Access our global knowledge when planning a major capital purchase, parts or support agreement and join the list of satisfied clients who have been surprised at the value we have created while nurturing long term supplier relationships. Calsta approach this area very differently to most other companies.

Calsta focus on making good commercial decisions with the projects long term strategy in mind; weighing up the best NPV options, capital constraints and risk mitigation to determine the optimum outcome for the project.

Decisions on Capex and Opex are not usually mutually exclusive. Assets (Capex) normally require regular maintenance, repairs and consumable items (Opex) to operate over the assets economic life. Depending on the asset type, operating expenditure can be many multiples of the capital cost of the asset over its economic life.

A capital item which seems expensive today can actually provide the lowest Total Cost of Ownership (TCO) if Opex items such as maintenance, parts and consumable costs are lower than other alternatives being considered.

Feasibility Studies

From pre-feasibility (PFS) to definitive feasibility (DFS) Calsta have the tools to assist. Our cost models are developed with the aim of providing a tool which can be easily peer reviewed or audited by third parties.

We develop all cost models in a manner which allows the project team to utilise the model for cost management during the project phase with all codes usually aligned to longer term operational requirements. This approach allows the operations team to easily transition this same model to become the sustaining capex and opex budgeting tool.

Turnkey Tendering Services

From a single vendor purchase to a complex multi supplier purchasing agreement Calsta have the tools and specialist skills to manage this process.

Calsta have detailed systems and procedures to ensure all scenarios are covered from design, point of manufacture through to final vendor field performance testing and handover to our client.

Procurement Strategy

Our strategic approach focusses on cost being a key driver as per most traditional models. However Calsta’s approach gives consideration to developing a strategy focussing on broader objectives such as surety of supply and lowest Total Cost of Ownership (TCO).

We deploy our tools to identify the Zone Of Possible Agreement (ZOPA) and the Best Alternative To Negotiated Agreement (BATNA). A member of Calsta’s team has studied under internationally recognised negotiating experts Deepak Maholtra and Max H Bazzerman at the Boston Campus of Harvard Business School.

Optimise Critical Spares Holdings

Ensuring the right spare parts are on site at the right time is critical for all operations. Having too few spare parts on site can cause excessive machine down time and lost production tonnes; having too many spare parts on site can cause parts to deteriorate before fitment and increased holding costs.

Calsta will optimise your inventory through rationalisation of stock,  Just In Time (JIT) supply, vendor held stock options and accessing third party suppliers.

Benchmarking And Cost Modelling

Benchmarking is a valuable tool for understanding current performance against planned or expected performance. Benchmarking is used to evaluate internal services and external services against cost and execution parameters.

Calsta have the ability to build up cost and performance models using both zero base methodologies and comparative modelling utilising our data base and global experience.

Mine Planning

Let us work with your team to identify where and how improvements can be made to your current mining scenario. Our team can assist with Tactical, Strategic and Life of Mine design and planning.
