?Tlie inspector ¡Of mines at Coolgardie (Mr. S. Cuilingwortli) hajs, under instruct lions, seat the following report to the Minister for. Mines on the leases at Buldania :
"In Accordance with'instructions,: I proceeded to Buldania onl Aprjl 29, 1906. -and made an examination of the?" work- ings wherever possible, and the locality generally,
"Some; 10 or ll leases have at various time«; been applied for and worked to some estent. All aie now abandoned, and the. field-quite deserted. The most promising leases appear to be Buldania Bell,. Ajax, and Excelda, and two-other leases-the Birthday and the Pathway, these two-latter being on tho eastern con-
tinuation of the line of lode from Bul- . dania Bell. Several of the «hafts were unsafe, and the workings below could not be seen or sampled, and the, open cut on the "Klondyke reef was full of
"Several parallel quartz veins have been discovered, separated from each other by from 50ft. to 150ft. of. country. They can be traced through the several leases mentioned ' by occasional outcrop- pings or in. costeens and open cuts. Their strike is approximately E.N.E., and. with the exception of the most northerly vein, the underlay is to the north : in the last-mentioned vein the underlay is
to the south.
" The quartz is.e genreally speaking, very hard, aud oh. the tootAvall sj.de ia mostly frozen on to the country, there being no cleavage or 'dig-" between. As showing iu the surface workings,' the veins aie small, varying in width from 2m. to Sm. ; although at a depth of 40ft. on the Buldania Bell, and again at a depth of fiOft. bu the Excelda, from 18in. to 2ft. of stone is exposed in tho cross- cuts, * ? ' -
''The countrv rock is very hard and flinty, and, although a stratified rock, is very dense, and would bc expensive to work, especially as ft is traversed by. bands of very bard quart-site or quarts porphyry. The last 4ft. or 5ft. of the shaft ou the Buldania Bell, which Mr. Williams proposed to sink to 100ft, is in this material. As the work would have t o be doue by hand labour,.and it is most probable the party would not have an ex- pert drill-sharpeuer among them, ia which case each hole would take a great number of drills, progress would be~slow, and I do not think would average less than ¿3 per f»ot,for sinking; and if tho
shaft continued in the present band or bar of quartzite would cost more. Cross- cutting would not cost less than £2 10$. to ¿3 10s., and might easily cost more. At the least, it would bs an expensive undertaking, and I do .not think the in- dications warrant the expenditure unless the samples sent you are remarkably rich.
" The yields, as *iveu in Air. YPil liains's letter, are high. Tie stone wa* .mostlv taken from surface workings, and evidently picked, and owing to the small size of the veins and the hardness of,the rock would not be payable. Th© stone carries a percentage of mineral, iron pyrites, and arsenical iron pyrites. I did not eec any tellnride, though it
