Total Cash Cost: Gold Mining Production Cost per Ounce

Total cash cost is a non-GAAP mining metric used to express the cash-oriented cost of current metal production, commonly on a per-ounce basis for gold.

A simplified presentation is:

1Total Cash Cost per Ounce
2= Adjusted Current Production Costs ÷ Ounces Sold or Produced

The numerator and denominator are issuer-defined, so the reconciliation matters.

What total cash cost commonly starts from

Gold miners often begin with production costs or cost of sales and then adjust for items such as:

• depreciation and amortization;
• by-product credits;
• royalties or production taxes;
• treatment and refining charges;
• inventory effects; and
• noncontrolling interests.

The exact treatment differs by issuer and mine.

Why investors use it

Total cash cost helps isolate the recurring current-production cost base before the broader sustaining expenditures captured by All-In Sustaining Cost.

If two mines sell gold at similar prices but one has substantially higher cash cost per ounce, that difference can reflect:

• lower Ore Grade;
• lower Metallurgical Recovery Rate;
• higher Strip Ratio;
• higher labor or energy cost;
• unfavorable currency moves; or
• mine-specific royalties and processing charges.

Total cash cost is narrower than AISC

A simplified bridge is:

1Total Cash Cost
2+ Sustaining Capital
3+ Other Sustaining Items
4= All-In Sustaining Cost

Total cash cost can therefore look attractive even when a mine requires heavy sustaining investment.

For that reason, cash cost should not be used as a substitute for AISC or free cash flow.

By-product accounting can materially change the metric

Polymetallic mines may produce copper, silver, zinc, or other metals alongside gold.

Under a by-product basis, revenue from secondary metals may reduce the reported gold cash cost. That can make gold cash cost appear very low or even negative in unusual cases.

A co-product method instead allocates costs across metals.

Neither method is automatically wrong, but comparisons require consistent treatment.

Production versus sales denominator

Some issuers report cost per ounce sold, while others emphasize ounces produced.

Inventory changes can create meaningful differences between those bases. Investors should preserve:

• ounces sold versus produced;
• payable versus contained metal;
• gold versus gold-equivalent ounces; and
• attributable versus consolidated production.

Total cash cost is not a GAAP line item

The metric is reconciled to financial-statement amounts, but it is not a standardized GAAP expense.

Barrick states that total cash costs begin with gold-related cost of sales and remove depreciation, noncontrolling interests, and costs allocated to by-products under its methodology. Other issuers use different bridges.

That makes the reconciliation more informative than the label alone.

Relationship to commodity price

Cash cost is not the same as a mine's break-even gold price.

A mine still has to fund sustaining capital, corporate overhead, taxes, financing, reclamation, and potentially growth investment. A gold price above cash cost does not therefore guarantee positive company free cash flow.

Filing examples

Barrick's 2025 disclosures reconcile cost of sales to total cash cost per ounce and then build from total cash cost to AISC. Dakota Gold's 2025 technical disclosures separately show total operating cost, total cash cost, AISC, and sustaining capital, illustrating the distinction among the layers.

Bottom line

Total cash cost is a narrower current-production unit-cost measure than AISC. It is useful for understanding mine operating economics, but investors should preserve issuer adjustments, by-product treatment, metal basis, and the sales-versus-production denominator before comparing companies.
