A company’s application to conduct exploratory borehole drilling for uranium in the Tallahassee neighborhood west of Canon City has been denied.
The Mined Land Reclamation Board on Oct. 28 denied the application from Black Range Minerals that would have allowed development of an underground borehole extraction experiment in the Tallahassee Creek area. As presented, the application would have proceeded under the minimal requirements of a prospecting permit.
Objections to the proposal were filed by opponents including Tallahassee Area Community, Inc., Coloradoans Against Resource Destruction and the Information Network for Responsible Mining.
“Under Colorado law, the difference between prospecting activities versus mining activities equates to a big difference in how carefully regulators review the permit and how well water quality will be monitored and protected,” said attorney Jeff Parsons, who represented the opponents and Tallahassee resident Kay Hawklee in the proceedings. “This well-reasoned decision prevents Colorado from becoming a laboratory for untested uranium technologies that haven’t yet proven they can be utilized without polluting the watershed.”
Australia-based Black Range Minerals initially started exploring for uranium in the Taylor Ranch area west of Canon City in 2008 and got approval from the Fremont County Commission in 2010 to expand exploration on an additional 2,220 acres of property known as the Hansen Deposit, which is believed to be the largest uranium deposit in the district.
Black Range proposed to the state to use underground borehole mining, dubbed uranium fracking. The process involves drilling a hole up to 24 inches in diameter into a uranium deposit, lowering a rotating nozzle into the ground, blasting a highpressure water jet stream into the rock in order to fracture it and develop an underground cavern before pumping a uranium-bearing slurry back to the surface for processing.
Black Range’s proposal submitted to the state anticipated the development of the underground borehole passing through an unconfined drinking water aquifer in the Tallahassee Creek basin, but omitted a complete water-quality monitoring plan, Parsons said.
“The proposal that Black Range Minerals submitted was so minimalist that the company didn’t even identify the location of the main borehole or the detailed water-monitoring regime normally required for mining activities,” he said.
“This was an attempt by Black Range Minerals to get its mining operation going on the quick,” said Cathe Meyrick, president of Tallahassee Area Community group. “If we’re going to have an uranium mine next door, we expect the state to require a thorough review, including a comprehensive water monitoring plan and have enough protections in place to ensure that our drinking water isn’t contaminated.”
