Climbing the tin-copper-silver ladder: Thomson is already sampling for extensions to Conrad mineralisation

Thomson is taking the next step in exploring the Conrad silver-tin-lead-copper deposit with geological mapping and rock chip sampling to test for extensions of known mineralisation.
The mapping and rock chip sampling at the 7.5km long polymetallic lode system will focus on the 4km long lode segments to the southeast of the current JORC resource where historic sampling and shallow drilling place the Conrad lode as tin-copper-silver dominated and significantly underexplored.
Thomson Resources (ASX:TMZ) expects the mapping and sampling programs to provide integral data for planning of follow up geophysics and drilling set for 1H22.
Conrad currently hosts an Indicated and Inferred resource of 20.7Moz of silver equivalent for a 2.2km long segment at the northwest end of the lode.
Executive chairman David Williams says the company is mobilising at several focus areas and accumulating further data on TMZ’s already highly informed take on the most prospective areas in its New England Fold Belt projects.
“The work initiated at Texas and here at Conrad are important precursors to refining our targeting of potentially expansional and extensional areas,” he added.
The Conrad silver-tin-lead-copper polymetallic lode deposit is a key project within the company’s New England Fold Belt Hub and Spoke silver strategy near the town of Inverell, New South Wales.
Historical rock chip sampling in the area of focus totals just 88 samples, some of which were taken from a series of pits and shafts dating back to the 1900’s.
These returned results of up to 1.9% tin, 3.1% copper, 1.4% lead and 439 grams per tonne silver.
Thomson’s rock chip sampling is intended to deliver higher density rock chip coverage of the exposed lode system.
Shallow historical drilling has intermittently tested a 1.5 km strike length of the 4km lode segment, returning anomalous tin, silver and copper intersections.
However, follow-up drilling on these results is yet to kick off, despite analysis showing the historical intersections compare favourably to drill intersections seen on outer margins and shoot tops in the Conrad Resource area.
It all suggests that deeper drilling is warranted in the southeast Lode area to explore for undiscovered shoots which may lie at depth below these historic drillhole intercepts.
