  The methodology of the heterotic mini-landscape attempts to zero in on
phenomenologically viable corners of the string landscape where the effective
low energy theory is the Minimal Supersymmetric Standard Model with localized
grand unification. The gaugino mass pattern is that of mirage-mediation. The
magnitudes of various SM Yukawa couplings point to a picture where scalar soft
SUSY breaking terms are related to the geography of fields in the compactified
dimensions. Higgs fields and third generation scalars extend to the bulk and
occur in split multiplets with TeV scale soft masses. First and second
generation scalars, localized at orbifold fixed points or tori with enhanced
symmetry, occur in complete GUT multiplets and have much larger masses. This
picture can be matched onto the parameter space of generalized mirage
mediation. Naturalness considerations, the requirement of the observed
electroweak symmetry breaking pattern, and LHC bounds on m(gluino) together
limit the gravitino mass to the m_{3/2}~ 5-60 TeV range. The mirage unification
scale is bounded from below with the limit depending on the ratio of squark to
gravitino masses. We show that while natural SUSY in this realization may
escape detection even at the high luminosity LHC, the high energy LHC with
\sqrt{s}=33 TeV could unequivocally confirm or exclude this scenario. It should
be possible to detect the expected light higgsinos at the ILC if these are
kinematically accessible, and possibly also discriminate the expected
compression of gaugino masses in the natural mini-landscape picture from the
mass pattern expected in models with gaugino mass unification. The thermal WIMP
signal should be accessible via direct detection searches at the multi-ton
noble liquid detectors such as Xenon-nT or LZ.
