 Aluminium is much more common than copper, by many orders of magnitude.  Although it requires more energy to produce it can serve as a good replacement for copper.
-Copper on Earth is usually found in ore with concentrations of about 1%, while volcanic rocks can have concentration between 5 and 25% for alumina,  Bauxite has concertation of more than 50% and clays of about 15-30%.  Due to low concentration copper ores usually require on site concentration before shipping.

 Copper is found either as sulfides, or as oxydes, that require different concentration processes.
 On Earth, copper is extracted at a ratio of about 0,6% compared to Iron (1:150). And 1:3 compared to aluminum.

 ===Food===
 Copper is an essential trace element in food. A typical human body contains 0,000072 kg. For one million persons the copper required would be 72 kg. For an entire ecosystem serving these one million people the amount required might be about ten tonnes (hypothetical ratio of 100:1). Martian regolith might need to be slightly enriched in copper to serve as soil.
