Cash costs in mining represent the direct costs incurred during the extraction and processing of ore at the site level. These costs are calculated per unit of output and typically include expenses such as:
Key Facts
- Definition: Cash costs are the regular direct costs incurred in the mining and processing of ore. The specific definition may vary between companies, but it generally includes costs such as transport, refining, administration, and royalties.
- Scope: Cash costs are calculated at the site level and represent the costs of production per unit of output. They typically exclude non-cash costs like depreciation and amortization, as well as costs not directly related to the site, such as head office expenses.
- By-product valuation: When a mine produces by-products, such as gold from a copper mine, the value of those by-products is deducted from the cash cost of the primary metal. This is a common accounting treatment for by-products in various industries.
- Exclusions: Cash costs generally exclude certain expenses, including taxes, exploration costs, depreciation, depletion, and financing.
- Transport
- Refining
- Administration
- Royalties
Scope
Cash costs are specific to the mining site and do not include non-cash expenses like depreciation and amortization. Additionally, costs not directly related to the site, such as head office expenses, are excluded from cash cost calculations.
By-Product Valuation
When a mining operation produces by-products, such as gold from a copper mine, the value of those by-products is deducted from the cash cost of the primary metal. This deduction aligns with standard accounting practices for by-products in various industries.
Exclusions
