The Rock Creek Project is located on the Seward Peninsula along the west coast of Alaska. There are two project components: the Rock Creek Mine/Mill Complex located about 6 miles north of Nome in the Snake River watershed, and the Big Hurrah Mine located about 42 miles east of Nome in the Solomon River watershed. Both are proposed to be developed as open pit gold mines by the project applicant, Alaska Gold Company (AGC), a wholly owned subsidiary of NovaGold Resources, Inc.

The known gold resource at the Rock Creek Mine/Mill Complex lies within land owned approximately 66% by AGC, with the remainder within Bering Straits Native Corporation (BSNC) lands. At Big Hurrah site, the known gold resource lies within land owned 100% by AGC, and the surrounding lands are owned by Solomon Native Corporation.

The Rock Creek Mine/Mill Complex as planned includes an open pit mine, two non-acid-generating development rock stockpiles, a gold recovery plant, and a paste tailings storage facility. Standard drilling and blasting techniques would be used to break the ore. Ore milling rates would be about 2.75 million tons/year, while development rock stripping volumes would be in the range of 4.4 to 5.5 million tons/year. Milling would include crushing, screening, gravity separation, flotation, and a cyanide leaching process. The expected mine life is 4.5 years, with potential for additional discovery and expansion. The project would employ up to 135 employees.

The Big Hurrah component consists of a smaller open pit gold mine, a non-acid-generating development rock stockpile, a temporary stockpile for acid-generating development rock that would later be backfilled into the pit, and an ore stockpile. Ore would be trucked to the Rock Creek Mine/Mill Complex to be milled. Ore would be mined at a 1,500 tons/day rate on a seasonal basis for a total of approximately 270,000 tons/year for 4 years.
