Mt Egerton Drill Hole Hits 46.2g/t Gold, Extending High-Grade Zone by 10 Metres

Mining By Maxwell Dee 3 min read

Black Horse Mining has reported exceptional high-grade gold results from its Mt Egerton project, including assays reaching 46.2 grams per tonne, extending known mineralisation vertically by 10 metres. The findings reinforce the potential for significant unmined gold lodes at shallow depths.

  • Hole 26MEDD004 yields up to 46.2g/t gold over 0.25m within a 4.4m mineralised zone
  • High-grade zone extended approximately 10 metres vertically above previous intercept
  • Core loss intervals mean reported grades are conservative estimates
  • Further targeted drilling planned to define resource extent and continuity
  • Geological setting comparable to major Victorian goldfields like Fosterville

Exceptional High-Grade Gold Intersected

Black Horse Mining Ltd has announced further promising results from its Mt Egerton Gold Project in Victoria, with drill hole 26MEDD004 revealing outstanding high-grade gold mineralisation. Assays from this hole include a remarkable 46.2 grams per tonne (g/t) gold over 0.25 metres within a broader 4.4-metre zone starting at 49.65 metres downhole. This intercept notably extends the previously reported high-grade zone from hole 26MEDD005 by approximately 10 metres vertically, suggesting a more substantial and continuous gold system than earlier understood.

Conservative Estimates Amid Core Loss Challenges

The drilling campaign encountered some core loss within the mineralised zones, a common challenge in weathered and altered ground conditions. Importantly, Black Horse Mining has taken a conservative approach by assigning zero grade to these unrecovered intervals, implying that the true grade of the mineralised zone could be materially higher than reported. This cautious reporting underlines the robustness of the results and the potential upside as sampling techniques improve in subsequent drilling phases.

Geological Context and Exploration Strategy

The Mt Egerton project lies within the Lachlan Fold Belt, a prolific gold province that hosts world-class deposits such as the Fosterville Gold Mine. Mineralisation at Mt Egerton is structurally controlled within quartz reef systems, with higher-grade shoots associated with fold hinges, fault intersections, and dilational zones. Black Horse Mining’s current and planned drilling focuses on testing down-plunge extensions of known high-grade zones, vertically stacked or parallel reefs near historic workings, and deeper targets below historical mining depths where modern exploration techniques have yet to be applied.

Implications for Resource Growth and Future Drilling

These latest results provide compelling evidence that significant unmined gold lodes remain at relatively shallow depths within the Mt Egerton gold field. The company is preparing a follow-up drilling campaign designed to better define the extent and continuity of these high-grade zones. By integrating geological insights from structural controls and historic workings, Black Horse Mining aims to identify repeatable high-grade shoot geometries that could substantially enhance the project’s resource potential.

Pending Results and Next Steps

While results from holes 25MEDD002, 25MEDD002A, and 25MEDD003 are still pending, the current findings already underscore the early-stage exploration upside at Mt Egerton. The company’s methodical approach, combined with the geological setting’s proven potential, positions Mt Egerton as a promising asset in the Victorian goldfields landscape. Investors and analysts will be watching closely as further assay results and drilling updates emerge.

Bottom Line?

Black Horse Mining’s latest high-grade gold intercepts at Mt Egerton set the stage for a pivotal phase of exploration that could redefine the project’s resource outlook.

Questions in the middle?

  • How will pending assay results from other drill holes influence the overall resource model?
  • What improvements in drilling and sampling techniques will be implemented to reduce core loss?
  • Could deeper or parallel lodes at Mt Egerton rival the high-grade shoots seen at nearby world-class deposits?
