Introduction to the Situation at Garpenberg Mine

The Garpenberg mine has recently faced a period of unusually high seismic activity, which significantly impacted its operations. As of late March 2026, this seismic activity has reportedly decreased, allowing for the possibility of resuming mining production, albeit at much lower levels than typically expected. In this article, we will delve into the consequences of this seismic activity and the subsequent steps being taken to address the ongoing challenges at the mine.

Current Mining Operations Status

In the first quarter of 2026, the throughput at the Garpenberg mine was nearly 0.8 million tons (Mton), falling short of the anticipated 0.9 Mton. Currently, mining operations are set to begin at a marginal rate of roughly 30% of the mine's designed capacity of 3.7 Mton annually, which translates to an expected production of approximately 100,000 tonnes per month in the second quarter. This preliminary output assessment comes with notable uncertainties as inspections of certain areas of the mine remain incomplete.

Major damages caused by the seismic events have been primarily found in the Lappberget ore body, the key section of the mining site. Inspections in these areas highlighted that mining activities are unlikely to resume in 2026. While a significant portion of the mine's infrastructure—such as crushers and workshops—has remained largely intact, essential systems like ventilation and water management have suffered substantial damage, necessitating extensive renovations that are projected to take several weeks.

Impact on Financials

The financial implications of these disruptions are profound. For the first quarter of 2026, the mine's EBITDA is expected to decline by around SEK 400 million, primarily due to the diminished output and operational inefficiencies. The damages have raised pressing questions regarding the mine's long-term production capacity and profitability.

Preparations and Inspections

Comprehensive inspections of the Garpenberg mine have nearly concluded, but the full safety evaluations are still in progress. The aim is to prepare the mine for a gradual resumption of operations in the least affected areas, excluding those severely impacted in Lappberget. The expectation is that operations in other parts of the mine, under normal circumstances, will proceed effectively, allowing Boliden to mitigate some of the production downturn.

Moving Forward

Looking ahead, Boliden is cautiously optimistic about enhancing production levels as the year progresses. There are indications that production may increase in the latter half of the year, contingent on safety assessments and maintenance completion. Although zinc grade levels may take a slight hit, the silver grades reportedly show a potential increase, further complicating the revenue landscape.

Communication and Future Outlook

To keep stakeholders updated, Boliden will hold a press and analyst conference on March 26, 2026. Interested parties can join the discussion via webcast or telephone registration to gain insights into future operational strategies and market adjustments as they relate to the ongoing seismic situation at the Garpenberg mine.

The coming weeks will be crucial for the mine, as finalizing the inspections and beginning repairs will dictate the pace and extent of operational recovery. Stakeholders will be keenly watching these developments as they unfold, hoping for a swift and smooth transition back to full functionality.
