Protecting Critical Operations for a Colorado Gold Mine from the Impacts of Lightning

In mining, operational continuity isn’t just about productivity, it’s also about safety, environmental stewardship, and regulatory compliance. For one Colorado-based gold mine operator, lightning posed a serious and underappreciated threat to all four factors.

Facing growing concerns over lightning-related disruptions, the operator turned to Lightning Eliminators & Consultants (LEC) to address two critical risks:

• Preventing process upsets that could lead to cyanide release, and
• Protecting vulnerable water pump houses in a high-exposure area.

The Challenge: Environmental Consequences of Lightning Damage at Gold Mines

The mine uses an cyanide leaching process to extract gold from ore (crushed rock). The ore is placed in large, lined pools where cyanide solutions are applied to leach out gold as the liquid filters through the material and is collected by perforated piping systems. To protect the environment, the operation uses multiple layers of rubber liners with leak-detection pipes between them, so any breach in the upper liner can be identified while a secondary liner prevents contamination from escaping.

Regulators closely oversee water use, treatment, and discharge, requiring strict reporting and imposing fines for any disruptions, missing data, or environmental noncompliance.

Any sudden or unplanned shutdown, such as a lightning-induced event, could create a process upset with potentially severe consequences, including the release of cyanide into surrounding soil or nearby waterways.

The open pit mine sits at approximately 11,000 feet, placing it in a highly lightning-prone area where antennas, utility poles, towers and tall metal structures increase lightning strike risk. The mine runs continuously 24/7, making operational uptime and worker safety critical.

A key vulnerability is a pump house, essential to the leaching operation, which is situated in an elevated, lightning-prone zone. A direct strike or nearby lightning-induced electrical surge could disable the pump, triggering cascading operational and environmental risks, including the potential for an accidental discharge of cyanide-contaminated water.

The stakes were clear: a single lightning event could result in environmental damage, regulatory scrutiny, expensive fines, and costly downtime.

The Solution: A Targeted Lightning Prevention Pilot

LEC recommended starting with a focused pilot project to protect a key exposed and vulnerable asset – a  pump house. By installing Spline Ball Terminals (SBT’s) and surge protectors, LEC aimed to “prevent” lightning attachment in the protected area, rather than simply redirecting it after the fact.

The results were immediate and measurable.

Following installation, the pump house experienced zero lightning-related disturbances. Storm activity that previously posed a threat no longer resulted in interruptions, equipment damage, or operational anomalies.

Expansion: From Pilot Project to Site-Wide Lightning Protection for Gold Mines

Impressed by the performance of LEC technology with the pump house, the mine operator quickly recognized the broader implications for the entire facility.

What began as a single-site pilot evolved into a comprehensive lightning protection strategy for the entire mine. LEC technology was expanded across critical areas of the operation, providing a unified layer of protection designed to:

• Maintain continuous operations during storm activity
• Reduce the risk of process upsets involving cyanide
• Protect personnel and sensitive infrastructure
• Minimize environmental and regulatory exposure

The expanded lightning protection system included additional Spline Ball Terminals that replaced traditional lightning rods on many structures, Spline Ball Ionizers (SBI’s) on towers and poles, and Surge Protection Devices (SPD’s)

The Result: Reduced Risk, Increased Confidence

By proactively addressing lightning risk, the operator transformed a major vulnerability into a controlled and manageable factor. The implementation of LEC’s lightning protection solutions delivered:

• Greater operational uptime during thunderstorms
• Enhanced environmental protection safeguards
• Increased confidence in process stability
• Long-term cost savings by avoiding damage and downtime

Take Control of Your Lightning Risk

Lightning doesn’t have to be an unpredictable threat to your operation. Whether you’re managing hazardous materials, critical infrastructure, or high-value assets, the right protection strategy can make all the difference.

If your facility can’t afford unplanned downtime or environmental risk, it’s time to rethink your approach to lightning protection.
