Citizen awareness and access to independently verified data is important, especially when it comes to a resource as important as ground and surface water. The Stibnite Advisory Council launched the Independent Water Monitoring Program to give community members access to ground and surface water quality data from the Stibnite Gold Project verified by an objective third-party.

The goal of the Independent Water Monitoring Program is to enhance the transparency of the Stibnite Gold Project and help ensure the company’s data is representative of the environmental conditions present at site. To achieve this the Stibnite Advisory Council hired the Idaho Water Resources Research Institute from the University of Idaho to collect, analyze and report on ground and surface water samples in conjunction with an EPA-certified lab twice a year.

Through the program, the Idaho Water Resources Research Institute will visit the site twice a year to collect samples from nine different surface and ground water test sites, plus two quality control sites, to be analyzed for different chemical components. The samples are divided between Perpetua Resources and Idaho Water Resources Research Institute to monitor, test, and evaluate.

2021 Water Quality Data

The program collected its first samples in the summer of 2021. The first test results show the results between the two labs were consistent 97% of the time for surface and 98% of the time for ground water.


It is important that the community has full visibility into the Independent Water Monitoring Program. Below you will find all of the reports and summaries provided by the Idaho Water Resources Research Institute and press releases on the results of the program from the Stibnite Advisory Council.
