For the bold and the brave…So, you buy a GDX June 90 @10.00 and sell a GDX 130 @1.85, so net outflow of around 8.15 to put on one contract.

Your breakeven is 12% above the current GDX price (@98.15) and your max gain is 300% at 130 or better.  Once I cash out of some GLD and SLV calls, this is how I will then play leverage.  I will go out at least 6 months to allow for crazy price moves. I have enough confidence to put on this trade and expect GDX to be at least 12% higher in June.  If it hits 130 (48% higher), you make 300%, basically 6x leverage.  Not investment advice, just what I plan on doing to turbo my gains in trading accounts.
