For miners and producers
You prove it once. Then twenty buyers ask again
A mine site carries the heaviest evidence load in the chain. You are audited against a standard, then every customer asks for the same thing in their own format, and then a lender asks again.
30 minutes on your own supply chain, with someone who has done this job.
What lands on your desk
The same evidence, asked for four different ways
Site certification
IRMA, Copper Mark, and CMSI when it lands. Audited by a third party, with the result published.
Buyer questionnaires
Arriving all year, each in a different shape, asking for what the audit already covered.
Lender and investor diligence
The same evidence again, reshaped for people who fund the operation.
Your own internal standards
Often more demanding than the external ones, and applied across many sites.
What you do with beSirius
One Twin, then every job runs off it
Proof
The standards overlap more than they admit. Copper Mark recognises an IRMA audit at 50 and above, and one water management plan can serve three schemes at once.
