“At the time I visited Donnybrook, in June of 1890, Mr. Moss was the only one 
in the field. Little or no work could be said to have been done ; hence to examine the 
surface features was all that could be done. The deposit occurs amongst a series of 
quartzites and saccharine limestones, the age of which, in the absence of detailed 
mapping or fossil evidence, I would hesitate to fix. Erom such an examination as was 
made, the limestones did not appear to occupy any very great extent of country, and 
the whole of the rocks appeared to have undergone a certain amount of faulting and 
disturbance, resulting in the production of fissures of variable dimensions in which the 
ores were deposited. 
“ About half-a-mile north of the camp at Donnybrook a shaft has been put down 
to no great depth upon a lode of galena of variable thickness. The hanging-wall is 
well-defined, while the foot-wall cannot be said to have yet been found. A greyish- 
blue limestone forms the hanging-wall. The course of the lode appears to be about 
N. 20° E. In the cap were a little green and blue carbonate of copper and cerussite, 
with kernels of galena. The lead is said to assay about 5J oz. of silver to the ton. 
“ A little to the north a similar galena lode had been opened up ; this is said to 
assay 20 oz. of silver to the ton. Yery little wmrk had been done at the time of my 
visit. The ore at the surface contains green and blue carbonates of copper, galena, and 
carbonate of lead. One of the walls is a white saccharine limestone which runs 
N. 65° E. 
“ Close to Donnybrook, the most work appears to have been done upon a lode 
known as the Hidden Treasure. A shaft has been put down to a depth of 40 feet. Ho 
foot-wall appeared to have yet been met with. 
“ The lode consisted of a large body of kaolin and lithomarge, containing 
small quantities of green carbonate of copper, some showing native silver fairly 
abundairtly, and a little oxide of manganese (hausmannite ?). A specimen from 
the surface, containing cerussite and copper carbonates, assayed for me by Messrs. 
Coano and Clarke, yielded 314 oz. 5 dwt. 1 gr. of silver to the ton and 19 per cent, 
of lead. 
“ At the foot of the shaft galena was beginning to make its appearance at 45° 
to S. 60° E. The galena, of fairly fine grain, yielded, on assay by Messrs. Coane and 
Clarke, 1 oz. 9 dwt. 9 gr. of silver to the ton and 28 per cent, of lead, with a trace of 
gold.” 
Since Mr. Maitland’s report was written it appears that the Euuning Creek 
Silver Mines are about to become of considerable importance.

ANNAN AND BLOOMFIELD TIN FIELDS. 
These tinfields are comparatively new, and till very recently the only ore 
exported has been stream tin, which is found in narrow gullies among tropical jungle. 
Eortunately water is abundant, and washing presents no difficulties. The narrowness 
of the gullies hitherto worked has made it not worth while to applj' hydraulic power to 
the washing, but this will probably be done in future in the wider and deeper drifts of
