TMC the metals company (TMC) Corporate presentation summary

Resource potential and context

• Seafloor hosts vast reserves of nickel, cobalt, and manganese, surpassing global land reserves for these metals.

• Polymetallic nodules can replace multiple terrestrial mines, offering a concentrated source of critical metals.

• Abyssal plains, where nodules are found, are deep, food-poor, and have low biomass and biodiversity compared to terrestrial and shallower marine environments.

Environmental research and monitoring

• Over a decade of research has produced one of the largest deep-sea datasets, with 100+ studies and 4,000+ days of seabed-to-surface campaigns.

• Collaboration with leading marine science organizations has generated over a petabyte of data.

• Pilot collection system tests and environmental monitoring have been conducted in the Clarion-Clipperton Zone (CCZ).

Seafloor plume impacts

• In-field data show that over 95% of sediment from seafloor plumes resettles within 1 km of collector tracks.

• High-impact sediment blanketing (>5mm) is limited to hundreds of meters, with zones of influence constrained to several kilometers after 18 months.

• Seafloor plume impacts are highly localized and do not spread thousands of kilometers as previously speculated.
