RESOURCES | Tudor’s Goldstorm update outlines 2.1 billion lb. copper

Tudor Gold shared the results of its updated mineral resource estimate (MRE) for its flagship Treaty Creek gold-copper-silver project, in B.C.’s Golden Triangle, and grades have all increased. The MRE was prepared by Garth Kirkham of Kirkham Geosystems, and JDS Energy and Mining.

Highlights from the MRE include for the Goldstorm deposit indicated resources of 23.3 million oz. of gold-equivalent within 641.93 million tonnes at a grade of 1.13 g/t, comprised of 18.7 million oz. of gold at 0.91 g/t, 112.4 million oz. of silver at 5.45 g/t, and 2.18 billion lb. of copper at 0.15%.

The inferred resource is 7.3 million oz. gold-equivalent within 233.9 million tonnes at a grade of 0.98 g/t gold-equivalent, comprising 5.5 million oz. gold at 0.74 g/t, 45 million oz. silver at 5.99 g/t, and 848 million lb. of copper at 0.16%.

The CS-600 Domain, an intrusive gold-copper porphyry system, hosts an indicated mineral resource of 9.8 million oz. of gold-equivalent within 278 million tonnes at a grade of 1.10 g/t gold equivalent, comprised of 6.22 million oz. gold at 0.70 g/t and 1.98 billion lb./t of copper at 0.32%.

The 1.0 g/t cut-off for all the indicated mineral resource (open pit and underground) measures 15.1 million oz of gold-equivalent at a grade of 1.48 g/t gold equivalent comprised of 12.2 million oz. of gold at 1.20 g/t, 72 million oz. of silver at 7.0 g/t and 1.35 billion lb. of copper at 0.19%.

“These higher cut-off grades exemplify the robust nature of this deposit, including the mineral consistency and thickness of the higher-grade gold and copper mineralized domains that were intercepted during the company’s 2021 and 2022 drill programs,” said Ken Konkin, president and CEO of Tudor Gold.

“These improvements to the Goldstorm deposit are expected to provide an excellent foundation as the company advances the Treaty Creek Project towards an initial economic assessment. Continued definition and expansion drilling will continue in 2023 to target higher gold, silver and copper grades throughout the northern expansion area of the Goldstorm deposit,” he added. CMJ

• RECYCLING | Electra’s battery recycling trial extended

Electra Battery Materials successfully recovered lithium in its black mass recycling trial, conducted at its refinery north of Toronto. Black mass contains highvalue elements, including lithium, nickel, cobalt, manganese, copper, and graphite, that once recovered, can be recycled to produce new lithium-ion batteries. According to data from McKinsey & Com-

Natural Resources

pany, available battery material for recycling is expected to grow by 20% per year, through 2040.

Electra launched its black mass demonstration plant at the end of December 2022 and has processed material in a batch mode, successfully extracting lithium, nickel, cobalt, manganese, copper, and graphite. Electra says the recovery and subsequent production of a technical-grade lithium carbonate at the plant validates the company’s proprietary hydrometallurgical.

As a result of preliminary results achieved to date and interest expressed by potential commercial partners, Electra has decided to extend its black mass processing and recovery activities through June 2023, beyond the company’s initial target of 75 tonnes.

“Recovering lithium from black mass represents a potential game changer for Electra and the North American EV supply chain,” said Trent Mell, CEO of Electra. “From Electra’s perspective, it considerably strengthens the economics of our battery recycling strategy by providing another high-value product we can sell.”
