The intermediate level in the Havillah mine could also be pushed out 
to the west, and by this means a mile in length of the lead would soon 
be available for panelling. 
If the north-west extension of the bottom level were made from the 
Charlotte Plains shaft, as previously proposed, it would be the means 
of cutting off the water in that direction ; and if the Havillah west inter¬ 
mediate were driven right across the gutter it would tap the water in that 
part of the mine. 
The present cost of pumping at the Charlotte Plains is .£125 ns. 5d. 
per week (average of 28 weeks); at the New Havillah, £89 os. 6d. per 
weeK; total £214 11s. nd. per week. 
The time required to get the block of washdirt 400 feet square ready 
for panelling would be probably from three to four months, and if the 
main west bottom level is extended and the Havillah intermediate level 
extended during that period, the future working of the mine would be 
greatly facilitated. 
The pumping charges would be, say, £3,300 for four months, and 
allowing the other costs and charges for preparing the 400-ft. block to 
be £3,400, and a further sum of £3,300 for extending the main and 
intermediate levels, a sum of £10.000 would be required, and this should 
suffice to place the mine in a self-supporting position, if the ground in the 
400-ft. block proves of as good value as the last ground panelled. 
It is proposed to form a company, and if this is done and half the 
above amount raised to continue operations, I recommend that assistance 
to the extent of the other half should be granted, for the plant is excep¬ 
tionally good, the prospects of the mine, as the main gutter is opened 
up, are most encouraging, and the mine is in thorough working order, so 
that the washdirt could be effectively dealt with as soon as it is found to 
be profitable.

THE NEW HAVILLAH AND CHARLOTTE PLAINS MINES, 
LODDON VALLEY, NEAR MOOLORT. 
By E. J. Dunn. F.G.S., Director , Geological Survey. 
New Havillah Mine. 
I he collar of the shaft at this mine is 723 feet above sea-level, and 
the plat of the main reef-level is 372 feet above sea-level. 
The main reef-level runs out 1,235 feet north-westerly from the shaft, 
and it is 51 feet below the bottom of the lowest floor of the wash-dirt now 
being worked. An intermediate level connected with the main level by a 
jump-up has been extended for nearly 1,000 feet still further to the north¬ 
west. _ This intermediate level is 17 feet below the lowest point of the 
wash in the present workings. A wash-dirt level has been pushed out 365 * 
feet still further north-west. Near the end of this drive the wash-dirt is 
2 ft. 6 in. thick; it is very wet, and is rapidly dipping underfoot in a 
uoith-v esterly direction. Shafts over 4 feet deep had to be sunk in the 
floor of the level to reach the bedrock, and nearly all the water in this 
mine bubbles up from this most north-westerly wash-dirt drive, suggesting 
tuat the main gutter is in this direction but still further north-west. The 
v ash-dirt ma.y be on the outer edge of the main gutter.
