Income call
For income on GDX you already hold: sell the Oct 30 $110 call and take $99 now. If GDX climbs to $110 by Oct 30, your 100 shares are sold at $110, so only do it if you're happy selling there.
If it climbs past $110 your 100 shares are sold at $110 and you keep the $99. That is the trade working, not a loss.
