Ms. Christina Kamnikar <br /> Page 2 <br /> Venture recently purchased land near Baggs, Wyoming as a site for processing the Joker Mine <br /> ore. The proposed plan is to stockpile ore at the Joker Mine and transport the ore to Baggs, <br /> Wyoming for processing. Transportation of the ore will be performed using 20-25 ton dump <br /> trucks. Approximately 100 tons per day will be transported to the plant, which is five to six <br /> truck trips per day. Previous plans suggested the use of Liquid Organic Compound (LOC) on the <br /> stockpiled ore as a wetting agent. A decision was recently made not to apply LOC to the ore. <br /> thus no processing will occur at the Joker Mine site. <br /> The ore processing is a hypochloride leach circuit using carbon columns and possibly an <br /> electrowinning circuit to recover the precious metals. The hypochloride leach process will use <br /> the reagents listed in Table 1 below: <br /> TABLE 1 CHEMICAL REAGENTS <br /> i <br /> Hydrochloric Acid (HCI), 37% solution j <br /> Sodium Hypochlorite (NaOCI), a 12.5% solution <br /> Sodium Chloride (NaCI) <br /> Anionic Flocculant <br /> DADMAC Flocculant <br /> Sodium Hydroxide (NaOH) <br /> Carbon <br /> Antiscalent (associated with the Boiler) <br /> Following processing of the ore, the tailing material will be trucked back to the Joker Mine and <br /> placed in the pits as backfill. Knight Piesold recently sent a letter dated December 22, 1997, to <br /> the Department of Geology (DMG) providing Synthetic Precipitation Leaching Procedure <br /> (SPLP) data on the leachate from a sample of tailing material. The DMG responded with <br /> concerns in a letter dated January 9, 1998. Knight Piesold responded to those concerns in a letter <br /> dated January 26, 1998. Because of the concerns regarding the levels of chloride in the leachate, <br /> a revised rinsing process has been designed for the pilot process. <br /> Another sample of tailing which more closely represents the material being mined was rinsed <br /> more thoroughly and analyzed using the SPLP. The SPLP testing method (EPA Method 1312) <br /> may be used to characterize waste material for the potential to release metals and other <br /> constituent into the environment in unacceptable amounts due to exposure to normal meteoric <br /> precipitation. In the procedure a minimum of 100 grams of solid waste is combined with 20 <br />
