Quaterra Resources Announces Closing of Oversubscribed Private Placement and Option to Acquire B.C. Mining Properties

Vancouver, October 21, 2021 - Quaterra Resources Inc. (TSXV: QTA) (OTCQB: QTRRF) the "Company") is pleased to announce that it has completed an oversubscribed third and final tranche of its previously announced non-brokered private placement (the "Private Placement"). Proceeds will be used to advance the Company's assets, primarily its MacArthur copper oxide project in Nevada, and general working capital.

Pursuant to the closing of the third tranche, the Company has issued 29,832,834 units ("Units") at a price of US$0.06 (C$0.075) per Unit for gross proceeds of US$1,789,970 (C$2,237,463). Combined with the first and second tranches, the Company has raised an aggregate of US$4,128,140 (C$5,160,175) in the Private Placement.

Each Unit consists of one common share of the Company and one non-transferable share purchase warrant (a "Warrant"). Each Warrant entitles the holder to acquire one additional common share of the Company at an exercise price of US$0.10 per share for a period of three years from the date of closing. The Warrants contain a forced exercise provision if the daily volume weighted average trading price of the common shares of the Company on the TSX Venture Exchange (the "Exchange") is equal to or greater than US$0.30 for a period of 10 consecutive trading days.

In connection with the completion of the third tranche of the Private Placement, the Company paid a total of US$110,388 and issued an aggregate of 1,839,798 finder's warrants as finder's fees. The finder's warrants are exercisable at a price of US$0.10 per share for a period of 3 years from the date of closing.

The securities issued pursuant to the third tranche of the Private Placement are subject to a four-month hold period expiring on February 22, 2022 in accordance with applicable securities laws.

Letter of Intent to Acquire B.C. Exploration Properties: Chaco Bear and Ashton Properties

The Company further announces that it has entered into a non-binding letter of intent (the "LOI") with Houston Minerals Ltd. and certain affiliated persons pursuant to which the Company was granted the option to acquire a 100% interest in the Chaco Bear Property located directly east of the Golden Triangle of British Columbia, and the Ashton Property located near Lytton, British Columbia (Collectively, the "Properties"), subject to a 2.5% net smelter return royalty (the "NSR") on each property. The Properties are comprised of 19 mineral claims covering 7,975.46 hectares. A map providing the location of the claims for each of the Properties is provided in Figures 1-3 below.

Mr. Travis Naugle, CEO, states that these "B.C. Properties represent an exciting opportunity to create value for our shareholders. The Chaco Bear Property appears to be a compelling analogue to the world-class Eskay Creek gold deposit and we look forward to further exploring this potential. The Ashton Property represents one of the earliest staked properties in the emerging Spences Bridge Gold Belt and we believe it to be a prime exploration opportunity, with multiple drill targets already identified." Mr. Naugle also states that the support of the vendor in completing this LOI, including their participation in Quaterra's financing, was appreciated.

Under the terms of the LOI, the Company can earn up to a 100% interest in the Properties by making the following issuances and payments over a four year period:

• issuing 8,000,000 common shares of the Company on closing
• making annual lease payments on the Properties after 2021
• incurring C$150,000 of exploration expenditures on the Chaco Bear Property and C$50,000 of exploration expenditures on the Ashton Property before the end of 2021
• incurring exploration expenditures of at least the value of the annual assessment multiplied by 1.5 for periods after 2021
• paying C$1,500,000 for the Chaco Bear Property and C$1,000,000 for the Ashton Property on or before 4 years from the closing, which amounts are payable in cash or common shares of the Company
• making annual advance royalty payments in the fourth and fifth year from the closing in the amounts of C$250,000 on the Chaco Bear Property and C$150,000 on the Ashton Property

Prior to feasibility, the Company may reduce the NSR to 1.0% on the Chaco Bear Property in consideration for a payment of C$6,000,000 and 1.0% on the Ashton Property for a payment of C$3,000,000. Post feasibility, the Company may purchase the remaining 1.0% NSR on the Chaco Bear Property for C$12,000,000 and the remaining 1.0% NSR on the Ashton Property for C$6,000,000.

Closing of the transaction contemplated in the LOI is subject to the parties entering into a definitive agreement and stock exchange approval.
