We consider the prospect of lightest neutralino ({chi}-tilde{sub 1}{sup 0}) as a dark matter candidate in light of recent interesting observations from the XENON100 and CDMS-II experiments in minimal supergravity framework with large tan{beta} and nonvanishing A{sub 0}. Within the WMAP satisfied zone, there is a large direct detection reach of lighter {chi}-tilde{sub 1}{sup 0} in the lighter Higgs boson mediated resonance annihilation domain of the above scenario. It is seen that the heavier Higgs boson plays a dominating role in the {chi}-tilde{sub 1}{sup 0}-p cross section in the associated zone of parameter space in spite of having a larger mass. Possible LHC signatures are discussed.
