Sandvik DR413i rigs for Glencore Alumbrera restart: drilling strategy notes for engineers

First reported on International Mining – News
30 Second Briefing
Sandvik will supply three DR413i rotary blasthole drill rigs to Glencore for the restart of the Bajo de la Alumbrera copper mine in Argentina, with the order booked in Q1 2026. The first DR413i is due on site in April 2026, with the remaining two units scheduled for delivery in Q4 2026, supporting pre-stripping and production drilling for the brownfield operation. The deal signals early capital deployment into large-diameter rotary drilling capacity ahead of full-scale mine recommissioning.
Technical Brief
- i-series automation architecture allows high-precision drilling control, data capture and remote monitoring integration.
- Glencore’s selection of three identical rigs simplifies spares, maintenance planning and operator training for restart.
- Early drill fleet commitment de-risks pre-strip sequencing and blast design ahead of mill recommissioning.
- Brownfield restart benefits from modern high-capacity drills, likely reducing unit drilling and blasting costs.
- Similar brownfield copper restarts are increasingly standardising on large, automated rotary rigs for pre-strip.
Our Take
Multiple recent items in our database show Sandvik placing automation-ready surface drills at copper operations – for example the DR410i with AutoMine Surface Drilling at Mariana Minerals’ Copper One mine in Utah – which suggests the DR413i units for Glencore’s Bajo de la Alumbrera copper mine are likely part of a push to standardise autonomous-capable fleets across major copper pits.
With copper one of the most frequently covered commodities in our Mining category, the Alumbrera restart in Argentina positions Glencore to reintroduce a brownfield source of supply at a time when many other copper stories in our coverage are still at expansion or ramp-up stage rather than restart.
The 2026 delivery schedule for the three DR413i rigs implies that pre-stripping and early production drilling at Bajo de la Alumbrera will be tightly sequenced, so any slippage in Sandvik’s Q2–Q4 2026 handover could have a direct impact on Glencore’s restart timeline and contractor planning on site.
