We have years of first-hand underground mining experience in most countries and across multiple commodities and mining methods. As part of the global SRK group, we have access to specialist expertise, including the ability to bring in highly specialised underground mining skills as needed for each project.
Based on this extensive experience, we have developed an innovative and rigorous mine planning methodology that takes a mineral resource right through to a final comprehensive technical report inclusive of the life-of-line plan and technical-economic model. The methodology first focuses on understanding the mining context of the deposit, followed by assessment of appropriate mining methods and related economic cut-off criteria. Appropriate decisions are made at the earliest opportunity to guide project development.
We recognise the constant need to match changing commodity prices and capital costs with appropriate responses from mining operations: reduction in operating and/or capital costs when prices fall, but on the other hand increase capacity when prices rise. We also understand the requirement to minimise the number of people located in higher cost remote sites, and the increasing preparedness of mining companies to look at projects in any part of the world.
The huge technological advances in underground mining that have occurred in the past five years, including the efficiency of drill and blast, and load and haul systems, have continued to improve mining’s efficiency. The use of mass mining methods is also increasing, including block caving, panel caving, sub-level caving and open stoping. We can assist companies optimise the transition from open pit to underground mining by offering using highly mechanised and often automated solutions.
We are focused on producing optimised mine designs that make the most effective use of capital mine development and equipment, in both short and longer term time frames.
