Underexplored Antimony Veins at Reynolds Range Pose Drilling Risks for iTech
iTech Minerals has identified two extensive high-grade antimony zones at its Reynolds Range project in the Northern Territory, revealing significant mineralisation previously overlooked. The company plans to commence drilling later this year to explore these promising targets further.
- Two separate high-grade antimony zones over 300m long at Sabre and Falchion prospects
- Rock chip assays up to 30.6% antimony and 24 g/t gold
- Historical drilling largely did not assay for antimony, leaving zones underexplored
- Broader antimony soil anomaly extends over 6km, suggesting a large mineralising system
- Heritage approvals secured; drilling planned for late 2025
Discovery of High-Grade Antimony Zones
iTech Minerals Ltd has announced the identification of two distinct high-grade antimony zones at its Reynolds Range project in the Northern Territory. These zones, located at the Sabre and Falchion prospects, each extend over 300 metres and exhibit impressive grades, with rock chip samples returning up to 30.6% antimony and 24 grams per tonne gold. This discovery marks a significant development for the company, highlighting mineralisation that had been largely overlooked in previous exploration efforts.
Historical Exploration and New Insights
Previous explorers focused primarily on gold mineralisation and did not routinely assay for antimony, resulting in these high-grade zones remaining underexplored. Moreover, the antimony sulphides have undergone deeper weathering, reducing surface outcrop visibility and contributing to the zones being missed. iTech’s recent detailed mapping and rock chip sampling have revealed continuous mineralisation at surface, with thicknesses exceeding 14 metres in some areas. The zones appear open along strike and at depth, presenting compelling targets for further drilling.
Regional Significance and Broader Anomaly
The Sabre and Falchion prospects are part of a larger antimony mineralising system within the Reynolds Range, with a broader soil anomaly extending over 6 kilometres. This suggests the potential for additional high-grade veins concealed beneath thin cover. The project area lies within the Stafford Gold Trend, a region known for significant mineralisation, and benefits from accessible infrastructure, including proximity to the Stuart Highway.
Upcoming Drilling Program and Approvals
iTech has secured heritage approvals to proceed with drilling and is currently finalising government permits. The planned drilling program, expected to commence in late October or early November 2025, will focus on testing the depth extent of the high-grade antimony veins at Sabre and Falchion. Additionally, the program will target other high-priority gold prospects identified through recent geophysical surveys. This drilling campaign represents a critical next step in validating the size and economic potential of the newly identified antimony zones.
Strategic Partnerships and Future Outlook
iTech Minerals also maintains a strategic partnership with Sociedad Química y Minera de Chile (SQM), which is involved in developing the Reynolds Range lithium project, underscoring the company’s broader focus on critical minerals. The discovery of substantial antimony mineralisation adds another dimension to the project’s value proposition, potentially positioning Reynolds Range as a significant source of this critical metal, which is increasingly important for emerging technologies.
Bottom Line?
With drilling imminent, iTech Minerals is poised to unlock the full potential of Reynolds Range’s high-grade antimony system, a development that could reshape its resource profile and market standing.
Questions in the middle?
- What will the upcoming drilling reveal about the true extent and continuity of the antimony zones?
- How economically viable are the antimony deposits given their grade and thickness, and what metallurgical challenges might arise?
- Could further exploration uncover additional high-grade antimony veins beneath the broader soil anomaly?
