and net cash proceeds of $22,865,049.

The 2019 Debentures bear interest at a rate of 10% per annum, paid quarterly, and mature on May 31, 2022, at which time the outstanding principal amount of $23,457,500 and any unpaid interest is repayable in cash if the 2019 Debentures have not been converted at the option of the holder or otherwise extinguished.

The principal amount of the 2019

Debentures is convertible into 1,563,833

units of the Company at the option of the holder at any time prior to maturity at a conversion price of $15.00

per unit.

At June 30, 2022, no units had been converted.

Each unit is comprised of one common share and one share purchase warrant. Each warrant is exercisable to acquire one common share at an exercise price of $22.50

until June 2024

b)	2021 Convertible debentures

Issuance of Convertible Debentures

On December 7, 2020, the Company commenced efforts to raise an aggregate of US$10,000,000 through a private placement offering (the “Offering”) of convertible unsecured subordinated debentures (the “2021 Debentures”) at a price of US$100 per debenture. At December 31, 2020, total proceeds of $5,285,997 (US$4,146,825) had been received associated with two tranches of the Offering; however, as the debenture certificates were not yet issued the proceeds were recorded as other liabilities in the consolidated statement of financial position at December 31, 2020 (Note 16).

The Offering closed in six tranches between December 7, 2020 and May 25, 2021 with total gross proceeds of $11,328,870 (US$8,884,000). Each tranche had a specific maturity date and USD conversion price which was set at the date of close. The conversion prices ranged between $4.11 (US$3.42) and $8.28 (US$6.60) depending on the tranche.

Up until the date of conversion as described below under

Conversion of Convertible Debentures

, the maturity date of the 2021 Debentures was 36 months following the closing date of the applicable tranche. The principal amounts of the 2021 Debentures were convertible into common shares at the option of the holder at any time prior to maturity at the calculated conversion price stated in the debenture. The 2021 Debentures bore interest at 8% per annum, payable, at the option of the Company, in cash or common shares of the Company calculated in accordance with the debenture agreement which considered such factors as the price of the common stock on the TSX.V converted into USD at the date of record. The Company elected to pay all accrued interest in common shares which were issued on the conversion date.

On initial recognition, the 2021 Debentures included a host liability and embedded derivative conversion option. The fair value of the embedded derivative was determined first, with the residual amount of the total fair value of the convertible debentures allocated to the host liability. The host liability was classified as a financial liability recognized at amortized cost and the embedded derivative conversion option was an embedded derivative classified as fair value through profit or loss (“FVTPL”). The fair value measurement is further described in Note 26(b) - Financial Instruments under

Valuation methodologies used in the measurement of fair value for Level 3 financial liabilities.

Conversion of Convertible Debentures

On July 12, 2021, the Company announced that it had entered into Debt Conversion and Exchange Agreements (“Conversion Agreements”) with holders of more than 99.2% of the outstanding principal amount of the 2021 Debentures subject to a number of conditions including TSX.V approval. The Conversion Agreements provided for certain changes in terms including a reduced conversion price on certain tranches of the 2021 Debentures and the addition of a common share purchase warrant for each common share to be issued upon conversion.

On August 13, 2021, the Company received TSX.V approval and issued an aggregate of 2,107,787 common shares and 2,107,787 common share purchase warrants (Note 19(a)) to extinguish 99.2% of the principal and accrued interest thereon to the date of the Conversion Agreements.

The following reconciliation includes: (a) the original issuance of and accounting for the convertible debentures up to July 12, 2021; (b) the derecognition of the host liability and embedded derivative on July 12, 2021 as the change in terms of the agreement was determined to be a substantial modification and resulted in recognition of a new financial liability at this date; (c) the extinguishment of the amount due under the 2021 Debentures on August 13, 2021 in exchange for common shares and warrants; and (d) the accounting for the remaining debenture which was not converted. The warrants issued continue to be financial liabilities of the Company as further described

Note 15.
