For cooperatives and concession holders
You hold the licence. Let’s work the deposit properly, together.
BYM partners with the cooperatives and associations that already hold mineral concessions in the Democratic Republic of Congo. We bring equipment, supervision, standards and buyers; you keep your licence, your members’ place and what you learn.

Who this is for
Three kinds of partner.
- 01
Mining cooperatives
Licensed cooperatives (coopératives minières) with an exploitation permit and members already working the deposit.
- 02
Exploitation associations
Artisanal exploitation associations recognised under the DRC Mining Code, with a defined area and leadership.
- 03
Concession holders
Holders of a permit over a mineral deposit — gold today, other minerals as permits allow — looking for a partner to work it properly.
The exchange
What BYM brings. What you keep.
BYM brings
Equipment
Hydraulic pumps and water lines, sluices, excavators, loaders and vehicles, delivered to site and maintained there by BYM technicians.
Supervision and maintenance
A site lead and a maintenance team on the ground, working alongside the cooperative’s own leadership.
Safety, health and environmental standards
Safety briefings every shift, protective equipment, water and sediment management, fuel containment and progressive rehabilitation.
Training
Operator training on equipment and processing, first aid and safety, record-keeping — skills that stay with the cooperative’s members.
Documented weighing and chain of custody
Every batch weighed on a precision balance and recorded, so both parties see the same figures.
Buyers and administration
Access to buyers at transparent, reference-based prices, and help with permits, reporting and compliance under the Mining Code.
You keep
Your licence
The permit stays in the cooperative’s name. BYM does not acquire it and does not need to.
Your members’ place
Members keep working the site, with better tools and conditions. The partnership is designed to employ, not to displace.
Your standing
The cooperative remains the counterpart of the community, the chefferie and the provincial mining authorities.
A written share of production
How production is shared is set out in the agreement before any equipment moves, and reconciled against the weighing records.
What you learn
Trained operators, documented processes and a track record that belong to the cooperative, whatever happens next.

How it starts
Five steps from a first message to a working site.
- 01
Write to us
Tell us who holds the licence, where the site is, what is mined and how it is worked today. French or English.
- 02
Visit and assessment
BYM visits the site, reviews the permit documents and the workings, and discusses what the deposit and the terrain need.
- 03
Agreement
A written partnership agreement covering governance, compliance, safety obligations, equipment and how production is shared.
- 04
Mobilisation
Equipment is brought to site, the team is trained, water and safety systems are set up, and work starts.
- 05
Operation together
Joint oversight, weighing records shared with the cooperative, regular reviews and progressive rehabilitation of worked ground.
What we ask
Conditions every partnership meets.
- 01
A valid exploitation permit or recognised artisanal zone, with documents BYM can review.
- 02
A cooperative or association with recognised leadership able to sign and honour an agreement.
- 03
Willingness to adopt safety rules on site, including protective equipment and safety briefings.
- 04
Operations that meet responsible-sourcing conditions: no involvement of armed groups, no child labour, no forced labour, in line with OECD due-diligence guidance.
- 05
Openness to documented weighing and shared records.
