Mining Feasibility Studies In Australia & Internationally

Practical Studies For Mining And Mineral Processing Projects

Como Engineers delivers mining feasibility studies that give project owners clear technical and financial grounds for their decisions. From early scoping studies in Australia and internationally, through to pre-feasibility and feasibility studies, we provide practical, experience-led guidance for mining and mineral processing projects.

From Scoping To Bankable Feasibility

Whether it is a gold mine feasibility study or a complex polymetallic project, Como Engineers tailors each study to your geology, processing requirements and commercial objectives.

Como Engineers has experience in commodities, including:

Gold
Silver
Copper
Zinc
Lead

Nickel
Critical Battery Minerals
Lithium
High Purity Aluminium (HPA)

Scoping Studies

As an established provider of scoping studies in Australia, we help owners decide whether a deposit warrants further investment.

Our scoping studies give an early-stage assessment of technical options, CAPEX and OPEX, typically to ±30–50% accuracy and delivered based on the developed process flowsheets, design criteria and equipment lists.

Pre-Feasibility Studies

Our pre-feasibility studies build on the scoping phase, expanding metallurgical testwork detail and evaluating flowsheet viability. Como Engineers use this stage to narrow technical risk and tighten cost confidence, typically to ±25–30% accuracy.

Feasibility & Bankable Studies

Como Engineers feasibility studies finalise the process flowsheet, complete detailed metallurgical testwork, and define CAPEX and OPEX to ±10–15% accuracy. This is the level of rigour needed to support financing, board approvals and final investment decisions.

Engineering Studies

After the feasibility phase, our engineering studies advance the design to a construction-ready level. Through front-end engineering design (FEED) and early contractor involvement (ECI), we produce full tender packages, allowing clients to secure fixed-price submissions at ±5–10% cost accuracy.

Optimisation Studies

For operating plants, our optimisation studies identify bottlenecks and inefficiencies across the circuit. Our team of metallurgists audit the full process to recommend changes that lift recovery, reduce operating costs and increase throughput.

Our Projects

Support Beyond The Study Phase

As experienced feasibility study consultants with full in-house engineering, Como Engineers can take your project well beyond the study phase. Our feasibility study consulting services are backed by integrated, end-to-end delivery, so there is no need to re-brief a new team when it is time to build.

Our wider services include:

Detailed engineering design and drafting

Procurement and construction management

Modular and transportable plant design and fabrication

Plant relocations, refurbishments, expansions and upgrades

Commissioning and operational support

This continuity carries the knowledge gained during your study through to delivery, reducing risk and protecting schedules.

Frequently Asked Questions

What level of study accuracy can I expect?

Accuracy depends on the study level:

Scoping ±30–50%
Pre-feasibility ±25–30%
Feasibility ±10–15%
Engineering studies ±5–10%.

What commodities do you work with?

Whilst we are known as experts in gold processing, we have extensive experience across gold, silver, copper, zinc, lead, nickel, critical battery minerals, lithium, and high-purity aluminium (HPA).

How long does a mining feasibility study take?

It depends on the study type and project complexity. A scoping study may take a few weeks; a feasibility study can take several months. We prepare and agree on a realistic project schedule with you at the outset.

Do you only work in Australia?

No. Como Engineers supports projects in Australia, Indonesia and other international markets, having supplied to 30+ countries across 6 continents.
