Mass Effect has several "uncharted world" assignments for players to pick up and complete for bonus experience, credits, and memories.

One of these—and, arguably, the longest of them—is the Valuable Minerals assignment. Players can pick it up upon finding a deposit of a certain resource by either surveying a whole planet or dropping onto its surface with the Mako and investigating the physical resources, themselves. There are four types of resources to find: heavy metal, light metal, rare earth, and gas. The first three require 20 deposits to complete the assignment each while gases only need six.
