It definitely has the color and habit to be annabergite. Though there are many other minerals that can fit that habit as well, such as malachite. Are there any indicators that would identify the deposit as a nickel deposit?

I just did an acid test and its not fizzing so its not malachite ummm what would i look for exactly? sorry im new to all this haha :)if this helps the rock it was in has some light green in it does gaspeite form with nickel deposits? Because the light green stuff around does fizz with the acid.I will post a picture of the rock it was in.

See if you can get a close-up of the crystal structure of the radial spray. Annabergite has a very distinct crystal termination as flat bladed crystals that are angled. The matrix fizzing in acid is not an indicators since it could be a form of calcite (i.e. limestone)
