What does half a century of raiseboring experience look like?
We’ve Been Drilling For 50 Years
With half a century of expertise, our team has successfully completed projects which have included: 6’ diameter raises to a total depth of 2,250 feet; 9’ diameter to 1,800 feet; 12’ diameter to 1,250 feet; 16.5’ diameter to 1,540 feet; 20’ diameter to 2,000 feet; and 26′ diameter to 1,450 feet, just to mention a few. We are able to bond our work, thanks to our complete line of equipment (including high pressure air compressors, generators, rig-up trucks, etc.) and our strong financial position. This gives us the capability to perform complete turn-key surface or underground shafts, including steel- or concrete lining, without relying on assistance from our customers or other construction companies.
If you are in the market to hire a mine drilling company, we would be very pleased to be added to your bidders list for any future projects that would encompass our raiseboring capabilities. We invite your inquiry and will provide cost estimates, as requested.
