Much of the world’s gold is mined from networks of branching mineral layers — or veins — made mostly of quartz, called orogenic gold deposits. These deposits are constructed piecemeal by ...

Some people think orogenic gold deposits can form in thousands of years, some others think it's millions. The amount of variables that go into geological systems makes it difficult to say for sure." ...

So, gold in quartz veins will solidify into clusters that grow bigger every time an earthquake occurs. To date, the largest orogenic gold nuggets weigh approximately 130 pounds.

Gold naturally forms in quartz — the second-most abundant mineral in Earth's crust after feldspar. But unlike other types of gold deposits, those found in quartz often cluster into giant nuggets.

With historical gold production of 785,000 ounces, worth about $1 billion at today’s prices, Sheep Creek is quite relevant as the third largest past-producing orogenic gold district in the province.
