Tasman Resources Expands Drilling at Titan West and Parkinson Dam Projects
Tasman Resources (ASX:TAS) is gearing up for a significant ramp-up in drilling activity across its Lake Torrens and Parkinson Dam projects, with Fortescue (ASX:FMG) set to drill two maiden holes at the Titan West IOCG target starting late August 2026. Meanwhile, Tasman plans up to twenty new drill holes at Parkinson Dam targeting high-priority epithermal and hydrothermal prospects.
- Fortescue to drill two maiden holes at Titan West IOCG target
- Up to 20 new drill holes planned at Parkinson Dam project
- Parkinson Dam targets revised to 20 high-priority sites from 6
- Drilling timing hinges on rig availability and government approvals
- Historical drill hole PD63 returned significant gold and silver grades
Fortescue Advances Titan West Drilling Plans
Tasman Resources is set to see Fortescue Resources Pty Ltd, its joint venture partner, initiate two maiden drill holes at the Titan West target within the Lake Torrens IOCG project. These holes are scheduled to commence in late August 2026, subject to rig availability. Fortescue currently holds a 51% interest in the project, with the option to increase to 80% by sole funding up to $11 million in exploration.
The Titan West target, approximately 30 kilometres north of BHP’s Olympic Dam, remains largely untested since a single drill hole by Western Mining Corporation in 1981 failed to adequately assess its gravity and magnetic anomalies. The new drilling will leverage recent Magnetotelluric (MT) data indicating a deep conductive body extending potentially 2-3 kilometres beneath the surface, a signature consistent with IOCG mineralisation.
Expanded Drilling Campaign at Parkinson Dam
At Parkinson Dam, Tasman Resources plans a substantial escalation from earlier programs, targeting up to twenty drill holes focused on newly identified hydrothermal and epithermal targets. This represents a shift from the six earlier targets identified since 2024, following a detailed review by Archimedes Consulting and geologist Tony Belperio.
The new target list was developed using two years of fresh geophysical data combined with extensive historical drilling information, including 81 holes drilled between 2006 and 2009. Notably, drill hole PD63 previously intersected high-grade mineralisation with 21 grams per tonne (g/t) gold over 21 metres and silver grades reaching 83 g/t over the same interval, underscoring the project's potential.
Operational and Regulatory Factors Impacting Drilling
Both drilling campaigns face timing uncertainties, contingent on the availability of drilling rigs and South Australian Government approvals, particularly for the Parkinson Dam program. Fortescue’s management of the Lake Torrens joint venture includes navigating these logistical and regulatory hurdles while progressing the Titan West drilling.
Tasman’s Executive Chairman Greg Solomon emphasised the strategic importance of these campaigns, highlighting the combination of advanced geophysical modelling and historical data as a strong foundation for exploration success. The company’s approach reflects a measured expansion targeting high-value mineralisation zones in a region with proven IOCG and epithermal systems.
Bottom Line?
Tasman’s upcoming drilling programs mark a decisive step in unlocking the potential of two promising South Australian projects, but timing and approvals remain key variables to watch.
Questions in the middle?
- Will Fortescue increase its Lake Torrens stake beyond 51% after these drill results?
- How will government approvals shape the timing and scale of Parkinson Dam drilling?
- Can the new high-priority targets at Parkinson Dam deliver mineralisation comparable to historic high-grade intersections?
