The safety inspectors from Chile’s National Geology and Mining Service (Sernageomin) visited Pascua Lama and found excess fine particulates suspended in the air, reported the La Tercera.

Sermageomin has stated that, pre-stripping is taking place at Pascua Lama.

The drilling and blasting of the mine, emptying of the material in Pascua Lama’s waste dump are reportedly generating the air quality problem.

According to Barrick, an action plan was immediately formulated to address the regulator’s specific concerns, against the pre-stripping activities.

Barrick CEO Jamie Sokalsky remarked that the delays in the earthworks and underground for the Pascua Lama process plant were primarily responsible for a change in the shift in schedule for the project.
