Class 1 Nickel and Technologies has released an updated mineral resource estimate for the Dundonald North nickel sulphide deposit, part of the broader 3,093-hectare Alexo-Dundonald project near Timmins, Ontario. The updated estimate shows a 31.4% increase in out-of-pit inferred resources, totaling 2.5 million tonnes at 0.75% nickel, along with significant gains in contained copper and cobalt. Across the four deposits in the project, total mineral resources now stand at 3.4 Mt indicated and 6.6 Mt inferred, using various NSR cut-offs. The Dundonald North and South deposits remain unmined, offering strong exploration potential, with further drilling planned to upgrade resources. CEO David Fitch emphasized the strategic importance of these deposits and highlighted additional exploration targets from untested EM anomalies and historical nickel sulphide occurrences. The company plans to launch an exploration program supported by airborne geophysics, historical drilling, and new remote sensing surveys to further define and expand the project’s resource base.

High-Grade NPI Smelters Face Profit Pressure Amid Flat Raw Material Prices and Limited Nickel Ore Decline

[SMM Nickel Flash News] Based on the cash cost of high-grade NPI calculated using nickel ore prices from 25 days earlier, profits at high-grade NPI smelters came under pressure during the week, with the sector as a whole remaining in a state of losses or marginal profitability. It is expected that next week, prices of auxiliary materials on the raw material side may remain flat, while the decline in nickel ore prices will likely be limited. High-grade NPI prices will still be under pressure amid back-and-forth negotiations between upstream and downstream, and smelter profits will be unlikely to see any significant improvement.
