David Erfle stumbled upon the mining space in 2003 as he was looking to invest into a growing sector of the market. After researching the gains made from the 2001 bottom in the tiny gold and silver complex, he became fascinated with this niche market. So much so that in 2005 he decided to sell his home and invest the entire proceeds from the sale into junior mining companies. When his account had tripled by September, 2007, he decided to quit his job as the Telecommunications Equipment Buyer at UCLA and make investing in this sector his full-time job. David founded the Junior Miner Junky subscription-based newsletter in April, 2017, which has assisted in educating thousands of investors to become successful speculators in the extremely challenging precious metals junior resource equity space.
