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 second hole in the drill programme (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 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.
“It is encouraging that mineralisation has been intersected in this early hole in our Silver Spur exploration programme,” Executive Chairman, David Williams, said.
“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 drilling programme at Silver Spur was commenced in mid-June 2022 and was designed to target extensions to the current Mineral Resource as well as compelling near resource exploration targets.
A programme of resource expansion holes has been designed to test for extensions of the high-grade mineralisation outlined by the Thomson block model and drill hole data base for the deposit, that suggests the higher-grade silver–base metal mineralisation remains open along strike and at depth.
The recent dipole-dipole induced polarisation (DDIP) survey shows a strong chargeability anomaly enveloping and extending beyond the resource and along strike of the controlling Stokes Fault system.
Additionally, undrilled down-hole electromagnetic (DHEM) anomaly from a 2011 survey by Alcyone Minerals further supports the DDIP anomaly suggesting the potential for the Silver Spur mineralisation to extend to depth beneath the known resource.
