A Tribute to TerroCore 400

From deep beneath the earth’s crust,
Breaking through rock and time,
Comes a rig you can trust,
With power and rhyme.

Drilling true, working fast,
Unlocking treasure untold,
Built to last and built to last,
For a future bold.

Strong torque, swift pace,
A partner for the bold,
It’s hope for the mining race,
And progress to behold.

Rugged yet smart, the TerroCore 400 goes beyond being just a drilling rig—it’s a symbol of American grit and innovation, brought to life through world-class engineering partnerships.

Dig deeper. Drill smarter. Build stronger.
📍 Made for Miners. Built for America.
