TORONTO, March 01, 2021 - Arena Minerals Inc. ("Arena" or the "Company") (TSX-V: AN) announces that it has closed an initial tranche of its private placement announced on February 4, 2021. The Company has issued an aggregate of 30,763,720 units (the "Units") at a price of $0.05 per Unit for gross proceeds of $1,538,186. 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.

Ganfeng Lithium Co. ("Ganfeng"; 1772.HK; OTCQX: GNENF) acquired 17,489,321 Units in the first tranche closing, and now holds approximately 9.9% of the Company's issued and outstanding shares. Ganfeng will acquire an additional 22,036,279 Units in a second closing which is expected to take place in approximately two to three weeks. Following completion of the second closing, Ganfeng will have acquired 39,525,600 Units. Ganfeng has undertaken not to exercise any Warrants which would result in it holding 10% or more of the Common Shares until the TSXV has confirmed it has completed a routine personal information form review required in the case of new insiders, and has further undertaken not to exercise any Warrants which would result in it holding 20% or more of the Common Shares until receipt of shareholder approval for it becoming a control person of the Company, as such term is defined in the TSXV Corporate Finance Manual.

The Common Shares and Warrants issued in the first tranche closing and any shares issued upon the exercise of the Warrants are subject to a four month resale hold period which expires on June 26, 2021.

The proceeds from the placement 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.
