BASIS OF ACCOUNTING AND PRESENTATION
Restricted Cash	Restricted Cash The Company periodically maintains cash deposits that are held and earmarked for a specific purpose. At March 31, 2024, the Company had $188 in restricted cash for amounts held by a third party as security for a surety bond for our Demonstration Plant.
Loss per Share	Loss per Share The loss per share is computed using the weighted average number of shares outstanding during the period. In March 2024, the Company completed the 2024 Rights Offering (Note 7) whereby the Company offered existing shareholders the right to purchase additional common shares at $0.12 per share (the “Offer Price”). The Offer Price was significantly lower than the market trading price of the common shares at that time. The discounted Offer Price is considered a bonus element that is similar to a stock dividend. As a result, the earnings per share calculation is adjusted retroactively for the bonus element for all periods presented. For the three months ended March 31, 2024 and 2023, the Company’s basic earnings per share calculations have been adjusted to include the impact of the bonus element.

Restrictions may include legally restricted deposits held as compensating balances against short-term borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits; however, time deposits and short-term certificates of deposit are not generally included in legally restricted deposits.
