Mineralization containing economically significant concentrations of Mg is known to occur in the ultramafic rocks which have undergone serpentinization. This rock type makes up the predominant lithology described at the Project, and occurs widespread. Lower concentrations of Mg within the serpentinite are present in dioritic intrusive rocks and lenses of andesite/gabbro.

Record Ridge will be mined using conventional open pit methods using a default 365 day production cycle comprising of one 12 hour shift delivering approximately 3,000 t/d of material to the crusher. Waste material below specified cut-off will be hauled from the pit and placed in a designated waste dump location.

Mill material will be mined from the pit and transported to the processing facility near the mine and placed in a stockpile and subsequently fed into the crusher bin by front-end-loader.

The mined magnesium oxide bearing material will be delivered to the comminution circuit. It will undergo primary crushing with a jaw crusher. The crushed materials will then be accumulated in storage for eventual grinding. Close circuit grinding will be undertaken with a SAG and ball mill system with interstage hydrocyclone classification to control energy use and product size. The ground material will then undergo liquid solid separation via thickening with water reclaim back to the comminution circuit. The ground solids will then be treated hydrometallurgically by leaching magnesium with sulfuric acid. The sulfuric acid will be produced on site by burning elemental sulfur. The majority of the heat from the acid plant will be reclaimed in the form of steam for use in the plant and also potentially as co generated electrical power as needed in the process. The leaching will be conducted in a series of continuous stirred tank reactors heated by steam produced from the acid plant. The le ........
