Clarification Regarding Supplies

In the fictitious land of immersion for this challenge, you find your team amongst the rock-strewn lands of a distant place. You can recognize that there is an abundance of metal ores around, along with abundant wood, clay, and coal. There is nothing beyond its primal state here. You are permitted to procure any materials in the form they are extracted from the ground, and base metals in scrap form. This permits copper, tin, lead, aluminum, nickel, iron, zinc, etc. Materials such as brass or bronze are not permitted until you have alloyed the metal yourself using base metals. You can purchase boxes or bags of clay. You cannot purchase processed materials such as grog, coke, or charcoal until you have produced them by yourself.

Up until the late 19th century aluminum was scarce. The process currently used was not invented until 1886. The material is far more commonplace today than the earlier white metal, tin; this is why I am including it in the challenge.
