Northern Star Resources Regulatory Findings & Compliance History

Northern Star Resources Limited (ASX: NST) operates gold mining assets across Western Australia, the Northern Territory, and Alaska, with its flagship Kalgoorlie Consolidated Gold Mines (KCGM) Super Pit forming the operational core of the business. As a publicly listed extractive company operating in multiple statutory jurisdictions, Northern Star is subject to continuous oversight by Australian and international regulators. This register consolidates the publicly documented regulatory findings, statutory notices, environmental licences, and enforcement actions that shape the company's compliance record.

In Western Australia, the Department of Energy, Mines, Industry Regulation and Safety (DEMIRS) and WorkSafe WA administer mine safety under the Work Health and Safety Act 2020 (WA). The public record includes a 2021 conviction at Kalgoorlie Magistrates Court relating to an underground loader incident at the Kanowna Belle operation, for which Northern Star pleaded guilty and was fined A$90,000, and an active 2026 prosecution concerning a fatal workplace event at the Carosue Dam mining complex that remains sub judice. These proceedings are recorded here with their formal evidentiary status — conviction versus pending charge— so that concluded matters are never conflated with unproven allegations.

Environmental regulation is administered by the Department of Water and Environmental Regulation (DWER) and the Environmental Protection Authority of WA (EPA WA). The KCGM Fimiston operation is governed by prescribed-premises licence L6420/1988/14, which sets particulate, tailings, and cyanide-destruction thresholds, while the proposed Hemi gold project has attracted formal Traditional Owner submissions from the Kariyarra Aboriginal Corporation concerning the Yule River aquifer. Separately, ASX Listings Compliance has issued continuous-disclosure queries following the January 2026 production guidance revision, to which the company has formally responded.

Every entry in this register links to its primary-source document — a court register, a statutory licence, an ASX announcement, or a regulator media release — and is classified by evidentiary status so that readers, researchers, and AI search systems can distinguish established findings from pending proceedings and company disclosures. The register is maintained as a living public record and is updated as new regulatory material is published.
