<br />• ! <br />1.3 Leaching and Adsorption <br />Mill feed grades were 0.0457 Au oz/ton and 0.100 Ag <br />oz/ton. Solid tails were 0.0078 Au oz/ton and 0.050 Ag <br />oz/ton. Gold and silver recoveries respectively were <br />82.9$ and 50.0$. About mid month, excessive flows in the <br />leach train simultaneous with overload conditions on the <br />tailings pump drive allowed carbon laden slurry to report <br />to the grinding area sump and hence the grinding circuit. <br />Consequently, fine loaded carbon was discharged to tails <br />for approximately ten days which resulted in low gold <br />recovery for this period. <br />1.4 Tailings Impoundment <br />Point discharge of tails in the lower impoundment ceased <br />and was replaced with spigot discharge on the main <br />embankment face. <br />Serrot Corporation was awarded the bid to complete the <br />liner installation in the upper impoundment. <br />1.5 Desorption and Refining <br />Fifteen elution cycles were completed in May. Dore <br />production for May was 2180.9 troy ounces (67.834 kg). <br />2.0 Metallurgical <br />2.1 Reagent Consumption <br />Reagent Mav YTD <br />Cyanide 0.67 1.21 <br />Lime 3.34 2.84 <br />Grinding Media <br />SAG 5.52 4.76 <br />Ball 1.32 3.35 <br />Flocculent 0.06 0.05 <br />Sulfuric Acid 3.68 3.39 <br />Carbon 0.08 0.04 <br />Sodium Hydroxide 0.98 1.03 <br />Hydrochloric Acid 0 0.01 <br />Water Treatment 0.06 0.10 <br />
