  In chiral crystals crystalline symmetries can protect multifold fermions,
pseudo-relativistic masless quasiparticles that have no high-energy
counterparts. Their realization in transition metal monosilicides has
exemplified their intriguing physical properties, such as long Fermi arc
surface states and unusual optical responses. Recent experimental studies on
amorphous transition metal monosilicides suggest that topological properties
may survive beyond crystals, even though theoretical evidence is lacking.
Motivated by these findings, we theoretically study a tight-binding model of
amorphous transition metal monosilicides. We find that topological properties
of multifold fermions survive in the presence of structural disorder that
converts the semimetal into a diffusive metal. We characterize this topological
diffusive metal phase with the spectral localizer, a real-space topological
indicator that we show can signal multifold fermions. Our findings showcase how
topological properties can survive in disordered metals, and how they can be
uncovered using the spectral localizer.
