(a)

Performance returns for periods of less than one year are not annualized. The CBOE S&P 500 Buy/Write Index is an unmanaged benchmark index designed to reflect the return on a portfolio that consists of a long position in the stocks in the S&P 500 Index and a short position in a S&P 500 (SPX) call option. The Philadelphia Gold & Silver Index is an unmanaged indicator of stock market performance of large North American gold and silver companies. The Dow Jones U.S. Basic Materials Index measures the performance of the basic materials sector of the U.S. equity market. The S&P Global Agribusiness Equity Index is designed to provide exposure to twenty-four of the largest publicly traded agribusiness companies, comprised of a mix of Producers, Distributors & Processors, and Equipment & Materials Suppliers companies. Dividends are considered reinvested. You cannot invest directly in an index.

(b)

Total returns and average annual returns reflect changes in the NAV per share and reinvestment of distributions at NAV on the ex-dividend date and are net of expenses. Since inception return is based on an initial NAV of $19.06.

(c)

Total returns and average returns reflect changes in closing market values on the NYSE and reinvestment of distributions. Since inception return is based on an initial offering price of $20.00.

(d)

From January 31, 2011, the date closest to the Fund’s inception for which data are available.

Investors should carefully consider the investment objectives, risks, charges, are expenses of the Fund before investing.

Returns represent past performance and do not guarantee future results. Investment returns and the principal value of an investment will fluctuate. The Fund’s use of leverage may magnify the volatility of net asset value changes versus funds that do not employ leverage. When shares are sold, they may be worth more or less than their original cost. Current performance may be lower or higher than the performance data presented. Visit www.gabelli.com for performance information as of the most recent month end.

GAMCO Natural Resources, Gold & Income Trust

Notes to Financial Statements (Unaudited)

1. Organization. The GAMCO Natural Resources, Gold & Income Trust (the Fund) is a non-diversified closed-end management investment company organized as a Delaware statutory trust on June 26, 2008 and registered under the Investment Company Act of 1940, as amended (the 1940 Act). Investment operations commenced on January 27, 2011.

The Fund’s primary investment objective is to provide a high level of current income from interest, dividends, and option premiums. The Fund’s secondary investment objective is to seek capital appreciation consistent with the Fund’s strategy and its primary objective. The Fund will attempt to achieve its objectives, under normal market conditions, by investing at least 80% of its assets in equity securities of companies principally engaged in the natural resources and gold industries. As part of its investment strategy, the Fund intends to generate current income from short term gains through an option strategy of writing (selling) covered call options of the equity securities in its portfolio. The Fund may invest in the securities of companies located anywhere in the world.

The Fund may invest a high percentage of its assets in specific sectors of the market in order to achieve a potentially greater investment return. As a result, the Fund may be more susceptible to economic, political, and regulatory developments in a particular sector of the market, positive or negative, and may experience increased volatility to the Fund’s NAV and a magnified effect in its total return.

2. Significant Accounting Policies. As an investment company, the Fund follows the investment company accounting and reporting guidance, which is part of U.S. generally accepted accounting principles (GAAP) that may require the use of management estimates and assumptions in the preparation of its financial statements. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.

The global outbreak of the novel coronavirus disease, known as COVID-19, has caused adverse effects on many companies, sectors, nations, regions and the markets in general, and may continue for an unpredictable duration. The effects of this pandemic may materially impact the value and performance of the Fund, its ability to buy and sell fund investments at appropriate valuations, and its ability to achieve its investment objectives.

Security Valuation. Portfolio securities listed or traded on a nationally recognized securities exchange or traded in the U.S. over-the-counter market for which market quotations are readily available are valued at the last quoted sale price or a market’s official closing price as of the close of business on the day the securities are being valued. If there were no sales that day, the security is valued at the average of the closing bid and asked prices or, if there were no asked prices quoted on that day, then the security is valued at the closing bid price on that day. If no bid or asked prices are quoted on such day, the security is valued at the most recently available price or, if the Board of Trustees (the Board) so determines, by such other method as the Board shall determine in good faith to reflect its fair market value. Portfolio securities traded on more than one national securities exchange or market are valued according to the broadest and most representative market, as determined by Gabelli Funds, LLC (the Adviser).

Portfolio securities primarily traded on a foreign market are generally valued at the preceding closing values of such securities on the relevant market, but may be fair valued pursuant to procedures established by the Board if market conditions change significantly after the close of the foreign market, but prior to the close of business on the day the securities are being valued. Debt obligations for which market quotations are readily available

GAMCO Natural Resources, Gold & Income Trust

Notes to Financial Statements (Unaudited) (Continued)

are valued at the average of the latest bid and asked prices. If there were no asked prices quoted on such day, the securities are valued using the closing bid price, unless the Board determines such amount does not reflect the securities’ fair value, in which case these securities will be fair valued as determined by the Board. Certain securities are valued principally using dealer quotations. Futures contracts are valued at the closing settlement price of the exchange or board of trade on which the applicable contract is traded. OTC futures and options on futures for which market quotations are readily available will be valued by quotations received from a pricing service or, if no quotations are available from a pricing service, by quotations obtained from one or more dealers in the instrument in question by the Adviser.

Securities and assets for which market quotations are not readily available are fair valued as determined by the Board. Fair valuation methodologies and procedures may include, but are not limited to: analysis and review of available financial and non-financial information about the company; comparisons with the valuation and changes in valuation of similar securities, including a comparison of foreign securities with the equivalent U.S. dollar value American Depositary Receipt securities at the close of the U.S. exchange; and evaluation of any other information that could be indicative of the value of the security.

The inputs and valuation techniques used to measure fair value of the Fund’s investments are summarized into three levels as described in the hierarchy below:

●

Level 1 — quoted prices in active markets for identical securities;

●

Level 2 — other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.); and

●

Level 3 — significant unobservable inputs (including the Board’s determinations as to the fair value of investments).

A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input both individually and in the aggregate that is significant to the fair value measurement. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The summary of the Fund’s investments in securities and other financial instruments by inputs used to value the Fund’s investments as of June 30, 2021 is as follows:

Additional Information to Evaluate Qualitative Information.

General. The Fund uses recognized industry pricing services – approved by the Board and unaffiliated with the Adviser – to value most of its securities, and uses broker quotes provided by market makers of securities not valued by these and other recognized pricing sources. Several different pricing feeds are received to value domestic equity securities, international equity securities, preferred equity securities, and fixed income securities. The data within these feeds are ultimately sourced from major stock exchanges and trading systems where these securities trade. The prices supplied by external sources are checked by obtaining quotations or actual transaction prices from market participants. If a price obtained from the pricing source is deemed unreliable, prices will be sought from another pricing service or from a broker/dealer that trades that security or similar securities.

Fair Valuation. Fair valued securities may be common or preferred equities, warrants, options, rights, or fixed income obligations. Where appropriate, Level 3 securities are those for which market quotations are not available, such as securities not traded for several days, or for which current bids are not available, or which are restricted as to transfer. When fair valuing a security, factors to consider include recent prices of comparable securities that are publicly traded, reliable prices of securities not publicly traded, the use of valuation models, current analyst reports, valuing the income or cash flow of the issuer, or cost if the preceding factors do not apply. A significant change in the unobservable inputs could result in a lower or higher value in Level 3 securities. The circumstances of Level 3 securities are frequently monitored to determine if fair valuation measures continue to apply.

The Adviser reports quarterly to the Board the results of the application of fair valuation policies and procedures. These may include backtesting the prices realized in subsequent trades of these fair valued securities to fair values previously recognized.

Derivative Financial Instruments. The Fund may engage in various portfolio investment strategies by investing in derivative financial instruments for the purposes of increasing the income of the Fund, hedging against changes in the value of its portfolio securities and in the value of securities it intends to purchase, or hedging against a specific transaction with respect to either the currency in which the transaction is denominated or another currency. Investing in certain derivative financial instruments, including participation in the options,

GAMCO Natural Resources, Gold & Income Trust

Notes to Financial Statements (Unaudited) (Continued)

futures, or swap markets, entails certain execution, liquidity, hedging, tax, and securities, interest, credit, or currency market risks. Losses may arise if the Adviser’s prediction of movements in the direction of the securities, foreign currency, and interest rate markets is inaccurate. Losses may also arise if the counterparty does not perform its duties under a contract, or, in the event of default, the Fund may be delayed in or prevented from obtaining payments or other contractual remedies owed to it under derivative contracts. The creditworthiness of the counterparties is closely monitored in order to minimize these risks. Participation in derivative transactions involves investment risks, transaction costs, and potential losses to which the Fund would not be subject absent the use of these strategies. The consequences of these risks, transaction costs, and losses may have a negative impact on the Fund’s ability to pay distributions.

Collateral requirements differ by type of derivative. Collateral requirements are set by the broker or exchange clearing house for exchange traded derivatives, while collateral terms are contract specific for derivatives traded over-the-counter. Securities pledged to cover obligations of the Fund under derivative contracts are noted in the Schedule of Investments. Cash collateral, if any, pledged for the same purpose will be reported separately in the Statement of Assets and Liabilities.

The Fund’s policy with respect to offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master agreement does not result in an offset of reported amounts of financial assets and financial liabilities in the Statement of Assets and Liabilities across transactions between the Fund and the applicable counterparty. The enforceability of the right to offset may vary by jurisdiction.

The Fund’s derivative contracts held at June 30, 2021, if any, are not accounted for as hedging instruments under GAAP and are disclosed in the Schedule of Investments together with the related counterparty.

Options. The Fund may purchase or write call or put options on securities or indices for the purpose of increasing the income of the Fund. As a writer of put options, the Fund receives a premium at the outset and then bears the risk of unfavorable changes in the price of the financial instrument underlying the option. The Fund would incur a loss if the price of the underlying financial instrument decreases between the date the option is written and the date on which the option is terminated. The Fund would realize a gain, to the extent of the premium, if the price of the financial instrument increases between those dates.

As a purchaser of put options, the Fund pays a premium for the right to sell to the seller of the put option the underlying security at a specified price. The seller of the put has the obligation to purchase the underlying security upon exercise at the exercise price. If the price of the underlying security declines, the Fund would realize a gain upon sale or exercise. If the price of the underlying security increases or stays the same, the Fund would realize a loss upon sale or at the expiration date, but only to the extent of the premium paid.

If a written call option is exercised, the premium is added to the proceeds from the sale of the underlying security in determining whether there has been a realized gain or loss. If a written put option is exercised, the premium reduces the cost basis of the security. In the case of call options, the exercise prices are referred to as “in-the-money,” “at-the-money,” and “out-of-the-money,” respectively. The Fund may write (a) in-the-money call options when the Adviser expects that the price of the underlying security will remain stable or decline during the option period, (b) at-the-money call options when the Adviser expects that the price of the underlying security will remain stable, decline, or advance moderately during the option period, and (c) out-of-the-money call options when the Adviser expects that the premiums received from writing the call option will be greater

GAMCO Natural Resources, Gold & Income Trust

Notes to Financial Statements (Unaudited) (Continued)

than the appreciation in the price of the underlying security above the exercise price. By writing a call option, the Fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option. Out-of-the-money, at-the-money, and in-the-money put options (the reverse of call options as to the relation of exercise price to market price) may be utilized in the same market environments that such call options are used in equivalent transactions. Option positions at June 30, 2021 are reflected within the Schedule of Investments.

The Fund’s volume of activity in equity options contracts during the six months ended June 30, 2021 had an average monthly market value of approximately $9,943,489.

As of June 30, 2021, the value of equity options written can be found in the Statement of Assets and Liabilities, under Liabilities, options written, at value. For the six months ended June 30, 2021, the effect of equity options written can be found in the Statement of Operations under Net Realized and Unrealized Gain/(Loss) on Investments, Securities Sold Short, Written Options, and Foreign Currency, within Net realized gain on written options, and Net change in unrealized appreciation/(depreciation) on written options.

Limitations on the Purchase and Sale of Futures Contracts, Certain Options, and Swaps. Subject to the guidelines of the Board, the Fund may engage in “commodity interest” transactions (generally, transactions in futures, certain options, certain currency transactions, and certain types of swaps) only for bona fide hedging or other permissible transactions in accordance with the rules and regulations of the Commodity Futures Trading Commission (CFTC). Pursuant to amendments by the CFTC to Rule 4.5 under the Commodity Exchange Act (CEA), the Adviser has filed a notice of exemption from registration as a “commodity pool operator” with respect to the Fund. The Fund and the Adviser are therefore not subject to registration or regulation as a commodity

GAMCO Natural Resources, Gold & Income Trust

Notes to Financial Statements (Unaudited) (Continued)

pool operator under the CEA. In addition, certain trading restrictions are now applicable to the Fund which permit the Fund to engage in commodity interest transactions that include (i) “bona fide hedging” transactions, as that term is defined and interpreted by the CFTC and its staff, without regard to the percentage of the Fund’s assets committed to margin and options premiums and (ii) non-bona fide hedging transactions, provided that the Fund does not enter into such non-bona fide hedging transactions if, immediately thereafter, either (a) the sum of the amount of initial margin deposits on the Fund’s existing futures positions or swaps positions and option or swaption premiums would exceed 5% of the market value of the Fund’s liquidating value, after taking into account unrealized profits and unrealized losses on any such transactions, or (b) the aggregate net notional value of the Fund’s commodity interest transactions would not exceed 100% of the market value of the Fund’s liquidating value, after taking into account unrealized profits and unrealized losses on any such transactions. Therefore, in order to claim the Rule 4.5 exemption, the Fund is limited in its ability to invest in commodity futures, options, and certain types of swaps (including securities futures, broad based stock index futures, and financial futures contracts). As a result, in the future the Fund will be more limited in its ability to use these instruments than in the past, and these limitations may have a negative impact on the ability of the Adviser to manage the Fund, and on the Fund’s performance.

Securities Sold Short. The Fund may enter into short sale transactions. Short selling involves selling securities that may or may not be owned and, at times, borrowing the same securities for delivery to the purchaser, with an obligation to replace such borrowed securities at a later date. The proceeds received from short sales are recorded as liabilities and the Fund records an unrealized gain or loss to the extent of the difference between the proceeds received and the value of an open short position on the day of determination. The Fund records a realized gain or loss when the short position is closed out. By entering into a short sale, the Fund bears the market risk of an unfavorable change in the price of the security sold short. Dividends on short sales are recorded as an expense by the Fund on the ex-dividend date and interest expense is recorded on the accrual basis. The broker retains collateral for the value of the open positions, which is adjusted periodically as the value of the position fluctuates. For the six months ended June 30, 2021, the Fund incurred $3,432 in service fees related to its investment positions sold short and held by the broker. These amounts are included in the Statement of Operations under Expenses, Service fees for securities sold short.

Investments in Other Investment Companies. The Fund may invest, from time to time, in shares of other investment companies (or entities that would be considered investment companies but are excluded from the definition pursuant to certain exceptions under the 1940 Act) (the Acquired Funds) in accordance with the 1940 Act and related rules. Shareholders in the Fund would bear the pro rata portion of the periodic expenses of the Acquired Funds in addition to the Fund’s expenses. For the six months ended June 30, 2021, the Fund’s pro rata portion of the periodic expenses charged by the Acquired Funds was less than one basis point.

Foreign Currency Translations. The books and records of the Fund are maintained in U.S. dollars. Foreign currencies, investments, and other assets and liabilities are translated into U.S. dollars at current exchange rates. Purchases and sales of investment securities, income, and expenses are translated at the exchange rate prevailing on the respective dates of such transactions. Unrealized gains and losses that result from changes in foreign exchange rates and/or changes in market prices of securities have been included in unrealized appreciation/depreciation on investments and foreign currency translations. Net realized foreign currency gains and losses resulting from changes in exchange rates include foreign currency gains and losses between trade

GAMCO Natural Resources, Gold & Income Trust

Notes to Financial Statements (Unaudited) (Continued)

date and settlement date on investment securities transactions, foreign currency transactions, and the difference between the amounts of interest and dividends recorded on the books of the Fund and the amounts actually received. The portion of foreign currency gains and losses related to fluctuation in exchange rates between the initial purchase trade date and subsequent sale trade date is included in realized gain/(loss) on investments.

Foreign Securities. The Fund may directly purchase securities of foreign issuers. Investing in securities of foreign issuers involves special risks not typically associated with investing in securities of U.S. issuers. The risks include possible revaluation of currencies, the inability to repatriate funds, less complete financial information about companies, and possible future adverse political and economic developments. Moreover, securities of many foreign issuers and their markets may be less liquid and their prices more volatile than securities of comparable U.S. issuers.

Foreign Taxes. The Fund may be subject to foreign taxes on income, gains on investments, or currency repatriation, a portion of which may be recoverable. The Fund will accrue such taxes and recoveries as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.

Restricted Securities. The Fund may invest up to 15% of its net assets in securities for which the markets are restricted. Restricted securities include securities whose disposition is subject to substantial legal or contractual restrictions. The sale of restricted securities often requires more time and results in higher brokerage charges or dealer discounts and other selling expenses than the sale of securities eligible for trading on national securities exchanges or in the over-the-counter markets. Restricted securities may sell at a price lower than similar securities that are not subject to restrictions on resale. Securities freely saleable among qualified institutional investors under special rules adopted by the SEC may be treated as liquid if they satisfy liquidity standards established by the Board. The continued liquidity of such securities is not as well assured as that of publicly traded securities, and accordingly the Board will monitor their liquidity. At June 30, 2021, the Fund held no restricted securities.

Securities Transactions and Investment Income. Securities transactions are accounted for on the trade date with realized gain/(loss) on investments determined by using the identified cost method. Interest income (including amortization of premium and accretion of discount) is recorded on an accrual basis. Premiums and discounts on debt securities are amortized using the effective yield to maturity method or amortized to earliest call date, if applicable. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities that are recorded as soon after the ex-dividend date as the Fund becomes aware of such dividends.

Custodian Fee Credits and Interest Expense. When cash balances are maintained in the custody account, the Fund receives credits which are used to offset custodian fess. The gross expenses paid under the custody arrangement are included in custodian fees in the Statement of Operations with the corresponding expense offset, if any, shown as “Custodian fee credits.” When cash balances are overdrawn, the Fund is charged an overdraft fee of 110% of the 90 day U.S. Treasury Bill rate on outstanding balances. This amount, if any, would be included in the Statement of Operations.

Distributions to Shareholders. Distributions to common stockholders are recorded on the ex-dividend date. Distributions to stockholders are based on income and capital gains as determined in accordance with federal income tax regulations, which may differ from income and capital gains as determined under GAAP. These

GAMCO Natural Resources, Gold & Income Trust

Notes to Financial Statements (Unaudited) (Continued)

differences are primarily due to differing treatments of income and gains on various investment securities and foreign currency transactions held by the Fund, timing differences, and differing characterizations of distributions made by the Fund. Distributions from net investment income for federal income tax purposes include net realized gains on foreign currency transactions. These book/tax differences are either temporary or permanent in nature. To the extent these differences are permanent, adjustments are made to the appropriate capital accounts in the period when the differences arise. These reclassifications have no impact on the NAV of the Fund.

The Fund declares and pays monthly distributions from net investment income, capital gains, and paid-in capital. The actual source of the distribution is determined after the end of the year. Distributions during the year may be made in excess of required distributions. Distributions sourced from paid-in capital should not be considered as dividend yield or the total return from an investment in the Fund. The Board will continue to monitor the Fund’s distribution level, taking into consideration the Fund’s NAV and the financial market environment. The Fund’s distribution policy is subject to modification by the Board at any time.

Distributions to shareholders of the Fund’s 5.200% Series A Cumulative Preferred Shares (Series A Preferred) are accrued on a daily basis and are determined as described in Note 5.

The tax character of distributions paid during the year ended December 31, 2020 was as follows:

	Common		Preferred
Distributions paid from:
Ordinary income		—	$	1,067,709
Return of capital	$	9,924,203		454,406
Total distributions paid	$	9,924,203	$	1,522,115

Provision for Income Taxes. The Fund intends to continue to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended (the Code). It is the policy of the Fund to comply with the requirements of the Code applicable to regulated investment companies and to distribute substantially all of its net investment company taxable income and net capital gains. Therefore, no provision for federal income taxes is required.

At December 31, 2020, the Fund had net long term capital loss carryforwards for federal income tax purposes which are available to reduce future required distributions of net capital gains to shareholders for an unlimited period. These capital losses will retain their character as short term or long term capital losses.

GAMCO Natural Resources, Gold & Income Trust

Notes to Financial Statements (Unaudited) (Continued)

The Fund is required to evaluate tax positions taken or expected to be taken in the course of preparing the Fund’s tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Income tax and related interest and penalties would be recognized by the Fund as tax expense in the Statement of Operations if the tax positions were deemed not to meet the more-likely-than-not threshold. During the six months ended June 30, 2021, the Fund did not incur any income tax, interest, or penalties. As of June 30, 2021, the Adviser has reviewed all open tax years and concluded that there was no impact to the Fund’s net assets or results of operations. The Fund’s federal and state tax returns for the prior three fiscal years remain open, subject to examination. On an ongoing basis, the Adviser will monitor the Fund’s tax positions to determine if adjustments to this conclusion are necessary.

3. Investment Advisory Agreement and Other Transactions. The Fund has entered into an investment advisory agreement (the Advisory Agreement) with the Adviser which provides that the Fund will pay the Adviser a fee, computed weekly and paid monthly, equal on an annual basis to 1.00% of the value of the Fund’s average weekly net assets including the liquidation value of preferred shares. In accordance with the Advisory Agreement, the Adviser provides a continuous investment program for the Fund’s portfolio and oversees the administration of all aspects of the Fund’s business and affairs.

During the six months ended June 30, 2021, the Fund received credits from a designated broker who agreed to pay certain Fund operating expenses. The amount of such expenses paid through this directed brokerage arrangement during this period was $1,073.

The cost of calculating the Fund’s NAV per share is a Fund expense pursuant to the Advisory Agreement between the Fund and the Adviser. Under the sub-administration agreement with Bank of New York Mellon, the fees paid include the cost of calculating the Fund’s NAV. The Fund reimburses the Adviser for this service. During the six months ended June 30, 2021, the Fund accrued $22,500 in accounting fees in the Statement of Operations.

As per the approval of the Board, the Fund compensates officers of the Fund, who are employed by the Fund and are not employed by the Adviser (although the officers may receive incentive based variable compensation from affiliates of the Adviser). During the six months ended June 30, 2021, the Fund accrued $58,723 in Payroll expenses in the Statement of Operations.

The Fund pays retainer and per meeting fees to Trustees not affiliated with the Adviser, plus specified amounts to the Lead Trustee and Audit Committee Chairman. Trustees are also reimbursed for out of pocket expenses incurred in attending meetings. Trustees who are directors or employees of the Adviser or an affiliated company receive no compensation or expense reimbursement from the Fund.

4. Portfolio Securities. Purchases and sales of securities during the six months ended June 30, 2021, other than short term securities and U.S. Government obligations, aggregated $86,755,499 and $81,137,102, respectively.

5. Capital. The Fund is authorized to issue an unlimited number of common shares of beneficial interest (par value $0.001). The Board has authorized the repurchase of its shares in the open market when the shares are trading at a discount of 10% or more (or such other percentage as the Board may determine from time to time) from the NAV of the shares. During the six months ended June 30, 2021 and the year ended December

GAMCO Natural Resources, Gold & Income Trust

Notes to Financial Statements (Unaudited) (Continued)

31, 2020, the Fund repurchased and retired 859,964 and 1,082,741, respectively, of its common shares at an investment of $4,451,331 and $5,416,574, respectively, and an average discount of approximately 13.08% and 14.70%, respectively, from its NAV.

Transactions in common shares of beneficial interest for the six months ended June 30, 2021 and the year ended December 31, 2020, respectively were as follows:

	Six Months Ended
	June 30, 2021						Year Ended
	(Unaudited)						December 31, 2020
	Shares			Amount			Shares			Amount
Net increase in net assets from common shares issued in offering		—			—			13,820		$	82,569

Net decrease		(859,964	)		(4,451,331	)		(1,068,921	)	$	(5,334,005	)

The Fund has an effective shelf registration authorizing the issuance of $200 million in common or preferred shares.

The Fund’s Declaration of Trust, as amended, authorizes the issuance of an unlimited number of $0.001 par value Preferred Shares. On October 26, 2017, the Fund issued 1,200,000 shares of 5.200% Series A Cumulative Preferred Shares (Series A Preferred), receiving $28,851,132, after the deduction of offering expenses of $203,868 and underwriting fees of $945,000. The Series A Preferred has a liquidation value of $25 per share, an annual dividend rate of 5.200%, and is noncallable before October 26, 2022. The Board has authorized the repurchase of the Series A Preferred in the open market at prices less than $25 liquidation value per share. During the year ended December 31, 2020, the Fund repurchased and retired 3,200 of the Series A Preferred shares in the open market at an investment of $70,473 and an average discount of approximately 11.95% from its liquidation preference, respectively. The Fund did not repurchase any Preferred Shares in 2021. At June 30, 2021, 1,170,102 shares were outstanding and accrued dividends amounted to $21,127.

The Series A Preferred is senior to the common shares and results in the financial leveraging of the common shares. Such leveraging tends to magnify both the risks and opportunities to common shareholders. Dividends on the Series A Preferred are cumulative. The Fund is required by the 1940 Act and by the Statement of Preferences to meet certain asset coverage tests with respect to the Series A Preferred. If the Fund fails to meet these requirements and does not correct such failure, the Fund may be required to redeem, in part or in full, the Series A Preferred at the redemption price of $25 per share plus an amount equal to the accumulated and unpaid dividends whether or not declared on such shares in order to meet the requirements. Additionally, failure to meet the foregoing asset coverage requirements could restrict the Fund’s ability to pay dividends to common shareholders and could lead to sales of portfolio securities at inopportune times. The income received on the Fund’s assets may vary in a manner unrelated to the fixed rate, which could have either a beneficial or detrimental impact on net investment income and gains available to common shareholders.

The holders of Preferred Shares generally are entitled to one vote per share held on each matter submitted to a vote of shareholders of the Fund and will vote together with holders of common shares as a single class. The

GAMCO Natural Resources, Gold & Income Trust

Notes to Financial Statements (Unaudited) (Continued)

holders of Preferred Shares voting together as a single class also have the right currently to elect two Trustees and, under certain circumstances, are entitled to elect a majority of the Board of Trustees. In addition, the affirmative vote of a majority of the votes entitled to be cast by holders of all outstanding shares of the Preferred Shares, voting as a single class, will be required to approve any plan of reorganization adversely affecting the Preferred Shares, and the approval of two-thirds of each class, voting separately, of the Fund’s outstanding voting shares must approve the conversion of the Fund from a closed-end to an open-end investment company. The approval of a majority (as defined in the 1940 Act) of the outstanding Preferred Shares and a majority (as defined in the 1940 Act) of the Fund’s outstanding voting securities are required to approve certain other actions, including changes in the Fund’s investment objectives or fundamental investment policies.

6. Indemnifications. The Fund enters into contracts that contain a variety of indemnifications. The Fund’s maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts. Management has reviewed the Fund’s existing contracts and expects the risk of loss to be remote.

7. Subsequent Events. Management has evaluated the impact on the Fund of all subsequent events occurring through the date the financial statements were issued and has determined that there were no subsequent events requiring recognition or disclosure in the financial statements.

GAMCO Natural Resources, Gold & Income Trust

Certifications

The Fund’s Chief Executive Officer has certified to the New York Stock Exchange (NYSE) that, as of June 7, 2021, he was not aware of any violation by the Fund of applicable NYSE corporate governance listing standards. The Fund reports to the SEC on Form N-CSR which contains certifications by the Fund’s principal executive officer and principal financial officer that relate to the Fund’s disclosure in such reports and that are required by Rule 30a-2(a) under the 1940 Act.

Shareholder Meeting – May 10, 2021 – Final Results

The Fund’s Annual Meeting of Shareholders was held virtually on May 10, 2021. At that meeting, common and preferred shareholders, voting together as a single class, re-elected Anthony S. Colavita, Frank J. Fahrenkopf, Jr., and William F. Heitmann as Trustees of the Fund, with a total 14,949,382 votes, 14,880,430 votes, and 14,903,271 in favor of these Trustees, and a total of 504,106 votes, 573,058 votes, and 550,217 votes withheld for these Trustees, respectively.

In addition, preferred shareholders, voting as a separate class, re-elected Salvatore J. Zizza as a Trustee of the Fund, with 929,094 votes cast in favor of this Trustee and 28,937 votes withheld for this Trustee.

James P. Conn, Vincent D. Enright, Kuni Nakamura, Michael J. Melarkey, Agnes Mullady, and Anthonie C. van Ekris continue to serve in their capacities as Trustees of the Fund.
