Meridian’s new Jaburi pilot plant in Espigão do Oeste, Rondônia, will begin its first phase of testing in September, checking mainly mechanical and electrical controls. In step with its project timeframe, the first ore load tests are expected to take place in early October, beginning a promising new step in the production of manganese by Meridian.

Designed with high-performance technology, the new Jaburi pilot plant will offer flexibility to process vein ores, as well as the colluvium manganese currently processed by the company.

This will give unlock greater quantities of the high-grade ore found on its 144,000 hectare mining tenement. The new Jaburi plant will offer Meridian an installed capacity of 50 tons per hour, eliminating all manual separation in the production process and providing significant savings in water and energy usage. In addition to the processing plant, Meridian has constructed two Australian-type water tanks with a capacity of 1 million litres each, ensuring seven days of full production autonomy reducing the plants demand for additional water resources.



In 2015 Meridian engaged Ausenco Engineering to evaluate the current plants with the mandate to improve technology, safety and productivity. With Ausenco expertise, Meridian was able to define a strategy to rebuild the Jaburi plant and improve the Rio Madeira plant.

MERIDIAN engaged Küttner Engineering, a German company with long experience in Brazil, and its partner Allmineral a mining process and technology solutions provider, to provide a turn-key solution for the refurbishment of Jaburi. With new technology, Jaburi is now able to process both colluvium and the vein materials, giving it the flexibility to optimise its recovery of high grade manganese. The construction started in early April, and has meet every phase of its planned schedule
