Mines and Mineral Statistics. 
Jamberoo, near Kiama, in the county of Camden. 
Large areas of coal land have been selected by Messrs. Parkes, 
Sutherland, Nichols, Lord, and others, near Jamberoo, and the 
Saddle-back Panges, a few miles from the Kiama Harbour, and 
about 20 miles from Jarvis Bay, the largest sheet of slieltered 
waters in New South Wales. 
Messrs. Parkes, Sutherland, and Nichols, have opened out two 
thick and excellent seams of coal in several places on their land, 
and that adjoining which I examined and reported upon for them 
in January last. The minerals proved to exist here are coal, 
hematite, clay band, and brown hydrated oxide of iron ores, 
and limestone. The uppermost or No. 1 seam of coal near the 
north-eastei'u portion of these selections is 39 feet in thickness, 
and 10 feet 6 inches of the lower part is what I consider to be the 
best and workable portion of it. 
The second is about 21 feet in thickness, the lower 10 feet 
appearing as if it would be the best and workable portion, but 
before this can be accurately ascertained it requires to bo driven 
into, which had not been done when I made my examination. 
The seams of coal vary very mucli in their thickness and character 
in this neighbourhood. 
The iron ores above mentioned exist here in large quantities, 
and some of the specimens of brown hydrated iron ore yield 
51| per cent, of metallic iron. The limestone lies in a thick bed 
below the thick seams of coal before mentioned. 
I haA^e seen no workable seams of coal south of Jarvis Bay, 
and there have been none found up to the present time south 
of these selections. These belong to the upper coal measures, 
and have the usual palaeozoic or lower marine Carboniferous 
fauna underneath in strata lying conformable with them. 
Port Hacking, in the county of Cumberland. 
1,946 acres of land has been leased here and formed into a 
Melbourne Company, with a capital of £100,000, for the purpose 
of boring for coal, and with the expectation of finding it at a 
depth of 200 to 300 feet at Port Hacking, which is about 15 miles 
south of Port Jackson. Two of the Directors called on me a short 
time since to know if I would tell them at what depth I thought 
they would find the first seam of coal likely to be of a workable 
thickness. I replied that instead of 200 to 300 feet, it would be 
most probably be more than 1,000 feet, and in some places on the 
land selected possibly about 1,500 feet, and that if they intended 
to bore they should start with a good-sized borehole, so as to 
enable them to go down at least 1,000 feet.
