The investment seeks results that correspond (before fees and expenses) generally to the performance of the Sprott Zacks Gold Miners Index. The index aims to track the performance of gold and silver mining companies whose stocks are traded on major U.S. exchanges. In addition to common stock or American Depository Receipts of gold mining companies, the index may include common stock or ADRs of silver mining companies. The fund will normally invest at least 90% of its net assets in securities that comprise the index. The fund is non-diversified.
