Seemingly South32 has a pretty good handle on the manganese issues (or non-issues) and the relatively small permitting/regulatory burdens presented in the PEA is promising. I know you have been pretty critical of this project, but seems you are coming around ever so slightly? Or do you think this project is still dead before it gets out of the ground?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6272793377504221569.post-38181624931538474592017-04-23T12:12:31.149-07:002017-04-23T12:12:31.149-07:00Hello Blue Bull - ok, I'll update the costs to...Hello Blue Bull - ok, I'll update the costs to US$1500/meter, but what advance would you expect for a 4m x 4m ramp? 1-2m a day?<br /><br />What would you estimate development rates for shaft sinking?The Angry Geologisthttps://www.blogger.com/profile/04955645007432969022noreply@blogger.comtag:blogger.com,1999:blog-6272793377504221569.post-66858012605091821772017-04-22T23:10:28.285-07:002017-04-22T23:10:28.285-07:00Decline costs could be as high as $2-2.5K/m if the...Decline costs could be as high as $2-2.5K/m if there ground is bad, but I feel $1500 would be a better. <br /><br />Totally right about the timing and early access to ore.<br /><br />Nice analysis TAG :) Bluebull2007https://www.blogger.com/profile/10387772429206099537noreply@blogger.comtag:blogger.com,1999:blog-6272793377504221569.post-62800505383126407852017-04-22T14:33:25.751-07:002017-04-22T14:33:25.751-07:00Hello Unknown,

As a mine needs to maximize the present value of the ore extracts, it needs to mine the highest grade material first, and so I would expect that they would aim for the best part of the Concha resources while they are developing into the Epitaph zone.<br /><br />if there are any mining engineers reading this, feel free to chip in and correct my costs (please)The Angry Geologisthttps://www.blogger.com/profile/04955645007432969022noreply@blogger.comtag:blogger.com,1999:blog-6272793377504221569.post-68489693927202299562017-04-22T10:00:44.600-07:002017-04-22T10:00:44.600-07:00Hi AG, thx for that post.
