Australian gold and copper explorer Torrens Mining (ASX: TRN), presents 44 further rock chip samples systematically taken from the Goldie Prospect, part of the Company’s wholly-owned Mt Piper Gold Project in Central Victoria. The new results include high-grade gold (Au) assays from the first in-situ quartz reef samples collected from the base of historic workings.
The new rock chip results confirm high-grade gold reef mineralisation remains unmined at the Goldie Prospect, with the exceptional high-grade rock chips now reported over a minimum strike length of 120 m, and several parallel reefs identified within potentially a 150 m wide corridor.
In-situ reef sample results include:
- 31.08 g/t Au in RC047
- 16.97 g/t Au in RC049
- 11.38 g/t Au in RC048
- 7.94 g/t Au in RC050.
Significant new rock chip results include:
- 30.45 g/t Au in RC010
- 16.18 g/t Au in RC016
- 16.10 g/t Au in RC015
- 14.42 g/t Au in RC018
- 8.95 g/t Au in RC008
- 8.41 g/t Au in RC019
- 8.72 g/t Au in RC030
- 7.42 g/t Au in RC013.
The Goldie Prospect (previously named Crough’s Hill South) is marked by a pronounced gold-in-soil anomaly over 300m wide, generated during Torrens’ regional soil sampling campaign conducted earlier in 20211. These new assay results confirm anomalous gold mineralisation over a strike length of more than 300m that presently remains open at depth. The Goldie Prospect occurs to the immediate west of the boundary between the Cambrian-aged Heathcote Greenstone Belt and the Devonian-aged Pyalong Granodiorite. Historic workings over a strike length of ~600m have targeted near-surface quartz veins, with a concentration of historical workings over ~120 m corresponding to high-grade Au rock chip results.
In-field observations indicate that high gold grades are associated with stylolitic seams in quartz. Work to understand the association with pathfinder elements is ongoing: localised elevation in tungsten, arsenic and antimony reflects complex geochemical contributions from Cambrian sedimentary rocks, metabasaltic rocks and the Devonian I-type granite.
Continued systematic sampling and mapping are underway, with further results expected in Q1, 2022.
