A big challenge in diamond mine development: Diamond price estimation (ONLINE)

Tuesday, June 28, 2022
Determining rock value at the feasibility stage for diamond projects is more difficult than for most other commodities. For most deposits, per tonne rock value is determined using the grade and published commodity prices. For diamonds, every deposit has different diamond characteristics and therefore a different average diamond price. Expensive bulk sampling programs yielding thousands of carats and associated statistical analyses are required to estimate the price accurately. The talks in the session will explore various elements of the price estimation process.
