Sn from 75m (all in the "hidden" Greisen A)
- BNRC013 - 6m @ 0.8% Sn from 67m, 11m @ 1.4% Sn from 88m, and 10m @ 2.0% Sn
from 108m (all in Greisen B)
The thick, high grade intersection recorded in hole BNRC011 is located with the "hidden" greisen, here termed Greisen A, which was first identified in BNRC010 (13m at 1.0% Sn - located 25m to the west) from the original drill program as reported to the ASX on 13 July 2015. The greisen is now interpreted to dip steeply north and sits in the footwall to the main greisen (Greisen B) that was intersected in hole BNRC0013. Modelling work indicates that the BNRC011 intersection is between 8-15m in true thickness.
The BNRC011 intersection contains some impressive grades, with individual metres up to 11.1% Sn. The length of the intersection has provided some good detail on the tin distribution and also shows that deleterious elements are very low or undetectable. This is a consequence of the "clean" occurrence of coarse cassiterite in quartz and feldspar with very little of the sulphide mineralisation that often occurs with tin elsewhere.
A further drill program will define and extend the greisens, drilling from north to south. This program should underpin modelling to provide a JORC compliant resource and is planned to take place before the end of the year.
