Physical properties were derived for the candidate open cluster La Serena 94,recently unveiled by the VVV collaboration. Thanks to the exquisite angularresolution provided by GeMS/GSAOI, we could characterize this system in detail,for the first time, with deep photometry in JHK$_{s}$ - bands. DecontaminatedJHK$_{s}$ diagrams reach about 5 mag below the cluster turnoff in H. The locusof red clump giants in the colour - colour diagram, together with an extinctionlaw, was used to obtain an average extinction of $A_V =14.18 \pm 0.71$. Thesame stars were considered as standard - candles to derive the clusterdistance, $8.5 \pm 1.0$ kpc. Isochrones were matched to the cluster colour -magnitude diagrams to determine its age, $\log{t(yr)}=9.12\pm 0.06$, andmetallicity, $Z=0.02\pm0.01$. A core radius of $r_{c}=0.51\pm 0.04$ pc wasfound by fitting King models to the radial density profile. By adding up thevisible stellar mass to an extrapolated mass function, the cluster mass wasestimated as $M=(2.65\pm0.57) \times 10^3$ M$_{\odot}$, consistent with anintegrated magnitude of $M_{K}=-5.82\pm0.16$ and a tidal radius of$r_{t}=17.2\pm2.1$ pc. The overall characteristics of La Serena 94 confirm thatit is an old open cluster located in the Crux spiral arm towards the fourthGalactic quadrant and distant $7.30\pm 0.49$ kpc from the Galactic centre. Thecluster distorted structure, mass segregation and age indicate that it is adynamically evolved stellar system.
