As of the First <br />Quarter 2010, water inflow is estimated based on the approximate water elevation and the void volume of the mine workings. <br />(2) Access to the mine was temporarily restricted as of the third quarter 2012. Inflow rate measurements will be resumed when the portal is reopened. <br />
