ELEMENT ONE HYDROGEN and CRITICAL MINERALS ARRANGES FINANCINGS AND INITIATES MARKETING CAMPAIGN

Element One Hydrogen and Critical Minerals Corp. has closed two non-brokered private placements for total gross proceeds of $544,950. The company has allocated and issued a first tranche of 2,633,000 units at a price of 15 cents per unit. Each unit consists of one of the company and one transferable share purchase warrant, with each unit warrant entitling the holder to acquire one additional common share at an exercise price of 20 cents for a period of 36 months from the closing date. The units have been purchased by directors and officers of the company.

The company has allocated and issued 3.0 million transferable share purchase warrants at a price of five cents per warrant, with each warrant entitling the holder to acquire one common share of the company at an exercise price of 25 cents for a period of 12 months from the closing date.

All securities issued under these private placements will be subject to a hold period of four months plus one day. There were no finders' fees involved with the offerings.

The gross proceeds from both private placements will be used for continuing research, marketing, and general and administrative expenses.

Two insiders of the company subscribed in the units for aggregate gross proceeds of $394,950. The issuance of units to the insiders are considered a related party transaction within the meaning of Multilateral Instrument 61-101, Protection of Minority Security Holders in Special Transactions. The company relied on exemptions from the formal valuation and minority shareholder approval requirements provided under sections 5.5(a) and 5.7(a) of MI 61-101 on the basis that the insiders participation in the private placement did not exceed 25 per cent of the fair market value of the company's market capitalization. The company will file a material change report in respect of the related party transaction.
