1882 Frank Long discovered Silver-Lead at New Mt Zeehan Mine
1883 to 1912 most major deposits discovered
Intense mining activity to 1912, many mines closed by 1914
Production 1890 – 1919 262,883t of Silver-Lead ore
Tribute mining in old workings continued until 1960’s
Post WW2 minor production from New Montana-Zeehan Western until 1958and Oceana until 1960
Tin-copper production from Oonah Mine (15-20,000t) 1897 - 1910
Minor cassiterite noted at Queen Hill 1937

Placer then Gippsland commenced Modern Exploration in the mid 1960’s
Queen Hill Tin Deposits first Intersected in 1971.
Aberfoyle – Gippsland JV saw intensive exploration until 1992.
RL5/1997 acquired by Stellar Resources and commenced exploration in 2010
PFS completed July 2013.
