GreenRoc Strategic Materials outlined its Amitsoq drilling plan on September 29, 2026, while GreenRoc stock was 35.59 percent below its 52-week high on October 13, 2026. The latest London Stock Exchange quote was GBp 3.80 against a GBp 5.90 high, giving investors a dated measure of the exploration company's position.
Testing validates graphite processing
According to LSE RNS on September 29, 2026, a locked-cycle test produced a graphite concentrate grading 95.20 percent, with overall recovery above 90 percent. The representative sample contained 22.30 percent graphite, and GreenRoc selected GTK Mintec in Finland to process the full 20-tonne bulk sample.
The company plans to use the resulting concentrate as feedstock for its active anode material pilot plant in Denmark. Results from the full-sample processing, including several tonnes of concentrate, are expected before the end of 2026, according to the same dated announcement.
Three dated steps toward Amitsoq
MarketScreener reported on September 17, 2026, that GreenRoc's initial assessment put the planned supply chain footprint at 1.60 kilograms of carbon dioxide equivalent per kilogram of coated spherical purified graphite. On September 29, the processing test delivered the 95.20 percent concentrate. On October 4, Le Monde described Amitsoq as a Greenland graphite project with a deposit grade of 20.00 percent.
What comes next for drilling?
The September 29 announcement said the final two Phase III holes were planned to start in the week beginning October 5, 2026, after a September delay linked to helicopter availability. Drilling was planned for completion by October 16, 2026, while the processing results are expected before December 31, 2026.
GreenRoc's Amitsoq resource totals 23.05 million tonnes at an average grade of 20.41 percent graphite, according to the company announcement. The project also has a 30-year exploitation license granted in December 2025, framing the current drilling as part of a longer development sequence rather than a producing mine.
