Continuous production of bacteria for leaching metallic ore is carried out by inoculating the bacteria on a pitted plate, supplying a nutrient substrate to the bacteria to promote growth of the bacteria, periodically harvesting bacteria from the plate and conveying the harvested bacteria by sluice to a leaching site. Harvesting is preferably carried out by passing a blade over the plate to shear off bacteria above the surface of the plate leaving behind bacteria within the pits of the plate for continued bacteria growth.
