To prove whether this is so or not requires work below the surface. 
Such work could consist in, say, sinking the old Armagh shaft to a depth 
of 300 feet, and cross-cutting to and beyond the reef. 
Similarly, the shaft on the Alice Maud line might be sunk to a depth 
of 100 feet, in order to determine the true nature of the reef formations.

Further Report on the Alice Maud Mine, Broomfield. 
The mine is situated about three-quarters of a mile to the south-east of 
the Broomfield Railway Station. Rich yields were obtained from surfacing, 
as mentioned in my report of April. At the time of my previous visit all 
the surface workings were closed, and no suggestion as to the origin of the 
rich alluvial gold was forthcoming. Subsequently, a local syndicate cleaned 
out a shaft in the immediate vicinity of where some of the richest specimens 
ivere obtained and found a vein of stone dipping westerly at a low angle 
and cutting through strata dipping to the east. An occasional colour of 
gold led the party to conclude that further west something payable would 
be found, so, with this object in view, they cleaned out and sunk to a 
total depth of 112 feet a shaft which had been sunk by a former party to 
a depth of 55 feet, at which depth the vein mentioned in workings detailed 
above, was cut. At about 90 feet from surface another vein, also dipping 
■west, was cut, and 8 feet below this a larger one was passed through. 
Colours of gold and small specimens were found in both these veins, and on 
reaching water-level in the shaft a cross-cut was put in westerly to intersect 
both the above veins on their downward course. This, unfortunately, was 
not successful, but the cross-cut shows an interesting section from a geo¬ 
logical point of view as affording an insight into a new feature in the 
structural arrangements of that portion of the field. Although the cross-cut 
is only 60 feet in length, three dykes, each distinct in appearance and 
almost vertical, were passed through; the strata on the eastern side of these 
intrusive masses have an easterly dip, and on the western side a westerly 
dip. (Fig. 31.)
