Formatted abstract
 The dramatic increases in metal prices across the board in the last few years have allowed the opportunity for many deposits to be economically exploited. One subset of deposits in particular to which this applies are narrow vein flat dipping ore bodies. These ore bodies pose significant challenges in that they can be very irregular in many aspects including: grade, thickness, dip, and strike. Despite this some of these deposits contain very high grade ore over large areas and thus represent a large resource. Due to the ever diminishing cheap open cut reserves underground deposits are becoming more attractive.

This research project aims to investigate the current state of mining narrow vein deposits in Australia through a sample of four case studies. These case studies are: Bullen, Warrior, Darlot and Dry River South. Through examining the mining method, mine design and production as well as financial outcomes these sites are benchmarked.

It was found that the current methods being employed at narrow vein deposits are effective in the current climate. Should the market take a fall many of these mines may be jeopardised as a result of marginal economics. Mining cash costs can account for up to 70 % of total cash cost at small scale underground deposits and therefore increases in the productivity or more effective mine designs and methods can have massive effects on profitability.

It was found that currently within Australia there is a distinct lack of specialisation in this area of underground hard rock mining. Particularly the equipment dealers and consultants do not exist to provide adequate support to these mines. This can be a discouraging factor for any company to undertake a venture even in a promising deposit.
