Placer gold was first discovered in the early 1860’s in the Bull River Canyon and numerous small mine workings have been excavated in the area since that time. No work was reported on the Bull River Mine site until 1968 when Placid optioned the property. Initially, Placid was targeting dyke structures similar to those found at the Sullivan Mine and other Purcell Supergroup deposits but instead intersected supergene-type copper mineralization and an underlying copper-silver vein system.

The Bull River Mine property hosts the historic Dalton Mine which started milling on October 1, 1971, and continued from two open pits until June 10, 1974, producing 7,260 t (16.0M lb) of copper, 6,354kg (204,274oz) of silver, and 126kg (4,055oz) of gold from 471,900t milled See BC MINFILE. The Dalton Mine was owned by Placid Oil Co. (Placid). Placid attempted to go underground to access additional resources but was unsuccessful in getting the portal collared in blocky ground (Snowden 2013). Ross Stanfield purchased the assets of the Dalton Mine from Placid on March 5, 1976, and transferred the assets to Bul River Mineral Corporation under incorporation on March 17, 1976.
Over the next several years, exploration drilling at the Bull River Mine indicated the possibility of further resources below the excavated pits. A portal was collared in 1997 and exploration development commenced allowing for a more detailed drilling program.
In May 26, 2011, the Stanfield Mining Group of Companies ("SMG") including the Bull River Mine was placed under creditor protection and a new management group was put into place. While under creditor protection, several NI 43-101 compliant Resource Statement Technical Reports were produced. Roscoe Postle and Associates (RPA) completed two NI 43-101 compliant technical reports in 2011 and 2012 which included extensive QA/QC to bring historical geological information into compliance. In February 2013, Snowden Mining Industry Consultants released a NI 43-101 compliant technical report which included new drilling results and interpretation that described the current resource at the Bull River Mine.
In December 2014, a restructuring plan was approved by the BC Supreme Court and SMG creditors. The restructuring plan included the transfer of all ("SMG") mining properties and assets to Purcell Basin Mineral Inc. The current mineral inventory includes 139 mineral claims, two mining leases and a worker's camp site.
With the majority of the original infrastructure still in place from the previous operators and the expected modest capital requirements to restart the Bull River Mine, Purcell Basin Mineral is actively working on a submission for an updated Mines Act permit application. In January 2015, the company held an open house in Cranbrook, BC to provide the public and any stakeholders with an overview of the project and its proposed operations. Consultation and communication has and will be continuing through-out the regulatory process.
