Sediment-hosted, very fine-grained gold deposits, characteristic of Nevada and responsible for a large share of US production.
A sediment-hosted disseminated gold deposit type named after the Carlin Trend in Nevada. These deposits contain microscopic gold in altered sedimentary rocks and are processed by heap leaching or roasting.
Carlin gold is invisible to the eye and often refractory, so metallurgy matters as much as grade. Nevada's endowment and permitting regime make the style disproportionately important to North American juniors.
