(TSXV: BTR) (OTCQX: BONXF) (FSE: 9BR2) ("Bonterra" or the "Company") is pleased to announce that it has closed the second and final tranche of the non-brokered private placement previously announced on November 23, 2020, December 3, 2020 and first tranche closing on December 9, 2020 (the "Offering"). In the final tranche, the Company raised aggregate gross proceeds of $2,729,625 (the "Final Tranche") from the sale of 2,373,587 common shares of the Company (the "Shares") at a price of $1.15 per Share. The total number of Shares sold in the Offering was 13,043,478 for aggregate gross proceeds for all tranches of $15 million.

This news release contains "forward-looking information" that is based on Bonterra's current expectations, estimates, forecasts and projections. This forward-looking information includes, among other things, statements with respect to Bonterra's exploration and development plans, the execution of its strategy, the terms and timing of the proposed financing, and potential strategic alternatives and transactions that the Company may pursue. There can be no assurance that the Company will complete its proposed financing. Any financing may be subject to applicable regulatory approvals, including of the TSX Venture Exchange. In addition, the PEA may not be completed as planned or at all and the results of such PEA are unknown at this time and may indicate that the projects may have economic values below the Company's expectations.

This forward-looking information includes namely, information with respect to the planned exploration programs and the potential growth in mineral resources. Exploration results that include drill results on wide spacings may not be indicative of the occurrence of a mineral deposit and such results do not provide assurance that further work will establish sufficient grade, continuity, metallurgical characteristics and economic potential to be classed as a category of mineral resource. The potential quantities and grades of drilling targets are conceptual in nature and, there has been insufficient exploration to define a mineral resource, and it is uncertain if further exploration will result in the targets being delineated as mineral resources. Forward-looking information is subject to known and unknown risks, uncertainties and other factors that may cause Bonterra's actual results, level of activity, performance or achievements to be materially different from those expressed or implied by such forward-looking information. Such factors include but are not limited to: uncertainties related exploration and development; the ability to raise sufficient capital to fund exploration and development; changes in economic conditions or financial markets, environmental and other judicial, regulatory, political and competitive developments; technological or operational difficulties or inability to obtain permits encountered in connection with exploration activities; and labour relations matters.
