    • Nevada's Micron Gold Deposits from the Carlin trend The microscopic lead in these deposits is ideal for recovery by cyanide leaching. The small particle size means the precious metals are easier to dissolve. Its tiny size also explains why the old timers never found these deposits as their principal means of exploration was the lead pan.
