The Pebble Limited Partners has enlisted BGR Government Affairs to gain support for its controversial open-pit mine project located at the headwaters of Alaska's Bristol Bay, which is opposed by environmentalists, commercial fishermen, native Alaskans and the hospitality industry.

There’s an estimated $400B in reserves of gold, copper and molybdenum in the area, according to the Pebble Limited Partnership, which is owned by Canada’s Northern Dynasty Minerals of Vancouver.

Alaska's Republican Senators Lisa Murkowski and Dan Sullivan oppose the mine, as does sportsman Donald Trump Jr., who took his son on a fishing trip to Bristol Bay in 2014.

The Army Corps of Engineers on Nov. 25 announced it plans to block the mine because it does not comply with Clean Water Act guidelines. Pebble Limited Partnership expressed disappointment with the ruling and plans to explore its options.

BGR founding partner Haley Barbour, former Mississippi governor and chair of the Republican National Committee, and state advocacy & government marketing practice head Loren Monroe, ex-aide to New Mexico Republican senator Pete Domenici, represent the Pebble Limited Partnership.
