Abstract
The mining industry is not as favourable investment destination as in the past. It is getting
more challenging to raise capital for a mining greenfield project with compared to other
investments that have relatively higher returns in shorter time with less risk.
Mining companies need to focus on sustaining or expanding existing operations with
additional brownfield projects. The main advantages of a brownfields project are the lower
risk in the resource, and the lower capital and operational cost resulting from the synergies
with the existing operation.
Establishing another operation within an existing mine, creates new set of challenges.
Geological and geotechnical factors have a big impact of placement of infrastructure. There
is always the risk that the available areas were not utilised for a reason. A good understanding
of the ground conditions of these areas is required. There is also the challenge of establishing
the new infrastructure next to or close to existing in of establishing new infrastructure close
to existing infrastructure.
This challenge can be alleviated by careful, detailed planning of the position, design and
establishment of the new infrastructure.
The most important principle is to gather as much information as possible from all the critical
factors that can influence the establishment of the new operation. This information must be
studied and understood to create detailed designs. The detailed designs must take into
consideration all possible flaws and must be engineered not to fail. A phased approach to
implementation is necessary to break processes up into more manageable sections.

To attract shareholders to their mining projects companies need to focus on reducing the
required capital, risk, and the return period of invested capital. This can be achieved exploring
for brownfields opportunities within their own realm. Even if the resource was thought to be
unfeasible the synergies that can be established between the potential project and the
existing mine can be of such a big influence on the capital and operation expenses that it can
be turned viable.
