Horizonte Minerals Plc (AIM: HZM, TSX:HZM) (" Horizonte ", the " Company " or the " Group "), the nickel development company focused on Brazil is pleased to announce a proposed fundraising (the " Fundraise ") to raise gross proceeds of approximately US$25.0 million (approximately £18.0 million C$31.7 million) at a price of 7.5 pence per Placing Share (C$0.133) (the " Placing Price "). The Fundraise comprises: (i) a placing to new and existing institutional investors (the " Placing "), and (ii) a concurrent underwritten bought deal private placement (the " Canadian Offering ") to be led by Paradigm Capital Inc.(" Paradigm ").

Cantor Fitzgerald Canada Corporation (" Cantor "), Peel Hunt LLP (" Peel Hunt ") and BMO Capital Markets Limited (" BMO ") (Cantor, together with Peel Hunt and BMO, being the " Joint Bookrunners ") are acting as joint bookrunners in relation to the Placing. Paradigm is acting as the sole bookrunner in relation to the Canadian Offering.

Highlights

• The net proceeds of the Fundraise will be used to initiate specific early works and advance long-lead time items linked to the start of construction of the Company's Araguaia ferro-nickel project in Brazil (" Araguaia " or the " Project "), as well as for general working capital purposes.
• The Araguaia FeNi project is a high grade, low cost, long life asset located south of the Carajàs Mining District, north east Brazil. The feasibility study demonstrates robust economics with the Stage 1 process plant producing 14,500 tonnes of nickel per year, Post-tax IRR: 27.0%, Post-tax NPV(8%): US$691m, Payback Period: 3 years, Net Cashflow: US$2.4bn based on a nickel price of US$16,400 per tonne.
• The Company has a second 100% owned project, the Vermelho Nickel Cobalt project which is being advanced towards feasibility stage with aim of producing nickel and cobalt sulphate for the EV battery market.
• Strong long-term outlook for the nickel market driven by acceleration in the EV battery sector and steady growth in stainless steel demand. 43.7% increase in the Nickel price in the last 12 months to 18 February 2021 reflects increased demand from China. Global demand of 2.29 Mt in 2020 expected to grow between 2 and 5 per cent. annually to reach 4.16 Mt in 2040. The spot nickel price is currently US$18,720 per tonne.
• Good progress continues to be made on the Project Finance process for Araguaia with a syndicate of lending banks (being BNP Paribas, ING Capital LLC, Mizuho Bank, Ltd., Natixis, New York Branch and Société Générale) to arrange a senior secured project finance facility of up to US$325 million (the " Project Finance Facility ") to part-fund the construction and development of the Project.
• The Company anticipates the full project financing package will be completed in H1 2021, with construction commencing shortly thereafter.

The Placing is being conducted through an accelerated bookbuild process (the " Bookbuild ") which will be launched immediately following release of this Announcement (as defined below). The timing of the closing of the Bookbuild and the allocations are at the absolute discretion of the Joint Bookrunners and the Company. The results of the Placing will be announced as soon as practicable after the close of the Bookbuild. The Company has also today entered into an agreement (the " Bought Deal Letter "), with Paradigm, on its own behalf and on behalf of a syndicate of underwriters, pursuant to which the underwriters have agreed to purchase 76,574,000 of special warrants (the " Special Warrants ") at the Placing Price, which entitle the holder thereof to receive, without payment of additional consideration, one ordinary share of £0.01 each, to be exercised pursuant to the terms described below under the heading "The Canadian Offering". The new ordinary shares of £0.01 (the " Ordinary Shares ") each issued pursuant to the Placing (the " Placing Shares ") and the Ordinary Shares to be issued upon conversion of the Special Warrants, when issued, will be issued as fully paid and will rank pari passu in all respects with each other and with the existing Ordinary Shares from their admission to trading on AIM.

The Placing is subject to the terms and conditions set out in the Appendix to this announcement (which forms part of this announcement, such announcement and the Appendix together being this " Announcement ").

Background to and reasons for the Fundraise

Horizonte has continued to make good progress with regards to debt and strategic financing as well as in respect of offtake discussions for the Araguaia Project. The nickel market has shown its strength, driven by a recovery in the Chinese economy leading to increased demand for stainless steel as well as anticipated demand from the burgeoning EV battery market. In turn, the Company has seen an increased interest from investors due to Araguaia's robust economics, low capital intensity and location in a world class mining district. The Fundraise will inter alia strengthen the Company's balance sheet as it enters a critical phase of financing discussions, enable the Company to commence certain pre-construction expenditures and provide working capital to the group.

Horizonte wholly owns both the advanced Araguaia nickel project and the Vermelho nickel-cobalt project, located in the south of the Carajàs mineral district in northern Brazil. A feasibility study for Araguaia was published in October 2018. The study demonstrated the robust economics of Araguaia.

Ore will be sourced from eight open pits, with a targeted 0.9mt per annum of ore to a central processing and smelting facility. A 28-year production schedule is envisaged with a 31 month construction period followed by initial ramp up to full scale commercial production. Key economic highlights of the Project are as follows:

• Highly cash generative: approximately US$2.4 billion net cash flow
• Post-tax NPV(8%) of US$691million
• Post-tax IRR of 27.0%
• Payback of approx. 3.0 years
• Low Capital Intensity – US$443 million capital cost
• Lowest quartile cash cost (years 1-10) of US$6,794 /t Ni

Vermelho was acquired from Vale SA and is a nickel cobalt project, located approximately 80 kilometres north west of the Company's Araguaia North ferronickel project. A pre-feasibility study representing the economics of developing Vermelho was released in October 2019. These two projects located within close proximity of each other create a large, high-grade flexible resource base with the combined potential to produce 50,000 tonnes of nickel per year.

On 12 August 2020 the Company announced it had mandated a syndicate of banks (being BNP Paribas, ING Capital LLC, Mizuho Bank, Ltd., Natixis, New York Branch and Société Générale) to arrange the US$325 million Project Finance Facility to part-fund the construction and development of Araguaia. In addition, the Company recently negotiated a non-binding term sheet with a major cornerstone equity investor while discussions with potential offtakers have progressed. The Company anticipates the full project financing package for Araguaia will be completed in H1 2021, with construction commencing shortly thereafter.

The proceeds of the Placing will, in addition to the Company's cash balance of £10.9 million as at 31 December 2020, enable the Company to commence initial plans for construction of Araguaia, improve the Company's balance sheet ensuring that it enters the next, critical phase of financing from a strong position and creates the opportunity to broaden the Company's shareholder base through the introduction of new investors. The proceeds of the Canadian Offering, if and when received, will also be used for this purpose.

Details of the Placing

The Joint Bookrunners will commence the Bookbuild immediately following the release of this Announcement in respect of the Placing. The book will open with immediate effect following this Announcement. The timing of the closing of the book and allocations are at the absolute discretion of the Joint Bookrunners, in consultation with the Company.

The results of the Placing will be announced as soon as practicable after the close of the Bookbuild. The Placing is subject to the terms and conditions set out in the appendix (the " Appendix ") to this announcement (which forms part of this announcement, such announcement and the Appendix together being this " Announcement ") .

The Placing is not conditional upon completion of the Canadian Offering or the issue of Ordinary Shares upon conversion of the Special Warrants. The Joint Bookrunners may (but are not obliged to) terminate the Placing Agreement, if prior to admission of the Placing Shares the Canadian Offering terminates. The Placing is not being underwritten by the Joint Bookrunners and is subject to the conditions and termination rights set out in the Placing Agreement between the Company and the Joint Bookrunners. The completion of the Placing is conditional upon, inter alia, admission of the Placing Shares to trading on AIM and receipt of conditional approval of the Toronto Stock Exchange. The Placing Shares, if issued, will be fully paid and will rank pari passu in all respects with each other and with the existing Ordinary Shares, including the right to receive all dividends and other distributions declared, made or paid on or in respect of the Ordinary Shares after the date of issue of the Placing Shares.

The Company acknowledges that it is seeking to issue Placing Shares on a non pre-emptive basis and has therefore consulted, where possible, with the Company's major shareholders ahead of this Announcement. The Fundraise structure has been chosen as it minimises cost, time to completion and use of management time. The consultation has confirmed the Board's view that the Fundraise is in the best interests of shareholders, as well as wider stakeholders in the Company.

The Canadian Offering

The Company has also today entered into the Bought Deal Letter, with Paradigm, on its own behalf and on behalf of a syndicate of underwriters, pursuant to which the underwriters have agreed to purchase 76,574,000 of Special Warrants at the Placing Price. In addition, the Company has granted Paradigm an option (the " Underwriters' Option ") to purchase an additional 11,486,100 Special Warrants at the Placing Price, exercisable up to 48 hours prior to the Closing Date (as defined herein) for additional gross proceeds to the Company of C$1.5 million. The terms "Canadian Offering" and "Special Warrants" include the additional Special Warrants that may be issued on the exercise of the Underwriters' Option, if any. Each Special Warrant will be issued under a special warrant indenture and will entitle the holder thereof to receive, without payment of additional consideration, one Ordinary Share. The Special Warrants shall be deemed exercised on behalf of, and without any required action on the part of, the holders (including payment of additional consideration) on the earlier of:

(i) the third business day following the date on which a final receipt (the " Prospectus Receipt ") is obtained from the Ontario Securities Commission, as principal regulator on behalf of the securities regulatory authorities in each of the territories and provinces of Canada (other than Quebec), for a (final) short form prospectus qualifying the Ordinary Shares for distribution (the " Qualification Date "); and

(ii) 4:59 p.m. (Toronto time) on the date which is four months and a day following the Closing Date (as defined herein).

In the event the Qualification Date has not occurred on or before the date that is 50 days following the Closing Date, each Special Warrant shall thereafter entitle the holder to receive, upon the exercise or deemed exercise of each Special Warrant, for no additional consideration, 1.1 Ordinary Shares. The Canadian Offering is scheduled to close on or about March 9, 2021 (the " Closing Date ") and is subject to certain conditions including, but not limited to, the receipt of all necessary approvals including the approval of the Toronto Stock Exchange.  It is expected that admission of the 76,574,000 Ordinary Shares to trading on AIM upon automatic conversion of the Special Warrants will occur four business days after the earlier to occur of: (i) the issuance of the Prospectus Receipt; and (ii) four months and a day following the Closing Date.

The Canadian Offering is not conditional upon the Placing. The obligation for Paradigm to purchase, or arrange for substituted purchasers for, the Special Warrants is subject to customary conditions and termination provisions including entering into a Underwriting Agreement in customary form, "material adverse change out", "disaster out", "regulatory out" and "breach of agreement out" clauses. The Company has made certain representations, warranties and covenants in the Bought Deal Letter relating to the Company. In the event of a material breach of any of the representations, warranties and covenants included in the Bought Deal Letter, Paradigm will have the right to terminate the Bought Deal Letter. As part of the Canadian Offering, the Directors and executive officers have agreed not to sell any Ordinary Shares held by them for a period of four months and one day, without the consent of Paradigm.

The Ordinary Shares issued upon conversion of the Special Warrants will, when issued, be credited as fully paid and will rank pari passu in all respects with the existing issued Ordinary Shares in the capital of the Company from their date of issue, including the right to receive all dividends and other distributions (if any) declared, made or paid on or in respect of the Ordinary Shares, including the Placing Shares, after the date of issue of those Ordinary Shares.

Settlement and dealings

Settlement for the Placing Shares is expected to take place on or before 8.00am on 23 February 2021.

The Placing is conditional upon, among other things, admission of the Placing Shares becoming effective and the Placing Agreement (as defined in the Appendix to this Announcement) between the Company and the Joint Bookrunners not being terminated in accordance with its terms.

The Appendix to this Announcement sets out further information relating to the terms and conditions of the Placing.

Settlement of the Ordinary Shares issued on conversion of the Special Warrants will occur pursuant to the terms described above under the heading "The Canadian Offering". An application will be made for admission of those shares to trading on AIM and to the TSX in due course. Further announcements regarding the subscription of the Special Warrants, publication of the Canadian short form Prospectus and admission of those shares will be made in due course as required by market rules.

Details of the Placing Agreement and the Placing Shares

The Joint Bookrunners are acting as placement agents in connection with the Placing. The Joint Bookrunners have entered into a placing agreement (the " Placing Agreement ") with the Company under which, on the terms and subject to the conditions set out in the Placing Agreement, the Joint Bookrunners, as agents for and on behalf of the Company, have severally (and not jointly or jointly and severally) agreed to use their respective reasonable endeavours to procure Placees for the Placing Shares at a price of 7.5 pence per Placing Share (the " Placing Price "). The number of Placing Shares in the Placing will be determined following completion of the Bookbuild and set out in a term sheet to be entered into between Joint Bookrunners and the Company (the " Term Sheet "). The final number of Placing Shares will be decided at the close of the Bookbuild. The timing of the closing of the book and allocations will be at the discretion of the Joint Bookrunners. Details of the number of Placing Shares will be announced as soon as practicable after the close of the Bookbuild.

In accordance with the terms and subject to the conditions in the Placing Agreement, the Placing is not underwritten and in the event that subscribers are not obtained for all or any of the Placing Shares (being the " Unplaced Shares ") or in the event of a default to make payment by any subscribers procured by the Joint Bookrunners, there will be no obligation on any Joint Bookrunner to subscribe for any Unplaced Shares or defaulted Placing Shares.

The Placing Shares will, when issued, be subject to the articles of association of the Company and credited as fully paid and will rank pari passu in all respects with the existing issued ordinary shares of £0.01 (" Ordinary Shares ") in the capital of the Company, including the right to receive all dividends and other distributions declared, made or paid in respect of such Ordinary Shares after the date of issue of the Placing Shares.

The Placing is not conditional upon completion of the Canadian Offering (described further below) or the issue of Ordinary Shares upon conversion of the Special Warrants.

Details of the Bought Deal Letter and the Canadian Offering

The Company has entered into the Bought Deal Letter pursuant to which Paradigm has conditionally agreed to purchase 76,574,000 Special Warrants at the Placing Price (the " Canadian Offering "). The Company has granted Paradigm an option to increase the size of the Canadian Offering by up to 11,486,100 Special Warrants at the Placing Price. Each Special Warrant will automatically convert into one Ordinary Share following the Prospectus Receipt by the Company. It is expected that admission of the Ordinary Shares upon automatic conversion of the Special Warrants will be admitted to trading on AIM and listing on the TSX which will occur four business days after the earlier to occur of: (i) receipt of the Prospectus Receipt and; (ii) the date that is four months and a day following the Closing Date. The Company has undertaken to use all commercially reasonable efforts to publish the Canadian Prospectus as soon as possible following AIM Admission and to take all actions reasonably required in order to give effect to the Bought Deal Letter and to procure satisfaction of the conditions contained therein.

The new Ordinary Shares to be issued upon conversion of the Special Warrants will, when issued, be credited as fully paid and will rank pari passu in all respects with the existing issued Ordinary Shares in the capital of the Company from their date of issue, including the right to receive all dividends and other distributions (if any) declared, made or paid or in respect of the Ordinary Shares, after the date of issue of those Ordinary Shares.

The Canadian Offering is being entered into by Paradigm as principal and is underwritten by Paradigm. The Canadian Offering is not conditional upon the Placing. The obligation for Paradigm to subscribe for the Special Warrants is subject to customary conditions including the execution of an Underwriting Agreement in customary form, the publication of the Canadian Prospectus and, amongst other things, "material adverse change out", "disaster out", "regulatory out" and "breach of agreement out" provisions. The Company has given certain warranties and undertakings in the Bought Deal Letter relating to the Company and its operations. In the event of a material breach of any of the undertakings included in the Bought Deal Letter, Paradigm will have the right to terminate.

Settlement of the Ordinary Shares issued on conversion of the Special Warrants in connection with the Canadian Offering will occur as described above following the earlier to occur of: (i) receipt of the Prospectus Receipt and; (ii) the date that is four months and a day following the Closing Date and an application will be made for admission of those shares to trading on AIM and to the TSX in due course. Further announcements regarding publication of the Canadian Prospectus, conversion of the Special Warrants and admission of the new Ordinary Shares issued following such conversion will be made in due course as required by Market Rules.

Applications for admission to listing and trading

Application has been made to the London Stock Exchange for admission of the Placing Shares to trading on AIM. Application will be made to the Toronto Stock Exchange for the Placing Shares to be admitted to trading on the TSX.

It is expected that AIM Admission will take place on or before 8.00 a.m. (London time) on 23 February 2021 and that dealings in the Placing Shares on AIM will commence at the same time.

It is expected that TSX Admission will take place on or before 5.00 p.m. (Toronto time) on 23 February 2021 and that dealings in the Placing Shares on the TSX will commence at the same time.

(b)  allocate Placing Shares after the Bookbuild has closed to any person submitting a bid after that time.

10  Except as required by law or regulation, no press release or other announcement will be made by the Joint Bookrunners or the Company using the name of any Placee (or its agent), in its capacity as Placee (or agent), other than with such Placee's prior written consent.

In particular, none of the Joint Bookrunners nor any of their respective affiliates nor any of its or their agents, directors, officers or employees shall have any liability (including, to the extent permissible by law, any fiduciary duties) in respect of the Joint Bookrunners' conduct of the Bookbuild or of such alternative method of effecting the Placing as the Joint Bookrunners and the Company may agree.

Registration and settlement

If Placees are allocated any Placing Shares in the Placing they will be sent a contract note or electronic confirmation which will confirm the number of Placing Shares allocated to them.

Each Placee will be deemed to agree that it will do all things necessary to ensure that delivery and payment is completed as directed by the relevant Joint Bookrunner in accordance with either the standing CREST or certificated settlement instructions which they have in place with the relevant Joint Bookrunner.

Settlement of transactions in the Placing Shares placed by the Joint Bookrunners following Admission will take place within the system administered by Euroclear UK & Ireland Limited (" CREST "), subject to certain exceptions. Settlement of the Placing Shares through CREST will be on a T+2 basis unless otherwise notified by any Joint Bookrunner and is expected to occur on 23 February 2021 in accordance with the contract notes.

Settlement will be on a delivery versus payment basis. However, in the event of any difficulties or delays in the admission of the Placing Shares to CREST or the use of CREST in relation to the Placing, the Company and the Joint Bookrunners may agree that the Placing Shares should be issued in certificated form. Each of the Joint Bookrunners reserves the right to require settlement for the Placing Shares, and to deliver the Placing Shares to Placees, by such other means as they deem necessary if delivery or settlement to Placees is not practicable within the CREST system or would not be consistent with regulatory requirements in a Placee's jurisdiction.

General

Interest is chargeable daily on payments not received from Placees on the due date in accordance with the arrangements set out above at the rate of two percentage points above LIBOR as determined by the Joint Bookrunners.

Each Placee is deemed to agree that if it does not comply with these obligations, the Joint Bookrunners (or any of them) may sell any or all of their Placing Shares on their behalf and retain from the proceeds, for the Company's own account and benefit, an amount equal to the aggregate amount owed by the Placee plus any interest due. The relevant Placee will, however, remain liable for any shortfall below the Placing Price and for any stamp duty or stamp duty reserve tax (together with any interest or penalties) which may arise upon the sale of its Placing Shares on its behalf.

If Placing Shares are to be delivered to a custodian or settlement agent, Placees must ensure that, upon receipt, the conditional contract note is copied and delivered immediately to the relevant person within that organisation. Insofar as Placing Shares are registered in a Placee's name or that of its nominee or in the name of any person for whom a Placee is contracting as agent or that of a nominee for such person, such Placing Shares should, subject as provided below, be so registered free from any liability to United Kingdom stamp duty or stamp duty reserve tax. Placees will not be entitled to receive any fee or commission in connection with the Placing.

Accordingly, neither the Company nor any of the Joint Bookrunners can provide any advice to US investors as to whether the Company is or is not a PFIC for the current tax year, or whether it will be in future tax years. Accordingly, neither the Company nor any of the Joint Bookrunners undertakes to provide to US investors or shareholders any information necessary or desirable to facilitate their filing of annual information returns, and US investors and shareholders should not assume that this information will be made available to them;

22  its allocation (if any) of Placing Shares will represent a maximum number of Placing Shares which it will be entitled, and required, to subscribe for, and that the Company may call upon it to subscribe for a lower number of Placing Shares (if any), but in no event in aggregate more than the aforementioned maximum;

The agreement to allot and issue Placing Shares to Placees (or the persons for whom Placees are contracting as agent) free of stamp duty and stamp duty reserve tax in the United Kingdom relates only to their allotment and issue to Placees, or such persons as they nominate as their agents, direct by the Company. Such agreement assumes that the Placing Shares are not being acquired in connection with arrangements to issue depositary receipts or to transfer the Placing Shares into a clearance service. If there are any such arrangements, or the settlement related to any other dealings in the Placing Shares, stamp duty or stamp duty reserve tax may be payable. In that event, the Placee agrees that it shall be responsible for such stamp duty or stamp duty reserve tax and neither the Company nor the Joint Bookrunners shall be responsible for such stamp duty or stamp duty reserve tax. If this is the case, each Placee should seek its own advice and they should notify the Joint Bookrunners accordingly. In addition, Placees should note that they will be liable for any capital duty, stamp duty and all other stamp, issue, securities, transfer, registration, documentary or other duties or taxes (including any interest, fines or penalties relating thereto) payable outside the United Kingdom by them or any other person on the acquisition by them of any Placing Shares or the agreement by them to acquire any Placing Shares and each Placee, or the Placee's nominee, in respect of whom (or in respect of the person for whom it is participating in the Placing as an agent or nominee) the allocation, allotment, issue or delivery of Placing Shares has given rise to such non-United Kingdom stamp, registration, documentary, transfer or similar taxes or duties undertakes to pay such taxes and duties, including any interest and penalties (if applicable), forthwith and to indemnify on an after-tax basis and to hold harmless the Company and the Joint Bookrunners in the event that any of the Company and/or the Joint Bookrunners have incurred any such liability to such taxes or duties.

The representations, warranties, acknowledgements and undertakings contained in this Appendix are given to each Joint Bookrunner for itself and on behalf of the Company and are irrevocable.

Each Placee and any person acting on behalf of the Placee acknowledges that the Joint Bookrunners do not owe any fiduciary or other duties to any Placee in respect of any representations, warranties, undertakings, acknowledgements, agreements or indemnities in the Placing Agreement.

Each Placee and any person acting on behalf of the Placee acknowledges and agrees that each Joint Bookrunner may (at its absolute discretion) satisfy its obligations to procure Placees by itself agreeing to become a Placee in respect of some or all of the Placing Shares or by nominating any connected or associated person to do so.

When a Placee or any person acting on behalf of the Placee is dealing with the Joint Bookrunners, any money held in an account with the relevant Joint Bookrunner on behalf of the Placee and/or any person acting on behalf of the Placee will not be treated as client money within the meaning of the relevant rules and regulations of the FCA made under the FSMA. Each Placee acknowledges that the money will not be subject to the protections conferred by the client money rules: as a consequence this money will not be segregated from the relevant Joint Bookrunner's money in accordance with the client money rules and will be held by it under a banking relationship and not as trustee.
