Interesting find!

As you mentioned, perlite is mined close by. And the white powdery-textured stuff of your specimen resembles perlite.

At first glance, the cementing material looked to me as micro-crystalline quartz. After a brief search, I see that silica is also occuring there - see image here https://www.milosminingmuseum.com/wp-content/uploads/2011/11/Picture-2.png where the grey points indicate silica occurrences.

So my suggestion would be perlite with the cementing stuff being micro-crystalline quartz.

Cheers,
Prodromos

Thank you for the information!
I had the impression it would be perlite because of the occurrences you mentioned above and also the mine being in close proximity.
I will do more research,

thank you again

Uwe Kolitsch:
I agree with Podromos: microcrystalline quartz.

Adamites:
Thank you for your message.
