LIFE CYCLE GEO

Life Cycle Geo (LCG) was founded in 2018, with the primary aim of providing innovative geoscience solutions to the mining and oil and gas industries across the project life cycle. LCG provides a broad range of technical services in the areas of geology, geochemistry and the data sciences.

In addition to these services, it is a primary aim of LCG to help clients optimize and automate their projects and realize significant long-term project cost savings using innovative artificial intelligence-based tools such as machine learning and deep learning. LCG company founder Dr. Tom Meuzelaar was the recipient of Golder Associates’ inaugural Technical Excellence and Innovation Program award for his development of a workflow for the management of mine materials through all stages of the project life cycle using structured drillcore assay and unstructured hyperspectral mineralogy in combination with unsupervised classification and supervised machine learning techniques. LCG believes that most drillcore assay data is heavily underutilized and can be used to unlock significant additional project value for our clients.

At LCG, our clients come first. We commit to:

  • Carefully listening to your needs before offering a solution
  • Delivering a quality product on time and within budget
  • Providing an appropriate level of communication throughout the project duration
  • Remaining flexible and adaptable as project and client needs evolve
  • Conducting our work with the highest level of professionalism, integrity and care
