About Us

Derisk is an independent, privately-owned consulting company servicing the global minerals industry.  The company is new, but our directors and associates are “old hands” with a wealth of experience in exploration, mining, processing, environmental management, and social/community issues.

Our business strategy is straightforward and effective – We deliver Tier One services without the Tier One price tag because:

  1. We listen to your plans and provide options that meet your needs, then deliver to our agreed scope, schedule and budget.
  2. We ensure that our project team has comprehensive knowledge and the relevant expertise to deliver the appropriate advice and services for your scope of work.
  3. Our business model is based on a digital office-less structure, significantly reducing our business overheads.  We pass these cost savings directly to our clients.
