USGS releases first study to assess global earthquake risk to mineral supplies
Earthquakes have the potential to substantially affect mining operations, leading to supply chain disruptions that adversely affect the global economy.
Rise Gold (CSE: RISE) has announced that it is one step closer to the reopening of the historic, past-producing Idaho-Maryland gold mine in California.
In a press release, the US company reported that the Nevada County Board of Supervisors unanimously approved the contract for Raney Planning & Management to prepare the environmental impact report and conduct contract planning services on behalf of the County for the project.
Idaho-Maryland was reportedly the second-largest gold mine in the United States in 1941
According to Rise, this is a critical milestone in the processing of the Use Permit application. Thus, Raney will begin work immediately to review the technical studies submitted by the miner and kickstart the preparation of the draft EIR.
Once a final EIR is submitted to the County, its members certify the environmental document and consider approval of the Use Permit and Reclamation Plan at a public hearing. Rise expects the entire process to be finalized by sometime between December 2020 and May 2021.
The Idaho-Maryland project is Rise Gold’s main asset. It is located in the Grass Valley mining district of northern California and was one of the most productive and best known gold mines in the United States, with gold production dating back to 1863.
The mine was active for almost a century and during that period it produced over 2.4 million ounces of gold at an average mill head grade of 17 gpt gold.

“With Threat of Superfund Designation, RISE Gold Must Cleanup Existing Idaho-Maryland Mine Tailings”

EXCERPT:
“While Canadian mining company RISE Gold Corp was promoting the gold mine potential and alluring prospects of gaining permits to reopen the Idaho-Maryland Mine (IM Mine) in Grass Valley, CA, federal and state regulatory agencies were focusing on the polluted tailings that cover most of the 56.4 acre site and taking steps leading towards a Superfund Designation.
“There has been little public disclosure of the contaminated legacy IM Mine tailings, but correspondence from the EPA dated Sept 26, 2019 indicates that IM Mine’s potential designation as a Superfund site was conditionally deferred because RISE entered into a cleanup contract with the California Department of Toxic Substance Control (DTSC).
“On August 13, 2019, RISE Gold Corp CEO Ben Mossman signed agreements to cleanup the site, also known as the Centennial site. According to the DTSC records, RISE has been dealing with this issue from at least as early as March 13, 2019, when the first Scoping Meetings with the DTSC took place.”
