For the vortex lattice in an anisotropic superconductor with well-separated cores (Hci <C ÷ <C îÓÇ) it is shown that sizeable de Haas-van Alphen oscillations are caused by the levels crossing of the energy threshold separating localized and extended states of excitations moving in the average magnetic field, B.
