Cost Model Service

Roskill’s Lithium Cost Model Services are designed to provide miners, financial institutions, governments and other industry stakeholders with an in-depth understanding of the lithium supply chain, from the discovery of new mineral resources through to the production of battery grade material.

The product offering comprises two modules. One of which focuses on the existing extractive operations and new projects, and a second which examines the refining sector and provides a granular look into the cost of producing refined battery-grade carbonate and hydroxide from various lithium feedstocks.

These modules offer critical tools in the evaluation and benchmarking of existing extractive operations, new projects and downstream refineries.

Lithium Cost Model Service — Extractive

The Lithium Cost Model Service (Extractive) focuses on the outlook for lithium mine production and the operating cost and capital expenditure requirements of the existing lithium operations and development projects which are currently being evaluated within the brine, hard-rock and clay sectors.

The service currently contains 67 fully costed operations and development projects while also tracking an additional 33 exploration stage projects. Each costed model provides a Discounted Cash Flow costing approach over the Life of Mine of each operation.

Service Contents & Capabilities

Comprehensive coverage of operating mines and projects within the lithium industry; including data on location, ownership, reserves, resources, capacity, production, operating and capital costs.

Overview of current lithium mine supply and asset-by-asset brine, mine and project production from 2010 to 2040; providing users with the capability of building their own granular forecasts for lithium production.

Industry cost curves on multiple metrics, including All-In Sustaining Cost, which enables users to better understand the true economics at play within this emerging industry.

Breakdown of brine extractions rates, brine concentration, mining volumes, ore grade, process plant throughput, recovery and production on a year‑by‑year basis.
Information on greenfield, brownfield and expansion projects capital expenditure requirements.

Tools to analyse global reserves & resources; including exploration stage projects.
Custom cost curve tools and other analysis which is invaluable for project benchmarking.

Service blog outlining the latest developments in the sector and updates to the analysis contained within the service.

Detailed operating cost analysis, with an annualised breakdown of:

  • Brine: Extraction costs, feedstock transport, plant processing, G&A, realisation/selling expenses, royalties payments and other sustaining/stay-in-business expenses.
  • Mining: Mining, concentrator, G&A costs, royalty payments, realisation/transport expenses and other sustaining/stay-in-business expenses. It also includes a high-level overview of spodumene refining costs to benchmark spodumene operations against other projects and brine operations producing a refined lithium product.

Lithium Cost Model Service — Refining

The refining model of the Lithium Cost Model Service takes a deep-dive into the cost makeup of the lithium refining sector, and the operating cost and capital expenditure requirements for the production of refined battery-grade lithium carbonate and hydroxide from spodumene and other intermediate feedstocks.

Service Contents & Capabilities

Overview of refined lithium carbonate and lithium hydroxide supply. including plant-by-plant production and capacity forecasts to 2030; providing the user with the capability of building their own granular forecasts for refined lithium output.

Detailed cost analysis, including extensive granular cost data, which is broken down by feedstock, labour, power & utilities, fuel, reagents, other processing consumables, waste disposal, selling and G&A costs.

Information on project capital expenditure requirements.

A summary report providing an overview of the analysis; allowing users to quickly digest the intricate analysis within the service.

Custom cost curve tools and analysis which are invaluable for project benchmarking.

Technical appendices giving an insight into the various processing flowsheets to produce lithium carbonate and hydroxide.
