This is the site of the Grande-Vallée aluminous clay deposit, which has a 1.04 billion tonnes Indicated Mineral Resource. For more information, see our Annual Information Form dated March 30, 2016 for the year ended December 31, 2015, specifically the section entitled “Description of the Grande-Vallée Mineral Property”.
An independent, NI 43-101 compliant geologist’s report by Jean-Guy Levaque, B.Sc.A., P.Eng. has confirmed the presence of a highly homogeneous aluminous clay deposit - an unusual and extensive rock formation - with an average grade of 23.13% alumina. The Marin sector is one of three significant sectors of clay minerals with high alumina content delineated on the site thus far. Following results obtained by Orbite’s pilot plant, these can now be referred to as “indicated resources.” Conservatively estimating a density of 2 tonnes per cubic metre, the indicated resource is approximately 1 billion tonnes on this site alone. Access to the surface ore is relatively easy, using conventional heavy mining equipment. There is no need for blasting. Orbite’s plant and properties are located near the biggest aluminum smelters in America.
