The last ten years have seen a resurgence of interest in exotic spectroscopy driven by the discovery of the X(3872) in the J/ψππ spectrum. Searches and studies of exotic quarkonia form an important part of LHCb's physics programme. We present results for the production of ψ(2S) and χc(1,2) in the dimuon plus pions or photon channels, as well as the first results for X(3872) production using the dataset collected in 2010, which corresponds to about 34 pb–1. A measurement of the X(3872) mass in the J/ψππ mode together with production properties will be presented. The ψ(2S) production in the same decay channel and the χc2/χc1 cross-section ratio will also be discussed, together with future prospects on these measurements at LHCb.
