Chalcocite is a copper(I) sulfide (Cu2S), an important copper ore mineral
Chalcocite is a copper ore mineral that primarily contains copper sulfide (Cu2S) as its main compound. It may also contain small amounts of impurities such as iron (Fe) and sulfur (S).

Perlite does not have a streak color because it is a volcanic glass that does not leave a streak on a streak plate.

Could be: Chalcocite, Galena, Molybdenite, Stibnite, or Jamesonite.
Chalcocite is a copper(I) sulfide (Cu2S), an important copper ore mineral
Copper(I) oxide - Cu2O - is the mineral cuprite.Copper(I) chloride - CuCl - is the mineral nantokite.Copper(I) sulfide - Cu2S - is the mineral chalcocite.
Chalcocite's chemical formula is Cu2S, meaning it consists of 80% copper and 20% sulfur by mass.

chalcocite
Chalcocite is commonly found in copper-rich ores, such as those found in the rocks of hydrothermal veins and in the oxidation zone of copper deposits. It is often associated with other copper minerals like chalcopyrite and bornite.
Copper is typically extracted from copper ores such as chalcopyrite, bornite, chalcocite, and malachite.
The streak of Jade is white.
Perlite does not have a streak color because it is a volcanic glass that does not leave a streak on a streak plate.
The lack of a streak would indicate that the mineral is harder than the streak plate, or the color of the streak is the same as the color of the streak plate.
