Rosemont Mine’s parent Hudbay Minerals to start drilling on west slope of Santa Ritas | Local news

The permit covers activities on 40-plus acres near the intersection of Santa Rita Road and National Forest Road 505, also known as Helvetia Road.

In notifying Pima County of the company’s drilling plans, Hudbay’s David Krizek said exploration activities and support activities such as road maintenance will be conducted between Sept. 16 this year and Jan. 15, 2021.

The permit requires Hudbay to take mitigation steps to insure its activities don’t generate dust, said PCDEQ Director Ursula Nelson.

The fact that the company plans to build water and power lines near the Santa Ritas for Rosemont played into its decision to do the upcoming drilling, Lauzon told the Green Valley News.

The lines are planned for along Santa Rita Road, and the drilling is planned for near that road, Hudbay’s Pima County permit shows.

Among the questions Hudbay would not respond to from the Star were whether it would also use public land for mining or waste disposal operations that resulted from the drilling.

It also declined to say if it would, if this drilling uncovered economically good copper deposits, attach any mining plans for these lands to its existing Rosemont plan, or file for a separate plan.

If it lumped this area with its Rosemont plan, that would likely trigger a revision of the mine’s environmental impact statement, meaning more delays for that embattled, nearly $2 billion construction project.
