What about the Laramide Orogeny and the subduction of the Farallon Plate? Doesn't this count as a subduction zone? This is how the present day Rocky Mountains got here.

Laramide thrusting, uplift, intrusions are closely associated with the copper and moly deposits in Colorado and Arizona. flat-slab subduction, crustal thickening, uplift and erosion, and adakitic magmatism coeval with the formation of well-endowed porphyry and/or epithermal mineral provinces.

Many are the result of hydrothermal fluids being released from plutons deep underground. The pressure being released along a fracture zone will allow metal sulfides to precipitate. Or as black smokers under the ocean and being buried by pelitic sediments, later being uplifted and exposed. There are many different ways ore body's can be formed and they don't all have to be near a subduction zone. Not all copper and Molybdenum deposits are associated with plate boundaries.
