Mining Project Assumptions Log
This is a practical guide to building a assumptions log for a mining project project — a register of the assumptions the plan depends on, to be validated, adapted to the realities of developing a mine or mineral extraction operation.
What a Assumptions Log is
A assumptions log is a register of the assumptions the plan depends on, to be validated. For the full concept and how it works in general, see Project Assumption. On a mining project project it plays the same role, tuned to this kind of work.
Why it matters for a Mining Project project
Mining Project projects live or die on developing a mine or mineral extraction operation. A well-built assumptions log gives the team a shared, explicit reference for exactly that — reducing ambiguity, aligning stakeholders, and making problems visible early enough to act. Skipping it, or doing it generically, is how mining project projects drift into avoidable delay and cost.
What to include
- Assumption
- Impact if wrong
- Owner
- Validation status
Mining Project-specific considerations
Tailor the assumptions log to the risks that most often derail mining project projects:
- Environmental and community risk
- Geological uncertainty
- Remote-site logistics
Example
On a real mining project project, the assumptions log would be shaped by developing a mine or mineral extraction operation. In particular, it should explicitly account for the project’s biggest risks — environmental and community risk, geological uncertainty, remote-site logistics — rather than treating them as afterthoughts.
