Northern Dynasty Welcomes US Government Action to Address Critical Mineral Supply Chain Vulnerabilities

Northern Dynasty Minerals Ltd. (TSX:NDM)(NYSE American:NAK) ("Northern Dynasty" or the "Company") acknowledged today the first tangible step the US government has taken to address the threat to America's economy and military security posed by a severe over-reliance on foreign adversaries for the supply of critical mineral and metals

On October 5, 2020, the United States government announced it would direct the $60 billion US International Development Finance Corporation, a federally-funded lender and investor created under President Trump, to invest $25 million in a UK-based mining group that specializes in producing rare earth metals. The investment in TechMet Ltd. will go toward developing a mine in Brazil that produces nickel and cobalt, both essential for the manufacture of electric vehicles, mobile phones and batteries.

The announcement follows an Executive Order issued by President Trump last week on ‘Addressing the Threat to the Domestic Supply Chain from Reliance on Critical Minerals from Foreign Adversaries." In it, he declares a national emergency and states "our Nation's undue reliance on critical minerals, in processed or unprocessed form, from foreign adversaries constitutes an unusual and extraordinary threat."

The Trump Administration has recognized the threat to America's economic and military security, its domestic manufacturers and other industries, and its ability to respond to climate change through the development of clean and renewable power, since Executive Order 13817 (‘A Federal Strategy To Ensure Secure and Reliable Supplies of Critical Minerals') was issued in 2017. However, the Tech-Met investment represents the first tangible action to address this threat.

The US government previously acknowledged there are 35 minerals "essential to the economic and national security of the United States" that have supply chains vulnerable to disruption, including rhenium. For 31 of these minerals, the country is reliant on foreign producers for between 50 - 100% of its annual needs.

The most recent Executive Order goes further, authorizing use of the Defense Production Act to speed the development of mines in the US, and opening the door to government grants and loans to facilitate domestic mineral production. It also suggests the US could impose tariffs and quotas on mineral imports from China.

While Northern Dynasty does not expect any US government financial support or regulatory assistance with respect to the advancement of its 100%-owned Pebble copper-gold-molybdenum-silver-rhenium project in Alaska, President & CEO Ron Thiessen said recent pronouncements from the Trump Administration underline the importance of developing domestic sources of strategic metals. He said the Pebble Project can help address many of the critical mineral supply vulnerabilities outlined in the President's recent order.

Last week, Northern Dynasty filed its ‘2020 Technical Report on the Pebble Project, Southwest Alaska, USA,' highlighting a revised mineral resource estimate that establishes Pebble as the most significant source of rhenium in the world (see https://www.northerndynastyminerals.com/site/assets/files/4870/2020-10-02-ndm-nr.pdf).

Rhenium is one of 35 critical minerals acknowledged by the US government, and one for which the country is reliant on foreign producers for 82% of its needs (see https://doi.org/10.3133/mcs2020). Jet engine and related military applications account for 80% of annual US rhenium consumption, in addition to industrial applications that employ rhenium as a catalyst - including for the production of high-octane, lead-free gasoline.

Once in production, the proposed Pebble mine has the potential to produce ~12,000 kg of rhenium each year over 20 years of operations[1]. This represents a 143% increase in the United States' annual production of rhenium over 2019 levels. This level of production could also reduce the percentage of US rhenium requirements sourced from offshore producers by 25% over 2019 levels.

Last week's Executive Order also provides impetus to the domestic production of other metals present in the Pebble deposit, and for which the United States is currently dependent on countries with inferior records for health and safety, human rights and environmental protection. In addition to rhenium, the US currently relies on foreign producers for 35% of its annual copper needs and 68% of its annual silver needs.

"We are excited to be advancing Pebble through federal permitting at a time when the US is focusing its attention on promoting the domestic production of important metals," Thiessen said. "Once in production, Pebble will significantly increase US domestic production of several strategic minerals and metals - including copper, rhenium, molybdenum and silver, among others - while reducing US dependence on foreign suppliers."

From the ‘Executive Order on Addressing the Threat to the Domestic Supply Chain from Reliance on Critical Minerals from Foreign Adversaries':

"In addition, I find that the United States must broadly enhance its mining and processing capacity, including for minerals not identified as critical minerals and not included within the national emergency declared in this order. By expanding and strengthening domestic mining and processing capacity today, we guard against the possibility of supply chain disruptions and future attempts by our adversaries or strategic competitors to harm our economy and military readiness. Moreover, additional domestic capacity will reduce United States and global dependence on minerals produced in countries that do not endorse and pursue appropriate minerals supply chain standards, leading to human rights violations, forced and child labor, violent conflict, and health and environmental damage. Finally, a stronger domestic mining and processing industry fosters a healthier and faster-growing economy for the United States. Mining and mineral processing provide jobs to hundreds of thousands of Americans whose daily work allows our country and the world to "Buy American" for critical technology."
