In a long overdue step to bring Alaska into the 21st century, State and Federal agencies met in late June to discuss collaborative funding strategies for Alaska’s Statewide Digital Mapping Initiative (SDMI), an initiative designed to create Alaska’s first high-quality digital topographic map. The roundtable was convened by Alaska Lt. Governor Mead Treadwell and U.S. Department of Interior’s Assistant Secretary for Water and Science. Alaska remains the only State in the U.S. that has not been digitally mapped and its current maps do not meet National Map Accuracy Standards. Alaska has contributed funding in the past that resulted in digital mapping that covered 10% of Alaska. In a statement that will live beyond this administration, Lt. Governor Treadwell said “Mars and the moon have been better mapped than Alaska.” As someone who has flown and walked over large areas of the state, I can attest to the accuracy of Lt. Governor Treadwell’s statement. I have found mountain tops where the maps say none exist and I have gone looking for mountain tops shown on maps only to find that these peaks in fact do not exist in the real world. While Alaska’s Statewide Digital Mapping Initiative will greatly assist the mineral industry, it also will have immediate applications across a wide spectrum of disciplines. |

Tintina Resources Inc. announced the commencement of the first exploration drill campaign at its Baird project in the Western Brooks Range. The company plans to drill several kilometric-scale copper-zinc surface anomalies will be tested with 2,500 meters of drilling. The program will focus on previously identified mineral targets at the Omar, Deadfall, and Frost targets. The Omar target exhibits mineralization over an area measuring 4 kilometer by 2 kilometer with coincident copper and zinc soil and rock chip anomalies. Historic drilling results showed significant bedrock mineralization including 22.8 meters grading 3.99% copper, 6.1 meters grading 9.37% copper and 7.32 meters grading 2.95% copper. The Deadfall target consists of a 4 kilometer long zinc and copper anomaly. Although no drilling has been completed on this target, channel sampling has identified significant bedrock mineralization including 36 meters grading 6% zinc and 21.7 grams of silver per tonne including 12 meters grading 10.1% zinc and 42.4 grams of silver per tonne. ,000 tonnes of zinc concentrate and 145,000 tonnes of lead concentrate. During the third quarter the mine paid out $61 million in royalties to its partner, NANA Regional Corp.Graphite One Resources Inc. announced rock sampling results and commencement of drilling at its Graphite Creek graphite prospect on the Seward Peninsula. Twelve rock grab samples were collected along the electromagnetic conductor and ten of the samples contained graphite with grades ranging from 0.77% to 41.4% graphitic carbon. Follow up work included collection of 307 rock grab samples, geologic mapping along the known electromagnetic conductor and completion of two drill holes which tested surface graphite showings near Graphite Creek. The company also collected three surface bulk samples which total approximately 10.5 metric tonnes. Theses samples will be used for mineralogy and metallurgical testing. Millrock Resources Inc. announced an update on its plans for its Humble project in southwestern Alaska and its Council project on the Seward peninsula. At Humble, Millrock and partner Kinross Gold Corporation are contemplating a follow-up drilling program for later in 2012. At Council, Millrock and partner Kinross Gold Corporation plan to drill six shallow holes to test strong surface gold geochemical anomalies and gold-bearing veins discovered by prospecting crews at the Elkhorn prospect. The project is budgeted at $1 million.NovaGold Resources Inc. and partner Barrick Gold Corporation approved their recently completed update feasibility study and approved the long-awaited permitting process for their Donlin Creek gold deposit. When in production, the deposit is expected to produce approximately 1,500,000 ounces of gold per year in the first five full years of production and average more than 1,000,000 ounces of gold per year over a 27 year mine life. Current measured and indicated resources stand at 39 million ounces of gold contained in 541 million tonnes grading 2.2 grams of gold per tonne. Permitting, through the Federal National Environmental Policy Act (NEPA) will include completion of an Environmental Impact Statement. Nyac Gold LLC reported the completion of a 920-meter diamond drill hole at its Saddle Mountain prospect at its Nyac gold property under lease from Calista Corp. The hole was drilled near the center of a 7.5-acre hydrothermal breccia pipe that is coincident with a roughly circular 2,450-meter diameter aeromagnetic anomaly thought to represent an underlying Cretaceous pluton. Surface quartz vein samples in the breccia pipe have yielded up to 59.2 grams of gold per tonne with anomalous silver and mercury values. The hole cut pervasively potassically altered andesite with biotite flooding plus disseminated and vein magnetite. Anhydrite veining and flooding is prevalent to a depth of 750 meters. Hydrothermal alteration and fluidized hydrothermal brecciation often obliterate original textures. Significant intercepts include 16 feet grading 4.9 meters of quartz-carbonate vein breccia at 580 meters and 28 meters of intensely quartz-sericite-pyrite-altered porphyritic intrusive in two intervals below 812 meters. The altered intrusive is similar to a mineralized cupola occurring elsewhere on the property that may have generated the placer gold deposit in the creek draining the cupola. The hole was terminated in silicified quartz-sericite-pyrite-altered andesite that contains up to 2 volume percent fine quartz-chlorite-anhydrite stockwork. The company intends to complete at least 2,440 meters of drilling in deep holes in the breccia pipe this season. Liberty Star Uranium & Metals Corp. announced receipt of updated geophysical data from its ZTEM electromagnetic survey covering the south block of its Big Chuck project. Reprocessing of these data is in progress. TNR Gold Corp. announced that drilling and other exploration work on schedule for start-up in mid-July at its Shotgun gold project. Objectives of the Shotgun Gold Ridge prospect drill program include approximately 1500 meters of infill drilling to support an industry-compliant resource estimate, testing of new geophysical targets identified in 2011, further testing at depth on feeder zones discovered in 2006 and completion of additional geophysical surveys on other parts of the project. |

Freegold Ventures Limited announced additional drilling results from its Golden Summit project near Fairbanks. At the Dolphin zone, significant results 136.7 meters grading 1.57 grams of gold per tonne in hole GSDL1213 within a broader zone of mineralization grading 0.82 grams of gold per tonne over 542.8 meters (collar to termination depth). Mineralization is hosted in pervasively sericite altered granodiorite cut by later sheeted and stockwork quartz veins. Elevated god values are associated with disseminated and quartz vein-hosted arsenopyrite and pyrite with lesser silver and lead sulfosalts. Additional drilling is on-gong in the Dolphin zone and is planned for other areas of the project in 2012.Teryl Resources Corp.announced that exploration work was planned for its Westridge gold project in the Fairbanks District. The proposed initial work programs will include locating and surveying historic drill holes on the ground within the claim block, a reconnaissance drilling program utilizing a small diameter drill rig, upgrading of access and water source areas, general reconnaissance of the placer potential on Moose Creek and securing a larger-diameter diamond drill or a reverse circulation drill for follow-up drilling. The company plans to complete 760 meters of drilling this season. International Tower Hill Mines Ltd.announced an update regarding the optimization review of its Livengood project. The company has determined that the most efficient and cost-effective path to permitting is to incorporate results from current engineering and metallurgical test work directly into a definitive feasibility study, which the company expects to complete in the first half of 2013. Earlier this year the company sent SGS Canada Inc. 10,800 kilograms of material from approximately 3,000 samples selected from throughout the deposit for the final stage of metallurgical optimization testing and analysis. Results are pending. Additional optimization work is looking at crushing and grinding and over-all mill scale options. Mill and facilities condemnation studies also are ongoing. Budget reductions have forced the company to postpone much of its district-wide exploration drilling program and reduce a portion of its condemnation drill program. The company will focus on completing all the necessary field work and drilling to support the completion of a feasibility study and the environmental work needed to keep its permitting schedule on track. The company also reported on the identification of 5 five key exploration areas with the potential to provide substantial resource growth over time and which would be the focus of the company’s future mine-area drill programs. These areas include the Scraper Ridge, Money Knob Pit, SW, Gertrude Basin and Moose Gulch/Lucky Creek areas. The presence of a combination of dikes, volcanic host rocks and a large gold in soil anomaly indicates potential for the discovery of mineral resources in the newly identified Scraper Ridge target. Mineralization has been confirmed in scout hole MK-10-97 which intersected 1.52 meters of 4.82 grams of gold per tonne in the most favorable host rocks. Gold in soil and other diagnostic geochemical pathfinders have outlined a large, coherent target area. To date, almost all of the drill holes in the Money Knob deposit have bottomed in gold mineralization and six deep holes extending below the proposed 300-meter pit bottom penetrated intervals with similar gold grades to the main deposit. Additional mineral resources may be defined below the current pit design by sequential drilling conducted as part of an ongoing mining operation. Previously identified mineralized intercepts in the northern portion of the SW Zone include 15.24 meters at 3.69 grams of gold per tonne and 22.86 meters grading 0.86 grams of gold per tonne. These intercepts are relatively shallow and indicate an opportunity for the delineation of resources that might extend early mining in the proposed pit towards the west. Deep, well-mineralized intersections in the southern part of the SW zone offer the possibility of extending the present mineral resource to the southwest later in the life of the proposed project. Geotechnical drilling in the Gertrude Basin area has intersected dike-related mineralization in favorable host rocks within a large gold in soil anomaly. Significant results include 1.68 meters grading 5.72 grams of gold per tonne, 9.77 meters at 0.83 grams of gold per tonne and 9.85 meters assaying 0.65 grams of gold per tonne. In the Moose Gulch/Lucky Creek area, northwest trending faults, dikes and anomalous gold in soils coincide. Exploration and geotechnical drilling in the area has encountered gold mineralization, mostly in and immediately adjacent to dikes, including 3.56 meters at 2.0 grams of gold per tonne and 6.07 meters grading 0.67 grams of gold per tonne. Alix Resources Corp. announced that it has completed phase one sampling at its Money Rock and West Pogo gold projects in the Goodpaster Mining District. Over 300 samples have been collected to date, including 210 soil, 34 stream sediment, and 82 rock grab samples. A 1,800 meter drilling program has now commenced. Previous work at West Pogo identified two zones of gold mineralization from rock-chip grab samples with up to 118.5 grams of gold per tonne. Drilling has begun within the larger of these two zones and is designed to test for potential mineralization along roughly northwest-trending structures identified through re-interpretation of geophysical data. Sono Resources, Inc. announced that it had changed its name to Alaska Gold Corp. and commenced its 2012 exploration program on its Bear project in the Circle District. The company collected 219 mobile metal ion geochemical samples and followed up with a three dimensional induced polarization/resistivity survey. The company hopes to identify 6 to 10 drill targets where it can subsequently complete 4,000 to 6,000 feet of diamond core drilling later in 2012. In what we all hope is a shape of things to come, The Dept. of Transportation and Public Facilities announced that step one of the Roads to Resources program has begun with clearing and surveying of the proposed road from Manley Hot Springs to Tanana Village. Both the State of Alaska and the Alaska Industrial Development and Export Authority are funding this initial $10 million effort. The goal will be creating of a summary document that will be subject to public comments. The land along this segment of the corridor is owned partly by the State of Alaska and party by the Tozitna Native Corporation. |

The average mine employee has been employed there for 9 years. A total of 46 employees have been at the mine for more than 10 years with 11 of those having been employed for over 30 years at Usibelli Mine. Approximately 27% of the workforce, or 39 employees, are second, third or fourth generation employees.Corvus Gold Inc. Corvus Gold Inc. announced that joint venture partner Ocean Park Ventures Corp. has not finalized their exploration program for the summer but have indicated Corvus Gold that it will be limited in scope as necessary to fulfill their remaining 2012 work commitment.Pure Nickel Inc. announced that its $4.9 million 2012 exploration program at the MAN project, funded by partner Itochu Corporation, began in late May, with mapping, soil geochemistry and induced polarization geophysical surveys. Drilling began in late June with a total of 2,600 meters expected to be completed by the end of the program. GTSO Resources announced that, in addition to its gold properties already under evaluation, it has begun evaluation of tungsten prospects in Alaska. The initiative grew out of the results from the company’s black sands core samples collected in June. Millrock Resources and partner Teck American Inc. announced that drilling has commenced at the Estelle project. The $1.8 million drilling program will include seven holes totaling up to 1,500 meters of drilling. Five of the planned holes will be drilled at the previously drilled Oxide Ridge prospect. Previous drilling intersected variably altered magmatic intrusive rock with quartz veins and stockworks containing gold mineralization which returned a 0.43 grams of gold per tonne over 365.3 meters. Corvus Gold Inc. announced that joint venture partner Westmountain Index Advisors Inc. will conduct additional exploration at the Terra property this summer. Work will include core drilling and installation and operation of a small mill that will utilize stockpiled material left on site. The company also plans to begin construction of the road from the project camp to the main mining area at the Ben Vein. Diamond drilling will focus on the continued extension of the Ben Vein to the north as well as infilling the additional 200 meters of vein extension delineated in 2011. |

NovaGold Resources Inc. and NANA Regional Corporation, Inc. announced initial industry compliant resources estimates for the Bornite copper-cobalt prospect at its Upper Kobuk project in the Ambler District. At a 0.5% copper cutoff grade, the Ruby Creek Zone of the Bornite deposit contains Indicated Resources of 6.8 million tonnes at 1.19% copper or 178.7 million pounds of contained copper. In addition, at a 0.5% copper cutoff grade, the Ruby Creek Zone contains Inferred Resources of 47 million tonnes of 0.84% copper or 883.2 million pounds of contained copper. The Ruby Creek Zone resource does not include any of South Reef target mineralization located roughly 600 meters east of the Ruby Creek Zone. Exploration drilling at South Reef in 2011 encountered exceptional grade-thickness intervals, including 178 meters grading 4.01% copper, including a 34.7 meter section grading 12.03% copper. Mineralization in the Ruby Creek Zone occurs as two discrete strata bound lenses: a Lower Reef which outcrops and dips approximately 30 degrees to the northeast; and an Upper Reef lying roughly 150 meters above the Lower Reef stratigraphy and which includes a small high-grade zone named the No.1 Orebody by Kennecott. Mineralization is hosted by a Devonian age carbonate sequence containing broad zones of silica-dolomite alteration and associated sulfide mineralization including bornite, chalcopyrite, chalcocite occurring as disseminations and vein stockworks as well as crackle and mosaic breccia fill and locally massive to semi-massive replacement bodies. Four rigs are currently drilling at the project with the goal of completing 15-18,000 meters of diamond drilling in two principal areas: the South Reef and Ruby Creek Zones at Bornite and the Sunshine deposit, a satellite polymetallic volcanogenic massive sulfide deposit located 12 kilometers west of the Arctic volcanogenic massive sulfide deposit where previous drilling identified significant intersections of massive sulfide mineralization in the same stratigraphic horizon as the Arctic deposit. The $16.5 million 2012 exploration program also consists of extensive surface exploration of the roughly 18 kilometer long belt of prospective carbonate stratigraphy adjacent to the Bornite deposit. Two known mineralized occurrences (Aurora Mtn. and Pardner Hill) along with broad areas of hydrothermal dolomite and anomalous soil geochemistry occur along the belt. Surface exploration will utilize 60+ line kilometers of wide-spaced dipole/dipole induced polarization and radial line down-hole IP and 25 line kilometers of soil sampling. Andover Mining Corp. announced initial drilling results from its 2012 drill program at the SUN copper-silver-lead-zinc-gold volcanogenic massive sulfide project in the Ambler District. Drill hole SUN 12-29 was the first drill hole of the 2012 drill program and returned 8.6 meters grading 1.49% copper, 1.6% lead, 9.03% zinc, 66.2 grams of silver per tonne and 0.190 grams of gold per tonne from 71.9 to 80.5 meters depth, 6.2 meters grading 2.73% copper, 1.27% lead, 6.54% zinc, 116.4 grams of silver per tonne and 0.396 grams of gold per tonne from 100.5 to 106.7 meters depth and 2.3 meters grading 1.68% copper, 0.26% lead, 1.04% zinc, 48.9 grams of silver per tonne and 0.142 grams of gold per tonne from 130 to 132.3 meters depth. Drilling continues on both the SUN and S.W. SUN deposits. Goldrich Mining Company and partner NyacAU, LLC receipt of its placer mining permit at its Chandalar project in the Brooks Range. Ground preparation has begun and the companies anticipate the gold recovery plant will be set up by mid-August. Commercial production is anticipated to begin by June 2013, although limited production could begin as early as this summer. An eventual production rate of approximately 10,000 ounces of fine gold per season for 25 years is anticipated with the option to increase this production rate by establishing a second gold recovery plant. |

Grande Portage Resources Ltd. announced that it had begun drilling at its Herbert Glacier gold project in the Juneau Gold Belt. The 2012 seventy-hole drill program will be divided into two primary objectives deeper drilling on 25 meter spacings in order to convert inferred ounces into the measured and indicated category and an additional 3000 meters of relatively shallow drilling on 4 of the 5 principle vein structures. Each structure has a surface expression of approximately 1,000 meters. Arrowstar Resources Ltd. announced initial results from its first exploration program on its Snettisham iron ore prospect about 30 miles southeast of Juneau. Ten grab samples were tested for magnetic separation using a Davis Tube Test methodology with recovering ranging up to 86.7% of the magnetite in pyroxenite host with an over-all iron content of 57. A bulk sampling program is planned as the next step to concentrate the sampling in these two areas to determine the extent of each occurrence. Proposals are being reviewed for a ground based magnetic program that will be conducted prior to initial drill testing. Heatherdale Resources Ltd. announced details of its planned 2012 exploration program at its Niblack volcanogenic massive sulfide deposit. The 2012 program will be staged from surface sites to test areas that could not be efficiently tested from existing underground workings. The 15,000 foot program mainly targets the open extensions of the Lookout and Trio deposits, as well as focusing on several other key targets along the property's six miles of prospective felsic stratigraphy, which is known to host at least six massive sulfide zones. Current resources comprise indicated resources of 5.6 million tonnes grading 0.95% copper, 1.75 grams of gold per tonne, 1.73% zinc, 29.52 grams of silver per tonne and an additional inferred resource of 3.4 million tonnes grading 0.81% copper, 1.32 grams of gold per tonne, 1.29% zinc, 20.10 grams of silver per tonne. |
