iTech Minerals’ latest drone magnetic survey at Reynolds Range reveals extensive east-west gold and antimony-bearing structures, dramatically expanding exploration potential beyond previous models. The company plans targeted soil sampling and accelerated drilling to capitalise on these findings.
- New 25m spaced drone magnetic survey identifies multiple gold-antimony structures
- Prospective mineralised strike length increased from 2.5km to over 13km
- East-west structural controls replace previous NW-SE Lander Shear Zone model
- Structures align with magnetic dolerite dyke margins, guiding exploration
- Planned soil sampling and fast-tracked drilling to target expanded zones
Revolutionising Structural Understanding at Reynolds Range
iTech Minerals Ltd has unveiled a game-changing update from its Reynolds Range project in the Northern Territory. A newly completed ultra-detailed drone magnetic survey, flown at 25-metre line spacing, has exposed a network of gold and antimony-bearing structures far more extensive than previously recognised. This contrasts sharply with historical magnetic data spaced at 100 metres, which had painted a less detailed and arguably misleading picture of the mineralisation controls.
Where earlier exploration focused on a dominant northwest-southeast structural trend linked to the Lander Shear Zone, the new data reveals at least four significant east-west trending structures stretching over 13 kilometres. These structures, including the Sabre, Falchion, Lander, and Harpe zones, are closely associated with magnetic dolerite dykes intruded into pelitic schist – a geological setting conducive to hosting high-grade gold and antimony mineralisation.
Implications for Exploration Strategy
The discovery of these east-west structures fundamentally shifts the exploration paradigm at Reynolds Range. Historical drilling, often oriented to intersect the NW-SE Lander Shear Zone, may have missed or inadequately tested these newly identified controls. By mapping the magnetic signatures of dolerite dykes and their margins, iTech can now target mineralised shear zones with greater precision and efficiency.
Managing Director Michael Schwarz emphasised the leap in data quality and interpretative clarity, "The difference between the historic 100m spaced data and new 25m spaced data is like night and day. For the first time, the controlling structures that host high-grade gold and antimony mineralisation can be clearly seen. Importantly, these structures are much more numerous and extensive than previously thought, significantly increasing the potential for finding additional mineralisation."
Next Steps, Soil Sampling and Drilling Acceleration
Building on these insights, iTech plans a focused soil sampling program along the newly delineated east-west structures in the coming months. This targeted approach promises to reduce the scope and cost of sampling by concentrating on the most prospective zones rather than broad, indiscriminate coverage.
Simultaneously, the company is pursuing fast-tracked environmental and heritage clearances to expedite follow-up drilling. The upcoming drill campaign, potentially comprising 40 to 80 reverse circulation and diamond holes, will primarily revisit the Sabre and Falchion prospects but may also test new targets emerging from soil sampling results.
Strategic Context and Partnership
The Reynolds Range project, wholly owned by iTech Minerals, covers a substantial 791 square kilometres within the Aileron Province, a region known for its Paleoproterozoic mineralisation potential. The project benefits from a joint venture with SQM International Pty Ltd, which holds an option to earn up to 70% of lithium rights, while iTech retains full rights to gold and antimony.
This latest structural breakthrough enhances the value proposition of Reynolds Range by expanding the known mineralised footprint and refining exploration targeting. It also underscores the importance of modern geophysical techniques in unlocking complex mineral systems that historical methods may have overlooked.
Bottom Line?
With a dramatically expanded structural framework and targeted exploration underway, iTech Minerals is poised to redefine the gold-antimony potential at Reynolds Range.
Questions in the middle?
- How will the new east-west structural model impact the prioritisation of drill targets?
- What are the timelines and expected scale for the upcoming soil sampling and drilling programs?
- Could the expanded structural understanding influence joint venture negotiations or project valuation?
