Besides these yields there were 7 tons 7 cwt. of pyrites concentrated, 
which were sold for £3 3s. 6d. per ton (£23 6s. 8d.). The battery 
sand was sold to a private cyanider for Is. 9d. per ton, with an 
additional charge of 3d. for steam, making 2s. per ton. 
Stoping has been carried on continuously since the new company 
took charge, and only 50 ft. of additional driving was done—this at 
the 1^0. 8 level south along the break.

OUTCROP OF COAL UEAR FOSTER. 
By S. B. Hunter, Engineer for Boring. 
A coal outcrop is situated close to the north boundary, and about 
20 chains eastward from the north-west corner of allotment 22 b^ sec¬ 
tion C, parish of Wonga Wonga South. Where tested by a small 
tunnel, the coal is somewhat faulted, and consequently soft, through 
crushing. The quality appears to be excellent, and an analysis made 
some time ago by this Department of a sample forwarded by Mr. 
Baker, the discoverer, proved it to be high in fixed carbon and low in 
ash percentages. 
Mr. Baker informed me that about 30 ft. to the west of the out¬ 
crop he sank a hand bore, and proved nearly 5 ft. of coal. A Govern¬ 
ment bore sunk in 1896, three-quarters of a mile away, in a north¬ 
easterly direction^ proved 5 in. of coal at 474 ft. and 1 ft. 10 in. of 
coal at 750 ft. deep. It is probable that the 1-ft. 10-in. seam is a 
continuation of the seam on the dip, although the depth (750 ft.) 
indicates that faulting down, in addition to the natural dip of the 
strata,, has occurred.

TYRELUS REEF, BLACK RAKGE, EDI. 
By A. M. Iloiuitt, Field Geologist. 
Tyrell’s gold mine is situated in the parish of Edi, county of Dela- 
tite. on the top of a steep ridge in the Black Range country, about 4^ 
miles in a direct line to the east of Whitfield tovmship. 
The containing strata are predominant sandstones and occasional 
dark-grey to blue slates, dipping from 60° to 70° west, and striking 
K. 35° W. These strata are of Upper Ordovician age, and show con¬ 
tact metamorphism along the course of an extensive mica-diorite dyke, 
associated with which are the auriferous quartz veins.
