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.

Recovered conceptual route; complete prerequisites and flagship-quality capability are unverified.
Making outline
- Extract exposed native copper with stone tools, sort and transport acquired metal
- Research detailed preparation, operation and acceptance. Numerical limits and suitability are not specified.
What remains unresolved
- This route depends on suitable geography; oxide and sulfide ores need different processes.
- 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.
