Hasbrouck Mountain is an open-pit development project owned by WK Mining (USA) Ltd., a subsidiary of West Vault Mining Inc. (“West Vault”). Hasbrouck Mountain is located in the northern portion of Esmeralda County, Nevada, approximately 8 kilometers south of Tonopah, Nevada.

On March 8, 2023, West Vault filed a Pre-Feasibility Study (PFS) for the Hasbrouck Project, updating a September 2016 PFS for recent economic conditions. The Hasbrouck Project will utilize two separate heap leach facilities located approximately 8 kilometers apart. The Three Hills Mine (not subject to Royal Gold royalty) will be constructed and operated first. The Hasbrouck Mine will be constructed after production commences at the Three Hills Mine, and it will be ready to produce when Three Hills Mine ceases production after two years as a 15,900 tonne per day heap leach operation.
