Dredging for Gold
IMAGE FOR A BIG VIEW IN A NEW WINDOW
is likely the Porter Brothers Corporation's electric Yuba
dredge working the old mine tailings which were north of Custer
Ave. and west of N. Montana Avenue. From November of 1935
to August 1943 the dredge worked continuously on the flats.
In that time 45,000 ounces of gold were recovered from gravel
that averaged 18 to 30 cents per cubic yard. Dredging stopped
in 1943 due to the war-time restrictions on gold mining. When
this ban was lifted in 1945, the Porter Brothers dredge worked
one more season. Total value of the gold from this dredge
was reported to be more than $2,500,000.
