Located approximately 1km N of Flaggy Creek, and approx. 67 east of Albury.
First records of this deposit has 0.45 ton of concentrates being obtained in 1919.
Serious mining at the Womobi Mine occurred from 1939 to 1943 and produced tungsten-bearing ore. Molybdenum was produced as a by-product. The host rocks are quartz reefs and veins within the Lower Devonian Thologolong medium-grained grey biotite granite. The reefs/veins occupy a series of straight fractures which strike at about 80 degrees east of north. Three main orebodies were worked. The East orebody which was about 150 feet in length and averaged 14 inches in width. The middle orebody was 110-165 feet long and averaged 16-18 inches in width. The West orebody was only 45 feet in length and averaged 18 inches in width. Although mined for a few years it was never profitable.
The mine gets its name from the first two letters of the mineral names: wolfram, molybdenum and bismuth.
The following additional minerals have been noted in the 1945 report but no specimens are know to confirm- cassiterite, chlorite, amblygonite, powellite, sphalerite, galena and tetrahedrite.
19 valid minerals. 1 erroneous literature entry.
