heading &#x201c;Principal Investment Strategies&#x201d; is amended and restated to read as follows:&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0.5in; text-align: justify"&gt;The Fund&#x2019;s strategy involves: (1) constructing
a portfolio of U.S.-listed equity securities of Strategic Metals &amp;amp; Mining Companies and/or the shares of one or more Strategic Metals
&amp;amp; Mining ETFs (each Strategic Metals &amp;amp; Mining Company and Strategic Metals &amp;amp; Mining ETF is an &#x201c;Underlying Security&#x201d;
and collectively, the &#x201c;Underlying Securities&#x201d;) (the &#x201c;Equity Strategy&#x201d;); and (2) generating income through an options
portfolio (the &#x201c;Options Strategies&#x201d;), which involve using options contracts on Underlying Securities and/or Strategic Metals
&amp;amp; Mining ETFs (described below).&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Additionally, effective immediately, the third paragraph
under the heading &#x201c;Principal Investment Strategies - Equity Strategy&#x201d; is amended and restated to read as follows:&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0 9pt; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0.5in; text-align: justify"&gt;Strategic Metals &amp;amp; Mining Companies may
include companies from foreign countries, including emerging markets. In addition to or as an alternative to investing in Strategic Metals
&amp;amp; Mining Companies, the Adviser may select one or more Strategic Metals &amp;amp; Mining ETFs in which the Fund will invest. A &#x201c;Strategic
Metals &amp;amp; Mining ETF&#x201d; is a U.S.-listed ETF that seeks to track the performance of a portfolio or index primarily comprised of
Strategic Metals &amp;amp; Mining Companies. The Underlying Securities may include such companies&#x2019; U.S.-listed depositary receipts,
such as American Depositary Receipts (&#x201c;ADRs&#x201d;) and Global Depositary Receipts (&#x201c;GDRs&#x201d;). The Fund will be concentrated
in the same industry or industries as those of the Underlying Securities, which subjects the Fund to specific industry-related risks.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&#x201c;Principal Investment Risks&#x201d; are amended and supplemented with the addition of the additional risk:&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0 0.5in; text-align: justify"&gt;&lt;b&gt;Other Investment Companies Risk.&#160;&lt;/b&gt;The
Fund will incur higher and duplicative expenses when it invests in ETFs and other investment companies. By investing in another investment
company, the Fund becomes a shareholder of that investment company and bears its proportionate share of the fees and expenses of the other
investment company. There is also the risk that the Fund may suffer losses due to the investment practices of the underlying funds as
the Fund will be subject to substantially the same risks as those associated with the direct ownership of securities held by such investment
companies. ETFs may be less liquid than other investments, and thus their share values more volatile than the values of the investments
they hold. Investments in ETFs are also subject to the &#x201c;ETF Risks&#x201d; described above.&lt;/p&gt;
