Ability to operate existing resources, acquire them and utilize economically attractive coal resources at a competitive cost

Resources may not be available when they are needed or if they are available their extraction at a competitive cost in a given period may not be plausible. The Group may not be able to assess the geological structure of deposits precisely in forward-looking regions, which may adversely affect its profitability and financial position if this assessment proves to be erroneous. Moreover, the investment, acquisition and exploration projects planned by the Group may not provide additional material resources or the operation of these resources may not be profitable.
