During the year ended August 31, 2012, the Company acquired a closed-loop solvent based oil extraction technology which facilitates the extraction of oil from a wide range of bituminous sands and other hydrocarbon sediments. The Company has filed patents for this technology in the USA, Russia and Canada and has employed it in its oil extraction plant. The Company commenced partial production from its oil extraction plant on September 1, 2015 and was amortizing the cost of the technology over fifteen years, the expected life of the oil extraction plant. Since the Company has substantially completed the increase in capacity of the plant to 1,000 barrels during fiscal 2018, and expects to further expand the capacity to an additional 3,000 daily, it determined that a more appropriate basis for the amortization of the technology is the units of production at the plant after commercial production resumes. No amortization of the technology was recorded during the three and nine months ended May 31, 2019 and for the 2018 fiscal year.
