Suggestions for further Development of Gold Mining . 137 
•where the prolongation of this belt might be expected to be, 
and it may be inferred that auriferous deposits are likely to be 
found where Silurian rocks constitute the “ bottom ” beneath the 
great basaltic areas of Warreuheip, Bungaree, and Dean, in the 
vicinity of a lino from Mount Doran to the Hepburn Home 
Paddock. 
Steiglitz, the Moorabool diggings, Mount Kgerton, Gordon, the 
Korweinguboora reefs, and the workings westward of Daylesford 
and thence to near Yandoit, constitute another belt of auriferous 
country along which further discoveries are likely to be made, 
especially in deep alluvial ground southward of Egerton, along the 
Moorabool Valley, and between Gordon and Egerton, where the 
position of deep’ ground has lately been ascertained by means of 
boring with the diamond-drill. 
Next to the eastward is a very important auriferous belt com- 
mencing at the north with Maldon, and extending thence south- 
ward along Sandy Creek, Jim Crow Creek, Daylesford, and thence 
to Blakeville. Further south on the same course payable gold has 
been found near the Ballanee estate and along the Worribee River 
to within a few miles of Bacchus Marsh. The deep alluvial 
ground in the Loddon Valley, near Newstead, may be expected to 
be payable below where it crosses this belt, and towards the 
southern extremity the deep ground of the Ballanee estate is also 
deserving of exploration. 
Castlemnine, Cliewton, and Fryerstown form portion of another 
auriferous zone, the northern continuation of which, beyond the 
granite of the Big Hill Range, is indicated by the gold-workings 
of Myers Creek. 
To the south, Trentham, Newbery, Blue Mountain, Barry’s 
Reef, and Blackwood all lie in the same strike, the southern 
extension being apparently the Lerderderg workings and Good- 
man's Creek, near Bacchus Marsh. 
Raywood, Sebastian, the Whipstick, Eaglehawk, and Sand- 
hurst, north of the granite of the Big Hill Range, and south 
thereof Taradale and Malmsbury, appear to constitute a distinct 
belt, broken in continuity by the granite ; the northern extension 
of this belt may be found under the plains beyond Raywood, and 
the southern beneath the volcanic area around Kyneton. 
In both the Castlemaine and Sandhurst belts there are great 
probabilities of future valuable discoveries in the shape of auri- 
ferous quartz reefs, hotli near the surface and at great depths. 
This closes tho list of the more important and well-marked belts 
of auriferous country where Lower Siiurinn strata form the bed- 
roek.
