partially emlieddi-d, and over a widlli of from 12 to 18 foot in parts, to 
as much as even 50 or 00 feet in another. 
The thickness of the deposit below tlio stirfacc Juis not been 
fully ascertained ; but a shaft has been put clown in tlie lode itself to a 
depth of 43 feet, and at the bottom a loved was driven which ])roved it 
to be of the same quality through a thickness of 18 or 20 feet. There 
are no decided appearances of tlic boundaries of the deposit liavin^ 
been cut, except on the Pi.E. side, so that it may eventually prove to 
exceed the above-mentioned thickness. 
As far as can be seen from the outcrops and other indications, the 
deposit has nearly' every appearance of boiui^ a true vein or lode, in 
which case of course its deptli may be regarded as practically 
unlimited, for there is nothing on record which sliows that the bottom 
of any true vein has ever been rcacbecl in mining operations. Veins 
Lave often been regarded as worked out altogether when rcdnc(id 
perhaps to a mere thread, but, on continuing to sink, such veims have 
always been tmind to open out again. One cannot of course say that 
this will always be found to be the case, but it alwayvS has been the 
case, when sulUcient perseverance lias been used in following the traces 
of the vein downwanls. 
However, although there arc strong indications of this deposit of 
brown hematite being a true lode, it has not yet been conclusively 
proved to bo one; subsequent workings may sliow it to be an 
irregular deposit such as those of the Forest of Dean and other places 
in England. 
As the shaft already put down is sunk through the deposit itself, 
the stulb raised and heaped up at the shaft mouth aflbrds a very fair 
sample of the avei*age cnmlity of the ore. 
The ore is composed of nodules of raammillatcd and botryoidal 
goetliitc, possessing a librous slnicture something like that of wood, 
mixed Avith massive and friable brown hematite, togetlier with a little 
pipeclay. On descending the sliaft, its walls, on all sides and from top 
to bottom, are seen to he composed of the same ore, only, of course, 
from not having been disturbed it is much more compact. Hear and 
at the bottom, a “ horse” of pipeclay comes in, but one of no great 
size. 
A sample of the ore taken from the lieap at the shaft’s mouth, just 
as it Avas raised, and Avithout liaving undergone any dressing process, 
yielded on analysis the following results : —
