Cambria Gold Mines (TSXV: CAMB; US-OTC: CAMVF) is aiming to bring its Premier gold mill in northern British Columbia back online by late 2027. The company’s previous attempt to restart the facility was cut short when underground ore feed proved inadequate to sustain operations. Now, Cambria plans to recommission the mill, which has a designed capacity of 2,500 tonnes per day.
The announcement comes as gold prices remain elevated, making the economics of restarting idled assets more attractive for junior miners. However, the success of any mill restart depends on securing a consistent and sufficient supply of ore from the mine.
The Premier mill
The Premier mill is a gold processing plant located in the prolific Golden Triangle region of British Columbia, an area known for its historic and active mines. The facility was originally built to process ore from the adjacent Premier mine, which operated intermittently over the past century. Cambria acquired the asset as part of a strategy to restart production at the site.
With a throughput capacity of 2,500 tonnes per day, the mill is sized to handle a moderate-scale operation. For context, many modern gold mills in Canada process between 3,000 and 5,000 tonnes per day, but the Premier mill’s smaller footprint can be an advantage for a project with a defined resource base.
Previous ramp-up challenges
Cambria’s first attempt to restart the mill was hampered by a shortage of underground feed. Mining operations had not yet developed enough stopes to deliver ore at the rate needed to keep the mill running efficiently. This is a common challenge in underground mining: it takes time to establish production headings and achieve steady-state output.
The company had to halt the ramp-up and reassess its mine plan. The new target of late 2027 suggests Cambria is allowing sufficient time to develop the underground workings and build a reliable ore stockpile before the mill restarts.
Path to restart
Recommissioning a mill that has been idle requires significant capital and planning. Cambria will need to refurbish equipment, secure permits, and ensure the mine can deliver consistent feed. The company has not disclosed the estimated cost of the restart, but such projects typically run into tens of millions of dollars for a mill of this size.
The timeline to late 2027 implies a multi-year development phase. Investors will watch for milestones such as updated resource estimates, permitting progress, and financing arrangements. The company’s shares trade on the TSX Venture Exchange and the US OTC market, providing liquidity for retail and institutional holders.
Gold prices, which have traded well above $2,000 per ounce in recent months, provide a supportive backdrop. However, the viability of the restart ultimately hinges on the grade and quantity of ore that can be delivered to the mill. Cambria will need to demonstrate that the mine can sustain the mill’s appetite before the restart can succeed.
