Innovation at Depth – Go with the Flow: Mine Planning to Reduce Impact
TMC mapped how sediment plumes follow seabed contours downslope. Sweep mining now covers 500 to 1,000 meters instead of 80 to 100 km runs.
Deep Sea Joins U.S. Defense Industrial Base
Deep Sea Minerals named the CCZ its top area outside EEZ waters. A Trump executive order opened a path to commercialization there.
Innovation at Depth – Midwater Release: Less Up, Less Down
TMC's system adds a hydrocyclone step to filter fine sediment. Sediment returns at 2,000 meters depth, below the top 1,000 meters where most biomass lives.
Innovation at Depth – Calming the Current
Allseas' diffuser returns mining discharge water near the seabed. It recovers up to 95% of sediment before the riser stage.
Webinar: Navigating the Hidden World of Cultural Significance in the Deep Ocean
SEARCH archaeologist Piscitelli hosted a webinar on deep sea mining. Only 1.6% of the 150,000 known shipwrecks sit at mining depths.
The Metals Royalty Company Introduction
TMCR holds a 2.0% gross royalty on TMC's NORI nickel deposit. Speakers peg the deposit's grade at roughly 10 times copper-equivalent mines elsewhere.
Innovation at Depth – Smarter Separation At The Source
Allseas is developing a Hopper 2.0 to separate nodules from sediment. The design keeps 95-98% of sediment suspended for return to the seafloor.
Deep-Sea Nodule Collection – Then and Now
TMC's video compares 1970s nodule collection with its new system. Allseas built the new miner to cut impact, fifty years after the tech began.
Testing the Eureka III Conveyor System | Full-Scale Prototyping at Impossible Metals
Impossible Metals tested a full-scale Eureka III conveyor mockup. The team built it from 3D-printed parts and PVC pipe.
Carbon Sequestration – What does the data tell us?
TMC's Michael Clarke says most ocean carbon sits in the water column. Less than 4% is stored on the seafloor.
