For many attending last week’s Western Nevada Development District (WNDD) summit, mining is something discussed in panels, reports, and economic projections. But in this case, on day one of the conference they were able to see mining up close and personal.
As part of the summit, regional leaders boarded buses and headed up Rochester Canyon for a guided tour of the Coeur Rochester mine, one of the largest employers, and economic drivers in Pershing County.
Tour attendees were able to observe firsthand, a constantly evolving industrial system measured in miles, millions, and long-term bets on the future.
The tour walked participants through a major recent expansion at the site, including a three-stage crushing system and new processing infrastructure representing roughly a $750 million investment.
At the primary crusher, haul trucks dump rock the size of small boulders into machinery designed to reduce it to just a few inches. From there, the material moves through a series of crushing and grinding stages before being placed on heap leach pads, where precious metals are extracted through a chemical process.
The scale is hard to overstate.
Each haul truck carries hundreds of tons of material. Tires alone can cost tens of thousands of dollars apiece. Conveyor systems stretch more than a mile across the site, connecting one stage of the process to the next.
“This isn’t Disneyland,” General Manager Tim Dimock, told the group at the outset. “There’s a lot of powerful machinery out here that doesn’t stop very quickly.”
Company officials told attendees the operation currently has roughly 200 million ounces of silver in reserve, supporting an estimated 15-year mine life, with additional exploration ongoing to extend that timeline.
Unlike higher-grade mines, Rochester operates on volume.
Nearly all material mined is considered ore, with relatively little waste compared to traditional operations. Lower-grade material that may have been discarded in the past is now increasingly viable as technology improves and metal prices rise.
Even after mining ends, the site will continue producing through leaching operations for years afterward.
That long horizon is paired with constant reinvestment. Company officials said they spend millions annually on exploration and planning, continuously adjusting operations based on changing market conditions and resource data.
The tour also addressed one of the most common public questions around mining: how the process works and how it is managed.
At Rochester, a dilute cyanide solution is used to separate gold and silver from ore. The system operates as a closed loop, with fluids captured, recirculated, and reused across the site.
Officials emphasized the operation is a “zero discharge” facility, meaning process water is contained within the system, even during major weather events.
The site is regulated by multiple agencies, including federal mine safety regulators and state environmental authorities, with frequent inspections and permitting requirements covering everything from air quality to reclamation.
Today, the mine employs more than 370 workers, though fewer now live in Pershing County than in the past.
Officials said only about a third of employees currently reside locally, with many commuting from surrounding areas including Reno, Winnemucca, and beyond.
Housing and workforce availability have become growing challenges that mirror broader discussions at the WNDD summit around rural infrastructure and economic growth.
Company leaders said they are exploring ways to expand housing options and make it easier for workers to live closer to the site.
At the same time, mining remains a cornerstone of the local economy, both through direct employment and broader community investment.
The tour also highlighted the long history of mining in Rochester Canyon, where operations date back to the late 1800s.
At one time, more than 10,000 people lived in the Rochester mining district, with entire communities built around early silver production. Today, little remains of those original settlements, many of which were lost to time and wildfire.
Modern operations now span thousands of acres, with activity continuing to expand into new areas as additional resources are identified.
For attendees, the tour grounded the broader conversations happening at the summit.
Discussions about energy demand, infrastructure, workforce, and economic development all connect back to operations like Rochester. Issues that are large, complex, and deeply tied to the future of rural Nevada.
Those on the tour agreed – it’s one thing to talk about mining in a conference room, it’s quite another to stand at the edge of a pit and watch a 200-ton truck roll by, realizing just how much of the region’s economy is built on what’s happening in that canyon.
