**EXPLANATORY NOTE**

Electra Battery Materials Corporation (the "Company") is filing this Amendment No. 1 ("Amendment No. 1") to its Registration Statement on Form F-3, originally filed on June 27, 2025 (the "Original Filing") solely for the purposes of (i) adding signatures from certain members of the Company's Board of Directors, and (ii) to add a new Exhibit 5.2. Accordingly, this Amendment No. 1 consists only of the facing page, this explanatory note, Part II of the Registration Statement, including the signature page and the exhibit index, and the filed exhibits. The prospectuses are unchanged and have been omitted.

**PART II**

#### INFORMATION NOT REQUIRED IN PROSPECTUS
**Indemnification of Directors and Officers**

Under the Canada Business Corporations Act (the "**CBCA**"), we may indemnify our current or former directors or officers or another individual who acts or acted at our request as a director or officer, or an individual acting in a similar capacity, of another entity, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other proceeding in which the individual is involved because of his or her association with us or another entity. The CBCA also provides that we may advance moneys to a director, officer or other individual for costs, charges and expenses reasonably incurred in connection with such a proceeding; provided that such individual shall repay the moneys if the individual does not fulfill the conditions described below.

However, indemnification is prohibited under the CBCA unless the individual:

&nbsp;&nbsp;&nbsp;&nbsp;· acted honestly and in good faith with a view to our best interests, or the best interests of the other entity for which the individual
 acted as director or officer or in a similar capacity at our request; and

&nbsp;&nbsp;&nbsp;&nbsp;· in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, the
 individual had reasonable grounds for believing that his or her conduct was lawful.

Our by-laws require us to indemnify to the fullest extent permitted by the CBCA each of our current or former directors or officers and each individual who acts or acted at our request as a director or officer, or an individual acting in a similar capacity, of another entity, against all costs, charges and expenses, including, without limitation, an amount paid to settle an action or satisfy a judgment, reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other proceeding in which the individual is involved because of his or her association with us or another entity.

Our by-laws authorize us to purchase and maintain insurance for the benefit of each of our current or former directors or officers and each person who acts or acted at our request as a director or officer, or an individual acting in a similar capacity, of another entity provided the individual acted in that capacity at our request.

**Insofar as indemnification for liabilities arising under the U.S. Securities Act of 1933, as amended, may be permitted to directors, officers or persons controlling the Registrant pursuant to the foregoing provisions, the Registrant has been informed that in the opinion of the U.S. Securities and Exchange Commission such indemnification is against public policy as expressed in the U.S. Securities Act of 1933, as amended, and is therefore unenforceable.**

#### UNDERTAKINGS
(a) The undersigned registrant hereby undertakes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement
 (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information
 set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the
 total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the
 estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the
 aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth
 in the "Calculation of Registration Fee" table in the effective registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) To include any material information with respect to the plan of distribution not previously disclosed in the
 registration statement or any material change to such information in the registration statement;

Provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the registration statement is on Form S-3 or Form F-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) To file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A. of Form 20-F at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Securities Act of 1933 need not be furnished, provided, that the registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph (a)(4) and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, with respect to registration statements on Form F-3, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Securities Act of 1933 or Rule 3-19 of Regulation S-X if such financial statements and information are contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Form F-3.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration
 statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration
 statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing
 the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration
 statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of
 sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any
 person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating
 to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall
 be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus
 that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration
 statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such
 effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration
 statement or made in any such document immediately prior to such effective date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to
 be filed pursuant to Rule 424;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant
 or used or referred to by the undersigned registrant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) The portion of any other free writing prospectus relating to the offering containing material information
 about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities
 Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of
 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities
 Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement
 relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide
 offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors,
 officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised
 that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities
 Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment
 by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense
 of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being
 registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to
 a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities
 Act of 1933 and will be governed by the final adjudication of such issue.

#### SIGNATURES
Pursuant to the requirements of the Securities Act of 1933, as amended, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form F-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Toronto, Country of Canada, on July 25, 2025.

Dear Sirs/Mesdames:

| **Re:** | **Electra Battery Materials Corporation - Registration Statement on Form F-3** |

---

We have acted as Canadian counsel to Electra Battery Materials Corporation, a corporation existing under the laws of Canada (the "**Company**"). We are furnishing this opinion in connection with the at-the-market offering by the Company of common shares of the Company for up to US$5,500,000 (the "**Common Shares**") pursuant to a registration statement on Form F-3, Registration File No. 333-288364 (the "**Registration Statement**"), filed by the Company with the U.S. Securities and Exchange Commission, including a base prospectus (the "**Base Prospectus**"), and a prospectus supplement to the Base Prospectus (the "**Prospectus Supplement**", and, together with the Base Prospectus, the "**Prospectus**"). The Common Shares are to be sold in the United States through H.C. Wainwright & Co., LLC (the "**Sales Agent**") from time to time by the Company pursuant to the Registration Statement, Prospectus and that certain At The Market Offering Agreement dated June 26, 2025 by and between the Sales Agent and the Company (the "**ATM Agreement**").

In so acting, we have examined copies of the Registration Statement, including the Prospectus contained therein, as well as the following documents (collectively, the "**Corporate Documents**"): (i) the Company's Articles of Incorporation and Bylaws and (ii) records of the Company's corporate proceedings in connection with the Registration Statement and the Prospectus. We have also examined copies, certified or otherwise identified to our satisfaction, of such public and corporate records, certificates, instruments and other documents and have considered such questions of law as we have deemed relevant and necessary as a basis for the opinion hereinafter expressed. With respect to the accuracy of factual matters material to this opinion, we have relied upon certificates or comparable documents and representations of public officials and the Corporate Documents, without independent investigation of the matters provided for therein for the purpose of providing this opinion.

In examining all documents and in providing our opinion, we have assumed:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) all
 information contained in all documents reviewed by us is true and correct;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the
 genuineness of all signatures on all documents examined by us and the legal capacity of all natural persons;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) the
 authenticity of all documents submitted to us as originals;

![](footerca.jpg)

![](casselslogo.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the
 conformity to original documents of all documents submitted to us as copies, whether facsimile, electronic, photostatic, certified
 or otherwise, and the authenticity of the originals of such copies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) each
 natural person signing any document reviewed by us had the legal capacity to do so, none of which facts we have independently verified;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) no
 order, ruling or decision of any court or regulatory or administrative body is in effect at any relevant time that restricts the
 issuance of the Common Shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) there
 is no foreign law that would affect the opinion expressed herein;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) at
 the time of the execution and delivery of any documents relating to the Common Shares or the offering thereof, to the extent such
 documents purport to constitute agreements, such documents constitute valid and binding obligations of such parties;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the
 due authorization, execution and delivery of all documents where authorization, execution and delivery are prerequisites to the effectiveness
 of such documents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) the
 Company has the necessary corporate power and capacity to execute, deliver and perform its obligations under the terms and conditions
 of the ATM Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) the
 Company has the necessary corporate power and capacity to authorize, create, authenticate, validly issue, sell and deliver the Common
 Shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) all
 necessary corporate action has been taken by the Company to duly authorize the execution and delivery by the Company of the ATM Agreement
 and the performance of its obligations under the terms and conditions thereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m) all
 necessary corporate action has been taken by the Company to duly authorize, create, authenticate, sell, deliver and validly issue
 the Common Shares, and all of the terms and conditions relevant to the execution, delivery and issuance of the Common Shares in the
 ATM Agreement have been complied with;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(n) all
 necessary corporate action has been taken by the Company to duly authorize the terms of the offering of the Common Shares and related
 matters;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(o) the
 ATM Agreement (i) has been duly authorized, executed and delivered by all parties thereto and such parties had the capacity to do
 so; (ii) constitutes a legal, valid and binding obligation of all parties thereto; (iii) is enforceable in accordance with
 its terms against all parties thereto; and (iv) is governed by the laws of the State of New York;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(p) the
 Common Shares have been duly authorized, created, authenticated, sold and delivered and validly issued by the Company and any other
 person signing or authenticating the Common Shares, as applicable;

![](casselslogo.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(q) the
 execution and delivery of the ATM Agreement and the performance by the Company of its obligations under the terms and conditions
 thereunder do not and will not conflict with and do not and will not result in a breach of or default under, and do not and will
 not create a state of facts which, after notice or lapse of time or both, will conflict with or result in a breach of or default
 under any of the terms or conditions of the notice of articles or articles of the Company, any resolutions of the board of directors
 or shareholders of the Company, any agreement or obligation of the Company, or applicable law;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(r) the
 authorization, creation, authentication, sale, delivery and issuance of the Common Shares do not and will not conflict with and do
 not and will not result in a breach of or default under, and do not and will not create a state of facts which, after notice or lapse
 of time or both, will conflict with or result in a breach of or default under any of the terms or conditions of the notice of articles
 or articles of the Company, any resolutions of the board of directors or shareholders of the Company, any agreement or obligation
 of the Company, or applicable law; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(s) the
 terms of the offering of the Common Shares and related matters do not conflict with and do not result in a breach of or default under,
 and do not create a state of facts which, after notice or lapse of time or both, will conflict with or result in a breach of or default
 under any of the terms or conditions of the notice of articles or articles of the Company, any resolutions of the board of directors
 or shareholders of the Company, any agreement or obligation of the Company, or applicable law.

Our opinion herein is limited to the laws of the Province of Ontario and the federal laws of Canada applicable therein now in effect on the date hereof (the "**Applicable Law**"), and we are expressing no opinion as to the effect of the laws of any other jurisdiction, domestic or foreign.

Based and relying upon the foregoing, and subject to the qualifications, assumptions and limitations expressed herein, we are of the opinion that on the date hereof, the Common Shares, when issued, sold and delivered in the manner and for the consideration set forth in, and in accordance with the ATM Agreement and the Corporate Documents, upon payment of the consideration provided therein to the Company, will be validly issued as fully paid and non-assessable common shares in the capital of the Company.

We hereby consent to the use of our name under the heading "Legal Matters" in, and the filing of this opinion as an exhibit to, the Registration Statement. In giving this consent, we do not thereby admit that we are in the category of persons whose consent is required under the Securities Act of 1933, as amended, or the rules and regulations promulgated thereunder.

This opinion is furnished solely in connection with the filing of the Registration Statement and is not to be used, circulated, quoted or otherwise relied upon for any other purpose. This opinion is limited to the specific issues addressed herein, and no opinion may be inferred or implied beyond that expressly stated herein. This opinion is expressed as at the date hereof and we disclaim any undertaking or obligation to advise you of any subsequent changes of the facts stated or assumed herein or any subsequent changes in Applicable Law.

Yours truly,
