Company Overview and Business Model

Derisk is an independent, privately-owned consulting company servicing the global minerals industry.  Our directors, staff and associates have a wealth of experience in exploration, mining, processing, environmental management, and social/community engagement.

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, a small core team of staff, and an extensive associate base of trusted and experienced mining consultants. This model significantly reduces our business overheads and we pass these cost savings directly to our clients.


Derisk provides advice and services to exploration, mining, advisory, corporate finance, private equity, legal, and regulatory organisations.  Our services encompass the full mining value chain from exploration, assessment and feasibility, planning, construction, production, to closure and rehabilitation i.e.:

  • Due diligence, reviews, and audits. We perform internal and external technical reviews and audits to support transactions, continuous improvement, and compliance obligations.  We can review projects at any stage of development, from early exploration through to mature operations.  Our reviews can be desktop or site-based depending on your requirements.
  • Expert/Specialist reports and public reporting. If you need a Competent/Qualified Person report to support a listing or reverse takeover, a technical assessment report, or a mineral asset valuation prepared in accordance with international reporting standards/codes such as the JORC Code(1) and the VALMIN Code(2), Derisk can assist. We also undertake compliance checks of internal and third-party reports prepared for stock/securities exchange release.
  • Resource/Reserve estimation and studies. Our staff and associates have the expertise to prepare and report Mineral Resource and Ore Reserve estimates for a diverse range of commodities, geological settings, and mining methods.  We can also undertake technical studies at a scoping and prefeasibility level, as well as provide technical support in preparing feasibility studies.
  • Exploration and mine operations support. Derisk can support your exploration and operations across geology, mining, and metallurgy.  If you need assistance in planning and executing exploration programs, or support in grade control, resource estimation, mine planning and scheduling, reserve estimation, process control or reconciliation, we can assist.
  • Strategic/organisational planning and management reviews. How many times do you see companies reinventing the wheel, when it comes to strategic technical planning, organisational structure, workflows, management and operational planning, and the like. Derisk staff can provide objective input into your strategic planning processes.
  • Technical opportunity and risk assessment. Mining is perceived as a “risky business”. As our company name implies, we are focused on providing advice and services that minimise technical risk and maximise the opportunities associated with better mining and processing of your mineral asset.
  • Geological database management. Whether you need short- or long-term support to help manage your geological databases or have specific project requirements, we can assist you. Derisk provides support via a range of software applications, including QA/QC protocols and compliance checking.
  • Mentoring and professional development. We provide tailored one-to-one mentoring of early-mid career technical staff and have a range of mentors that can assist you to reach your full potential as a mining industry professional.  We also deliver customised professional development workshops that cater for technical and management staff, which can be site-based or capital city-based.

Derisk has Associates based around the world that often minimises the need for international travel.  Nevertheless, Derisk staff and associates do travel the world.  As part of our risk management process for site visits, we monitor travel advice, and in the case of a travel warning, we will review the travel (including any risk-mitigation measures) and reserve the right to decline travel to any destination where a travel warning is in force.
