Technical Due Diligence

Will it work, and will it keep working?

We examine the technical basis of a mine, plant or project from the evidence behind it, and tell you which claims hold, which are conditional and which cannot be confirmed. You choose how deep to go: a fixed-scope desk review, or a full due diligence with a site visit.

Choose how deep to go

Desk review

Fixed scope: a written opinion on a study or plan.

What we look at

  • Whether the method suits the question
  • Data quality, sources and how they are used
  • The assumptions, and which ones drive the result
  • Whether the conclusions follow from the evidence
  • Gaps, inconsistencies and claims that are not supported
  • Any relationship between the reviewer and the work that should be disclosed

What you receive

  • A written opinion on the study or plan
  • Findings ranked by how much they matter
  • A list of corrections and open questions
  • A statement of the reviewer’s independence

Full due diligence

A site visit, all areas, plus operating economics and flip points.

What we look at

  • A site visit, and the plant’s real condition and capacity
  • All technical areas: process route and flowsheet, feed and mineralogy, power, water, reagents and logistics
  • Rights, permits and the conditions still to be met
  • Operating economics: what it costs to run and what it earns
  • Flip points: the price, tariff, volume or feed cost at which the economics turn from working to not working
  • The main technical risks, and the stop conditions that would end the project

What you receive

  • A written findings report
  • A risk register that ranks the issues by consequence
  • An operating-economics summary with its flip points
  • Each claim marked by how well it is evidenced

Who it is for

  • Investors and acquirers
  • Lenders and development finance institutions
  • Boards and project sponsors, and authors who want their own study checked before it is published

Scope, fees and timing are agreed in writing before any work starts.
