Although Golden Star has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that future developments affecting the Company will be those anticipated by management. Please refer to the discussion of these and other factors in Management's Discussion and Analysis of financial condition and results of operations for the year ended December 31, 2020 and in our annual information form for the year ended December 31, 2020 as filed on SEDAR at www.sedar.com.
