HALIFAX COUNTY, N. S. BY HARRY PIERS 41 



property, Aloose River, Halifax County, about 2§ miles due east 

 of the Scheelite mine at Scheelite. (See museum ace. no. 

 4796.) It was apparently in a well-defined ore-shoot confined 

 to the sharp fold referred to. 



Apparently all of these eleven deposits of Tungsten ore 

 in Nova Scotia, are associated with quartz veins (mostly 

 interbedded ones) in the Quartzite Division of this Gold 

 Measures, (Lower Cambrian or possibly Pre-Cambrian age), of 

 Halifax, Lunenburg and Queen's. Counties, wnth the exception of 

 the ores about Lake Ramsay and New Ross, Lunenburg Co., 

 which are in pegmatite in Devonian granite, and the Hubnerite 

 at Emerald, Inverness Co., which is in Pre-Cambrian rocks. 

 Tungstite is liable to occur as an alteration product at any of 

 the known deposits. Scheelite is the most common ore here, 

 and it is usually associated with more or less arsenopyrite. 

 The only deposit which so far has been commercially worked, 

 is that at Scheelite near Moose River. 



Discovery of the Sackville deposit. — In September, 1921, 

 Frederick W. Dixon, while prospecting a 2Kinch quartz vein 

 in an outcrop of quartzite on his. property at Lower Sackville, 

 Halifax County, N. S., discovered arsenopyrite in the vein, and 

 brought samples to the Provincial Museum for determination 

 on the 23rd of that month. (See museum ace. no. 5026.) 



On continuing to prospect the vein, he found that it widen- 

 ed to six inches or more; and on 3rd of October, he discovered 

 therein another mineral. Not knowing what it was, he brought 

 a sample to the Museum on the next day, (see ace. no. 5038). 

 This was identified as a brownish-pinkish-buff coloured Scheel- 

 ite in white quartz, the Scheelite having tabular-shaped cav- 

 ities which had been left unfilled at the time of deposition, and 

 which give it a sort of semi-cubical appearance when broken. 

 Thus it very greatly resembled in colour and general appearance 

 the Scheelite from Perry Lake about a mile northwest of Wav- 

 erley, which had been discovered in 1908. A little yellow Tung- 

 stite (oxide) also showed on one of these specimens (ace. no. 

 5039). I told Mr. Dixon he had better immediately take up 

 the mineral rights to the property, which he did; and on 10th
