Håkansboda copper project – technical study & mine planning
When you are evaluating a historic copper project with both open-pit and underground potential, you need more than legacy data. You need an independent view of the mineral resources and a realistic mining concept that can support a Scoping Study or mining PEA in line with modern reporting standards. The Håkansboda copper project in Sweden combines near-surface and underground mineralisation in a brownfield setting. For a preliminary assessment, you want to understand how much of that mineralisation can be converted into a JORC-compatible mineral resource and what a practical mine plan could look like over the first years of operation.
Client & context
If you are responsible for a project like Håkansboda, you are typically working with:
- Historic mine records and drillholes of varying quality and spacing.
- Both open-pit and underground possibilities around old workings.
- Expectations from investors and regulators for a transparent, JORC-aligned technical study.
At Scoping Study level, you want an independent check of the mineral resource estimation and a high-level mine plan that shows how copper (and other base metals, if present) could be extracted safely and economically.
Challenge
On a project like Håkansboda, you face several questions:
- Is the mineral resource estimation consistent and robust enough to support a JORC Scoping Study?
- How do open-pit and underground options fit together in one development concept?
- What kind of mine design and schedule would be realistic for a first-pass economic assessment?
You need a controlled, well-documented approach to resource estimation and mine planning so that the preliminary economic assessment reflects the real potential of the deposit, not just optimistic assumptions.
Approach
The technical work for the Håkansboda copper project was structured to give you a clear line from geological data to mining plan.
Independent control of mineral resource estimation
You get an independent review and control of the mineral resource estimation for both the open-pit and underground parts of the project. The focus is on:
- Validating and interpreting available geological and assay data.
- Checking domains, interpolation parameters and classification criteria.
- Ensuring that the reported mineral resources are compatible with JORC Scoping Study expectations.
Mine planning, design and scheduling
Based on the controlled mineral resource model, you get a preliminary mine plan that covers:
- Open-pit and underground layouts for copper and other base metals.
- Conceptual access, development, stoping and backfill strategies where relevant.
- High-level mine scheduling to show production profiles over the assessment period.
The planning work is kept at Scoping Study level, so you see the main options and trade-offs without pretending to know every detail. The result is a mining concept that can feed into a preliminary economic assessment (mining PEA) for base metals.
Results & value
From this type of work on Håkansboda, you gain:
- A controlled, clearly documented mineral resource estimation for the open-pit and underground copper project.
- A JORC Scoping Study level mine plan, design and schedule that makes it easier to communicate project potential to investors and regulators.
- A more realistic view of how a combined open-pit and underground development could look in the early years of the project.
For you, this means a stronger technical foundation for deciding whether to invest in further drilling, more detailed engineering or formal economic studies.
If you are evaluating a historic or brownfield copper project with open-pit and underground potential and want independent resource control and Scoping Study level mine planning, you can turn to Gosselin Mining. You get a realistic, JORC-style mining concept that helps you decide your next step.
