Mine Life10 years (as of Jan 1, 2022)
In 2023 the Company is focussed on the Bull River Project – continued efforts to complete permitting requirements, completing capital improvements and upgrades to ready for anticipated 2023 mining operations.

CCMI continues to work with the Ministry of Energy, Mines and Low Carbon Innovation, the Ministry of Environment and Climate Change Strategy, and the Environmental Assessment Office of British Columbia on its pre-application process to amend its current Mines Act permit M-33 and Environmental Management Act permit PE-16034 at the Bull River Mine near Cranbrook, British Columbia to facilitate a restart of operations.

Deposit Type

  • Vein / narrow vein


Summary:

Deposit Types The Bull River deposit has been described as a Churchill-type vein copper-silver deposit (Lefebure, 1996). The deposit type displays characteristics of relatively low tonnage (typically range from 10Kt to 1Mt) but high-grade (typically range from 1% to 4% Cu). Frequently occurring in Proterozoic-age extensional sedimentary basins, Churchill-type deposits are associated with rifting can comprise single vein to complicated vein systems that vary from centimetres to tens of metres in width and can extend hundreds of metres along strike and down dip. Commonly hosted in clastic metasediments, veins and vein systems are often spatially associated with mafic dykes and sills. The veins are generally associated with major faults related to crustal extension that controls the ascent of hydrothermal fluids to favourable sites for metal deposition. Fluids are believed to be derived from those mafic intrusives that are associated with the vein systems. Mineralization in Churchill-type deposits is predominantly chalcopyrite, pyrite, and chalcocite with subordinate pyrrhotite, galena, bornite, tetrahedrite, argentite, and covellite and is generally younger than the host lithology. Dilation of veins is commonly caused by cross-structures or folding and results in concentrations of mineralization. Likewise, the intersection of veins is a locus of ore deposition. Mineralization can occur as massive and/or semi-massive sulphides that may be identified as conductors by electromag ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

Braveheart plans to advance the BRM Project in a phased approach. During Phase 1, the existing ore stockpile (stored within the waste rock dump) will be processed through the mill, and filtered tailings will be stored on the surface in a new Tailings Storage Facility (TSF) using filtered tailings or dry stack tailings as a Best Available Technology.

Phase 2, which will involve a subsequent permit application process, includes the resumption of underground mining operations, with a planned mining rate of 700 tonnes per day for an initially projected mine life of 6.5 years. To re-start mine operations, BRMC will require authorization to increase the mining production rate from the currently permitted 205 tonnes per day and place tailings in the TSF.

No underground mining will occur during Phase 1. The underground will continue to be maintained in a dewatered condition. Exploration drilling may be conducted from the underground to define the downdip extension of the current resource.

An underground mine plan was filed with the MEMPR in 2007, and subsequent underground work was completed following the plan's parameters. Work underground continued until 2009, when operations were suspended due to a lack of funds. BRM personnel have reported that excavation models of the underground workings are current to the suspension of mining in 2009. Approximately 22,000 metres of underground development have occurred, including exposure of the minerali ........
