Significant Exploration Agreements

NORI Exploration Contract:

The Company’s wholly-owned subsidiary, NORI, was granted an exploration contract (“NORI Exploration Contract”) on July 22, 2011 under the sponsorship of Nauru. The contract application fee of $0.3 million, provides NORI with exclusive rights to explore for polymetallic nodules in the NORI Area for an initial term of 15 years (renewable for successive five-year periods) subject to complying with the exploration contract terms (Note 22) and provides NORI with the priority right to apply for an exploitation contract to collect polymetallic nodules in the same area. The NORI Exploration Contract terminates on July 22, 2026, and the Company has filed for an extension.

NORI has a right to renounce, without penalty, in whole or part of its rights in the NORI Area at any time and therefore does not have a fixed commitment with relation to the NORI Exploration Contract (Note 22).

TOML Exploration Contract:

TOML was granted an exploration contract (“TOML Exploration Contract”) on January 11, 2012 under the sponsorship of Tonga. The TOML Exploration Contract provides TOML with exclusive rights to explore for polymetallic nodules in the TOML Area for an initial term of 15 years (renewable for successive five-year periods) subject to complying with the exploration contract terms and a priority right to apply for an exploitation contract to collect polymetallic nodules in the same area. The TOML Exploration Contract terminates on January 11, 2027.

On March 31, 2020, the Company entered into an acquisition agreement with Deep Sea Mining Finance Ltd. to acquire TOML and other related entities in the group (the “TOML Acquisition”).
