Silver Supply Gets a Boost as La Colorada Expands
Pan American Silver’s updated economics for its flagship Mexican mine point to lower costs and a longer operational life - a meaningful supply signal with silver trading near $67.
What to know
-
Pan American Silver has outlined improved economics for the La Colorada skarn project in Mexico, with lower all-in sustaining costs and an extended mine life.
-
Silver is currently trading at $67.22/oz with a gold/silver ratio of 65.8, suggesting the white metal remains well-supported relative to gold.
-
Mexico continues to anchor global silver supply despite periodic regulatory uncertainty, and this expansion reinforces the country’s centrality to the market.
What happened
Pan American Silver has refreshed the economic outlook for its La Colorada mine expansion in Zacatecas, Mexico. The updated study shows lower all-in sustaining costs, a longer mine life, and improved production forecasts for the skarn deposit beneath the existing underground operation. The numbers are materially better than previous estimates.
The La Colorada skarn has been a project-in-waiting for years, with Pan American navigating permitting, infrastructure buildout, and the complexities of developing a polymetallic deposit at depth. The revised figures suggest the company has found efficiencies in the mine plan that meaningfully de-risk the expansion. Lower capex intensity per ounce of silver equivalent produced is the headline takeaway. Silver is trading at $67.22/oz - a price that makes marginal projects look attractive and good projects look exceptional.
Who’s involved
Pan American Silver is the world’s second-largest primary silver producer, and La Colorada is one of its cornerstone assets. The company operates across the Americas, but Mexico remains its most significant jurisdiction for silver output. The updated study positions La Colorada as a longer-duration, lower-cost contributor to the portfolio.
Analysts covering Pan American have broadly welcomed the revision. The consensus view appears to be that the improved economics strengthen the investment case at a time when silver equities have lagged the underlying metal’s performance. The gold/silver ratio sitting at 65.8 suggests silver still has room to outperform gold on a relative basis, which would further enhance the economics of primary silver operations like La Colorada.
Mexico’s mining regulator is the other key player to watch. The country has tightened oversight in recent years, and any expansion project in Zacatecas carries some jurisdictional risk. Pan American has operated in Mexico for decades and has navigated prior regulatory shifts without major disruption.
Why it matters
Silver’s supply picture is tighter than many market participants appreciate. Global mine supply has been essentially flat for several years, even as industrial demand - particularly from solar photovoltaics and electrification - has surged. Any project that credibly adds ounces at competitive costs matters for the medium-term balance.
La Colorada’s improved economics are significant because primary silver mines are rare. Most silver is produced as a byproduct of gold, copper, and lead-zinc mining. When a dedicated silver operation extends its life and lowers its cost curve, it signals that the supply response to higher prices is beginning to materialise - but slowly. The lag between price signals and new production reaching the market remains measured in years, not quarters.
With silver near $67, the economics of this expansion look robust. Silver averaged roughly $25 in 2023 and has nearly tripled since. Producers who locked in expansion plans during leaner times are now reaping the benefit of a transformed price environment.
What comes next
Pan American’s timeline for bringing the skarn into full production is the first thing to track - any slippage would tighten the supply outlook further. Mexico’s regulatory posture heading into the second half of 2026 matters, particularly around water use and environmental permits in Zacatecas. Whether silver’s current price level incentivises other dormant projects to restart is the broader question. The industry needs sustained prices above $50 to justify greenfield development, and at $67 that threshold is comfortably cleared. If La Colorada’s improved economics encourage peers to dust off their own expansion studies, the supply response could accelerate into 2027-2028.
