E79 Gold Mines has reported outstanding high-grade copper and gold assay results from its Mountain Home Project in the Northern Territory, significantly expanding the known mineralised area and setting the stage for drilling in 2026.
- High-grade copper assays up to 35.9% Cu and elevated gold detected
- Expanded mineralised footprint with new parallel trends identified
- Access agreement secured with local pastoralist enabling site access
- Heritage survey completed; approvals expected by December 2025
- Large-scale co-funded airborne gravity survey scheduled for December
Exploration Success at Mountain Home
E79 Gold Mines Limited (ASX, E79) has announced a successful reconnaissance field program at its Mountain Home Copper-Gold Project in the Northern Territory. Recent rock chip sampling and geological mapping have revealed exceptionally high-grade copper mineralisation, with assays reaching as high as 35.9% copper and notable gold values. These results extend the known mineralised footprint beyond previous boundaries, highlighting new parallel trends and broadening the project's exploration potential.
Strategic Access and Heritage Approvals
Crucially, E79 Gold has secured a key access agreement with the local pastoralist, ensuring unhindered site access for upcoming exploration activities. The company has also completed the fieldwork component of an Aboriginal Heritage Survey, with results and potential heritage licence approvals anticipated in the December quarter. These regulatory milestones are expected to clear the way for initial drilling activities planned for 2026, following the wet season.
Geophysical Survey to Unlock Regional Structures
Complementing the ground exploration, E79 Gold is set to commence a large-scale airborne gravity survey in December 2025. This co-funded program aims to map major geological structures and prospective rock units over a 350 square kilometre area, providing critical insights into the broader mineral system beneath cover. The survey is supported by a Northern Territory Government grant, underscoring the project's regional significance.
Geological Context and Potential
Consulting geologist Carl Brauhart noted that the Mountain Home Project exhibits characteristics typical of intracratonic copper-gold systems, akin to world-class deposits such as Olympic Dam and Tennant Creek. The presence of elevated bismuth alongside copper and gold suggests a possible affinity with iron-oxide copper-gold (IOCG) deposits, which are known for their scale and grade. Detailed mapping has identified brittle sinistral faults hosting mineralisation in quartz breccias, pointing to structural controls that could guide future exploration targeting.
Looking Ahead
With the groundwork laid through successful sampling, mapping, and regulatory progress, E79 Gold is poised to advance Mountain Home into its next phase of exploration. The combination of high-grade surface results, strategic access, heritage approvals, and upcoming geophysical data positions the project well for discovery potential. Investors and analysts will be watching closely as initial drilling results emerge in 2026, potentially unlocking significant value in this underexplored Northern Territory copper-gold province.
Bottom Line?
E79 Gold’s Mountain Home project is entering a critical phase, with high-grade results and regulatory progress setting the stage for drilling that could redefine its resource potential.
Questions in the middle?
- Will the upcoming drilling confirm the scale and continuity of the high-grade mineralisation?
- How will the airborne gravity survey refine exploration targets across the broader region?
- What impact will the Cue Gold Project acquisition have on E79 Gold’s overall growth strategy?
