The nickel in the Oregon deposit occurs in both the peridotite and the overlying soil. A deep lateritic-like soil is developed locally on the peridotite and serpentine and constitutes the ore. The average nickel content of the lateritie soil is less than one per cent, whereas the nickel content of the peridetite is about 1 to 1.5 per cent. The nickel occurs as garnierite (Mg, Fe, Ni, Mn)3(OH)4 ...

Quartz is extracted from open pit mines. Miners only use explosives on rare occasions when they need to expose a deep seam of quartz. The reason for this is that although quartz is known for its hardness, it damages easily if it is suddenly exposed to a change in temperature, such as that caused by a blast.
