<br />Project: Cripple Creek Hydrogeochemistry Date: 4/8/2008
<br />Task: Neutralization of Pyrite Oxidation Products Page 1-3
<br />HUMIDITY CELL TESTING _
<br />The following humidit cell tests will be performed:
<br />Material Crush Test T e
<br />South Cresson 1" Large. 4 k
<br />South Cresson W Standard 1 k
<br />South Cresson #200 Sobek
<br />South Cresson + Squaw Gulch '/4" Standard 1 k
<br />South Cresson + Cresson Pie '/" Standard 1 k
<br />
<br />The tests will be conducted using the same protocol as the current HCT tests.
<br />
<br />NEUTRALIZATION TESTS
<br />Preparation of reagents
<br />ARD Water
<br />1
<br />A total of four water samples shall be prepared for testing, as follows:
<br />-
<br />9
<br />
<br />_
<br />1. Volcanic Sample: _I F I 1 1 1
<br />a. Combine 400 ml from two consecutive weekly flushes from each of the following HCTs: HC-23, HC-24, HC-26,
<br />L HC-35, for a total sample size of 3200 ml. In the event that one or more HCTs produce less than 400 ml,
<br /> make up the sample volume with liquor from the excess of the other flush volumes.
<br />b. Take a 250 ml aliquot of the sample (leaving 2,950 mL) and test for pH, conductivity, ORP, sulfate, acidity, alkalinity, TDS, Cl,
<br /> HCO3, Al, Sb, As, Ba, Be, Bi, B, Cd, C_a, Cr, Co, Cu, Fe, Pb, Li, Mg, Mn, Hg, Mo, Ni, P04, K, Se, SiO2,
<br /> Ag_, Na, Sr, Te, TI, Th, Sn, Ti, U, V, Zn, Zr.
<br />c. Store the sample unpreserved at 40C under nitrogen in an airtight opaque glass bottle until use.
<br />2. Granitic Sample:
<br />a. Combine 400 ml from two consecutive weekly flushes from each of the following HCTs: HC-28, HC-29, HC-30, HC-31,
<br /> for a total sample size of 3200 ml. In the event that one or more HCTs produce less than 400 ml, make up the sample
<br /> volume with liquor from the excess of the other flush volumes.
<br />b. Ta ke a 250 ml aliquot of the sample (leaving 2,950 mL) and test for pH, conductivity, ORP, sulfate, acidity, alkalinity, TDS, Cl,
<br /> N63-N, HCO3, Al, Sb, As, Ba, Be, Bi, B, Cd, Ca, Cr, Co, Cu, Fe, Pb, Li, Mg, Mn, Hg, Mo, Ni, P04, K, Se, Si O2,
<br /> Ag, Na, Sr, Te, TI, Th, Sn, Ti, U, V, Zn, Zr.
<br />c. Store the sample unpreserved at 41C under nitrogen in an airtight opaque glass bottle until use.
<br />3. Combined Sample:
<br />a. Combine 800 ml from
<br />two consecutive weekly flushes from each of HC-36 and HC-37, for a total sample size of 3200 ml
<br />_
<br />.
<br />In the event that one or more HCTs produce less than 800 ml, make up the volume with the excess from other flush volumes.
<br />b. Take a 250 ml aliquot of the sample (leaving 2,950 mL) and test for pH, conductivity, ORP, sulfate, acidity, alkalinity, TDS, CI,
<br /> N03-N, HCO3, Al, Sb, As, Ba, Be, Bi, B, Cd, Ca, Cr, Co, Cu, Fe, Pb, Li, Mg, Mn, Hg, Mo, Ni, P04, K, Se, SiO2,
<br /> Ag, Na, Sr, Te, TI, Th, Sn, Ti, U, V, Zn, Zr.
