with lime or limestone)to ensure that the NP to AP ratio is not acidic. Sampling frequency will be <br /> discussed with the Division as results are obtained and may be adjusted if the data are highly variable or <br /> show an increased potential for leachability of contaminants or potential for acid-formation. <br /> If the crusher fines are accumulated on-site and are potentially acid-generating,then adaptive <br /> management procedures along with the analytical results for such crusher fines, representatively <br /> composite-sampled at least quarterly or 2,000 CY whichever is more frequent,will be reviewed with the <br /> Division and implemented immediately upon such review, including use of the following management <br /> tools: <br /> 1) Compaction of placed crusher fines,and/or <br /> 2) Further amendment with lime or limestone-rich materials, and/or <br /> 3) Isolation of the fines beneath an inert cover material from the sorter, and/or <br /> 4) Placement of a revegetated cover. <br /> The Applicant will work on methods of processing the fines off-site at the mill if possible to minimize the <br /> amount contained and stored onsite. <br /> The sorting process will dramatically reduce the concentration and mass load of metals and <br /> mineralization of the material, as well as the volume of the material,to be disposed of onsite. Sample <br /> analysis of the whole waste rock can be found below. <br /> SPLP leach testing demonstrates very low potential for leachability of toxic contaminants from this waste <br /> rock. <br /> SGS Mlaarab Samplo ID: 071102224-M <br /> Tosts <br /> Tungsten 102 ugfg 3 Add DigesV1CP-MS <br /> Germaran 2 ugg 3 Add DipesOMMS <br /> Bismuth <2 ugfg 3 Add Dig WICP-MS <br /> Arse= 16 t49 3 Add DOsMP-MS <br /> Lkarrun 4.3 ugfg 3 Add DigasVICP-MS <br /> Traces Basis Dry 2 Add DgnV CP-MS <br /> Selertium 2 ug'g 2 Add D9esV1CP-MS <br /> AA Basis Dry 3 Acid DigeMCP <br /> Gold 3.46 ppn FAS-AAS <br /> SdMer 4.45 g4 Aqua Regiar'AAS <br /> Atuminrum 6.06 % 3 Acid DigesVICP <br /> Arsenic-SPLP <0.01 mg+L EPA 1312 <br /> Bann-SPLP <0.01 mgfL EPA 1312 <br /> Cadr e-SPLP <0.01 mJL EPA 1312 <br /> Chromium-SPLP <0.01 mgfL EPA 1312 <br /> Lead-SPLP <0.01 mgfL EPA 1312 <br /> Mercury-SPLP <U01 mgfL EPA 1312 <br /> SeleniuM-SPLP 4.01 mg(L EPA 1312 <br /> Won 2.75 % 3 Acid DigesViCP <br /> S4ver-SPLP <0.01 rrgL EPA 1312 <br /> Potass un 2.50 % 3 Add DWOICP <br /> Silicon 30.96 % 3 Add DigesVICP <br /> Titanium 0.15 % 3 Add DigesIMP <br />
