lode is strongly marked, and 5 feet thick, and carries good copper ore. 
The lode continues southward and appears to be a little east of the very 
prominent pinnacle of rocks. Grano-diorite rocks crop out near the present 
camp in the creek bed, so that it evidently underlies the Heathcotian beds, 
and the lode may be found in the granite by sinking, for this rock is 
favorable to the lodes.

Sketch Plan of Copper Lode at Accommodation Creek. 
The copper lode in this locality has a promising aspect and is well 
worth opening up, especially with copper at over ^100 per ton. In testing 
such lodes as this every effort should be bent towards opening the lode below 
water-level. Atmospheric action and leaching has gone on to such an 
extent along the upper portions of the lodes, that there is no possibility of 
arriving at its original value except by sinking into the lodes below 
water-level and driving on them. In this case every effort 
should be made to get a shaft* or winze down to' test the lode in its 
original condition. In too many cases the money that should be devoted 
to testing the lode where it has not been impoverished by surface action is 
frittered away in shallow surface trenches and pits, and nothing but dis¬ 
appointment results. The indications here fully warrant the expenditure 
necessary for testing the lode to a depth of 100 feet below the creek level. 
It is to be expected that many other copper lodes would be found by 
prospecting the surrounding country. Both the Heathcotian beds and the 
grano-diorite are favorable to the occurrence of silver-lead and copper 
lodes. There is a permanent and considerable supply of water in Jingallala 
Greek at a distance of about 4 miles from the present workings. The 
transport difficulty is a serious one, but as the country becomes opened up 
by railways this will be solved, and even now 20 per cent, ore would be 
profitable to work, and by concentrating the ore could be brought up to 
this standard if the quantity is sufficient to warrant the erection of plant.
