Zero-field experiments have been carried out on a series of polycrystalline U_{1-x}Th_{x}Pt_{3} (0 <= x <= 0.05) samples in the temperature range 0.04 - 10 K. At low Th content (x <= 0.002) magnetic ordering on the time scale of the uSR experiment (10^{-8} s) is not detected. For x = 0.005 a weak magnetic signal appears below T = 2 K, while for 0.006 <= x <= 0.05, spontaneous oscillations in the uSR spectra signal the presence of the LMAF phase.
