Passed by  this place  where  these  guys  are  mining this  way. Was  curious, what  type of  rock is this?

Hi.Rios.Looks to be a sediment type rock with all kinds of mineral content.It might not have a speficic name with all that mineral.It is not shale as we know it.If it breaks easy.I would stick with my first guess.Any old volcanic signs in the area?Luck Mcbain.
I started out with nothing Istill have most of it.

Google reveals some studies of the area's  geology and various minerals found at the How Mine.  I suggest you start your study there.

Broadly speaking though -How Mine is situated in the Bulawayo greenstone belt and exploits several individual mineralised pods situated within a sigmoidal structure which dips at 70 to 80 west. The pods are broadly cigar-shaped bodies comprising zones of enhanced hydrothermal alteration and gold mineralisation that plunge steeply. Mineralisation within the orebodies consists predominantly of pyrite (>90%) with minor chalcopyrite and pyrrhotite and is associated with silicification and carbonation. Gold is found in contact with the sulphides, often in fractures, although there is also some free gold. Some silver occurs with the gold, increasing from 4% to 8% of gold as mining progresses down-dip.
