Limits of our service
We do not issue mineral reserve certifications. Reserves are certified by registered mining engineers and regulatory bodies (Brazilian ANM, JORC/NI 43-101 in formal projects). Our work supports — does not replace — the responsible engineer or geologist.
We do not perform ICP-MS in-house. Coordination with qualified partner laboratories.
We do not provide full legal validation. Documentary review is basic, focused on existence and identification. Full legal review remains with the buyer's counsel.
/ FAQ — due diligence
Frequently asked questions
Do you issue official mineral reserve certifications?
No. Reserves are certified by registered mining engineers and regulatory bodies (Brazilian ANM; JORC or NI 43-101 in formal projects). Our work supports — does not replace — the responsible engineer or geologist.
What exactly is included in field verification?
On-site visit, physical confirmation of the declared material, geo-tagged photos, recording of operational context and basic identification of the seller. When the matrix allows, preliminary XRF read on site before commissioning destructive assay.
Can I request only sampling, without the rest?
Yes. The service is modular. Some operations only need protocol-based collection with chain of custody for shipment to the buyer's lab. Others want the full package. We quote by scope.
Do you fully validate the seller and operation legality?
No. Documentary review is basic — focused on existence and identification. Full legal validation, regulatory due diligence, mining licence verification and tax matters remain with the buyer's counsel.
Timeline for the report?
For a simple visit without long travel: preliminary report in a few business days. For operations with sampling and partner-lab assay: depends on the laboratory queue (typically 1–3 weeks for fire assay/ICP-MS).
Is the report suitable for presenting to investors or internal committee?
It is a bilingual PT/EN technical field report, with photos, readings and assay where applicable. Several buyers use it as input for their internal material; the financial interpretation and investment decision remain with the client.
Do you cover any region in Brazil?
Yes. CATPRO serves all of Brazil, and sellers ship with a prepaid label issued by CATPRO. For larger projects, we mobilise a visit anywhere in the country with agreed timeline.
