Thomson Resources (ASX: TMZ) has commenced an initial RC and DD programme at the historic high-grade Silver Spur mine located at the 100% Thomson owned Texas silver-base metal project in southeast Queensland, Australia.
Thomson recently completed a large DDIP survey at Texas, highlighting seven clusters of strongly anomalous chargeability anomalies that have not been previously drill tested.
The Silver Spur Target cluster is centred on the historic Silver Spur mine where mineralisation is closely associated with the northwest trending Stokes Fault that links Silver Spur to the Twin Hills deposit.
The Silver Spur drilling programme will target extensions to the current Silver Spur resource as well as compelling near resource exploration targets.
The drill programme will be conducted by Thomson’s shareholder, Australian Mineral & Waterwell Drilling (AMWD), using the same multi-purpose rig that recently completed a drilling programme for Thomson on the company’s 100% owned Lachlan Fold Belt projects in NSW.
It is exciting to be drilling our own holes at the New England Fold Belt Hub and Spoke projects with the commencement of drilling at the Texas Project,” Executive Chairman, David Williams, said.
“This initial drill programme will be testing high-priority targets at the Silver Spur deposit.
“This is the culmination of extensive work conducted by Thomson Resources and its geological consultants and technical team as part of developing Thomson’s Mineral Resource Estimates for the Texas deposits and the outcome of the geophysical surveys and geological studies it has undertaken to unlock the significant exploration potential of the area.
“We look forward to reporting the results from this initial drill programme over the coming weeks and months.”
Texas District Resource and Silver Spur Deposit
Over the past 12 months Thomson has reported Indicated and Inferred Mineral Resource Estimates (MRE’s) at a 25 g/t AgEq cutoff for the Texas district deposits (Silver Spur, Twin Hills and Mt Gunyan) totalling a combined 19.5 Moz AgEq. This is part of the larger combined Tablelands and Mt Carrington polymetallic resource base controlled by Thomson that currently totals 22.8 Mt at 119 g/t AgEq for a total resource base of 87.1 Moz of AgEq for MRE’s published by Thomson.
Silver Spur is a structurally controlled higher-grade silver-base metal deposit located two km southeast of the Twin Hills open pit. The deposits were mined between 1892 and 1925 that and are characterised by high-grade shoots and halo mineralisation that defines the current Thomson Silver Spur MRE.
The historic Silver Spur mine produced approximately 100 Kt ore from a high-grade core of the deposit containing 2.19 Moz silver (average grade of 800 g/t Ag), and 690 t of zinc, 1,050 t of lead and 990 t of copper and by-product gold.
The current Thomson MRE’s for the Texas deposits contain in aggregate 660 Kt at 54 g/t Ag, 2.03% Zn, 0.69% Pb and 0.09% Cu for a AgEq grade of 156 g/t and contained 3.3 Moz AgEq.
