THE SALT LAKE CITY SILVER ORE MARKET.
Mr. J. B. MFADER, assayer, gives the following statement of the ore and metal mar-ket for the week ending July 15 :
Argentiferous Lend (Base Bullion).—$80 per ton for lead; $1.08 per oz. for silver ; $20 per oz. for gold. The above quotation for silver is based upon a silver contents in the load of 80 to 100 oz. per ton of 2,000 lb.
Argentiferous Lead Ores.—From 90c. to $1.00 per oz. for the silver contained therein based upon a standard of 40 per cent, lead, each unit above 40 per cent. 50 cents per-unit added. Each unit below 40 per cent. 50 cents deducted. Extreme prices, and only for most desirable carbonate ores, free from zinc, copper, and antimony. Ores containing zinc—For each unit of zinc above 5 per cent., deduct the value of 1 oz. of silver. Ores with a lime or ferruginous gangue subject to higher rates. Copper in all the above ores objectionable.
Copper Ores.—Assaying 20 per cent, net assay, $1.40 per unit (or percent.) ; assay-ing 25 per cent. net assay, $1.70 per unit (per cent.) ; assaying 30 per cent. net assay $1.92 per unit (per cent.) ; assaying 35 per cent. net assay, $2.30 per unit (per cent) ; assaying 40 per cent, net assay, $2.25 per unit (per cent.) ; assaying 45 per cent. net assay, $2.35 per unit (per cent.) ; assaying 50 per cent. net assay, $2.45 per unit (per cent.) per ton of 2,000 lb. To obtain the net assay, 1 and 3-10 per cent. is deducted from the wet assay. Silver has improved somewhat during the week, yet it is by no means settled that it will not still further decline ; therefore buyers are slow to take up engagements for the future, and are only purchasing from day to day ; this makes the market unsettled and panical.
