Nouveau Monde Graphite Starts Construction of Matawinie Mine Project in Quebec

By

Nouveau Monde Graphite (NOU.TO) has started construction of the Matawinie mine project in Saint-Michel-des-Saints, Quebec, according to a report released late Tuesday.

Canadian Prime Minister Mark Carney, Quebec Minister of Economy, Innovation and Energy Bernard Drainville, partners, elected officials and key community stakeholders were present at the groundbreaking ceremony.

The project is in line with the priorities of both Canada and Quebec to establish one of the largest integrated natural graphite production platforms in the G7 and to secure critical mineral supply chains.

The project was designated as a major project of national interest by the Canadian government in November 2025.

Construction and commissioning of the Matawinie mine project are expected to take about 31 months, with full commercial production scheduled by the end of 2028.

The project has an estimated average annual production of 106,000 tonnes of graphite. Production is supported by diversified commercial agreements, including with Panasonic Energy, the Canadian government and Traxys North America, covering more than 70% of expected production.

In addition, the company aims to reach a final investment decision in the second half of 2026 for its battery material plant in Becancour.

According to Carney, the mine is expected to eventually pump nearly $2 billion into the economy and add 1,000 jobs.

"That is eight times - eight times - Canada's total graphite production right now. It will make us stronger. It will make our international partners more resilient, and above all that, it will build a supply chain," the prime minister said from the Nouveau Monde Graphite (NMG) mining site near Saint-Michel-des-Saints, Quebec, north of Montreal.

Hydro One Files Applications With Ontario Energy Board for Two Major Transmission Lines

Hydro One (H.TO) after trade Tuesday said it filed leave-to-construct applications with the Ontario Energy Board for approval to build the Northeast Power Line and the Longwood to Lakeshore Transmission Line.The Northeast Power Line will be a 500-kilovolt transmission line running between Greater Sudbury and near Wharncliffe. The roughly $1.8 billion project is expected to increase electricity transfer capacity between northeast and northwest Ontario by about 900 megawatts and is targeted for completion in 2029, the company said.The Longwood to Lakeshore Transmission Line is also a 500-kV transmission line that will connect Longwood TS in Strathroy-Caradoc to Lakeshore TS in Lakeshore. The roughly $1.2 billion project is expected to deliver about 550 MW of electricity to the region, supporting local jobs and industries. It is expected to be completed in 2030, the company said.Hydro One also said nearby First Nations will have the opportunity to invest in a 50% ownership stake in the transmission line portions of both projects through the company's First Nation Equity Partnership Model."Electricity demand in Ontario is increasing. These lines are part of one of the largest transmission line infrastructure investment portfolios in Canada that we are advancing together with First Nations," Executive Vice President, Capital Portfolio Delivery, Ryan Docherty said.

Update: Marimaca Copper Says Marimaca Project on Track for 2026 Investment Decision

Marimaca Copper (MARI.TO) after trade Tuesday updated permitting and development work at its Marimaca Oxide Deposit (MOD) project in Chile, saying key milestones remain on track ahead of a planned final investment decision in 2026.The company submitted key sectorial permit applications in April, and expects approvals in the fourth quarter. Marimaca also received authorization on May 13 to connect the project to the 110-kilovolt El Lince power line located near the site. The company saqaid early site work, including road and highway upgrades, is set to begin in June.In addition, the company signed a non-binding memorandum of understanding with a sulphuric acid supplier in the Mejillones industrial area to explore a potential joint venture for acid supply."We have continued to systematically de-risk the MOD across the key workstreams required to support a construction decision. Our permitting, surface rights and engineering progress, and ongoing engagement with project financing stakeholders all represent important milestones as we move steadily toward construction-ready status and a future FID," Chief Executive Hayden Locke said.Earlier Tuesday, the company reported new assay results from the Pampa Medina deposit about 28 kilometers east of the Marimaca oxide deposit.The results from the exploration drilling program at the deposit further validate the consistency of both oxide and sulphide mineralization across the high-grade central zone.Step-out drilling continues to expand the mineralized sedimentary basin, with high-grade intercepts reported over 300 meters from previous drilling in the southwestern area of interest.Drill hole SPRD-06 yielded a broader intercept of 424 meters of 0.58% copper and 2.2 grams per tonne silver from 424 m, containing five high-grade, stacked mantos.Other highlights include 166 meters of 0.50% copper and 3.9 g/t silver from SPRD-02, 30 meters of 1.00% copper and 7.3 g/t silver from 536 meters from SWRD-05, 145 meters of 0.41% copper and 1.9 g/t silver from 286 meters from SPRD-01, and 14 meters of 0.31% copper from 52 meters from SPRD-03.The company's shares closed down $0.22 to $7.95 on the Toronto Stock Exchange.

Greenlane Renewables Reports 99.5% Methane Recovery in NRU Technology Testing

Greenlane Renewables (GRN.TO) said Tuesday testing of its proprietary Linear Nitrogen Rejection Unit (NRU) technology achieved methane recovery rates of up to 99.5%.The company said the technology is part of its next-generation Cascade LF landfill-gas upgrading system, which is designed to turn landfill gas into pipeline-quality renewable natural gas while maximizing methane capture at a lower cost.The system removes nitrogen from landfill gas using a pressure swing adsorption process that requires fewer and smaller components than traditional systems. For landfill gas with higher nitrogen levels, the modular system can add more adsorption beds and compression stages while maintaining the same design, according to the statement."Results from the testing were slightly better than Greenlane's initial performance expectations and correlated well with modeled results calculated based on adsorption fundamentals," the company added.Greenlane shares closed up $0.005 to $0.22 on the Toronto Stock Exchange.
