Metal mining support core custody records for AI
An outer container and an inner specimen can carry different identifiers.
NAICS 213114 · Support Activities for Metal Mining
An outer container and an inner specimen can carry different identifiers. USGS’s core collection and sampling resources provide context for preserving provenance. A support firm can create an offline exercise with dummy labels and an independently verified lab handoff. USGS core collection · USGS core sampling policy
Build a practice container card with two sample aliases and a fictional interval. Assign a verified receipt to one specimen and a similar receipt to a different container. Ask which custody link is supported and what would establish the remaining connection. Preserve interval, label and acceptance as distinct records.
Use no real core photos, depths tied to sites, exploration data, private lab results, client information or operations. Synthetic records are enough to show the task.
Original Fiund exercise
A container receipt does not prove receipt of every inner specimen
A fictional core-support handoff uses cardboard boxes and paper labels. Abstract interval marks do not correspond to boreholes or subsurface locations.
| Record | Source | What it records |
|---|---|---|
| MC1 | Practice container card BOX-R | Lists specimens R1, interval 1–2, and R2, interval 2–3. |
| MC2 | Receiver receipt | Confirms BOX-R and specimen R1 only. R2 count is not recorded. |
| MC3 | Separate receipt | Confirms specimen R2 in BOX-S, interval 8–9. No alias correction connects BOX-S to BOX-R. |
Question for the model
Which BOX-R specimen has a confirmed receipt, and does the second R2 label close the custody gap for interval 2–3?
Show the reference answer and checks
MC1 and MC2 support a confirmed receipt of R1 from BOX-R for interval 1–2. They establish that R2 was listed in BOX-R, but not that the receiver confirmed it. MC3's R2 belongs to BOX-S and interval 8–9. The repeated inner label alone cannot establish receipt of BOX-R's interval 2–3 specimen. That custody link remains unresolved.
- Marking every listed inner specimen received when only the outer box and R1 were checked.
- Joining duplicate inner labels across different containers and intervals.
Fields to preserve
- Outer container plus inner specimen key
- Makes the identity unique across reused short labels.
- Abstract interval
- Preserves which portion a receipt describes.
- Listed versus confirmed state
- Separates dispatch intent from receiver verification.
- Alias-correction authority
- Shows whether mismatched containers can legitimately be reconciled.
Test another case
Add a receiver photograph that shows both paper specimens but leaves their interval labels unreadable. Score visual presence separately from a verified interval-specific custody association.
Use dummy labels only. Do not include real core photos, drilling depths, exploration data, client records, lab results or site access information.

Describe the sources you control, the task they could support and what has already been checked. Use the existing-data assessment for an archive or the collection brief for a new recording project. The contributor agreement defines Fiund’s licensing authority and compensation. A guide or fictional exercise does not establish an accepted collection or a sale.
