On his second voyage, Frobisher found what he thought was gold ore and carried of it home on three ships, where initial assaying determined it to be worth a profit of £5.20 per ton (equivalent to £ per ton in ). Encouraged, Frobisher returned to Canada with an even larger fleet and dug several mines around Frobisher Bay. He carried 1,350 tons of the ore back to England, where, after years of smelting, it was realized that the ore was a worthless rock containing the mineral hornblende. As an English privateer, he plundered riches from French ships. He was later knighted for his service in repelling the Spanish Armada in 1588. Provided by Wikipedia
