The investment seeks investment results that correspond (before fees and expenses) generally to the performance of its underlying index, the Sprott Zacks Junior Gold Miners Index. The fund will invest at least 90% of its net assets in securities that comprise the underlying index. The underlying index aims to track the performance of "junior" gold and junior silver mining companies whose stocks are traded on major U.S. or Canadian exchanges. Junior companies include early stage mining companies that are in the exploration stage only or that hold properties that might not ultimately produce gold or silver. It is non-diversified.
