There are no x marks the spot locations, any area that the old timers were prospecting in will give you a chance to pick up something, as a "general' rule the ground will be shallower" on the sides of hills/gullies, the bottom areas usually have more material washed down (silt/leaf litter build-up) so generally the gold will be a bit deeper.

Leaching process for recovering valuable metals from the LiNi1/3Co1 ...

Although the valences of Li and Ni do not change during the leaching process, their leaching efficiencies were also promoted because all the metals are present in the same oxide, LiNi 1/3 Co 1/3 Mn 1/3 O 2 (Li et al., 2010). With a further increase in the H 2 O 2 concentration to 1 vol%, the leaching efficiencies for all the metals reached 99.7%.
