Simulus Engineers will complete the initial study into the hydrometallurgical plant design.
This work will assess the commercial and engineering parameters around the scale-up of the hydrometallurgical flowsheet.
Study of manganese markets
Metal Bulletin will provide a study of the high purity manganese markets including price and volume assessments taking into account current trends and projected future trends.
This study will look at EMM, EMD and manganese sulphate for lithium-ion batteries.
In late 2017 Montezuma advised that test work on the hydrometallurgical processing of Butcherbird ores had exceeded expectations and achieved the required specification to produce high purity manganese products.
Work is part of scoping study
Last month the company announced the start of a scoping study into the production of high purity manganese using the innovative hydrometallurgical processing route it developed in conjunction with CSIRO.
The scoping study is expected to take up to six months to complete and if it delivers positive results, Montezuma will consider a decision to proceed to a preliminary feasibility study.
Strong markets for lithium-ion battery materials
Montezuma aims to take advantage of strong commodity market conditions, particularly relating to metals required for lithium-ion batteries, including high purity manganese.
Butcherbird has a total resource of 180.8 million tonnes at 10.8% manganese with 22.5 million tonnes at 12% manganese in the indicated category.
