Don't forget, you can make your own (much stronger) by killing some
hydrochloric acid with a handful of zinc. (I presume you have zinc lying
around if you're galvanising stuff.) Otherwise use scrap galvanised steel.

Sadly, when you melt gold found in nature, especially if it runs low in gold
(less than 90%), melting it usually results in some pretty ugly material.
Pure gold has a wonderful color and luster, which is readily lost when
alloyed, When the alloys are dirty, such as are typically found in nature,
it's not unusual for the gold to turn out frosted and dull in appearance.
The nuggets have been abraded and mauled, plus aged (for coloration) such
that they tend to be far more attractive. I'd recommend you friend either
enjoy what he has the way it is, or learn refining techniques and purify the
metal before casting a common bar.
