mineral processing of narrow steeply dipping veins

Mechanical excavation systems (in three parts) 1. Drill

The concepts for the two drillsplit mechanical excavation mining systems presented are (1) a method for steeply dipping narrow veins 0.6 to 1.2 m wide and (2) a longwall method for flatlying tabular ores. In the proposed systems, 70 to 80 pct of the ore is disposed of underground as backfill.

The North Quartz zone is 1050 metres northeast of the A vein and consists of steeply dipping quartz veins with westnorthwest strikes exposed over an area of 100 by 300 metres at the head of a cirque. Drilling in 1987 intersected narrow (less than 1 metre) quartz veins containing disseminated pyrite, galena and sphalerite.

The two veins have a combined strike length of over 1,500 metres. The NC2 vein is the most important source of sulphide silver mineralization and contains approximately 30% of the mineral resource and reserve ounces of silver. It is a narrow, one to seven metre wide mainly sulphide and partly oxide vein with a strike length of over 900 metres.
