Thomson Resources Begins Drilling at Historic Silver Spur Deposit for Base Metals Project in Texas
Thomson Resources (ASX: TMZ) has begun a first drilling campaign at the historic high-grade Silver Spur mine as part of its 100% Texas-owned silver-based metals project in southeast Queensland. .
The program will include up to 2000 meters of diamond coring and reverse circulation drilling, testing extensions at depth and towards the current resource and near-resource exploration targets.
It follows the May completion of an extensive dipole-dipole induced polarization (DDIP) survey in Texas, highlighting seven district-wide clusters of strongly anomalous chargeability anomalies that have not been previously drill tested.
Silver Spur’s target group is centered on the historic mine of the same name, where mineralization is closely associated with the northwest trending Stokes Fault linking Silver Spur to the nearby Twin Hills deposit.
The drilling will be carried out by Thomson shareholder, Australian Mineral & Waterwell Drilling, using the same versatile rig that recently completed exploration at Thomson’s wholly-owned Lachlan Fold Belt projects in New Wales. from South.
Preparation of the bottom
Executive Chairman David Williams said drilling at Silver Spur was preceded by lengthy background preparation.
“This is the culmination of extensive work by our geological consultants and technical team in developing mineral resource estimates for the Texas deposits,” he said. .
“The result of the geophysical surveys and geological studies has unlocked the significant exploration potential of this area and we look forward to releasing the results.”
Structurally controlled deposit
Silver Spur is a structure-controlled silver-based metals deposit located 2 kilometers southeast of the Twin Hills open pit mine.
The deposits were mined between 1892 and 1925 from high-grade shoots and halo mineralization, with Silver Spur producing approximately 100,000 tonnes of ore from a high-grade core of the deposit containing 2.19 million ounces of ore. silver (at an average grade of 800 grams per tonne), 690 t of zinc, 1050 t of lead and 990 t of copper and a by-product of gold.
Current Mineral Resource estimates for the Texas deposits contain a total of 660,000 t at 54 g/t silver, 2.03% zinc, 0.69% lead and 0.09% copper grading 156 g/t and contained 3.3 Moz (both silver equivalents).
