Per United States Geological Survey Bulletin 750-Observations on the Rich Silver Ores of Aspen <br /> Colorado-Mine water analysis in Durant tunnel(Compromise mine)and Smuggler mine is neutral <br /> or slightly alkaline and not acidic-attached are the text and diagrams from Bulletin 750 for <br /> reference: <br /> DESCENDING] MINE WATERS. <br /> Mine waters, all clear and cool and descending, were tested at <br /> several places in the workings, and two samples were analyzed. <br /> (See fig. 22.) <br /> A/ka/:ss a•X Earths 44.4 X Meta/s A 2 X <br /> Durant •�. •••• •< rc•ri'1) w ,Lv >1 try}AJ'�i:/.- ,,.. <br /> tunnel • d7t•• Lw�n v 7�� TSS�O �r� aq>.r•);,-2.XB7LwL' 4•% <br /> • • •cq 7 >R (+•w> yv>w cy LAa��1 ter) <br /> Strong acids 35.9 yG Welk ai ds/�,* <br /> Alkalies a <br /> 6.9X Earths 42.9 K Metah 0.2X <br /> Ira/or./ -%sax. s.B';1 :%t:- ;_4.9_?32's 0�: ._ �,,._::r: n4x <br /> StlA?! zrda ' <br /> • <br /> • •••• �. ._ <br /> A/kakas to esnced Earths ba/anced Ea /anted <br /> by strong aces by strong acids y ar/o•J <br /> ffeooaa 22,—Composition diagrams of cool demanding mine waters of Amon. Cole <br /> Cool, clear water dripping from the roof of stops No. 4 in the <br /> Durant tunnel workings under Aspen Mountain, at a vertical depth <br /> of about 900 feet, was not acid toward methyl orange but on the <br /> contrary gave a faint pink coloration with phenolphthalein, indicat- <br /> ing faint alkalinity due to the presence of normal carbonates in solu- <br /> tion. There were no stopes for considerable distances above this <br /> point. The analysis of this water is given on page 58. Water that <br /> was being pumped from the Smuggler mine gave similar reactions. <br /> Water dripping through the "contact" on the first level of the <br /> Aspen mine, Aspen Mountain,at a depth of about 150 feet vertically <br /> below the surface, was neutral. There were no stopes above the <br /> point where this water was tested. Water dripping from the roof <br /> of the Hooper scope, on the third level of the Aspen mine, was also <br /> neutral. <br /> Durant mama, <br /> IAnalyst,Cbass Palmer.U.S.Geol.Bgrvey.l pp <br /> .
