Sir Martin Frobisher was an English sailor and privateer who made three voyages to the New World looking for the North-west Passage. He probably sighted Resolution Island near Labrador in north-eastern Canada, before entering Frobisher Bay and landing on present-day Baffin Island. On his second voyage, Frobisher found what he thought was gold ore and carried 200 tons of it home on three ships, where initial assaying determined it to be worth a profit of £5.20 per ton. 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.

The Northwest Passage (NWP) is the sea lane between the Atlantic and Pacific oceans through the Arctic Ocean, along the northern coast of North America via waterways through the Arctic Archipelago of Canada. The eastern route along the Arctic coasts of Norway and Siberia is accordingly called the Northeast Passage (NEP). The various islands of the archipelago are separated from one another and from Mainland Canada by a series of Arctic waterways collectively known as the Northwest Passages, Northwestern Passages or the Canadian Internal Waters.
