Picks & Pans: Basic Dry Washing Operations in Gold Placer Mining. September 1999 by Staff . Some of the advantages of dry washing operations are low overhead costs (inexpensive methods and equipment), and the fact that many mining operations can be conducted by one or two individuals.
Surface mining and processing at the rate of up to 100 tons per day with large equipment meant that the mine operated for an average of only about 20 days each year for the life of the operation. As sales and mine operations were based solely on demand and landfill activity, there was no production during 1996 and 1997.
lic operations. For the next 14 years, drift mining placer gold deposits in buried Tertiary channels partially made up for the loss of placer gold production, but overall production declined. Production rose again with the advent of large-scale dredging. The first successful gold dredge was introduced on the lower Feather River near Oroville in 1898.
Some modern commercial placer operations are quite large and utilize heavy equipment and river diversions. Placer mining targets "native" gold that isn't chemically bound up within the rock itself. The sources of all placer gold are "lodes", or veins of gold naturally formed within the rock.

The cost of hydraulic mining depends largely on the magnitude of the operations. With large quantities of water available at a cheap rate, and big banks of soft gravel, the cost has been reduced in California, while the average cost was about low cents, and only in exceptional cases amounted to as much as 5x higher per cubic yard.
“Cash cost per ounce of gold” was purported to provide transparency into the economics of gold mining operations. However, it excludes some expenses and capital items that drastically reduce a company’s bottom line profitability.
If the overburden only contains $2 of gold per yard, and your mining cost is $5 per yard, then you are losing $3 for every yard put through the wash plant. On the other hand, if you can strip low-grade overburden for $1 per yard, then you have saved $2 per yard which can be directed toward mining the pay gravels.
The total cost of producing an ounce of gold in Canada increased from $22.35 in 1939 to $32.07 in 1945, according to the report of the director of the Ontario Mining Association for 1945. This represents a 43.5 per cent increase.
