  A primordial black hole (PBH) is thought to be made of the regular matter or
ordinary mass ($M$) only, and hence could have already been decayed due to the
Hawking radiation if its initial ordinary mass were $\lesssim 5 \times 10^{11}$
kg. Here, we study the role of gravitomagnetic monopole for the evaporation of
PBHs, and propose that the lower energy PBHs (equivalent to ordinary mass $M <<
5\times 10^{11}$ kg) could still exist in our present Universe, if it has
gravitomagnetic monopole. If a PBH was initially made of both regular matter
and gravitomagnetic monopole, the regular matter could decay away due to the
Hawking radiation. The remnant gravitomagnetic monopole might not entirely
decay, which could still be found as a PBH in the form of the pseudo
`mass-energy'. If a PBH with $M \gtrsim 5 \times 10^{11}$ kg is detected, one
may not be able to conclude if it has gravitomagnetic monopole. But, a
plausible detection of a relatively low energy (equivalent to $2.176 \times
10^{-8}$ kg $< M \lesssim 5\times10^{11}$ kg) PBH in future may imply the
existence of a gravitomagnetic monopole PBH, which may or may not contain the
ordinary mass.
