Wolframite.

Named Cosmopolitan by (Marshall, 1918), this may also be a gold deposit, and separate from the wolframite lode.

The lode is on both sides of Lammerlaw Creek, one mile south of Battery Creek.

In March 1917, Rodgers and party discovered the vein, which tested at 39% tungstic oxide. Hand picked pieces can be up to 60% WO3. There are two other small lodes 300 yards to the south. (Marshall, 1918) dismissed the prospect as the surface samples were very poor in wolframite. It appears the lode is near the Cosmopolitan gold mine, although little information could be found on this either, other than a tunnel and shaft in 1883. No further information was found on the wolframite, and may have never ventured further than surface pottering.

Mindat co-ordinates are approximate.
