Specialised Ore Evaluation Services

Technical Auditing & Compliance

Golder has completed numerous Mineral Resource/Reserve audits in many commodities, ranging in size from smaller first-time resource estimates to mulitiple property resources/reserves for large global producers.

Efficient Due Diligence studies are also a mainstay of the Golder global resources and reserves team. Timely but comprehensive review of data and technical reports provide clients with a risk based analysis on properties.

Mining Grade Control & Ore Block Optimisation

Golder has developed and utilises a mining grade control system based on Ore Block Optimisation (OBO). Its modules assist the mining geologists in determining the most cost effective method of supplying the ore to the mills.

The sampling data is modelled using geostatistical conditional simulation, with the ore block boundaries optimised to meet specified mine management criteria. Using this system, mining blocks can be generated quickly, repeatable and consistent with mining controls such as cut-off grade.

Global Network, Local Solutions

Golder's Resource Evaluation Services Group utilises Golder professionals in multiple disciplines around the world as needed. Online collaboration, seamless databases and cross industry knowledge systems give them access to the latest technological advances and global best practices that can directly benefit your project.

And with local offices in or near every major exploration or mining district in the world, Golder's consultants have ready access to local knowledge and support as needed to mobilise mineral resource evaluation projects efficiently and economically.
