Then don't.
By the way, even though these mineral reports look pretty straight forward, they tell you nothing of how available the minerals actually are. All it tells you is there is x ppm iron, copper, zinc, etc. but does not indicate the form, how available, is it naturally chelated? If there was a high degree of biological activity eons ago where these volcanic\dust products are now being mined then chances are good there are also humic substances.
That's just another thing to consider, though, and why using a mix of remineralizers is probably the best idea. Not to mention, some heavy metals you really don't want in excess. Zinc, molybdenum, even iron can become toxic to plants and the people who ingest them. Of course, this is more likely after years of over-zealous application (or if the site was already contaminated).
