Regarding Scarlett:

"4.3.5 Scarlett’s Black Coal Mine at Berry’s Creek
Map Reference: 8121-3-2 Mirboo 221.485

On Berry’s Creek, about 4.5 kilometres south west of Mirboo
North, an outcrop of black coal was found in 1889 and was
known as Scarlett’s Seam. Eight deep bores were sunk by
the Mines Department from 1888 to 1890. In bore Number
Six, several thin black coal seams merged resulting in a four feet six inches thick seam.

The geological assessment was that the drilling ‘clearly showed that Scarlett’s Seam extends over a considerable of ground, though evidently much faulted in places.’

To 1930, about 2,000 tons of black coal was extracted from
a shaft but the mine proved uneconomic compared to the
Wonthaggi and Korumburra area mines, largely due to the
comparative transport disadvantages.

In 1957, the mine was reactivated on Scarlett’s Seam at
Berry’s Creek; the adjacent creek was bridged and mining
recommenced by a new drive into the seam.

In 1958, an underground survey of the workings was carried out by the Mines Department. The mine was referred to as the Mirboo Coal Mine Berry Creek in the Mines Department
Annual Report for 1958, but as Berry’s Creek Coal Mine, Mirboo North in the Annual Reports for 1957 and 1959. At 1959, this mine was the only black coal mine in operation in Central Gippsland."
