There is a large countity
Elemental gallium does not occur in nature, but as the gallium(III) salt in trace amounts in bauxite and zinc ores. Its abundance in the Earth's crust is approximately 16.9 ppm. Gallium is found and extracted as a trace component in bauxite and to a small extent from sphalerite. The amount extracted from coal, diaspore and germanite in which gallium is also present is negligible. The United States Geological Survey estimates gallium reserves to exceed 1 million tonnes, based on 50 ppm by weight concentration in known reserves of bauxite and zinc ores.
Gallium as gallium nitride, GaN is found in leds and laser diodes in Blu-ray disc readers. In nature gallium is found in trace amounts in bauxite along with aluminium and in zinc ores.
Gallium is the element. It is a low melting silvery soft metal. Gallium nitate is a compound containing gallium, a salt of gallium(III), Ga(NO3)3
Gallium is a metal. It is next to germanium, a semi-metal.
The abundance of platinum in the Earth crust is 0,003-0,004 ppm.

There is said to be about 0.0015% of gallium found in the Earth's crust with no known concentrated supplies of it
