A mineral exploration company, Galileo Mining Ltd (ASX:GAL) provided an update on the progress of the Norseman Cobalt Project Scoping Study.
SGS-Bateman has concluded a scoping study level process plant design with CAPEX and OPEX estimates for the proposed processing plant. SGS is the company which offers business solutions to enhance quality, safety and productivity etc. of a business, which assists its clients to navigate an increasingly regulated world.
The designing and an estimated cost of the processing plant has been given to CSA Global. At present, CSA Global is finalising a Conceptual Mining Study based on flow sheets provided by SGS-Bateman.
SGS Bateman has completed a Process Plant Scoping Study based on an atmospheric leaching plant which treats beneficiated material. The proposed plant is designed to treat 254 tonnes per hour (2 Mtpa) of laterite ore which delivers 152 tonnes per hour (1.0 Mtpa) of beneficiated ore to the leach processing plant.
CSA Global offers strategic mining services and advice to the organizations involved with the global mining industry. It is a mining, geological and management consulting company.
The beneficiation and leach test work reported in the previous study results have been combined in the study. A 24-hour leach residence time was utilized in the process design work. The optimisation of leach residence times might help in decreasing the time required to reach economic metal extraction at reduced consumption rates. Initial test work results suggest that a cobalt upgrade of over 200% can be achieved, with a mass reduction of approximately 70% as opposed to the much more conservative optimisation study assumptions which use a 60% cobalt increase associated with a 50% mass reduction. An ongoing program of concentration test work is planned to assist in the optimisation of concentrate sizing.
The Preliminary beneficiation results from Norseman samples showed a significant increase in cobalt grade using commercially available sizing techniques. For the scoping studyâs purpose, a conservative beneficiation assumption is made, where the coarse and medium portions of the samples were combined to result in a 60% increase in cobalt grade and 15% increase in nickel grade, accompanied by an overall mass reduction of 50%. Based on these assumptions, the recovery of total cobalt from the beneficiation plant is calculated to be 80% and 57.5% for nickel.
The early results of work on optimisation reflect nickel mineralisation at the Mt Thirsty deposit, outside of the present JORC (Australian Code for the Reporting of Exploration Results, Mineral Resources and Ore Reserves) compliant cobalt resource. The present JORC is based on a 0.06% cobalt cut-off which excludes nickel mineralisation with lower levels of cobalt. For the inclusion of further nickel mineralisation in the Conceptual Mining Study, GAL has an intention to conclude a fresh JORC estimation of the Mt Thirsty deposit using a suitable nickel cut-off grade which will capture both the nickel and cobalt mineralisation.
Recently, the company updated the market about its Fraser Lanternâs Prospect maiden drilling results.
The stock of the company traded flat during the trading session and stood at A$0.165 (as on 19 March 2019).
