Supply-system-level aggregation of structurally constrained mineral resources: A framework for vein graphite

Vein graphite deposits contain exceptionally high-purity graphite but remain minor contributors to global supply because their narrow, discontinuous, and structurally controlled geometry limits conventional approaches to scaling production. This paper argues that the principal constraint on vein graphite development is not resource quality, but supply-system design. Using vein graphite as a case study, a supply-system-level aggregation framework is proposed in which multiple distributed mining operations are integrated through centralized processing, quality management, logistics, and traceability systems. The framework demonstrates how coordination across operations can transform fragmented production into consistent, specification-compliant supply capable of meeting modern market requirements. The analysis further examines governance, market access, resource integration, and circular economy considerations that influence implementation. While developed for vein graphite, the framework is applicable to a broader class of structurally constrained and distributed mineral resources. The results suggest that supply-chain participation increasingly depends on supply-system integration and institutional coordination as much as on geological endowment.
