NEW YORK (TheStreet) -- Shares of Hecla Mining (HL - Get Report) are advancing in late-morning trading on Tuesday as the stock was upgraded at JPMorgan and gold and silver prices rose.

JPMorgan boosted its rating on shares to "overweight" from "neutral" with an $8 price target earlier today, the Fly reports.

The firm said the company has "high quality assets in increasingly attractive locations."

JPMorgan's price target implies 17% possible upside in the stock, the Fly noted.

Additionally, gold and silver prices are getting a lift from a declining dollar today. Precious metals are less expensive to foreign investors when the greenback is weaker.

For December delivery, gold was up 0.4% to $1,346.70 per ounce on the COMEX this morning. Silver for September delivery was rising 0.35% to $19.87 per ounce late this morning.

Hecla Mining is engaged in discovering, acquiring, developing and producing silver, gold, lead and zinc.

Separately, TheStreet Ratings Team has a "Hold" rating with a score of C on the stock.

The primary factors that have impacted the rating are mixed. The company's strengths can be seen in multiple areas, such as its revenue growth, largely solid financial position with reasonable debt levels by most measures and expanding profit margins.

But the team also finds weaknesses including disappointing return on equity, weak operating cash flow and feeble growth in the company's earnings per share.

Recently, TheStreet Ratings objectively rated this stock according to its "risk-adjusted" total return prospect over a 12-month investment horizon. Not based on the news in any given day, the rating may differ from Jim Cramer's view or that of this articles's author.
