Colorado's Wisdom Rides built Miner Mike. They have built dozens of coasters under the "Miner Mike" model name. Some versions have a tire-lift, others have an electric motor in the train that pulls the cars up the lift hills, while some models are electrically powered all the way around the track.
For the record, I don't count the electrically powered models as coasters, so they are not pictured on CoasterGallery.com. I only have pictures of the gravity powered coasters.
