NEW YORK (TheStreet) -- Shares of Hecla Mining  (HL - Get Report)  were declining late Wednesday afternoon after preliminary July jobs data led to lower gold and silver prices.

Gold for December delivery was down 0.63% to $1,364 per ounce on the COMEX. Silver for September delivery was falling 1.24% to $20.45 per ounce.

Earlier today, unofficial July jobs data from Automatic Data Processing indicated that the U.S. added 179,000 private-sector jobs in the month, MarketWatch Reports.

This comes ahead of the Labor Department's official monthly jobs report due out on Friday. If the Labor Department report mirrors ADP's, the data could give the Federal Reserve enough confidence that the economy is strong enough to withstand an interest rate increase.

The Fed meets again to discuss interest rates in September, and if they agree on an increase, commodity metals like gold will lose some of their value as investors seek assets that provide a yield.

Hecla Mining is a Coeur D Alene, ID-based silver, gold, lead and zinc miner.
