According TO the official report from the Con.
Cal. & Va. for the past week there has been a
material widening of the ore. which is being fol-
lowed south and upward in the south workings on
the 1850 level of.that mine On the sixteenth floor
(the eighth floor above the sill floor OF the 1850
leve) they worked south last week 9 feet in ore
showing width of feet, assaying from $50 to $40
per ton, and the top of the opening is in good
On the fifteenth floor, the previous week, the ore
was only feet In width. The south face OF the
sixteenth floor opening is in assaying $50 per
ton and the north face is in ore assaying from SO
TO S15 per ton, From the fifteenth and sixteenth
floors during the past week they extracted "a tons
OF ore, averaging per minecar sample assay S3s 35
per ton.

The Potosi mine during the past week shipped
1852 tons of ore to the Nevada mill. The battery
samples OF this ore averaged $26 45 per ton Dur
ing the week two bars of bullion, valued at
$4434 Az were shipped to San Francisco.
