Fossils usually contain single or multiple minerals such as Calcite, Quartz, Phosphate etc. Sometimes minerals are visible in the crystalline form in fossils. So, we cannot say that minerals are made of fossils. Instead, fossils can be made of minerals.
According to the prime and standard definition given by scientists, minerals are usually composed of chemical compounds or multiple compounds such a Halite which composed of Sodium and Chlorine elements. But they can be made of just one substance or element.
