To the west of the Ovoca River are the West Ovoca Mines, 

 including the two Ballygahans and Ballymurtagh. 



Ballymurtagh and Lower Ballygahan are divided from the 

 East Mines by a channel of dead ground in the Ovoca River 

 Yalley, which heaves (left hand) the latter northward. In these are 

 the North and South^sulphur lodes ; while south of the latter are the 

 Standing coppery lodes, all the lodes being in character respectively 

 similar to those in the Tigroney and West Cronebane setts. There 

 is a slight left-hand heave near the boundary of Ballymurtagh 

 and Ballygahan. East of this, in the latter, the north lode 

 carried coppery ore only ; while in the Ballymurtagh North lode 

 there is a gossan of iron, or ochre, on a rich sulphur lode. Here 

 there was no gossan lode ; but in places between the gossan and 

 the lode was a large "[vug " full of water. Much of the ore in 

 these lodes is still unbroken. 



In Ballymurtagh, between the North and South lodes, there 

 was a shoot of ore, " Pond lode : " this is worked out. In the 

 South lode, Ballymurtagh, the ore has been broken more or less 

 to 110 fathoms below the Margaret level, and in Ballygahan to 70 

 fathoms below the adit, the deepest working in the first being 

 24 fathoms below the deepest in the last. At the breast of the 

 workings in Ballygahan, at 60 fathoms, the ore gave 37 units of 

 sulphur, and 4*4 units of copper, the course being over 11 fathoms 

 wide, the south hanging wall not having being reached. Bally- 

 murtagh and Ballygahan would be more profitably worked as one 

 mine; because at any time, on account of the underlie of the 

 South lode, the portion in Ballymurtagh could be undercut by 

 a level in Ballygahan. 



In Ballymurtagh South lode there was a lenticular mass of an 

 ore allied to Kilmacooite, it in places being very auriferous. 1 



In no place in either Ballygahan or Ballymurtagh has the 

 bottom of the lode being reached; while in both there are good 

 breasts of unbroken ore. Copies of all the plans and sections of 

 these mines are lodged in the Mining Record Office, London. 



1 In Culvert's analysis, in five out of six, there is a return of gold, 'while in the 

 analysis by Apjohn and others no gold was found. This is another example of the 

 care with which specimens should be selected. Culvert's specimens were from this 

 peculiar ore, which did not represent the true lode, and therefore raised a false hope.
