Native copper deposit
Locate and screen exposed copper-bearing geology; no site assumed; open discovery hypothesis, unknown caller demands and complete inventory.
Discovered · unresearchedClosure: OpenInventory incomplete
Capability requirements and tolerances
Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.

Making outline
- Locate and screen exposed copper-bearing geology; no site assumed
- Research detailed preparation, operation and acceptance. Numerical limits and suitability are not specified.
What remains unresolved
- Deposit access, exposure and suitability at the chosen location are unverified.
- Exact grades, quantities, operating parameters, tolerances and complete making dependencies are not finalized.
- Candidate method, complete inventory, caller demands and physical compatibility require research and review.
