No, but actinolite is, in many cases, associated with magnetite. Magnetite is a black gray metallic mineral that you can recognize because it will attract a magnet if placed close to it.
Another possibility could be hematite, in which the gray mineral should have a red strike.
I have never heard of actinolite associated to any kind of silver deposit. But the association with magnetite is common.
Let me know, I am very interested in actinolites.
Based on the additional description: That is soft, it flakes, and the association, it is most likely graphite.
Try writing in a paper with this material, if you can, then probably is graphite.

Actinolite does not (normally) contain silver since it is a silicate. The silvery stuff could be Muscovite, which is a mica. Check to see if the silvery material peels off easily, which is indicative of micas.

Actinolite is a mineral not a rock. To be specific it is an amphibole with the formula Ca2(Mg,Fe)5Si8O22(OH)2. It is a metamorphic mineral. The silvery mineral could be any number of sulphides occuring with the actinolite.
