Gladstone Manganese Project (Genesis 100%)
The Gladstone project is located approximately 15 kilometres west of Gladstone Shipping Port in Queensland. The project comprises one Exploration Permit (EPM 15771) which covers a total area of 24.35 sq km that is prospective for manganese and hosts several historic manganese mine/workings.
The Gladstone project hosts several northwest striking manganese ore deposits within the Doonside Formation. The deposits occur as structurally controlled lenses parallel to bedding in the enclosing sediments. There are six separate areas of manganese mineralisation located within the project area, the most significant of which is the historic Mount Millar manganese mine.
The Mount Millar mine opened in 1895 and operated intermittently until 1916 and then from 1958 to 1960. A total of 21,785 tonnes of ore was mined with a grade which ranged from 44% to 47% Mn%. The ore body at Mount Millar is lensoidal with the long axis running parallel to local bedding. It is approximately 70 metres long, 1 to 6 metres wide and mineralisation is reported to have exceeded 96 metres in depth. A small reconnaissance rock chip sampling over Mt Millar yielded high grade geochemical surface manganese assays in the order of 58.7%, 60.5% and 61.1% Mn.
