Desk methodology
How we verify a claim.
Every listing on DealRoom carries a verification tier. The tier says how far the desk has gone — no further, and no less. This is the methodology those badges are read against, published in full so you can judge a listing before you spend anything on it.
The four tiers
A tier is a statement about paperwork and observation, not about whether an asset is a good deal. A Tier 3 claim can be poor ground and a Tier 0 claim can be excellent — the tier only tells you how much of what you have been told the desk has actually confirmed.
- Tier 0 · Unverified
Unverified
Listed by the holder. No desk checks performed yet.
What the desk has done
- The holder's own description is recorded as given.
- Nothing is published that the desk knows to be false.
What it still does not mean
No document has been sighted. Treat everything on the listing as a claim made by the seller.
- Tier 1 · Documents sighted
Documents sighted
Title and permit documents have been sighted by the desk.
What the desk has done
- Title and permit documents have been sighted by the desk.
- The document names, numbers and dates are checked for internal consistency against the listing.
What it still does not mean
The documents have not yet been checked against the public registry, so the desk cannot confirm they are current.
- Tier 2 · Desk verified
Desk verified
Documents cross-checked against public registries by the desk.
What the desk has done
- Everything at Tier 1.
- Title details cross-checked against the Mining Cadastre and other public registries.
- The registered holder matches the party offering the asset, or the chain to them is documented.
What it still does not mean
Nobody from the desk has stood on the ground. Grades, tonnages and workings remain as reported by the holder.
- Tier 3 · Site verified
Site verified
Desk has completed a site visit and technical review.
What the desk has done
- Everything at Tier 2.
- A desk representative has visited the site.
- Workings, access and the physical extent of the claim have been observed and photographed, and a technical review completed.
What it still does not mean
A site visit is not a resource estimate. Tonnage and grade still require your own competent-person work.
Rules that apply at every tier
A tier can go down
If the documents behind a listing change — added, replaced or removed — its tier drops to Tier 0 automatically and stays there until the desk checks the new paperwork. Verification describes the documents the desk actually saw, so it cannot survive them being swapped.
Verification is not an audit
The desk is not a competent person, a valuer, or a certifying authority, and none of this replaces your own due diligence. A tier is a desk assessment: what we looked at, and how closely.
Figures stay the holder’s
Grades, tonnages and strike lengths on a listing are as reported by the holder unless a listing says otherwise. They are not resource or reserve statements at any tier, including Tier 3.
What stays private until NDA
Exact locality and coordinates, the guide price, and the title and technical documents are held by the desk and released once your NDA is executed and you have been qualified. The public teaser is deliberately coarse.
Ask what tier a claim is, and what it would take to raise it.
A real person will tell you what is on file before you sign anything. No account needed.
