They may appear brass-like because of the small amount of brown oil covering the particles suspended in oil. Light will play funny tricks....
The only way to be sure is to clean the particles in solvent to remove oil covering them. Use a magnet to confirm.

Take a look at the case oil drain plug. It's magnetic and you should see a silver paste covering the magnetic pole in the plug. That silver paste is more than likely the material of the cam lobe(s) and rocker arm(s).
