Pre-Production and Mine Plan
A pre-production period of two years would include construction of the electricity transmission line, upgrading and extension of current road access and mine site clearing, site infrastructure, processing facilities, and tailings starter dam construction.
The mine plan utilizes a conventional truck shovel open pit mining operation. Following the pre-production period, total material moved averages 15,000 tonnes/day.
Processing and Infrastructure
The Aley processing plant has been designed with a nominal capacity of 10,000 tonnes per day. The plant consists of single stage crushing followed by three stage grinding and a multi-stage flotation process to produce a Nb2O5 concentrate. The flotation concentrate is then processed in an on-site converter to produce FeNb as a saleable product.
Expected process recovery is 63% with annual production averaging 9 million kilograms of niobium over the mine life.
