The ($d$, $^{3}\mathrm{He}$) reaction on $^{64,66,68,70}\mathrm{Zn}$ was investigated at ${E}_{d}=23.3$ MeV and angular distributions measured for low-lying states. The mass excess of $^{69}\mathrm{Cu}$ is found to be -65.75\ifmmode\pm\else\textpm\fi{}0.01 MeV, about 190 keV less stable than tabulated mass values. A partial level scheme for $^{69}\mathrm{Cu}$ based on the systematics of the ($d$, $^{3}\mathrm{He}$) reaction and the energy levels of the lighter odd mass Cu isotopes is suggested. Spectroscopic factors for proton pickup from the zinc isotopes are also presented.NUCLEAR REACTIONS $^{64,66,68,70}\mathrm{Zn}(d, ^{3}\mathrm{He})$ ${E}_{d}=23.3$ MeV; measured $\ensuremath{\sigma}(\ensuremath{\theta})$, deduced $l$ DWBA analysis. $^{69}\mathrm{Cu}$ mass measured, level scheme suggested.
