Sampling,,viIl be performed at each well on a quarterly basis,and logged in an auditable Company record Ideally. <br /> there should be no water detected,indicating that systems are working corrcclly. If water is encountered it could be <br /> related to a potential problem or temporary saturation from a recent storm event. In either event,the DRMS requires <br /> a report within five working days if water is encountered This report must immediately provide die pH value and <br /> die purged volume. Laboratory analysis should follow as soon as the results are attained from the tab. Metals to be <br /> tested shall include: Al,As,Ba,Cd,Cr,Cu,Pb,Mn,Hg,Sc,Ag,and Zn. if the testing indicates a dry result,this <br /> data should be collected for reporting to the DRMS in the annual reclamation report <br /> The following monitoring/sampling parameters slkill be followed for each 11-cil: <br /> 1. Unlock and open security cap. <br /> 2. Insert a clean bailer-style sampler(nominally 0.5"-1.5"OD x 12'L)into lire casing and lower via a clean, <br /> nylon cord. <br /> 3. Let the sampler reside at die bottom of the rasing(25')for at least 2 minutes. <br /> d. Carefully pull die sampler back to the surface. <br /> 5. Label a new clean bottle and complete the report"it],file following data: <br /> a. Date/time of sample <br /> b. Location,Up-or Down-Gradienl <br /> c. Approx.depth of liquid level in bailer,in inches from bottom of borehole. <br /> d. Purged volume <br /> c. pH value to i/10°i of a standard unit using a properly calibrated handheld pH meter <br /> f. If none collected,record on report"Dry,- <br /> 9. Sampler's signature <br /> 6. Pour any contents into the labeled, clean,plastic sampling bottle. <br /> 7. Procodure##2-#i6 shall be repeated three times as a purging procedure if n-aler is encountered. <br /> a. The fourth boule collected shall be submitted for sampling or,the last bottle taken if the well goes <br /> dry during the purging sequence. <br /> 8. The sample report skill be recorded Willi the Venture Resources'office. <br /> a. If water is encountered,the preliminary field report with pH value and purged volume shall be <br /> submitted to[lie DBMS within five working days <br /> 9. Am collected water will be forwarded to an independent anah7ical laboratory that can perform file <br /> following test: Al,As,Ba,Cd,Cr,Cu,Pb,MA fig,Sc,Ag,and Zn metals-total concentration. <br /> 10. Rctumcd lab results will be attached to the appropriate field report and maintained at the Vcnturc <br /> Resources'office. This data will be preserved for the entire life of the operations. <br /> a. These test results shall also be immediately fonvardcd to DBMS upon receipt_ <br /> 11. In the event that data is received indicating a problem, ie reported levels are higher than the baseline values <br /> established in Exhibit C,operations shall be ordered CEASED rnitil the problem can be identified and <br /> corrected. <br /> It shall be noted,the Colorado School of Mincs owns over a dozen properties down-gradient of this proposed <br /> operation.One of which,the Edgar Union Lode,contains three large dumps that arc 350'downgrade from the <br /> proposed Tailings Impoundment. Inorder to not be adversely impacted by the acid runoff from the CO School of <br /> Mines' property,die aforementioned monitoring well will be the best monitoring point. <br /> Biodegradable geotextile slialI be pinned to the exposed surface face to minimize wind and/or stor imter erosion on <br /> a as-needed basis. This will be done until permanent stabilization through revegetation and/or rip rap can be <br /> installed. Pennanent control measures trill be installed in 10 feet phased increments(elevation height of one quarter <br /> of a terrace or bench)which is estimated to occur every several months. This consists of covering the impoundment <br /> area with a 6"blend of Class-A municipal bio-solids and topsoil. A biodegradable netting will then be applied to <br /> prevent water and wind erosion. This application will augment the deposited solids for the establishment of soil <br /> capable of supporting re-vegetation. <br /> A grass seed mix has been developed specifically for this site through consultation with die Natural Resource <br /> Conservation Smicc(see MRCS seed mix specification attached as an appendix to Exhibit D).This mill be sowed <br /> logether with fertilization and irrigation unti I permanent vegetation is re-established. <br /> Page 30 of 37 <br />
