MANAGERS' REPORTS.

Talisman Dubbo (for period ending May 2). —Talisman No. 2 level: Tlie drive south advanced 26ft, total 677 ft. -The drive is following the lode formation, which contains veins of quartz totalling Cin in width at present of low values. Dubbo level: The rise at 440 ft north was put up 26ft, total 82ft above the level. The rise follows the lode formation, which consists of clay and quartz rubble of low value. Sloping : The following results were obtained this period :—From 240 ft north to 355 ft north, average width 27in, value very good; from 380 ft north to 39ott north, average width 14in, value very S°od , from 045 ft north to 070 ft north, average width 14in, value very good. The exceptionally wet weather experienced this P er greatly interfered with stope workings, tl\e water soaking through from the surface causing the walls of the lode to cave and fail in many places. It has been necessary to procure extra filling in order to keep the slopes closely packed, and also to usei a great many props and stulls to keep the ground from caving. The quartz passes, whlefi are now 150 ft above the Dubbo level, also have required a good deal of attention. The logging of the passes has now worn very thin, and in many places replacements and repairs have been necessary. A crosscut at 415 ft north was uriven from the stopes 15ft into the western wall for the purpose of procuring filling, and also to explore the country for other quartz veins which may exist. Country rock only was disclosed.
