Geostokos specialises in mineral resource and reserve estimation from pre-feasibility stage through to production grade control. In the 48 years since Geostokos was set up, we have provided expert advice on projects ranging from coal through base metals to gold, platinum and diamond applications.

Our involvement in projects ranges from the public statement of resources and reserves to stope valuation from face sampling. Our contribution may vary from review of work already carried out through to complete involvement in reserve estimation.

The statistical and geostatistical techniques used are equally applicable to many other spatial phenomena. Geostokos has been involved in environmentally oriented projects such as the storage of high level nuclear waste and the de-toxification of contaminated groundwater.
 

Geographically, we have been involved in deposits around the world, including the USA and Canada, the CIS, Australia, South America and Africa. In size, projects have varied from 100,000 to more than 2 billion tonnes.
