Testimonials


The Technology Development group supporting Albian mines at CNRL had been a M A Okane client for a number of years, and I am very pleased with their services.

For our field projects Okane provides a number of support activities including field instrumentation, survey and monitoring. I found the Okane team to be very active, energetic and flexible to adjust to the client’s need on a relatively short notice which is a core requirement for our projects. I highly recommend M A Okane’s services, and expect that they would continue their excellence in the future.

CNRL – Albian Mines


Your team has advanced mine closure planning at our site more in the last month than we’ve seen in the last five years.
