Where did you get this information? It's ... well... just wrong.

1. Neutron stars are not primordial, they are the remnant of earlier massive stars that exploded in supernova events.

2. Neutron stars are not rare, in fact they're far more abundant than previously thought. It's mainly a problem of detection, since they're so small.

3. The supernova event is the principal (and possibly only) source of elements with atomic number higher than Nickel-62. Ordinary stars produce elements up to iron & nickel. The higher numbered elements are produced by the density and energy conditions present when a massive star collapses then explodes (supernova). Neutron stars are the remnants of these events.

4. Some recent arguments have been made that attribute the production of gold to collisions of neutron stars. This (as yet unproved) hypothesis attempts to account for the shortage of observable gold, which is below the amount estimated for supernova production, but even if true, it's certainly NOT the source of all the gold in the universe.

This can all be verified with a wiki or google search.
