Hudbay Minerals executives and British Columbia's Minister of Mining and Critical Minerals, Jagrup Brar, stood at the edge of a pit in the Similkameen Valley on June 16 and watched the first shovel bite into New Ingerbelle, a copper deposit that will reshape the economics of the company's flagship Copper Mountain mine for the next fifteen years. The groundbreaking marks the moment when 750,000 tonnes of proven copper reserves move from a government permit to actual construction, with active excavation already underway on access roads, a bridge crossing the Similkameen River, and a haul road that will link the new pit to existing mill infrastructure. The scale is not flashy, this is not a new mine, but a pit expansion at an operating property, yet the margin implications matter: New Ingerbielle is designed to access ore with a stripping ratio (waste rock moved per tonne of ore extracted) three times lower than the current mining areas at Copper Mountain, a mechanical advantage that changes per-tonne production costs in a way that 750,000 tonnes of tonnage alone would not.
Permitting for New Ingerbelle closed in February 2026 after a review process that included consultation with the Upper Similkameen Indian Band and Lower Similkameen Indian Band, both of which reached refreshed participation agreements with Hudbay earlier that month. The provincial government's inclusion of New Ingerbelle on its priority resource projects list on April 29, 2026 signaled that regulatory risk was no longer the binding constraint, the binding constraint is now execution on the 18-month construction schedule to move the haul road and bridge from blueprints to finished concrete. CEO Peter Kukielski framed the expansion as 'a critical pillar of Hudbay's long-term growth strategy in British Columbia,' language that translates to: without New Ingerbelle, Copper Mountain faces resource depletion and mine closure by the mid-2030s. With it, the mine runs past 2040 and delivers sustained copper production across a decade of rising global demand.
The reserve estimates published alongside the groundbreaking projected 900,000 ounces of gold and 5.5 million ounces of silver as co-products alongside the copper, meaning the pit does not live or die on copper spot price alone, but copper remains the economic driver, and that stripping ratio advantage is where the bet lives. A pit with lower stripping ratios survives lower copper prices; it also generates higher margins at the same price. In a North American copper market where the Porphyry deposits in Arizona and British Columbia are aging and require deeper pit walls and higher per-tonne waste volumes, a deposit that inverts that curve is a structural competitive advantage. Hudbay did not disclose the capital cost of the New Ingerbelle build or the timeline to nameplate production, but infrastructure construction (bridge, road network, mine camp expansion) typically requires two to three years for a pit of this scale, placing New Ingerbelle in copper production ramp sometime in late 2028 or early 2029.
The 800-plus jobs protected by the expansion are not trivial for the Princeton, BC region, but they are also contingent on the mine's margin economics remaining defensible as copper cycles. If the deposit generates sufficient free cash flow at a $3.50-to-$4.00 per-pound copper price range, the jobs stay; if margins compress below that, the timeline to closure resets. The real read: New Ingerbelle is a bet that Hudbay can lock in a decade of lower-cost copper before the pit is forced to walk away from the property entirely. Watch three markers over the next 18 months. First, the completion date on the Similkameen River bridge and haul road, any delay signals construction cost pressure or environmental constraint surprises. Second, whether Hudbay announces a detailed production schedule and all-in sustaining cost (mining, milling, and administration cost per pound of copper) for New Ingerbelle ore by Q4 2026, that number will tell whether the stripping ratio advantage translates to the margin improvement the company is betting on. Third, whether any of Hudbay's large institutional shareholders push for faster ramp or cost guidance, cost overruns on a capital project this scale can erase years of margin improvement before they arrive.
