Independent. No equity in the projects we review, no ties to equipment vendors.
Compliant. Qualified and Competent Persons on staff for S-K 1300, NI 43-101 and JORC disclosure.

How we work
We audit what exists before creating anything new: databases, models, test work, permits, cost history. Gaps are flagged early.
01 — Scope
A 30-minute call to understand the decision you face, the data you hold and your deadline. You get a fixed-fee proposal within days.
02 — Review
Our Qualified Persons sign what they write, and stay available through audits, financings and regulator questions.
03 — Deliver
Models, schedules and reports built to disclosure standard, with working files handed over so your team is never locked in.
04 — Stand behind it
“Good mines are not found. They are made, one defensible assumption at a time.”
— Working principle, TerraMine Management LLC
