Taking the slow route, he travelled via ship from New Brunswick around Cape Horn.

Although successful with several of these ventures, he remains best known for missing the Porcupine Gold Rush by only a few feet, a huge deposit being discovered directly beside one of his abandoned test digs.

His last major discovery was a major iron deposit in Labrador, although he was unable to personally develop the site due to the Wall Street Crash of 1929, which dried up development funds.

He was so well known that his death was mentioned in Time Magazine, who quoted his easygoing take on his losses in Labrador; "I was just there a darn sight too soon, but I have certainly enjoyed myself." D'Aigle was born in Chipman, New Brunswick.

In 1898 he decided to join the Klondike Gold Rush, at this point in full swing and unlikely to make any newcomers wealthy.

During one practice, when he was being subjected to a stern lecture, Costello skated over to the coach, handed him his gauntlets and stick, and said: "If you're so good, you do it".

The incident earned Costello a ticket to a farm team in Pittsburgh, and it was while there that he began to worry about becoming what he called a "hockey bum".

The Toronto team went on to defeat the Detroit Red Wings to win the Stanley Cup.

The following season Costello was frustrated by the behaviour of a coach whom he felt took the fun out of hockey.

He deposited his winnings in Seattle, and started looking for new fields, but nothing seemed to be worth investigating.
