Quaterra Announces Option Agreements to Acquire Butte Valley Porphyry Copper-Gold Prospect, Nevada

Vancouver, British Columbia--(Newsfile Corp. - December 10, 2019) - Quaterra Resources Inc. (TSXV: QTA) (OTCQB: QTRRF) today announced that its wholly-owned subsidiary, Six Mile Mining Company, has signed two option agreements providing it with the right to purchase a 100% interest in 678 unpatented mining claims associated with the Butte Valley prospect, a large, partially explored porphyry copper-gold system located in eastern Nevada about 40 miles north of Ely in north-central White Pine County.

"With these agreements we have the opportunity to acquire a strategic land position over the Butte Valley copper-gold target on very reasonable terms and with no onerous long term financial obligations," says Quaterra President and CEO Gerald Prosalendis. "Butte Valley fits our acquisition profile. It hosts a large porphyry copper-gold system in a mining-friendly state with well-developed infrastructure and where it is feasible to permit, develop and build a mine. It can also be moved to a drill-ready stage relatively quickly because of previous exploration work."

Quaterra is looking for a partner with which to explore the Butte Valley system, including a program of data compilation and geophysics to define targets for several deep drill holes, both within and adjacent to the area of historic exploration. Butte Valley was discovered in the 1960s through the drilling of a large magnetic anomaly. The sulfide system, which covers an area of at least two square miles, is totally blind and is buried below approximately 2,000 feet of gravels and a gravity slide block. Seventeen widely spaced holes have been drilled in the project, the last in 1980. Multiple targets exist, with the property prospective for both high-grade skarn and chalcocite-enriched porphyry copper-gold mineralization.

Today's announcement includes Quaterra subsidiary, Six Mile Mining, signing a lease agreement with North Exploration, LLC, a Nevada prospecting syndicate, giving it the option to purchase 600 unpatented claims covering most of known mineralization at Butte Valley. Under the terms of the agreement, Quaterra paid $5,000 to lease the property until August 2020. Thereafter Quaterra will pay $45,000 in August 2020; $50,000 in August 2021; $100,000 in August 2022; $200,000 in August 2023; and $200,000 in August 2024. Quaterra has the option to purchase the property at any time for $600,000, less previous amounts paid. North Exploration will retain a 2.5% Net Smelter Returns ("NSR") royalty, which Quaterra can reduce to 1.5% by paying $1 million. It can be further reduced to 1% within the first 10 years by Quaterra paying $5 million. (All amounts are in U.S. dollars). Quaterra has the right to explore and develop the property under a budget that it will determine at its sole discretion. It also has the right to terminate the lease agreement at anytime. Quaterra will be responsible for land payments associated with the property.

Six Mile Mining has also signed an option agreement with Nevada Select Royalty, Inc., a wholly-owned subsidiary of Ely Gold Royalties Inc., to purchase a 100% interest in 78 unpatented claims associated with the Butte Valley copper-gold system. Quaterra will make the following payments to Nevada Select during the five-year option period: $15,000 on the effective date; $35,000 on the first anniversary of the agreement; and four payments of $50,000 each on the subsequent four anniversaries of the agreement. Quaterra will also reimburse Nevada Select for staking costs and pay the claim fees during the option period. Upon exercise of the option to purchase, Nevada Select will be granted a 2% NSR. Quaterra will have the right for ten years to reduce the NSR to 1% by paying $10 million. Quaterra has the right to terminate the lease agreement at its discretion.
