Paramount Gold Nevada Corp. has filed its mining plan of operation for its Grassy Mountain site with the Bureau of Land Management, which has launched its environmental review of the proposed mine.

That review will begin with the development of the environmental impact statement by HDR Inc., a consulting firm., according to a news release from Paramount Gold, which announced the filing last week.

The company is also in the process of preparing a preliminary feasibility study for the proposed mine “to exploit the high-grade gold core” at the Grassy Mountain site, located south of Vale, the company said.

Calico Resources USA, a subsidiary of Paramount since 2016, continues exploratory activities at the site, it said.

Paramount is going through the process of obtaining federal permits and permits from Oregon state agencies including the Department of Geology and Mineral Industries and the Department of Environmental Quality.

With the filing of the plan of operation, Paramount plans to file its consolidated permit application in early 2018, the company said.

State agencies involved in the consolidated permit process also include the Water Resources Department and the Oregon Department of Fish and Wildlife.

Representatives of these agencies and from the company participated in a teleconference meeting Wednesday as members of the tailings facility design subcommittee began their review of Paramount’s conceptual design for the tailings storage facility.

According to the plan, prepared by Golder Associates, the storage facility would be situated east of the mine site and planned process and milling facilities and would have a capacity of up to 3 million dry tons.

The life of the mine is projected to be 10 years, and the tailings storage facility is being designed to have no discharge.

Tailings from the mill will be moved to storage by gravity flow or by a pumping system, according to the plan, and as tailings are settled out of the slurry in the facility, any free water will be pumped back to the mill for reuse. Two embankments were are planned to impound the tailings.

Randy Jones, of DEQ, said some of the permits which could be required include a water pollution control permit, solid waste permit, an air quality permit and an industrial storm water permit.

Some of the issues the subcommittee will be looking at are longevity of the storage facility and the materials proposed for building the embankments.

Philip Milburn, with ODFW in Malheur County, said the storage facility would need to have some form of fencing or cover to protect wildlife.

There was no announcement of when the next meeting of this subcommittee will be held.

It will report back to the Technical Review Team, which is the full team of state agencies, which will review Paramount’s permit applications develop the permit applications.

Other subcommittees also meet from time to time, as well as the full review team.
