Bikerafting The Sacred Headwaters
I've been to this mine as a sub-contractor and stayed in the mining camp. I would say that 75% of the workforce was aboriginal. It's a very rich copper deposit which includes some precious metals as a profitable by-product. The mine is currently open pit but will likely have to switch over to conventional as they progress. Compared to something like the oilsands in Alberta, this type of mining is relatively clean and environmentally friendly.

To the Point: Heat Treating Aluminum Frames
This is not correct. The initial heat treatment is to dissolve the alloying elements in solid solution (solution anneal). The artificial aging causes very fine and evenly distributed precipitation of solutes inside each aluminum grains structure. There is absolutely no crystal structure transformation. The shear transformation you are describing occurs when hot steel is quenched and then followed by a lower temperature thermal treatment.
