Arena Minerals Inc. ("Arena" or the "Company") (TSX-V: AN) announces the closing of the second and final tranche of the non-brokered private placement announced on February 4, 2021. The Company has issued an additional 25,236,278 units (the "Units") at a price of $0.05 per Unit for additional proceeds of $1,261,813. Each Unit consists of one common share of the Company (a "Common Share") and one-half of one common share purchase warrant (each whole warrant, a "Warrant"). Each Warrant entitles the holder to acquire one Common Share of the Company at $0.15 for a period of 36 months from the date of issuance. The shares, warrants and any shares issued upon the exercise of the warrants issued in this second tranche closing are subject to a hold period which expires March 16, 2021. With the closing of the first tranche which closed on March 15, the total raised in the financing was $2.8 million.

GFL International Co., Ltd, a wholly owned subsidiary of Ganfeng Lithium Co. ("Ganfeng"; 1772.HK; OTCQX: GNENF), an established global lithium carbonate producer, has acquired a total of 39,525,596 Units for gross proceeds of $1,976,280 pursuant to the terms of the offering.

Arena also announces that 9,205,000 warrants with a strike price of $0.10 have recently been exercised for total proceeds of $920,500. An additional 36,795,000 unexercised warrants with a strike price of $0.10 expire on September 10, 2021. Considering this and the present closing, Ganfeng now owns 19% of the Company's issued and outstanding Common Shares.

Ganfeng is one of the world's leading lithium manufacturers and is listed on the Shenzhen Stock Exchange and on the Hong Kong Stock Exchange since 2018 when it raised US$ 440 million in an IPO. Ganfeng is a top three lithium compound producer, and the largest producer of lithium metal globally. Ganfeng has a strong presence in Argentina, including a 51% ownership in Minera Exar whom operates the Cauchari Lithium project in Jujuy province.

As a result of the non-brokered private placement, the exercise of warrants, previously held cash and cash equivalents, the Company is now well financed for the advancement of its drill ready lithium brine properties in Argentina and other corporate initiatives. The proceeds from the Offering will be used by Arena to develop its Antofalla lithium brine property in the puna region of Argentina, for potential acquisitions, and for general corporate purposes. Arena's Antofalla properties comprise a total of 6,000 hectares covering a portion of the Antofalla salar located in Catamarca, Argentina. The properties are immediately south and adjacent to Albemarle Corporation's similarly named Antofalla project.

Mr. Eduardo Morales, Executive Chairman of Arena, commented: "We are now in a strong position, thanks to our healthy financial situation and our partnership with Ganfeng Lithium, one of the world's largest and most successful companies in the battery materials sector, to execute on our business plan. Alongside developing the Antofalla project, we have a clear strategy in mind to grow this Company to become a lithium producer by targeting and acquiring further mid-size projects to complement Antofalla. As stated before, our objective is to ultimately own and operate several high-quality assets and supply lithium chloride to a centralized chemical plant. We are convinced this is the future of the brine lithium industry, allowing assets to be developed without incurring excessive capital costs while reducing the technical risk of having to build and operate a chemical plant." Mr. Morales is the former President of Rockwood Litio Ltda (Chile), where he oversaw the development of the world's premier lithium brine asset in the Salar the Atacama, Chile. Rockwood was sold in 2014 for USD 6.2 Billion.

Under its subscription agreement with Arena, and provided it holds at least 7.5% of Arena's common shares, Ganfeng has been granted the right (i) to participate in future Arena financings to maintain its percentage ownership interest in Arena; (ii) to acquire up to 35% interest in any asset acquisition completed by Arena; and iii) a Right of First Offer on off-take agreements on a per project basis. Ganfeng has also been granted the right to appoint a nominee to the Arena board of directors as long as it holds at least 10% of Arena's common shares.
