Coal & Minerals



A geological survey represents the starting point in determining the feasibility of any potential coal or mineral mine site. Geological survey that are based on sound and established survey standards and practices ensure that our client receive realistic and factual information that will provide them with the right information that ultimately will assist them in their investment decisions.

The trading of commodities on an international basis represents an important facet of today’s globalised company. Inspection and superintending services play a key role in ensuring that the financial and legal interests of both the buyer and seller to any commodity transaction are preserved.
