Is it likely that we will or could potentially find large deposits of metal on Mars like we would on Earth?

I'm curious because Earth only has a finite amount of metals, if we colonized Mars or say a moon of Jupiter, how likely would it be to find the same metals there that we find here on earth such as gold, silver and iron? Would we potentially find a new metal or element?

As others have pointed out, Earth and Mars formed from the same planetary disk, so the overall ratios of elements are probably pretty similar.

However, we aren't blending Mars into a smoothie- we only care about elements that are close enought to the surface to reach.

During planetary formation, most metals and heavier elements end up in the core, but some still get left near the surface. Meteoroid impacts also deposit more ores near the surface over time.

Edit: have been informed that the following last few sentances are incorrect, or at least nowhere close to the full story. Read on with healthy skepticism:

Earth is regularly resurfaced by plate techtonics (at least on long timescales) while Mars is pretty much frozen, accumulating more and more meteorite impacts. So Mars may very well have more abundant metal sources near the surface, conveniently marked by craters.
