  The inclusive reaction $p A \to pK^0_s + X$ was studied at IHEP accelerator
with $70 GeV$ proton beam using SVD-2 detector. Two different samples of
$K^0_s$, statistically independent and belonging to different phase space
regions were used in the analyses and a narrow baryon resonance with the mass
$M=1523\pm 2(stat.)\pm 3(syst.) MeV/c^2$ was observed in both samples of the
data. The statistical significance was estimated to be of $8.0 \sigma$ (392
signal over 1990 background events). Using the part of events reconstructed
with better accuracy the width of resonance was estimated to be $\Gamma < 14
MeV/c^2$ at 95% C.L.
