24 SEG NEWSLETTER No 65 • APRIL 2006... from 23Exploration Reviews (Continued)EXPLORATION REVIEWSFreegold Ventures announced additionalresults from trenching completedat their Golden Summit project nearFairbanks. The six-trench programencountered two new veins at surfacewith gold grades of 35.3 gpt gold over 5ft (grab sample of 63.7 gpt gold) and28.6 gpt gold over 5 ft (grab samples of139.0, 22.1, and 12.0 gpt gold). In addition,the strike length of the Wackwitzvein was extended to 730 ft where theshear zone hosting the vein returned 10ft grading 2.89 gpt gold. Two additionalshort trenches were excavated along theWackwitz vein and returned 59 ft grading6.4 gpt gold with four grab samplesof the vein returning grades rangingfrom 0.38 to 16.35 gpt gold.The biggest news so far in 2006came from Teck Cominco and partnerSumitomo, who announced that thePogo mine poured its first gold bar, a31.55-kg brick, on February 12. Withthis pour the mine and mill began aseveral-month shakedown of operatingsystems with the goal of reaching fullscaleproduction in the second quarterof 2006. For those of you counting, thePogo deposit was discovered in 1994and has been under continuous explorationand development since then.Total construction costs for the mine arenow estimated at $347 M. Congratulations,Teck Cominco and Sumitomo!Geoinformatics Explorationannounced that its partner, MidasResources Ltd., plans to conduct a winterdrilling program at the Uncle Samgold project in the Richardson district.The RC program will follow-up pastdrilling by Kennecott Exploration thatreturned 11 m at 2.4 gpt gold, 8 m at2.1 gpt gold, 6 m at 10.6 gpt gold, and5.5 m at 4.9 gpt gold.ALASKA RANGEUsibelli Coal Mine recently celebratedtwo milestones for their 63-year-oldoperations near Healy. The first wasthe completion of a full year of operationswithout a lost time accident during2005. This seminal event is accompaniedby a coveted Sentinels of Safetyaward to be issued by the Mine Safetyand Health Administration in conjunctionwith the National Mining Assoc.The second milestone was passing 700days without a lost time accident, arecord the company has neverexceeded. Congratulations, Usibelli!Piper Capital announced resultsfrom the Long Creek prospect on itsGolden Zone project in the centralAlaska Range. Highlights include 7 gptgold, 20.1 gpt silver, and 0.72% copperover 12.2 m and 2.35 gpt gold, 80.1 gptsilver, and 0.55% copper over 3 m inexploration trenches while diamonddrill holes returned 0.08 gpt gold, 29.2gpt silver, and 0.62% copper over 6.1 mand 1.11 gpt gold, 36.1 gpt silver, and0.40% copper over 3.0 m in hole 05 LC-1. Mineralization was extended morethan 1.5 km south from the trenchedand drilled area with rock chip sampleswhich contained up to 3.73 gpt gold,163 gpt silver, and 1.25% copper. Goldcopper-silvermineralization at LongCreek is characterized by crudely stratabounddisseminated to massive carbonatereplacement zones in limestone andcalcareous conglomerate which are cutby northeast-striking massive sulfideveins.Piper Capital also announced that ithas staked the South Estelle prospect inthe south-central Alaska Range. Reconnaissancesampling by the companyconfirmed mineralization in the previouslyreported Revelation Vein andidentified three new prospects designatedShoeshine, Train, and Saddleprospects. Highlights of grab and chipsampling from this effort include 34.4gpt gold, 8.1 gpt silver, and 0.1% copperin a vein on the Revelationprospect, 112.5 gpt gold, 245 gpt silver,and 0.13% copper in an intrusivehostedvein on the Shoeshine prospect,23.8 gpt gold, 91.4 gpt silver, and0.33% copper in a sulfide boulder trainon the Train prospect and 7 gpt goldand 1.9 gpt silver in a mineralized dikeon the Saddle prospect.Nevada Star Resource Corp.announced that JV partner AngloAmerican Exploration (USA), Inc.intends to continue exploration on theMAN project in 2006. A spring 2006drill program has been approved to testhigh-ranking targets, including electromagneticgeophysical anomalies, multielementgeochemical anomalies andpredicted down-plunge extensions ofsurface nickel-copper sulfide showings.The Alaska Industrial Developmentand Export Authority has approved a$500,000 contribution to a $1.5 M feasibilitystudy of a proposed coal-to-liquidsalternative fuels plant in the BelugaRiver coal fields 50 miles west ofAnchorage. The funding is contingenton private partners in the study completingtheir financing of the remaining$1 M needed for the study.

For the year the mine produced9,665,428 oz silver, 72,758 oz gold,21,913 t lead and 64.611 t zinc. Cashoperating costs were negative $0.66/ozwhile total operating costs were$2.18/oz. Average head grade mined forthe year was 18.17 gpt silver. Year-endproven and probable reserves stood at2,223,872 tons grading 0.12 gpt gold,14.5 gpt silver, 3.9% lead, and 10.2%zinc. Inferred resources stood at 654.214tons grading 0.14 gpt gold, 14.5 gpt silver,4.1% lead, and 11.2% zinc.Due to the number and length of newsreleases relating to mineral activity inAlaska during the quarter and thespace limitations allowable for Alaskanactivities in the SEG Newsletter, not allactivities can be included here.
