Deposit Type

  • Mesothermal
  • Vein / narrow vein
  • Intrusion related


Summary:

Greenstone-hosted quartz-carbonate vein deposits typically occur in deformed greenstone belts of all ages, especially those with variolitic tholeiitic basalts and ultramafic komatiitic flows intruded by intermediate to felsic porphyry intrusions, and sometimes with swarms of albitite or lamprophyre dykes. They are distributed along major compressional to trans-tensionalcrustal-scale fault zones in deformed greenstone terranes, commonly marking the convergent margins between major lithological boundaries, such as volcano-plutonic and sedimentary domains. The large greenstone-hosted quartz-carbonate vein deposits are commonly spatially associated with fluvioalluvial conglomerate (e.g., Timiskaming conglomerate) distributed along major crustal fault zones (e.g., Destor Porcupine Fault). This association suggests an empirical time and space relationship between large-scale deposits and regional unconformities.

These types of deposits are most abundant and significant, in terms of total gold content, in Archean terranes. However, a significant number of “Tier 1” deposits are also found in Proterozoic and Palaeozoic terranes. In Canada, they represent the main source of gold and are mainly located in the Archean greenstone belts of the Superior and Slave provinces. They also occur in the Palaeozoic greenstone terranes of the Appalachian Orogen and in the oceanic terranes of the Cordillera.

The greenstone-hosted quartz-carbonate vein deposits correspond to s ........

Summary:

The BAM gold resources occur close to the surface below a thin glacial till overburden, ranging from 10 – 15 m vertical thickness. The 2022 model was therefore constructed with a view towards selective open pit mining.

Geotechnical parameters used for the 2022 pit optimization work by Cube were based on recommendations from the geotechnical assessment work carried out by WSP in 2018 (Nelson, 2018).

Recommended Pit Wall Angles and Bench Height Based on Geotechnical Studies (Nelson, 2018):
- Bench Height - 20 m;
- Berm Width - 8.5 m;
- Batter Angle - 80 Degrees;
- Crest to Crest - 50 Degrees;
- Stack Height - 200 m;
- Ramp Width - 28 m;
- Ramp gradient - 1 in 10 ratio;
- Optimisation Slope - 54 Degrees;
- No Ramp Passes - 1;
- Number of Benches - 10;
- Horizontal distance - 148 m;
- Crest to Crest - 53.4 m.

The planned development of the open pits was scheduled based on the open pit optimization shells for Run B (Indicated and Inferred Resources). The schedule intervals are in quarterly increments for the life of the mine and includes a crusher feed schedule together with end of period stockpile balances.

The schedule was prepared within a schedule optimization tool (Minemax Scheduler) to obtain the maximum project value within the applied practical constraints. The schedule includes preproduction, mining production from the open pits, stockpiling and processing. To guide th ........
