Peel Mining’s latest drilling at the Southern Nights Complex in NSW reveals substantial silver-zinc-lead intercepts and promising depth extensions, reinforcing the project’s growth potential ahead of a planned corporate restructure.
- Broad high-grade silver-zinc-lead intercepts at Link Zone South
- Deep diamond drilling shows sulphide mineralisation beyond current resource
- Southern Nights Complex remains open along strike and at depth
- Current Mineral Resource Estimate near 10 million tonnes with significant metals
- Ongoing assays and drilling to guide future resource updates
Strong Silver-Zinc-Lead Results at Link Zone South
Peel Mining Limited (ASX:PEX) has delivered a fresh wave of encouraging assay results from recent Reverse Circulation drilling at its Link Zone South target within the Southern Nights Complex (SNC) in New South Wales. The standout intercept came from hole WTRC287, which returned a blistering 2 metres grading 554 grams per tonne (g/t) silver, 18.2% zinc, and 11.27% lead starting at 130 metres depth. Other holes like WTRC284 and WTRC288 also recorded broad zones of silver-rich polymetallic mineralisation, with widths up to 24 metres and silver grades exceeding 200 g/t in some intervals.
These results confirm the continuity of mineralisation previously identified at Southern Nights and highlight the presence of high-tenor sulphide zones, reinforcing the prospect’s potential as a significant silver-zinc-lead resource. The mineralisation remains open along strike and both up and down dip, suggesting further upside from ongoing exploration.
Depth Extension Beyond Current Resource Boundaries
Adding to the excitement, Peel’s diamond drill-hole WTRCDD300, designed to test deeper extensions of the Link Zone, intersected multiple zones of visual sulphide mineralisation well beyond the existing Mineral Resource envelope. While assays for this hole are still pending, visual logging indicated semi-massive to vein-hosted sulphides with combined zinc and lead estimated around 8% over approximately 5 metres at depths exceeding 570 metres.
This discovery of sulphides 70 metres beyond the current resource boundary underscores the SNC’s potential for vertical growth and supports the interpretation of the deposit as a large, laterally and vertically extensive polymetallic system. Peel’s Managing Director Nick Woolrych noted that this deep mineralisation “clearly demonstrates that the system remains open and reinforces SNC’s significant growth potential.”
Southern Nights Complex: A Major Emerging Polymetallic Asset
The Southern Nights Complex is a silver-rich polymetallic system hosted in a volcanic-sedimentary sequence typical of volcanic-associated massive sulphide (VAMS) or volcanic-hosted massive sulphide (VHMS) deposits. The current Mineral Resource Estimate, updated in April 2025, stands at nearly 10 million tonnes containing 16.8 million ounces of silver, 277,000 tonnes of zinc, 119,000 tonnes of lead, 35,400 tonnes of copper, and 131,000 ounces of gold.
These grades and metal quantities position Southern Nights as a significant asset with strong leverage to rising silver prices and critical mineral demand. Peel’s ongoing drilling campaigns, including the recent program reported here, aim to expand this footprint further. Earlier this year, Peel launched a targeted drilling program to boost silver-rich resources at Southern Nights, complementing these latest assay results and continuing the company’s methodical approach to resource growth.
Peel’s recent corporate moves, including a $214 million deal with Aeris Resources and a planned spin-off of remaining assets into a new ASX-listed entity, hinge on the strength of projects like Southern Nights. The robust assay results and depth extensions reported now add tangible substance to the company’s strategic positioning and upcoming IPO plans. This is evident in the company’s view of Southern Nights as the “cornerstone asset” of the proposed demerger.
Pending Assays and Next Steps
While assays from some drill holes, notably the deep diamond drill hole WTRCDD300, remain outstanding, Peel anticipates these results will further clarify the resource’s scale and grade. The company plans to integrate the new data into future Mineral Resource updates and follow up with targeted drilling to test extensions and repetitions of the high-grade zones.
With drill spacing at Link Zone South still relatively broad; up to 80 metres; the potential for discovering additional discrete mineralised shoots remains high. The presence of mineralisation extending into the weathered profile also hints at near-surface oxide and supergene enrichment zones that could enhance project economics.
Given Peel’s track record of consistent exploration success at Southern Nights and the recent drilling to boost silver-rich resource, the market will be watching closely for upcoming assay releases and resource model revisions that could further underpin the company’s growth narrative.
Bottom Line?
Peel Mining’s latest drilling confirms Southern Nights as a growing polymetallic system with high-grade silver zones and promising depth extensions, setting the stage for resource upgrades and strategic corporate moves.
Questions in the middle?
- How will pending assay results from the deep diamond hole influence the Southern Nights resource model?
- What are the implications of the broad drill spacing for discovering additional high-grade zones?
- How might ongoing exploration at Southern Nights impact Peel Mining’s planned demerger and IPO timeline?
