145 <br />1 was published, and then it got significantly better, <br />2 and now look where it is. 2007-2008, another mine <br />3 flooding strategy that's failed. <br />4 Here's five more. The operator has <br />5 mentioned the Dinero Tunnel. We don't even have any <br />6 water quality data yet, so how can we assess if it's <br />7 been a successful remediation strategy in terms of <br />8 geochemical stabilization? <br />9 This last one, this is another sample <br />10 that the operator provided. The Iglesias District, <br />11 Monteponi, Sardinia. This is primarily metal <br />12 cations in a carbonate system. It's not a very <br />13 appropriate analog for Schwartzwalder. The <br />14 attenuation is inconsistent. Where I've marked with <br />15 arrows are some data that looks like it's not really <br />16 being attenuated. It is actually either flattening <br />17 or slightly increasing. The majority of them are <br />18 showing that. <br />19 The operator has said that dewatering <br />20 poses substantial physical feasibility challenges in <br />21 installing a pump, pipe, or other equipment into the <br />22 mine. Setting a pump at 500 feet below the Steve <br />23 Level involves significant technical challenges. <br />24 DRMS's position is that this is not <br />25 exceedingly difficult. To prevent damage the pump
