<br />' $2.50 to $3.50 per ton, including cost of roasting, treating sixty tons of tailings per day. A fair estimate would proUnUly

<br /> say value, or $16.32, we have a profit of $12.82 per ton, or a t otal of $9,615, more than sufficient to pay the building and
<br /> equipment of the plant, leaving it unencumbered for the trea tment of ore from the mines or tailings from the new mill.
<br /> We know that at least one of the group of mines contains, in pa}'ing quantities, ore which is amennUle to cyanide
<br /> treatment and this will be worked by that process; and it is not unlikely that we may find it economical to treat the tail-
<br />: magnitude and rieh• tags from the mill also. The mill will have a capacity of twenty-five to thirty tons daily. The cyanide plant we intend
