The <br />purpose of our sampling was: <br />1. to verify that rock in Arequa and Squaw Gulches have less than 0.8% sulfur, <br />and <br />2. to determine the acid generating potential of the Iron Clad waste rock pit. <br />Following is a synthesis of the results. <br />AREQUA GULCH <br />No. S <br />1 0.2 <br />2 0.4 <br />3 0.1 <br />4 bdl' <br />5 0.4 <br />6 bdl <br />SQUAW GULCH <br />1 0.2 <br />2 bdl <br />3 0.3 <br />4 0.1 <br />5 0.1 <br />IRON CLAD PTT <br />No. AGPZ ANP3 AGP/ANP Ratio4 <br />1 17.6 24 0.73 <br />2 64.3 6 10.7 <br />3 49.4 11 4.5 <br />4 18.4 12 1.5 <br />5 21.7 8 2.7 <br />
