Surface drilling continues to explore the 23-square-mile land pack- age in search of additional resources or an entirely new deposit. Ucore Rare Metals Inc. [UCU-TSXV; UURAF-OTCQX; U9U-FSE] has announced an updated mineral resource for its Dotson Ridge rare-earth-element deposit at Bokan Mountain. The updated resource estimate indicates the deposit has a total inferred and indicated resource of 6.4 million tons at 0.602% total rare earth oxides. The company is currently scoping a production plant to process heavy metals. The southwestern region of Alaska is dominated by the Pebble Project, owned by the Pebble Limited Partnership – Northern Dynasty Minerals Ltd. [NDM-TSX; NAK-NYSE], a member of the Hunter Dickinson Group. Pebble is con- sidered one of the largest undeveloped copper deposits in the world. The current resource estimate includes 6.44 billion tonnes in the measured and indicated categories containing 57 billion pounds of copper, 70 million ounces of gold and 344 million ounces of silver; and 4.46 billion tonnes in the inferred category, containing 24.5 billion pounds of cop- per, 37 million ounces of gold, 2.2 billion pounds of molybdenum and 170 million ounces of silver. In May 2017, the com- pany and the US Environmental Protection Agency reached a settlement which allows the Pebble Project to proceed into per- mitting under the Clean Water Act and National Environmental Policy Act mov- ing the project closer to submitting a final Environmental Impact Statement. NovaGold Resources Inc. [NG-TSX, NYSE MKT] and partner Barrick Gold Corp. [ABX-TSX, NYSE] have begun a US $8 million drill program to further opti- mize the Donlin Creek Project. The project operator is drilling the additional holes to better understand the exact location and grade of the gold-bearing-ore deposit. The partners plan to use any new data they collect to test the models they devel- oped through their previous research. The Donlin Creek Project currently has 9 million ounces of gold measured and indi- cated resources with a grade averaging 2.2 g/t gold. A recently updated Feasibility Study projects the project to average approximately 1,100,000 ounces of gold production per year (over an anticipated 27-year life). Redstar Gold Corp. [RGC-TSXV; RGCTF-OTCQB; RGG-FSE] continues to drill on its Unga Gold Project, where the recent 12-drill-hole exploration program, totaling 2,287.6 metres has traced the Shumagin Gold Zone approximately 1,350 metres, up from 950 metres in 2016. The work shows that the structure remains open along strike and length. The next drill program will be focused on com- pleting a mineral resource estimate. The company is planning to also drill test other high priority gold zones such as Orange Mountain, Empire Ridge, Aquila/ Amethyst, and a newly discovered foot- wall vein to the north of the Shumagin Gold Zone. At the Red Dog Mine in northwest- ern Alaska, operator Teck Alaska Inc./ Teck Resources Ltd. [TECK.B- TSX; TECK-NYSE] continued infill and defi- nition drilling ahead of mining in the Aqqaluk pit. At the end of 2016, proven and probable reserves at the mine stood at 62.4 million tons with an average grade of 14.6% zinc, 4.1% lead, and 2.15 oz/ ton silver. Teck continued an explora- tion program on its Noatak claim block, drilling 41,000 feet in the Anarraaq– Aktigiruq area about eight miles northwest of Red Dog. In the Northern Region of Alaska, Trilogy Metals Inc. [TMQ-TSX; TMQ- NYSE-MKT], formerly NovaCopper, continues to de-risk the Arctic Project, completing an updated resource estimate which at a base case 0.5% copper equiva- lent cut-off grade is estimated to contain in-pit indicated resources of 36.0 million
