ANALYSIS OF GREGORY-IRWIN COAL.
Messrs. H. R. Watson & Co. recently forwarded a small parcel of coal from
the Gregory Irwin C.M. Company's area to Mr. H. R. Harland, of Plough-
court, London, for assay, and have since received from that gentleman, the
following report :-
CERTIFICATE OF ANALYSIS.
SAMPLES OF COAL.
I certify that the following are the results of the analysis of the above
sample:-
Reference 7576, sample of coal marked Australia.
Steam coal for
boilers.
Water 17.04 p.c. 4.62 p.c.
Volatile matter 28.61 ,, 27.24 ,,
Ash 13.06 ,, 9.18 ,,
Fixed Carbon 41.29 ,, 58.96 ,,
100.00 100.00
The proportion of water in this coal is rather high, the ash is also
higher than is present in good coal, but this is not surprising
considering the sample is from the surface. The fixed carbon is low, and
the coal will not form coke.
R. H. HARLAND,
Assayer,
37, Plough Court, London, E.C.
Mr Harland adds: "For surface coal I regard the assay as very encouraging,
especially as to the percentage of ash, since very little of the Newcastle
(N.S.W.) coal contains less than 10 percent of ash, and what is known as
Southern coal (Wollongong district) averages about 12 percent ash. It
would be good coal for furnaces and electric lighting purposes." He
suggests that a bore lower down should be made, to prove what kind of coal
is below.
