RE:Does Trevali produce zinc??????????Nirmalcharts, Trevali does produce zinc, but they hedge a lot of their production at a price lower than what it costs them to produce. They have bone headed management that hedges at a guaranteed loss while they mis-manage their mines to the point where costs are completely out of control. Investors are attracted to this stock because they think a billion shares is a reasonable number, they do not mind losing money on hedges, and they think rapidly increasing mining costs are okay.
