The main works site was established in a sweeping bend on the south bank of the Wolgan River and extending up the adjacent talus hillside. These works consisted of retorts, various distillation areas, oil storage tanks and washers, plant for the refining of the various finished products, a power station, workshops, etc., with provision for future expansion. They were built in a substantial manner, as attested by the extensive ruins that stand to this day. Although construction commenced in 1906, it was not until 1911 that the initial stage was completed and the retorts charged for the first time.
