Crown Lands and allotment i4 A ; the Federation, allotment 6; the Just in 
Time, allotment 5 ; the Nick 0 ; Time, allotment 3. The above leads and 
reefs, with the exception of the Poseidon Lead, have been reported on by 
Mr. S. B. Hunter in Bulletin, Geological Survey, No. 17, 1905. 
The lead will continue on through Lee’s allotment 9, and will re-cross 
the Woolshed belt, where an enrichment should occur in the wash. 
The lead will then continue on, bearing a little more to the north-east, 
and out through the 85-ft. ground proved by boring just below the north¬ 
west comer of allotment 8, parish of Tarnagulla. It should then junction 
somewhere in allotment 7 with the deeper run of ground proved in the 
Race-course Reserve, 139 feet deep, and then continue on towards New¬ 
bridge. (See Annual Report, 1905.) 
Mr. Hunter has kindly supplied me with the boring records near the 
Reserve, thus enabling me to show the position of the deep ground. 
Finally I may state, that at the time of my visit, the Poisedon field was 
well manned, and all the alluvial of value close to the rush had been 
pegged out. 
Witliout doubt there is much of the country in the district which should 
be well prospected and which is sure to receive some attention from the 
miners who have not been able to obtain claims close to the rich finds at 
Poseidon and are now commencing to prospect to the north and south of 
the rush. 
I must thank Messrs. Williams and Yeo> and the many claim-holders at 
Poseidon for the assistance given to me in obtaining the records, positions, 
and details of the nuggets found on the field. 
Nuggets at Ironbark Gully. 
The accompanying plan shows some of the geological features near the 
head of Ironbark Gully, about three-quarters of a mile south of the post- 
office, Tarnagulla, and the site of the Magnum Bonum nugget dis¬ 
covered on 16th July, 1889. Prior to the rich Poseidon discoveries, this 
was the largest nugget found near Tarnagulla. 
The Magnum Bonum nugget (458 oz. gross weight) was discovered in 
rea iron-stained gravel at a depth of 4 ft. 6 in. in Ironbark Gully, opposite 
a small tributary gully named Tormie’s. Mr. Smith, son of the discoverer 
of the Magnum Bonum, showed me the old shaft and enabled me to locate 
the site on my plan, at a point in Ironbark Gully nearly midway between 
the western reef and the Greeks Hill reefs on the east. (Site No. 1.) 
In Ironbark Gully it was nugget or nothing, the fine gold only yielding 
about 2 grains to the tub. 
The next in size to the Magnum Bonum was one weighing 15 lbs. 
(180 ozs.) found by a Welshman in 1859. 
Another nugget worthy of note was found by Dunk and Hardy just 
below the Magnum Bonum. Its gross weight was 9 lbs. (108 ozs.) (Site 
No, 2.) 
Ironbark Gully runs nearly east and west across the Ordovician slates 
and sandstones, and has its outlet to the east. 
On the hill to the north I found a basic dyke 3 feet wide, running 
nearly north and south. It crosses Ironbark Gully, and nuggets have been 
found on both sides of it. 
A reef known as the Cross reef, which yielded ij ozs. to the ton, was 
worked right to the dyke, and their relation to< each other is shown by the 
presence of crystals of soda-lime felspar in the Cross reef.
