4 ORE BODIES AND ORES. I
<br />The~orea occur in ore shoots in the several veins,
<br />and are principally lead and zino (Galena and Sphalerlte)
<br />carrying values in Gold, Silver and Copper,
<br />The several veins may be best described by enumer-
<br />sting their appearanoa in each oase, as exposed by develop-
<br />ment. '
<br />HILL_ VEIN.
<br />`The Hill vein hoe a atrike,oP about S. 75O east,
<br />average dip about 66° to R, "I„ and average width of 3 Pt,
<br />Vein Pilling oonsists of a brecciated material, carrying lead
<br />and zinc sulphides, vrith some iron and copper pyrites,
<br />Pookets oP the lead and zino oocur in the veln,.aPParding e
<br />smelting produot,
<br />The development an said vein, trill be described.
<br />under mine methods,
<br />GOLD VEIN.
<br />The Gold Vein has a strike oP about N. 6bo E,
<br />average dip about 7b° to the N, W „ and average width oP 3 Pt,
<br />Vein Pilling aonsiete oP a lead sulphide, ooouring in streaks
<br />up to 10 inches in width, and disseminated in a granitio
<br />matrix,
<br />CLIVE VEIN.
<br />Tha Clive vein .has a strike E, and i"1, dips slight-
<br />ly to the N., and has an average width oP ~ Pt, The vein
<br />oonslsts oP a quartzose and Peldspathio material, impreganted
<br />with the lead and zino sulphides, aooompanied by stxeaks oP
<br />Bame,
<br />Said C11ve Lode is developed by a shaft, 4 x B Pt „
<br />"110 Pt. deep, boated N „ 46° E „ about 2000 Pt, Prom Hill
<br />shalt, and a small shaft 30 Pt, deep, boated 'JO Pt, F., oP
<br />main Clive shaft, Sc"mo staging and dxiPting has been Jana
<br />on this vein, the extent of whioh, was lindetoxmined, due to
<br />the preeenoe oP gas in the workings,
<br />A vein is exposed by a pit., about 76 .fit, H, E „ oP
<br />$, 07:ive eha3t, said vein having a strike E, and V!„ dipping
<br />to the N, at an angle oP BOO and having width of 3-1~2 Pt,.
<br />Vein Pilling, ixon stained quartz and feldspar,
