RECENT DEVELOPMENTS WITH THE CALYX DRILL 



exactly at one of these points where the strata would probably 

 be much distoited and broken. However, be that as it may, it 

 will be adm itted that the following attempts on the part of the 

 operators have proved eminently successful, not only in estab- 

 lishing the fact that large bodies of ore exist; but in assisting 

 to prove that the formation here is a true synclinal basin. 



The position for this hole was ch osen after some deliberation, 

 and it proved to be a happy one. At a point on F. Wheelock's 

 farm, about 2 miles to the west of the above workings, the 

 three veins spoken of in the first part of the paper, were proved 

 on the surface, and the drill was set up 40 feet to the south of 

 the most southerly of the three (the " Shell Ore " vein). (See 

 Plate V.) The crops of the other two were respectively 84 feet, 

 and 124 feet northerly from the drill. The three veins were 

 intersected at the depths shown, and by reference to the sectional 

 view, it will be seen that they are widening and flattening as 

 they descend. Boring commenced here on Jan. 3, 1901, and 

 finished on April, the drill operating for K60 hours: 



On the completion of this very satisfactory boring, the drill 

 was moved over on the south side of the valley, formed by the 

 Torbrook or Black River, and boring was commenced well up 

 on the South Mountain ridge. The drill was situated close to a 

 vein of compact magnetite, whose surface measurements gave 

 the writer the following results taken from north to south :
