The La Plata property is hosted by a sequence of predominantly basaltic to andesitic volcanic and volcano-clastic rocks constituting the Eocene portion of the Macuchi Unit in the western flank of the Cordillera Occidental.

The mineralization encountered at La Plata is characterized as a gold-rich polymetallic VMS Noranda/Kuroko-type deposit. The mineralization occurs as lenses of pyrite, chalcopyrite and sphalerite with minor bornite, galena, tennantite, chalcocite, covellite and native gold in a gangue of quartz, sericite, and barite.

The La Plata VMS deposit comprises of the La Mina South block, and the La Mina North block, both striking in a north-south orientation. The La Mina South block and the La Mina North block are separated by a late sub-vertical fault zone.

The volcanic and sedimentary sequence in the central and northern part of the La Mina blocks have been intruded by at least two different stages of late dykes, the coarse-grained rhyodacite and the fine to medium grained pyroxene-phyrric gabbro dykes.

In addition to the mineralization known at the La Mina deposit, at least 14 other key exploration targets have been identified along a 6-km trend of the La Plata favorable stratigraphy.
