Gerard Barron, CEO and Chairman of The Metals Company commented: “Today’s certification of our USA B exploration license application marks another important milestone in NOAA’s transparent, rules-based process and we look forward to the development and publication of an EIS. Exploration is a critical step to unlocking the transformative potential of the untapped nodule resource for the United States.” Certification represents a key step in a steady cadence of expected regulatory milestones: <ul type="disc"><li>NOAA is expected to soon publish a Notice of Intent to Prepare an Environmental Impact Statement, followed by the development and then publication for public comment of a draft EIS and draft Terms, Conditions and Restrictions (TCRs) for TMC USA’s proposed exploration activities on the USA B area</li><li>Following the public comment period, the EIS will be finalized and NOAA will make a final determination on the issuance of the license and its associated TCRs</li></ul> The Company and its partners have conducted over a decade of <a href="https://www.globenewswire.com/Tracker?data=9Zileg7bUw4xR9ganqH85l8caOpJqEZbNsEzFknpV5ZHpf82m44T4Ni1iAv9U48YKMkpiaGRw7l8jU-i4MQsxDLTW5yfvv4jAZAWop5clUUF629tnmqXKRpt4OO-_sGTztXh5lE9J5aX_KS6mlJEKY-WaEpEvi5I8SCnS6XTB-rAj2Ziftn4H87Pdge7WILlSAU_0hp3999xz9SvAZR5a6URW1NdZyynFmQu87JSwjXRNMRYFgQyO5wdBVqWeObd" rel="nofollow" target="_blank" title="scientific research">scientific research</a>, environmental data collection, and <a href="https://www.globenewswire.com/Tracker?data=_XPi2-hOOWQ1Cq3NTwmm8gBTcaOuGhvYYtd1liPHH5K0zjA25bwA13uaB4hWRwABMviAGegtgzAIi-_sqkci3uqRDftvsAmjZfUXsaQtsisxgVRqhjcS8w5ZIX7v0wTYj7O-OxbMiKQPpURBzQ-Tlfche71ulHLa1SaZtTTXvuVeS7x9pL6CAHIVh3_1eCekvc18MnbFFTG2H_lm_8qCik-p3Zc9Zb2-HmQQyWgjGC6sRiWBkbLfinGYDJQNGuKsB5amEYxOROZhR9N9spkIqAlMkIMjK8xQdIwIPXVdcPo=" rel="nofollow" target="_blank" title="offshore engineering">offshore engineering</a>, building one of the most comprehensive datasets ever assembled on polymetallic nodules and their surrounding ecosystems.

The exploratory activities outlined as part of TMC USA’s USA B exploration license application are expected to generate significant new data and, with all academics involved free to publish, the Company anticipates that hundreds more papers will be published over the coming months and years. NOAA has played a central role in advancing scientific understanding of deep seabed mining impacts since the 1970s, including conducting environmental research cruises in the CCZ, monitoring early nodule collection trials, and publishing a Programmatic Environmental Impact Statement covering the CCZ in 1981. The agency issued comprehensive DSHMRA implementing regulations in 1981 (exploration licenses) and 1989 (commercial recovery permits) and has maintained an active licensing program since that time, with multiple exploration licenses renewed on a five-year basis. About The Metals Company The Metals Company is a developer of lower-impact critical metals from seafloor polymetallic nodules, on a dual mission: (1) supply metals for energy, defense, manufacturing and infrastructure with net positive impacts compared to conventional production routes and (2) trace, recover and recycle the metals we supply to help create a metal commons that can be used in perpetuity. The Company has conducted more than a decade of research into the environmental and social impacts of offshore nodule collection and onshore processing.
