The revision process to draw up a feasibility study for Globe Metals & Mining’s Kanyika niobium project in Malawi has been finalised.
The company says that is has also obtained updated capital and operating cost estimates through a tender process undertaken independent of Globe, using the results to update its financial model.
Expectations are that mill feed production will ramp up from one million tonnes per annum (mtpa) in the first year to 1.5mtpa from the second year.
The final pit dimensions at Kanyika are expected to be 250m wide, 2.2km long and an on average about 130m deep. Mining will involve conventional open pit methods to extract ore from several open pits along a single longitudinal strike.
The mine production schedule, prepared by Orelogy Mining Consultants, details the treatment of high-grade material initially to improve project economics and the stockpiling of lower-grade material. The schedule assumes Kanyika’s resource will be mined in a series of stages.
Processing will involve conventional crushing, grinding, desliming and magnetic separation before pre-flotation and pyrochlore flotation to produce a pyrochlore concentrate.
