The Pacific Coastal Temperate Rainforest, stretching from Northern California into Alaska, is known best for things that grow above the ground — like the world’s tallest trees, and in its waters, like the legendary salmon runs. But we know far less about treasures lurking underground, like the vein of rare earth elements tucked away deep within Alaska’s Tongass National Forest – America’s largest national forest.
This cache of highly valued minerals is buried under Bokan Mountain, a small peak at the remote southern tip of Prince of Wales Island, the southernmost island in the Southeast Alaskan archipelago and the fourth largest island in the United States.
Ucore Rare Metals Inc., a Nova Scotia-based company, owns the rights to build a mine at the site. In a recent letter to Uncore shareholders, the company’s president and CEO Jim McKenzie, says it has located 5.3 million tons of “the most valuable, sought after, strategically important, and hard-to-obtain” varieties of rare earths in Bokan. That makes it one of the largest lodes of rare earth elements ever found in the United States, according to the US Geological Survey.
Geos Institute depends on the generous support of caring people who believe we can and must do a better job addressing climate change for our children and those who will follow.
