ya,i too think so.
but,another factor dat the relative solubility of Ag and Au is too high than solubility of other 2 metals , as Ag and Au are soluble forming soluble complexes wid aqua regia.

Atomic chlorine forms metallic chloride with gold.
Au + 3[Cl]^- â†’ AuCl₃
Metallic chloride then reacts with HCl to produce hydrometallic chloride.
AuCl₃ + HCl â†’ H⁺[AuCl₄]^-
Hydrometallic chloride is soluble in aqua regia.
