NEW YORK,July 6,2023 --Lifezone Metals Limited ("Lifezone Metals" or the "Company") (NYSE: LZM),a modern metals company creating value across the battery metals supply chain from resource to metals production and recycling,is pleased to announce that on July 6,2023,Lifezone Holdings Limited ("LHL") completed the previously announced business combination (the "Business Combination") with GoGreen Investments Corporation ("GoGreen"),formerly a blank check company listed on the New York Stock Exchange ("NYSE"). Lifezone Metals' ordinary shares and warrants are expected to begin trading on the NYSE under the ticker symbols "LZM" and "LZMW",at the opening of trading today.

The Business Combination was implemented through a newly created holding company,Lifezone Metals. Upon completion of the Business Combination,GoGreen merged into a wholly-owned subsidiary of Lifezone Metals,after which GoGreen ceased to exist and the shareholders of GoGreen received shares in Lifezone Metals,and LHL was acquired by Lifezone Metals,after which LHL became an operating wholly-owned subsidiary of Lifezone Metals and the shareholders of LHL received shares in Lifezone Metals. The completion of the Business Combination establishes the first pure-play nickel resource and cleaner technology company listed on the NYSE.

The Company received gross proceeds from the transaction of approximately $86.6 million,including approximately $70.2 million in aggregate from a private investment in public equity ("PIPE") and the receipt of approximately $16.4 million of cash from GoGreen's trust account,net of redemptions. These proceeds are in addition to the previously announced investments by BHP Billiton (UK) DDS Limited ("BHP") of $90 million into Kabanga Nickel Limited ("KNL"),the owner of the Kabanga project in North-West Tanzania (the "Kabanga Project"),and of $10 million into Lifezone Limited,both which are subsidiaries of the Company.

Keith Liddell,Chairman of Lifezone Metals,said: "Today is a momentous occasion in the corporate evolution of Lifezone Metals and one we are immensely proud of. For nearly 30 years,Lifezone Metals' CTO Dr. Mike Adams and I have been developing and improving our Hydromet Technology as a cleaner,lower cost,and more efficient alternative to smelting in the metals extraction process."

Chris Showalter,Chief Executive Officer of Lifezone Metals,continued:"With the electrification of transportation inflecting and the demands to decarbonize our economies broadly intensifying,we believe Lifezone Metals stands to be a critical enabler of ensuring that in the process of attempting to create a greener tomorrow through the replacement of internal combustion engine vehicles with electric vehicles (EVs),the automotive industry isn't offsetting these gains through a significant ramp-up in the toxic emissions derived from smelting in the EV battery supply chain.

We are excited to take on our mission to build long-term value for our shareholders in the public markets by delivering on our milestones as we plan to bring our bellwether Kabanga Project to commercialization,and as we plan to deploy our Hydromet Technology to unlock the value of other stranded assets and decarbonize the secondary supply chain."

John Dowd,CEO of GoGreen,said: "On behalf of the entire GoGreen team,we congratulate Lifezone Metals on achieving this tremendous milestone. We believe Lifezone Metals' unique winning value proposition is underpinned by an unfolding generational push towards decarbonization – and we believe this foundation is strengthened on its new public platform.

We believe the company's Hydromet Technology is a game changer in unlocking value from stranded assets in a cleaner and more responsible way. The Company's high-quality,low-cost nickel sulphide Kabanga Project in Tanzania will showcase the value of this technology,and positions the Company well to be an early provider of critical cleaner metals for automotive OEMs as they progress along their electrification journeys."

Lifezone Metals Overview

With growth in EVs accelerating,meeting the demands of metals required for EV batteries will require significant growth in the metals supply chain and especially nickel,which is estimated to represent up to 80%[1]of active lithium-ion battery materials. At the same,automakers are increasingly focused on decarbonizing the supply chain,driven by consumer demand and regulatory targets,which includes the upstream environmental footprint of battery materials.

Lifezone Metals' flagshipKabanga Project in North-West Tanzania is estimated to be one of the largest and highest quality undeveloped nickel sulphide deposits in the world,and industry estimates suggest that it sits in the first quartile of both the cost and carbon curves[2]. These favourable characteristics are enabled by the Company's proprietary Hydromet processing technology,which is a lower-energy intensity,significantly less carbon intensive,and lower cost alternative to smelting. Smelting,the traditional method of metals extraction,is estimated to contribute up to 7% of global greenhouse gas emissions[3]. For the Kabanga Project,the Hydromet Technology is estimated to reduce carbon dioxide emissions by up to 73%[4][5]compared to traditional smelting and is free of sulfur dioxide. More broadly,the Company's Hydromet Technology can potentially reduce capital and operating costs by up to 79% and 41%,respectively[6]. We believe Lifezone Metals' use of its Hydromet Technology,including via licensing,will be valuable well beyond the Kabanga Project,including for the development of other critical metals deposits and as a cleaner alternative to smelting for the metals recycling industry.

Kabanga Project Overview

The Kabanga Project is an exploration-stageproject. According to the mineral resource estimate[7]the Company has an attributable tonnage portion of approximately 44 million tons at an average in-situ nickel grade of 2.61%,plus 0.35% copper and 0.19% cobalt. Once operational,it is contemplated that the Kabanga mine and its proposed associated hydromet refinery at Kahama will produce refined high-grade nickel,LME Grade A copper cathode,and cobalt. In January 2021,Lifezone Metals' subsidiary,KNL,entered into a framework agreement with the Government of Tanzania setting out,among other things,the arrangement in relation to the conduct of future mining operations for the Kabanga Project. In April 2021,KNL acquired the intellectual property rights and the existing assets to the Kabanga Project,and in October 2021,the Government of Tanzania issued a special mining license ("SML") to KNL's subsidiary.The various previous owners of the Kabanga Project cumulatively conducted drilling of 587 kilometers through 1,404 drillholes and cumulatively spent approximately $293million on drilling and studies. The Company believes this provides adeep understanding of the potential value of the asset that the Hydromet Technology can unlock in a potentially more economic and environmentally friendly way.

With the support of global leading resources company,BHP,including its aggregate investments of $100 million,Lifezone Metals believes it is well on its way to unlocking the world class Kabanga asset. The Company is at present making good progress on early site works,environmental planning,further SML exploration and feasibility studies towards its goal of achieving first ore in 2026.

[5]Expected reductions are lower for platinum group metals ("PGMs"),as they utilize a more complicated flowsheet and are more energy intensive. For example,a study from EY Cova (an independent South African National Accreditation System accredited energy Measurement and Verification inspection body) found 46% lower emissions utilizing Lifezone Metals' hydromet technology compared to traditional smelting and refining (EY Cova studied PGM metals at the originally proposed 110 ktpa concentrate feed rate refinery at the Sedibelo plant site in South Africa under the then-applicable conditions in 2020 and assuming reagents not manufactured on-site; actual results could differ). Results will vary for specific PGM projects.
