North Stawell Minerals Targets High-Grade Gold Extensions at Darlington

North Stawell Minerals has launched a 600-800 metre diamond drilling program at its Darlington Project, aiming to extend previously identified high-grade gold zones that echo historic Victorian gold trends.

  • 600-800m diamond drilling program underway at Darlington
  • Targets extensions of high-grade gold mineralisation open in all directions
  • Darlington mineralisation parallels historic Mariners Lodes with grades up to 30 g/t Au
  • Drilling focuses on a potential high-grade gold shoot within broader vein system
  • Darlington remains NSM’s key 2026 exploration priority

Diamond Drilling Targets High-Grade Gold Extensions

North Stawell Minerals (ASX:NSM) has kicked off a 600 to 800 metre diamond drilling campaign at its Darlington Project in western Victoria, seeking to follow up on a string of compelling high-grade gold intercepts. The program aims to test for extensions beneath previously reported shallow mineralised zones that run parallel to the historic Darlington Mine trend, which remains open along strike and at depth.

Significant prior drill results include standout intercepts such as 2.3 metres at 29.3 g/t gold from 108.2 metres and narrower zones hitting 82 g/t gold within that interval. These grades echo the style and tenor of mineralisation seen at the nearby Mariners Lodes, a prolific Victorian gold producer that historically delivered grades between 28 and 30 g/t gold. NSM’s Executive Director Bill Reid highlighted the geological and structural similarities between Darlington and Mariners, underscoring the potential for a repeat of this high-grade gold system.

Strategic Focus on Darlington Within a Larger Gold Corridor

The Darlington Prospect forms a critical part of NSM’s 445 square kilometre North Stawell Project, which straddles a gold-prospective structural corridor immediately north of the Stawell Gold Mine. This corridor hosts a series of mineralised trends controlled by basalt geology, which plays a key role in focusing gold mineralisation in the region.

Darlington’s mineralisation is interpreted as "Mariners-type", occurring as structural splays above a deeper basalt layer. The prospect includes two parallel veins spaced about 100 metres apart, with historic production records from the eastern vein showing 2,347 ounces of gold at 18.2 g/t. The current drilling program is focused on the western vein, specifically targeting a high-grade shoot identified 400 metres south of the historic mine.

Drilling to Test High-Grade Shoot and Broader Vein System

The ongoing diamond drilling will comprise 2 to 3 holes designed to step out 70 metres along strike from previous high-grade intersections and 300 metres south of the historic Darlington Mine. The objective is to confirm the presence of a vertically plunging, high-grade gold shoot within a broader planar vein system that remains open at depth and along strike.

Recent aircore drilling results have supported the targeting of this high-grade shoot, which is hosted within brecciated quartz-carbonate veins. The geological setting, including the controlling basalt units, is critical as these structures influence the flow of gold-bearing fluids and the localisation of mineralisation.

NSM’s renewed focus on Darlington reflects the project’s potential to deliver high-grade, narrow-vein gold mineralisation analogous to the historic Mariners Lodes, a model that has attracted significant investor attention across Victorian gold projects in recent years.

Bottom Line?

Darlington’s drilling will be a key barometer for NSM’s ability to replicate historic high-grade gold systems, with assay results poised to shape the project’s near-term trajectory.

Questions in the middle?

  • Will the diamond drilling confirm the interpreted high-grade gold shoot beneath previous intercepts?
  • How might these results influence NSM’s resource definition and development timeline at Darlington?
  • Could Darlington’s mineralisation unlock further exploration potential along the broader Darlington-Caledonia trend?
