THE MONS MEG AND UNITED MINERS' MINES, 
HARRIETVILLE. 
By /. P. L. Kenny . 
The Mons Meg Mine, Harrietville. 
The Mons Meg mine forms part of a group of workings extending south 
from Harrietville, between the east and west branches of the Ovens River. 
The group includes the Johnson, Lady Jane, Tiddle Dee, New Tiddld 
Dee, Jackass, Mons Meg, and Guerdon mines. The surface workings on 
the Guerdon reef are seen on the eastern side of the spur, just above the 
point where the new Harrietville to Omeo road crosses the old road. The 
Mons Meg reef outcrops 450 feet west of the Guerdon reef on the western 
side of the spurs. On the surface the Mons Meg reef has been worked 
for a length of 160 feet. The strike of the reef is N. 30 deg. W. and 
its dip is east 52 deg. The shoot has been worked down to the No. 6 
Guerdon level, a vertical depth of 550 feet, with highly payable results. 
At this level the shoot was 230 feet long and was worked from 5 to 15 
feet in width. 
The shoot pitches south at 55 deg. A winze was sunk 100 feet below 
the No. 6 level on the Mons Meg line and a drive north for 100 feet put 
in. From the end of this drive a rise was put up to the No. 6 level. 
This rise was within 10 feet of the No. 6 level before payable stone was cut. 
At No. 6 level the reef had a well defined hanging wall with solid 
stone and auriferous leaders running into the footwall country. The stone 
is said to have pinched out 10 feet below No. 6 level. Bunches of 
auriferous quartz were seen below No. 6 level. The winze is now full 
of water and the bottom of the stopes cannot be seen. The reef may 
have been disturbed by a slide or the stone may have pinched out. 
The average value of the stone milled from the Mons Meg reef was 
12 dwts. per ton. 
Taking into consideration the width and value of the stone where last 
worked, the Mons Meg is well worth further prospecting at deeper levels. 
The workings on the Mons Meg reef are not included in the present survey, 
excepting such as were necessary in the survey of the Guerdon mine. 
The Guerdon lode outcrops to the west of a diorite dyke. The reef 
strikes N. 10 deg. W. and dips E. 67 degs. The upper portion of the 
Guerdon reef has been worked from 3 adits driven into the eastern side 
of the spur. Some surface stone is said to have yielded 3 ozs. of gold 
per ton. No stoping has been done from No. 2 adit. The main dyke 
here is 25 feet wide and 10 feet east an offshoot 5 feet wide was passed 
through. At this level the reef was just on the western side of the dyke. 
The reef in the dyke has not been stoped. 
The No. 3 adit was driven by Messrs. Wilson and Hynd and cuts the 
reef at a depth of 180 feet. A shoot 50 feet long was worked to 70 feet 
above the level. 
About 500 tons were crushed from above the level, averaging 15 dwts. 
gold per ton. A winze was sunk 25 feet below the level and 30 tons 
crushed from the winze averaged 15 dwts. of gold per ton. 
No. 4 level was driven from the western side of the spur, the Upper 
Mons Meg adit being continued to cut the Guerdon line. 
No stone has been stoped above No. 4 level.
