3.2 Sampling Overview <br />5 , <br />The trips to the Battle Mountain Gold Mine will be on a "surprise" basis (the company will <br />receive notification of the visit a number of hours in advance). The first sampling trip will <br />include a site tour to familiarize the third-party sampler with the facility and processes used <br />at the facility that may affect sample concentrations and/or collection. The site tour may <br />include a brief tour of the open pits, the waste rock and tailings disposal areas, the <br />beneficiation and processing units, and any other relevant units or areas at the facility. '['Ite <br />third-party sampler will provide transportation from the point of origination (in this case, <br />Boulder, Colorado) to the Battle Mountain-San Luis facility and the analytical laboratory. <br />Prior to arriving at the facility on each sampling date, the third-party sampler will pick up <br />sampling bottles at a laboratory approved and chosen by the Division. Any sample <br />preservation reagents will be added to the bottles by the laboratory before pick-up. An <br />environmental engineer from Battle Mountain Gold, or an affiliated consultant, will actually <br />conduct the sampling, perform tests for field parameters, and process the samples in the <br />5eld. Samples will be taken from three ponds (the collection pond and two tailings ponds); <br />three groundwater monitoring wells, and possibly Rito Seco Creek. There could be up to <br />eight groundwater monitoring well samples taken from different screened intervals. All <br />samples will be filtered through a 0.45 micron filter upon collection. The third-party sampler <br />will be provided with filtered sphts of all samples collected. Filled third-party sampling <br />bottles will be returned to the approved laboratory by the thud-party sampler following strict <br />protocol, QA/QC procedures, and chain of custody requirements. <br />3.3 Sampling and Analytical Protocol <br />The sampling and analytical protocol will be defined by Harry Posey of the Mined Land <br />Reclamation Division. A QA/QC protocol document is currently being prepared for the <br />collection of surface and groundwater quality data. This document will prescribe methods <br />for the collection of groundwater, surface water, lysimeter and process samples; for the <br />analysis of cyanide (total, WAD and free ryanide -- possibly maximum free cyanide by <br />difference); for 5eld quality control, and for other crucial aspects of sample collection, <br />handling and analysis. For example, the groundwater sample collection protocol will include <br />methods for: cleaning of sampling equipment; sample containers; sample collection and <br />handling; groundwater sampling; locking wells; water levels and measurements; well <br />evacuation; groundwater sampling method; field parameter measuremenu, and sample <br />5ltration. An opportunity will be provided for the thud-party sampler to comment on the <br />sampling and analytical protocol document (see below). <br />RCG/Hagler, Bailty, Inc <br /> <br /> <br />1 <br /> <br /> <br />LI <br />1 <br /> <br /> <br /> <br /> <br />1 <br /> <br /> <br /> <br /> <br />1 <br />
