[Ferro-Alloys.com] New Age Exploration (ASX:NAE) reported results of further technical studies on its Redmoor Tungsten-tin project in Cornwall, UK. The company has previously completed an updated inferred mineral resource estimate and exploration target for the project.

 

As quoted in the press release:

 

A preliminary mining study was recently completed by technical consultants, Mining One. The study included stope optimisation, high level underground mine design and high level capital and operating costs estimates for a bulk mining option and a high grade mining option. High level mine designs for both options included a simple decline, sumps, stockpiles, ventilation system, escape way and ore access along with a crown pillar from the surface to prevent surface subsidence. The following assumptions were used for both options:

 

1.5m minimum stope width / 25m max stope width

15m level spacing between development roadways

10% stope mining dilution, 90% stope mining recovery

The underground mining method assumed in the study is bench stoping with backfill (rock fill in conjunction with a form of cemented fill where required).
