The embark I've just started on, I have everything I need and all the skills I want. I bought up all the "free" barrels and bags. However, no magnetite, hematite or limonite, no lignite or bituminous. No iron goods available, though there is steel, both bars and armor/weapons. The only flux is marble, the only magma-safe is quartzite, the only ores sphalerite, galena and tetrahedrite. (Maybe it's a sign I'm not supposed to run for the magma this time.) How would you spend the remaining 700+ points?
My 3x3 embarks always have flux in one of the biomes, so when the ore options on embark are limited, I plan on trade/invader/mining to obtain iron and copper and ignore the expensive steel bars. I take about 10 tetrahedrite to get some early silver for weapons to sell in the first year and then spend a lot on sphalerite, bismuthinite, and cassiterite, most of which sits idle until I get to the magma. Copper always shows up from invaders, traders, or mining, so the sphalerite is for brass mugs/tradegoods, the bismuthinite is a stone-substitute to make blocks
in case I need to make a d-slit to get through the aquifer to get to more stone and the remainder is for bismuth bronze, and the cassiterite is for the bronze alloys (because if there is an iron shortage then bronze will be useful for armor). I still race for the magma for the cheap smelting costs. You could also buy 50 turkeys and butcher 40 of them in the first few months, for a large pile of meat and leather. This takes a lot of dwarf labor but if the surface is evil/untamed and there is an aquifer, it will keep some dwarfs busy while you are trying to get through the aquifer to get to stone.
