Lifezone Metals launches off-take marketing process for nickel, copper and cobalt from the Kabanga nickel project

LONDON,April 19,2023 -- Lifezone Holdings Limited ("Lifezone Metals") has previously announced entry into a Business Combination Agreement with GoGreen Investments Corporation (NYSE: GOGN),a publicly traded company on the NYSE ("GoGreen"). Today,Lifezone Metals is pleased to announce that it has commenced an off-take marketing process with respect to the nickel,copper and cobalt from the Kabanga nickel project (the "Kabanga Project"),which Lifezone Metals believes comprises one of the world's largest and highest-grade nickel sulfide deposits.

Lifezone Metals seeks to support the clean energy transition through licensing of its proprietary hydromet mineral processing technology (the "Hydromet Technology") as an alternative to smelting in metals production and becoming an emerging supplier of responsibly-sourced,low-carbon and low-sulfur dioxide emission metals to the battery,electric vehicle ("EV") and hydrogen markets. Lifezone Metals is entitled to certain off-take marketing rights with respect to the Kabanga Project and has retained the marketing rights for up to 40%,in aggregate,of the total contained nickel,cobalt and copper production from the Kabanga Project.

Given the interest in these products from original equipment manufacturers,the company has commenced a process aimed at monetising the off-take from the Kabanga Project. RBC Capital Markets has been engaged to run a formal off-take marketing process. Further updates on the process will be provided as appropriate.

Chris Showalter,CEO of Lifezone Metals,said: "The commencement of the off-take marketing process for the nickel,cobalt and copper to be produced at the Kabanga Project is a key milestone in the development of Lifezone Metals,as we work to build a champion for cleaner metals to support the global energy transition.

There is a clear focus on upstream environmental footprint driven by consumer demand and regulatory targets in the US and Europe,and we expect a shift away from heavy-polluting sources of raw materials into the battery and EV supply chain. Recent test results indicate that the Kabanga Project's nickel concentrate is amenable to processing using the Hydromet Technology,which we believe is key to unlocking the value of the project and paving the way for our future cleaner metal products."

About Lifezone Metals

Lifezone Metals is a modern metals company creating value across the battery metals supply chain from resource to metals production and recycling. Our mission is to provide commercial access to proprietory technology and cleaner metals production through a scalable platform underpinned by our tailored hydromet technology. This technology has the potential to be a cleaner and lower cost alternative to smelting,allowing us to responsibly and cost-effectively provide cleaner metals.

By pairing Tanzania's Kabanga Project,which we believe is one of the largest and highest-grade undeveloped nickel sulphide deposits in the world,with our proprietary hydromet technology,we will work to unlock the value of a key new source of supply to global battery metals markets. We partner with BHP on the Kabanga Project as we aim to empower Tanzania to achieve full value in-country and become the next premier source of nickel.

These risks and uncertainties include,but are not limited to: general economic,political and business conditions,including but not limited to the economic and operational disruptions and other effects of the COVID-19 pandemic; the inability of the parties to consummate the business combination or the occurrence of any event,change or other circumstances that could give rise to the termination of the business combination agreement; the number of redemption requests made by GoGreen's shareholders in connection with the business combination; the outcome of any legal proceedings that may be instituted against the parties following the announcement of the business combination; the risk that the approval of the shareholders of Lifezone Metals or GoGreen for the potential transaction is not obtained; failure to realize the anticipated benefits of the business combination,including as a result of a delay in consummating the potential transaction or difficulty in integrating the businesses of Lifezone Metals and GoGreen; the risk that the business combination disrupts current plans and operations as a result of the announcement and consummation of the business combination; the risks related to the rollout of Lifezone Metals' business,the efficacy of the Hydromet Technology,and the timing of expected business milestones; Lifezone Metals' development of,the Kabanga Project; the effects of competition on Lifezone Metals' business; the ability of the combined company to execute its growth strategy,manage growth profitably and retain its key employees; the ability of Lifezone Metals Limited ("Holdings") to obtain or maintain the listing of its securities on a U.S. national securities exchange following the business combination; costs related to the business combination; and other risks that will be detailed from time to time in filings with the U.S. Securities and Exchange Commission (the "SEC").

In addition,forward-looking statements provide Lifezone Metals' expectations,plans or forecasts of future events and views as of the date of this communication. Lifezone Metals anticipates that subsequent events and developments will cause Lifezone Metals' assessments to change. However,while Lifezone Metals may elect to update these forward-looking statements in the future,Lifezone Metals specifically disclaims any obligation to do so. These forward-looking statements should not be relied upon as representing Lifezone Metals' assessments as of any date subsequent to the date of this communication. Accordingly,undue reliance should not be placed upon the forward-looking statements. Nothing herein should be regarded as a representation by any person that the forward-looking statements set forth herein will be achieved or results of such forward-looking statements will be achieved.

Certain statements made herein include references to "clean" or "green" metals,methods of production of such metals,energy or the future in general. Such references relate to environmental benefits such as lower green-house gas ("GHG") emissions and energy consumption involved in the production of metals using the Hydromet Technology relative to the use of traditional methods of production and the use of metals such as nickel in the batteries used in electric vehicles. While studies by third parties (commissioned by Lifezone Metals) have shown that the Hydromet Technology,under certain conditions,results in lower GHG emissions and lower consumption of electricity compared to smelting with respect to refining platinum group metals,no active refinery currently licenses Lifezone Metals' Hydromet Technology. Accordingly,Lifezone Metals' Hydromet Technology and the resultant metals may not achieve the environmental benefits to the extent Lifezone Metals expects or at all. Any overstatement of the environmental benefits in this regard may have adverse implications for Lifezone Metals and its stakeholders.
