Ames Mine Earns the 2024 Martin Marietta Diamond
Elite Award

For the team at the Ames Underground Mine, winning the
Diamond Elite trophy was no laughing matter even if, at
first, they thought it was. “I know exactly when I heard the
news: April 1. I know because I thought it was a joke,”
Plant Manager Doug Robey said, smiling. “We worked so
hard for that trophy, so I knew we could win it, but I just
had to be sure I was hearing the news right. I was so happy
when I knew it was serious; it’s hard to describe how proud
I felt.”

Robey and the team of over 100 dedicated ONE team members worked day and night, 24 hours a day, seven days a
week, with two goals: safe work and the Diamond Elite. And it has been a hard-fought battle. In each of the past three
years, Ames Mine has reached Diamond Honor status, narrowly missing the coveted, first-place slot.

“Becoming top-notch in safety, productivity and overall operational excellence doesn’t happen overnight. Believe me, I’ve
been here since 1988; I can tell you this place has changed and grown,” Robey said. “When I took over as plant manager
in 2006, I had one goal. I wanted our team to become #1. And we did it.”

The mine has been operating more than 40 years under Martin Marietta. And while many aspects of the site have
changed, perhaps the most significant aspect that has remained constant to the site’s integrity is its dedication to the
community. Several crew members call Ames, Iowa, their home. Many were born, raised and started a family only a few
miles from the mine. That proximity drives the team to care extra hard about its hometown.

“Doug Robey and I went to high school together,” Quality Control Inspector Kelly Safly laughed. “I grew up here, and I
live here now. Growing up, I was always fascinated with this mine.” Safly said her hometown is a unique place, and she
values working for a company that makes it a point to give back to the community.

“I think it’s important to take care of the environment and be good neighbors so that those in the area appreciate us and
are proud to say they live by a mine. We want them to feel welcomed,” she said. “I like seeing Martin Marietta give back
to my community.”

The Ames Mine crew constantly collaborates with outside organizations to promote Martin Marietta’s values and support
local charities. The most notable of these organizations is the Boys & Girls Club of Story County. The club is a vital part of
the Central Iowa community, with a mission to inspire young people in the area to reach their full potential as
“productive, caring and responsible citizens.” This act of caring for the area’s children inspires the Ames Mine team to
host lunches for the club. The crew regularly provides a hearty meal to more than 50 young club and staff members. In
addition to these visits, the site also donated materials to the club’s new facility, which is currently under construction.

“The partnership between Martin Marietta and the Boys & Girls Club has been very special for us,” said the Boys & Girls
Club of Story County’s Chief Executive Officer Ryan Santi. “It’s fun for the kids, but it also helps them, and our parents,
understand the relationships we have in the community, the possibilities of employment and what we can build
together.”
