Thomson Resources intersects zinc-lead-copper-silver mineralisation at Silver Spur

Thomson Resources (ASX:TMZ) has intersected zinc-lead-copper-silver mineralisation at the historic ‘high-grade’ Silver Spur mine located at the 100% owned Texas silver-base metal project in southeast Queensland.

The company reports that the second hole in the drill program (TX002RCD) was drilled on the northern margin of the Silver Spur mine to test a Dipole-Dipole Induced Polarisation (DDIP) chargeability anomaly, and an interpreted strike extension of the resource associated with the Stokes Fault.

The company announces that the hole intersected a broad zone of quartz veining and alteration with multiple veins of up to 5cm of base metal sulphide and silver mineralisation.

The dominant sulphide is brown sphalerite (zinc sulphide) with silver grey galena (lead sulphide) and minor yellow pyrite-chalcopyrite (iron/copper sulphide).

Scans with a handheld pXRF indicate the vein also contains elevated silver.

The drilling program at Silver Spur started in mid-June 2022 and was designed to target extensions to the current Mineral Resource, as well as compelling near resource exploration targets.

Commenting on the results, Executive Chairman David Williams noted: “It is encouraging that mineralisation has been intersected in this early hole in our Silver Spur exploration program.

The mineralisation is over a broad interval and is located in a new position that  has not been tested previously highlighting the exploration potential at Silver Spur and the broader Texas area.

The program has been a bit disjointed due to the land where the holes were planned still being extremely saturated from the ongoing unprecedented rain events. We have had to drill those planned holes where we could safely bring the drilling rig, which has severely curtailed our program.

Nevertheless, to see this sort of result from one of our first holes in the New England Fold Belt Hub and Spoke Strategy is a great outcome.”

The quartz veining, base metal mineralisation and associated silicification is interpreted to extend west beyond the footwall of the Stokes Fault System that controls the mineralisation at both the Silver Spur mine and Twin Hills mine to the north.

The mineralisation is outside the domains used for the previous Mineral Resource Estimate (MRE) at Silver Spur and could represent a new zone.

Previous drilling did not test this western position. By comparison, mineralisation was less than expected in the modelled lode positions.

A program of resource expansion holes has been designed to test for extensions of the ‘high grade’ mineralisation outlined by the Thomson block model and drillhole data base for the deposit, that suggests the ‘higher grade’ silver–base metal mineralisation remains open along strike and at depth.

Thomson Resources holds a diverse portfolio of minerals tenements across gold, silver, and tin in New South Wales and Queensland. The company’s primary focus is its aggressive “New England Fold Belt Hub and Spoke” consolidation strategy in NSW and Qld border region.
