Niocorp Developments Ltd announced Thursday that it had struck a deal for constructing a new natural pipeline to serve its proposed mine in southeast Nebraska. The company said in a news release that it has signed an agreement with Rockies Express Pipeline LLC to build a 27.8-mile natural gas pipeline that will supply its planned Elk Creek Superalloy Facility. The agreement calls for Rockies Express to design, build and operate the pipeline, which will run from its main gas line in Marshall County, Kansas, to the site near Elk Creek in Johnson County. Niocorp would contract separately for the purchase of the natural gas to be carried by the pipeline. Niocorp said the deal is worth $63 million over 11 years and is dependent on the mining project going forward. The pipeline would still need government regulatory approval, which Niocorp said Rockies Express would be responsible for securing.
