Since acquiring Pebble in 2001, Northern Dynasty has expanded known mineral resources from one to nearly 11 billion tonnes, while discovering significant new areas of high-grade mineralization. With ~1,000,000 feet of drilling in ~1,200 holes, a significant proportion of known mineralization at Pebble is in measured or indicated categories.
In total, the current Pebble resource estimate includes 5.94 billion tonnes in the measured and indicated category containing 55 billion lb copper, 67 million oz gold and 3.3 billion lb molybdenum; and 4.84 billion tonnes in the inferred category, containing 26 billion lb copper, 40 million oz gold and 2.3 billion lb molybdenum. Quantities of silver, palladium and rhenium also occur in the deposit. The Pebble deposit has the volumes, grades, and metallurgy to support a modern, long-life mine.
