2 The tailings backfill system, while part of the capex of a new mill, is something we can look at now and should result in considerable cost savings under our current production structure and continued use of the New Jersey Mill. We expect to begin discussing the economics/plans around an updated backfill system soon.

Nuclear power

Fuel is removed when the percentage of neutron absorbing atoms becomes so large that a chain reaction can no longer be sustained, typically three years. It is then cooled for several years in on-site spent fuel pools before being transferred to long term storage. The spent fuel, though low in volume, is high-level radioactive waste.

Effect of Tailings Properties on Paste backfill performance

15.10.20141 Introduction • The use of paste technology for underground backfill has been accepted as a cost-effectivealternative to rock and hydraulic backfill worldwide in the mining industry. Its using is extensive in Canadian underground hard rock mines and follows an increasing trend as well as in many parts of the world.

Making mining waste more sustainable

As such, many mines are moving to a more sustainable approach to disposal of waste rock through its re-placement underground as cemented paste backfill. Cemented paste backfill has the benefit of enabling a greater resource extraction. However, these benefits are not without their own engineering challenges!

Localised portions of the upper mine will be extracted using a bottom-up mechanised open stoping method with cement and unconsolidated rock backfill. All development has had 10%-15% overbreak applied, depending on drive type and location, as well as 100% mining recovery. All stoping has 0.5m hanging wall and 0.5m footwall dilution.

Backfill for stoping is generated from the development mining. The primary access drift is at Level 0, form where two internal ramps are driven; South and North which currently access down to the -95 m level. Mineral extraction from each level is via these main ramps directly to surface using rubber tired mechanized equipment.
