opened at pi'esent hj a small excavation of a few feet in depth. In 

 order to obtain an average sample, I had a couple of blasts put in, at 

 a distance of about twelve feet apart, at the bottom of the excavation 

 in question ; and from the fragments thrown out bj these shots, I 

 broke off nearly 40 lbs. of ore, taking a piece or two from each 

 fragment. A trial-assay, made on a small portion of the pure 

 mispickel in which no trace of free metal could be detected, gave an 

 equivalent in gold of no less than 8 ozs. 3 dwts., or $168, per ton ; 

 but portions taken fairly from the entire sample, and assayed side by 

 side, gave the following results :

The Cook or "Williams band is situated about a stone's throw east 

 of the Gillan exposure, on lot 7, of the 9th concession. A shaft has 

 been carried down along the slope of this to a depth of seventy feet 

 or more, and some drifting has been run along the course of the 

 band. The ore consists essentially of a mixture of mispickel and 

 quartz, and the free gold in it has yielded in the mill, during the 

 last two or three years, a pretty constant return of about nine or ten 

 dollars per ton. A very large amount of its contained gold passes, 

 however, into the waste slimes or tailings of the mill. I have 

 assayed a good many samples of this ore, taken from different parts 

 of the shaft and drifts. The lowest value obtained (per ton) was 

 $25.30, and the highest, $71 : the difference depending chiefly on the 

 relative amounts of quartz and mispikel, the highest yields being 

 invariably obtained from samples in which quartz was sparingly 

 present. On one occasion, I took the trouble to separate as carefully 

 as possible a considerable quantity of mispickel from its associated 

 quartz, and I assayed the two sej)arately, making duplicate assays in 

 each case. The quartz yielded merely a trace of gold, the buttons 

 on the cupels indicating by measurement (they were too small to be 

 weighed) about 1|- dwt. per ton ; whilst the mean of the two 

 mispickel assays showed 2 ozs. 19 dwts. 9 grs. of gold, and 2 dwts. 

 6 grs. of silver : or, in value, about $61 per ton. The so-called 

 " Feigel mine " is situated on lot 1 6, of the 1 1th concession, on 

 another metalliferous band of similar character. A considerable
