Slowgoing and dangerous it may have been, but ancient mining techniques were clever. The earliest mines sought cosmetic pigments for funerals. Picks and hammer stones are examples of stone age tools. Later, ancient man discovered metals which provided materials for superior weapons and tools.

Syenite is a coarsegrained intrusive igneous rock with a general composition similar to that of granite, but deficient in quartz, which, if present at all, occurs in relatively small concentrations (< 5%).Some syenites contain larger proportions of mafic components and smaller amounts of felsic material than most granites; those are classed as being of intermediate composition.
A small highgrade (1620 g/t) gold mining operation was centered on this discovery during the 1930''s. Historic records indicate that Northshore Gold Mines produced tons of gold ore from the Northshore Zone at an average grade of oz/ton ( g/t gold.
