VTEM Survey Identifies 32 EM Anomalies Over 47km² at Odyssey’s Tuckanarra Project
Odyssey Gold’s recent 47km² airborne VTEM survey at Tuckanarra has identified 32 priority electromagnetic anomalies linked to gold mineralisation, revealing promising new exploration targets under cover. The survey confirms EM techniques as a powerful tool for expanding known resources in the prolific Murchison Goldfields.
- 47km² VTEM airborne electromagnetic survey completed at Tuckanarra
- 32 priority EM anomalies identified and scored for follow-up
- Six initial targets modelled as advanced conductors for immediate drilling
- New anomalies coincide with known gold sulphide mineralisation and extend under cover
- Future work includes fixed loop EM surveys, RC drilling, and mining technical studies
Comprehensive Airborne Survey Unlocks New Targets
Odyssey Gold (ASX: ODY) has announced the successful completion of a 47 square kilometre helicopter-borne Versatile Time-Domain Electromagnetic (VTEM) survey over its Tuckanarra Gold JV Project in Western Australia’s Murchison Goldfields. The survey, flown by UTS Geophysics and interpreted by Southern Geoscience Consultants (SGC), identified 32 electromagnetic (EM) anomalies that are spatially associated with known gold mineralisation.
This extensive geophysical effort confirms the effectiveness of airborne EM methods in detecting sulphide mineralisation, which is closely linked to gold deposits in the region. Notably, all known gold resources within the survey area were coincident with EM anomalies, validating the survey’s targeting capability.
Prioritising Targets for Immediate Follow-Up
Odyssey’s geologists applied empirical and conceptual criteria to score and prioritise the 32 anomalies, narrowing down to six advanced conductors that represent immediate drill targets. These targets occupy diverse structural and stratigraphic positions, reflecting the complex geology of the Tuckanarra greenstone belt.
Several anomalies lie beneath shallow cover with no prior soil sampling or drilling, highlighting the survey’s role in uncovering previously hidden exploration opportunities. The company plans to conduct fixed loop EM surveys to better define these conductors before initiating reverse circulation (RC) drilling programs.
Historical Data Supports Exploration Upside
Historical drilling and geophysical data from targets such as Pluto, Vivo, Boyd’s West, and Judy’s East provide encouraging context. For example, previous rotary air blast (RAB) drilling at Pluto intersected significant gold grades, while the Vivo target showed anomalous gold in oxide horizons. The new EM anomalies align with these historic results, suggesting potential extensions of high-grade mineralisation.
Odyssey’s Director Matt Syme emphasised the transformative impact of the survey, stating that the airborne EM results are “game changing” for the project’s exploration strategy. The technique offers a cost-effective and efficient means to grow and extend shallow oxide resources to depth.
Strategic Next Steps and Project Outlook
Looking ahead, Odyssey plans a suite of follow-up activities including technical studies on mining options for existing resources, detailed ground EM surveys, and targeted RC drilling of priority conductors. The company also aims to extend the high-grade underground resource at the Highway Zone and test the Bollard North conductor.
The Tuckanarra Project currently hosts an indicated and inferred gold resource of approximately 407,000 ounces at an average grade of 2.5 g/t Au, situated within a prolific gold district with a rich mining history. Odyssey’s systematic approach combining modern geophysics with historical data positions the project well for resource growth and value creation.
Bottom Line?
Odyssey Gold’s VTEM survey has opened a new chapter in Tuckanarra exploration, setting the stage for drilling campaigns that could redefine the project’s resource potential.
Questions in the middle?
- Which of the 32 EM anomalies will yield economically viable gold mineralisation upon drilling?
- How will the upcoming technical mining studies influence development timelines and capital allocation?
- Can Odyssey replicate the success of known deposits by extending mineralisation at depth using EM targeting?
