165:(0.68 g) of gold per ton of ore. Creeks draining the pluton were among the many productive gold placers in the heart of the Fairbanks district, since the early 1900s; and bedrock occurrences of gold or bismuth/telluride minerals were found near the pluton by early miners. Bulk-tonnage potential of the pluton was not known until exploration in the 1980s. Mine construction began in 1995, gold production commenced in 1997 with 3.8 million ounces (110 t) of gold resource estimated. In 2006 gold reserves equaled 2.7 million ounces (77 t) with additional resources of 1.6 million ounces (45 t) of gold. A heap-leaching component is being added to the original carbon-in-pulp vat leaching gold-recovery process. The mine and mill employ approximately 400 people on two shifts, 24 hours per day, 365 days per year. The Fort Knox mine produced 333 thousand troy ounces (10.4 t) of gold in 2006.
137:(real name Felice Pedroni), an Italian immigrant and Tom Gilmore discovered gold in the hills north of the Tanana and Chena Rivers in 1901. Pedro died exactly eight years after finding the richest gold placer he would ever know. By 1903 a new rush started, and prospectors staked thousands of claims. However, mining results were disappointing during the summer of 1903, with little gold recovered. Then Dennis O'Shea struck it rich on Fairbanks Creek, No. 8 Above. This was one of the richest claims in the Fairbanks Mining District and paid as high as $ 136 to the pan (gold @ $ 20/ounce). Discoveries on Cleary and Ester Creeks followed, and almost two-thirds of the gold mined in the Tanana hills before 1910 came from these three creeks. Total production of gold was more than $ 30 million. Towns grew on every creek with a combined population of 1,600 residents.

The True North mine is a recently developed, and now suspended, open pit operation that delivered its ore to the mill at Fort Knox. It is located 25 miles (40 km) northeast of
Fairbanks, on the northwest flank of Pedro Dome and approximately 11 miles (18 km) from the Ft. Knox Mine. Both
