Metres 1 * 1 °^ ^ e dome, but none have been very product- 

 ive. The Baker vein, a quarter of a mile east, 

 is, however, of especial interest as being the only 

 one in the district that crosses the stratification 

 for any considerable length and has proved 

 very productive. It lies in a fault-plane which 

 cuts the anticline at right angles, and, unlike 

 the interbedded veins, it has much gouge and is 

 very irregular in thickness and crooked in 

 strike, The average thickness of the vein 

 is 1 8 inches (0-45 m.), and the average yield of 

 the ore 5 to 7 dwts. Several 100-ton lots gave 

 1 1 to 2 ounces. The vein cannot now be seen 

 at the surface. 



The Hardman mine is on the Dunbrack lead 

 in a westerly direction from the Schaffer Barrel 

 lead across the anticline. This lead lies on the 

 footwall side of a bed of slate interstratified with 

 quartzite dipping southeast 43 Apart from 

 the rolls, the thickness of the vein varies from a 

 fraction of an inch to 8 inches and may average 

 4 inches. The vein is corrugated and the corru- 

 gations pitch east 38 like those directly north 

 on the footwall of the Schaffer Barrel lead. 

 Two well-defined and parallel ore-shoots or rolls 

 have been worked in the lead, the Ned McDonnell 

 shoot and the Hardman shoot, pitching east at 

 a lower angle than that of the corrugations. 

 The upper one, the Ned McDonnell shoot, does 

 not quite reach the surface but was worked for a 

 length of about 850 feet (259 m.) on the pitch 

 to the first fault of 112 feet (34 m.), beyond 

 which it has not yet been discovered. The 

 quartz and slate measured in vertical section 

 8 inches in thickness and 9 feet in breadth, 

 having been thickened and enriched by small 

 angulars entering from the footwall side. 



The Hardman ore-shoot, which was probably 

 the richest one worked in the province, lies 

 about 140 feet (42 m.) below the Ned McDonnell 

 roll and runs parallel with it. It does not reach 

 the surface, but lies at a depth of about 175 feet, 

 and a little east of the western end of the Ned 

 McDonnell roll, where it originates like the latter
