Manifold Consult provides geological contracting services with a difference; we don’t just send out contract geologists to help with a program, we make sure our professionals have excellent support and come with the required equipment, hardware and software.

With a pool of international talent creating the core members of our team and over 30 specialist and generalist geologists in our network, Manifold is able to find the right person to fill each of our client’s specific and individual needs. We work hard to place the right geological contractor with the right client, and once this person is in place they are provided with on-going support from our technical manager and our office based logistical team. We do more than just fill a gap in our client’s busy exploration and mining programs. Manifold Consult adds genuine value to any project and provides cost effective geological contracting with a difference!
