The species listed against this site is based on the first reference (Economic Geology 1997 V92 pp181-209). This article relates to the nearby Nevoria Mine. There is no guarantee both locations share the same species, and is possibly inaccurate for the Marvel Loch Mine.

The Marvel Loch Mine is on the outskirts of the small gold mining town of the same name, 35 kilometres south south-east of Southern Cross. It is named after a horse who won the Caulfield Cup in 1905.

At the Marvel Loch Mine the ore is found in steeply plunging flattened shoots, within a regional shear system in the Southern Cross Greenstone Belt. It is in a meta-pelite unit sandwiched between magnesium rich amphibolite, fine grained komatiite and banded iron formations. The shear which hosts the ore-body has a five kilometre strike, 80-100 metres wide, and is 1 kilometre west of the Ghooli Granite Dome contact.

Mineralisation occurs as disseminated sulphide lode systems as steeply southerly plunging pods with meta-pelite and associated biotite-carbonate-pyrite alteration. Or it is found as quartz-sulphide veins along the upper contact of the meta-pelite, associated with carbonate-diopside alteration. The principal ore is arsenopyrite-pyrite-gold. Other sulphides found include scheelite, pyrrhotite, and lesser galena, sphalerite and argentite.

Mining as the Marvel Loch Mine started around 1905, but it needs to be noted in later years the modern mine gobbled up several nearby leases which went under different names. Newspaper reports were scathing about the mine management back in Melbourne of the Marvel Loch Gold Mining Company, claiming a bank account had not been opened in the company name and the books were out of order. In 1911, a director, Frances Newport was charged with embezzling money. Several directors subsequently resigned. In 1912, after a visit by one of the directors, the mine manager was forced to resign and thirty workers sacked. The director described the operation in words that amounted to a holiday camp.

Soon after the mine was let out to tributors who actively worked it till 1915. An influx of water, and an accident where one miner was killed hampered their operations. A request for fortfeiture of the lease was made through the Warden's Court and the mine was reported abandoned in 1918. In 1920, the plant was sold to the nearby Golden Butterfly Mine.

In 1933 it was reported local prospectors were trying to re-open the mine. In 1935, the Marvel Loch Gold Development NL was floated to purchase the leases from the Great Western Development Company. These were the Brands, Firelight, Exhibition and Lubra Mines 1 kilometre north of the Marvel Loch Mine. These were later incorporated into the modern mine. A new plant was erected and development work done employing 100 men. This however did not last long as by 1938 the mine had not lived up to expectations and the company was in receivership.

A local syndicate in 1949 had pegged the old Marvel Loch Mine lease and were doing exploratory work on the Firelight leases.

Between 1905-1986 the mine produced 136 300 oz of gold. From 1979-1987 the
mine re-opened as a joint venture between Kia Ore Gold Corp NL and Western United Limited. The lease was then sold to Mawson Pacific Limited, and then Sons of Gwalia Limited who re-opened the mine as an open pit in the 1990's. A new processing facility was constructed in 2001. The company suffered a financial collapse in 2004, in part from unauthorised foreign exchange dealings by its financial officer losing $190 million (Australian), and from its purchase of several mines at inflated prices. The company folded and the Marvel Loch Mine was sold at a bargain basement price to St Barbara Limited in 2005.

St Barbara Limited came to a position where it owned most of the mines in the district, and some where mined, all the ore processed at its Marvel Loch plant. These mines gradually closed until only Marvel Loch remained in operation. The open pit closed in 2009. Underground operations accessed the New, Sherwood and Undaunted Lodes in the northern section of its lease. This decreased to part-time processing, and eventually the mine closed late 2012. In January 2013 it announced it was selling its Southern Cross leases to the Chinese company Hanking Gold Mining.
