We study LHC phenomenology of mirage mediation scenario in which anomaly and modulus contributions to soft SUSY breaking terms are comparable to each other. A Monte Carlo study of mirage mediation, with model parameters $alpha=1$,$ M_0=500$ GeV, $n_M=1/2$, $n_H=1$ and $rm{tan}beta=10$, is presented. It is shown that masses of supersymmetric particles can be measured in a model independent way, providing information on SUSY breaking sector. In particular, the mass ratio of gluino to the lightest neutralino for the benchmark scenario is determined to be $1.9 lesssim m_{tildeg}/m_{tildechi_1^0} lesssim 3.1$, well reproducing theoretical input value of $m_{tilde g}/m_{tildechi_1^0} simeq 2.5$ which is quite distinctive from the predictions $m_{tilde g}/m_{tildechi_1^0} gtrsim 6$ of other SUSY scenarios in which gaugino masses are unified at the GUT scale. The model parameters of mirage mediation can be also determined from various kinematic distributions.
