Few mining men in this State know that in the Barraba district there exists an enormous copper belt, sections of which are adding considerably to the copper production of this State The chief mine in the belt is the Gulf Creek, Limited, but there are others which show most favourable prospects from the little work that has been done upon them. Mr W H. Trewenack, who is developing and equipping the Gulf Creek mine, has within the last two years aroused considerable interest in the district in mining circles, and to him may be given the credit of reopening a mine which had previously een refused by expert representatives of   the miing industry.SUCESSl has attended Mr.   Trewenack's efforts on every, band, and upon a close examination of the Gulf Creek mine I am able to state that it looks like turning out one of the big copper producers of the coloy., The cupriferous belt, it may be stated, continues practically in a north and south line for many miles in fact from Gulf Creek to a point some miles norteast of Bingara .A lengthy report of the Gulf Creek mine appeared in the " Sydney Mail " recently
