Ithe tunnel. It parallels the Japan and is about 140 feat~froa it. This vein <br />;main cut in the drift mentioned on the Cross vain. At point of intersection <br />e orouad uas tiscbered and could not be examined. On the north-west side of <br />i <br />ift the vein is comparable to the vein cut in main tunnel, except that it is a <br />the Tides. Gr_ the south-went side of drift t?:e vein exceeds two feet in width <br />r 7 ws been drifted on some QUO feet. i1:e vie:, annexed s?:ows a stone just opened <br />st'r.i~ vein. Ao driftiz~ proceeds to the eouth-east this vein appears to be <br />•adually getting wider, and I was ini'ormed that the values in gold had increased <br />;r'.' msaeriaily in the 1^~.:.t 1GG feet cf driftiz~5. /s near as could be ascertained <br />sere i?:e Cross weir. cute tk.c torr_ing them was no faulting whatever, but I wan <br />~.ble to deierc~ine en account of timbers whetl:=r the Cross vein cut the iiarning <br />r the ilarnirq; the Cross vein. <br />Comparable to the idorning, #b'~?~r~outh-east of tl:e Cross vein on <br />he Jaaaz: the vein•:is: such larger. Tl;e values are reported somewhat loner lrut the <br />d <br />g;regate asount of ore yields larger returns. <br />Un the north-west end of the workings on t)3e Japan veir_ .:+, the tunnel <br />evel, the vein pinches down to a mere ~•eak and appears to have been faulted. A <br />series of s:~a.ll parallel 1'iasurea all filled with ores or so-called blind leads, <br />leave.what is developed as the vein at acute angles. ''hie same condition was <br />somee;hat :,oticeable before the Cross vein woo reached by Japan drift. On outface <br />_~id about where the "blind leads" occur i.n the nartYwreat drift there is apparant- <br />ly another vein crossing that is roughly parallel to the Cross veiny and tkre Jap- <br />an croppizas are seeu~ingly faulted some 30 or 4U feet. Owing to elide rock tPsia <br />could not be ac~szrutely determined. The conditions as a whole however, are such <br />as to justify a cross-cut drift up the hill from the rwrth-west erui of Japan tun- <br />nel level for a distance of 40 or b0 feet and to expect a recovery of ore body. <br />i <br />1 <br /> ~, <br /> i <br />I <br />~ '~ <br />j <br />I <br />, <br /> <br /> j, <br /> y <br /> 1 <br />i <br />I, <br />~4 <br /> <br />~? r <br />r: <br />~ ~: <br /> <br />j <br /> <br />
