Shirley Basin Mine Site
Shirley Basin, Wyoming
As a part of the Pathfinder acquisition, we now own the Shirley Basin and Lucky Mc mine sites in the Shirley Basin and Gas Hills mining districts of Wyoming, respectively, from which Pathfinder and its predecessors historically produced more than seventy-one million pounds of uranium, primarily from the 1960s through the 1990s. The Shirley Basin project is located in Carbon County, Wyoming, approximately 40 miles south of Casper, Wyoming. Conventional mine operations were suspended by Pathfinder in the 1990s due to low uranium pricing.
Acquired Historic Geologic, Engineering and Operational Data Allowing for Easier Transition to NI 43-101 PEA, Permitting and Operations
Together with property holdings of patented lands, unpatented mining claims, and private leases totaling nearly 3,700 acres (~1,500 hectares) at Shirley Basin, we also acquired all historic geologic, engineering and operational data related to the mine area.
The Company completed its Preliminary Economic Assessment on Shirley Basin January 27, 2015 (the “PEA”). The PEA estimates 8.8 million pounds Measured and Indicated Uranium Resources. It is estimated that a total of 6.3 million pounds of U3O8 may be produced from the project.
The application for the State permit to mine was filed in 2015, and other applications have been submitted since. All permits, licenses and authorizations are expected to be complete in 2021 H2. Additionally, we have engineering evaluations, designs and studies underway in preparation of the construction and operations at Shirley Basin.
The tailings facility at the Shirley Basin site is one of the few remaining facilities in the United States that is licensed to receive and dispose of byproduct waste material from other in situ uranium mines. We assumed the operation of the byproduct disposal site and have accepted deliveries since 2014 under several contracts.
