What is the difference between resource and reserve?
Mineral Resource is the total estimated mineral in-ground (Inferred/Indicated/Measured). Mineral Reserve is the economic part (Probable/Proven) — planned to be mined. Reserve ≤ Resource always.
What is metallurgical recovery?
Recovery is the % of metal/mineral in the ore that ends up in the final product after processing. Loss occurs due to fines, tailings and process inefficiencies. Iron ore typically 78–92%, coal 85–95%.
What is head grade and why does it matter?
Head grade is the concentration of valuable mineral in the ore fed to the processing plant. Higher grade = less ore to mine per tonne of product = lower cost. Grade significantly drives project economics.
