In a March 1, 2018 press release Manganese X Energy Corp. reported on efforts to understand the mineralogical composition of the manganese bearing zone at the Battery Hill deposit near Woodstock, in west-central New Brunswick. The results showed that the deposit contains several manganese minerals ranging from complex carbonates to silicates, and that the total manganese bearing mineral assemblage represented up to 50% of the ore mass in some cases. An extraction testing program showed high manganese extraction levels (up to 96%) with variable iron and alkali metal solubility levels. The company is working on further metallurgical testing to develop processing methods to upgrade the ores.
