“ Along witli tlie tin in tlie wasli there were a few topazes and a little magnetite. 
“ The washdirt rests directly ujion an uneven surface of granite. A section of 
this is well seen in a claim, originally part of the old P.C., viz. : — 
(a) Stratified gritty sand, of a yellowish red colour, with a somewhat gravelly 
base, and varying in thickness from 10 to 14 feet. 
(5) Cement, the matrix being a clay of a bluish-white colour, though often 
stained yellow. Of this there are from 3 to 4 feet. 
It is in this cement, wdiich contains boulders of rocks of the same nature as that forming 
the surrounding country, that the cassiterite occurs in irregular patches. A small 
quantity of tin, hut of no commercial importance, is met with in the upper stratified 
sand. It is a noteworthy circumstance that the ground to the south of Prospectors’ 
Creek contains a fair quantity of tin in the surface debris, but, as yet, search has failed 
to discover the lode from which the tin crystals undoubtedly came. 
“ There are reefs and dykes from which tin has been derived, scattered over a 
fairly wide extent of country ; but upon none of them has any great amount of work 
been done uj) to the present. Some of the dykes bear a marked resemblance to those in 
the Western and Coolgarra districts. 
“ These dykes are intrusive basic igneous rocks. So far as is at present known, 
these do not attain any very great thickness, nor does their horizontal extension appear 
in this district to be very great. 
“ Two leases have been taken uj) — the 40-acre lease, and the 60-acre lease ; these 
arc situated about S to 9 miles east from Kangaroo Hills Station. 
“ In the 40-acre lease, situated on the eastern bank of the gully, a tributary of 
the Douglas, a cutting has been put in on the face of the hill upon a tin-bearing lode in 
granite country, which appears to trend north-east and south-west. A section across 
this lode shows on the north about 30 inches of gangue made u]) of quartz and chlorite, 
with the binoxide of tin disseminated through it. Small quantities of the blue and 
green carbonates of copper are also contained in the gangue. Adjoining this to the south 
there is a thickness of about 30 inches of quartz. A thin film of serpentine separates 
the quartz from the gangue. 
“ A few yards up the hill another cutting has been put in with the object of 
following a vein running N. 65° E. The matrix of the vein is similar to that above 
described. 
“ Near the head of the gully an open work shows a wedge-shaped mass of quartz 
and chlorite trending due east. Both walls are granite, the faces of which are often 
coated with the green carbonate of copper. Some very large crystals of cassiterite 
could be seen in the quartz lying near the surface. 
“ Still further up the creek a shallow shaft has been sunk upon a vein which has 
a course of K. 30° E. The vein has a thickness of from 1 to 12 inches. Ilsematite, 
limonite, and iron pyrites occur associated with the quai’tz and tin. 
“ The 60-acre lease lies some distance west of the last. Upon it a shaft has 
been sunk to a depth unknown to my informant. 
“ In the shaft a leader with a general course of north-east and south-west is 
met with. 
“ Where the shaft now stands a good bunch of tin-bearing gangue, about 2 feet 
6 inches across, has boon met with. The gangue is quartzose chlorite of a nature 
similar to that met with throughout the district. 
“West of the shaft an open work shows a good leader of variable thickness 
underlying to the north and trending east and west. The open work, 20 feet in depth 
and now full of water, is reputed to have yielded a fair quantity of tin ore.
