An inspection of the Mollie Kathleen Gold Mine in Cripple Creek prompted by an elevator malfunction that killed tour guide Patrick Weier and left 23 stranded for hours has wrapped up, according to a news release Wednesday from the El Paso County Sheriff’s Office.

The mine closed in the 1960s and has since been turned into a tourist destination that takes guests on a vertical descent 100 floors below ground, according to its website. Tours are done at 1,000 feet, but the elevator shaft is deeper than that.

Twelve individuals spent upwards of six hours at the bottom of the mine Oct. 10 with no idea of what had happened with the malfunction above.

At the time, officials were unable to say what went wrong with the elevator. After an inspection that showed no debris was blocking rails or cables, and a test run up and down, it was able to be used to bring everyone up.

The initial call came in around noon and by 7:15 p.m. everyone had made their way to the top.

The Sheriff’s Office’s investigation determined the incident to be  operator error as opposed to current mine practices or equipment malfunctions. Weier’s death was ruled accidental.

The state’s multi-agency safety inspection concluded in December, according to the news release. A cease-and-desist order that was placed on the tourist mine has been lifted.

Officials said the state investigation looked at the mine’s ground control, inspection and training records, ventilation, fire prevention and control, communication systems, personnel hoisting mechanisms and procedures, and more.

State mining inspectors determined the tourist mine meets the requirements of the Regulations for the Mine Safety and Training Program. There is no danger to the public or employees of the mine, the news release stated.

The mine is able to resume operations for the upcoming tourist season, although it is not clear when the exact reopening date will be. The season is typically May through the second weekend in October, weather permitting.

A GoFundMe link has been shared on the Mollie Kathleen Gold Mine’s website to support Weier’s son, Anthony. Donations have been put into a trust to directly go toward Anthony’s future. By mid-January, $73,097 has been raised.

The tourist mine had a brief history of similar incidents decades ago. In the summer of 1994, an elevator failed twice, stranding tourists underground for hours, according to a report by The Colorado Springs Gazette Telegraph.

On June 17 that year, 13 tourists spent 12 and a half hours stuck in the mine after a metal elevator pulley broke, causing a cable to slip off the wheel, according to the report. It happened again the following month, and 50 tourists were stuck for about four hours.

In both cases, no injuries were reported and the mine was closed for only a few days after each malfunction.
