Deposit Type

  • Vein / narrow vein
  • Mesothermal


Summary:

The Bell Creek properties are underlain by carbonate altered, greenschist facies Archean-aged, metavolcanic and clastic metasedimentary rock. The metavolcanic portion of the stratigraphy represents the lower portion of the Tisdale Assemblage (Brisbin, 1997; Pyke, 1982). The Krist Formation is absent from the Property (Berger, 1998). The clastic metasedimentary rocks belong to the Porcupine assemblage. Lithologies generally strike east-west, to west-northwest, and are steeply dipping. Regionally, gold bearing structures most commonly form in relatively competent volcanic rocks intruded by felsic porphyry stocks and dykes prior to the deposition of the Timiskaming Assemblage sedimentary rocks. Porphyries dating from 2691 ± 3 Ma to 2688 ± 2 Ma intruded the already folded and faulted greenstone sequences and initiated the mesothermal systems with the formation of associated albitites. Observations of pyrrhotite and gold-mineralized clasts within Timiskaming conglomerates at both the Pamour and the Dome mines, located approximately 5km southeast and 10km south-southwest of the Property respectively, suggest a prolonged gold deposition event from the creation of the steep south dipping DPF zone up to the latest episode of crustal stabilization (Butler, 2008). Berger (1998) describes the gold mineralization in the Bell Creek area as occurring along selvages of quartz veins and wall rocks, in stylolitic fractures in quartz veins, in fine grained pyrite and pyrrhotite, and in associ ........


Mining Methods

  • Dry waste backfill


Summary:

Bell Creek is a part of the Timmins operation which is also includes the Timmins West mine, which both feed the Bell Creek mill.

Bell Creek Mill produces gold in the form of doré bars. The bars are a blend from the Timmins West Mine and Bell Creek. The doré bar’s historical weighted average gold grade has been 84.9% and has ranged between 61.6% and 91.7%.

Bell Creek consists mainly of multiple nearly parallel narrow gold veins that are steeply dipping. This steepness of the veins allows for longhole extraction methods. Main mining veins trend East-West with some convergence observed between the 1185mL and down to 1450mL, including some north-south trending.

The existing underground infrastructure at Bell Creek is listed below:
• The 6.3 m by 2.6 m three compartment shaft, 1080m deep.
• Main shaft stations at the 300L, 535L, 790L, and 1000L.
• Ore and waste rockbreakers and bins at 1000L, and a loading pocket at 1040L.
• Ventilation raises to surface and internal ventilation raises underground.
• The main ramp from surface to approximately 1450L depth.
• Mine dewatering facilities.
• Electrical distribution and communications.
• Compressed air and service water distribution.
• Maintenance facilities.

The Bell Creek mineral reserves will continue to be extracted using underground mining methods and is accessed via the existing shaft and portal/ramp from surface.

Reserves at June 30, 2022:
Minimum cut-off grades used for the Mineral Reserve are 2.2g/t gold for stoping, 2.0 g/t gold for incremental stoping and 1.5 g/t gold for ore development. Cut-off grade calculations used estimated mining costs of $78.63 per tonne, site G&A costs of $2.51 per tonne, milling costs of $18.38 per tonne, mining recovery of 95%, external dilution of 25% and a metallurgical recovery rate of 94.5%.
Mineral resources are estimated using prices of $1,500 per ounce of gold.
