I've been playing this map quite recently and I can't seem to find any scrap metal resources (being mineable rocks). Am I not looking hard enough, or are there none?

If there are none, is there any possibility of these being added in the near future?

Brilliant map otherwise. Well, apart from me finding a total of 4 helicopters - all of which were props :(

Edit:
I've ended up just modifying the map myself - adding the rocks and changing some things around to better suit I and my friends' ideas. I do not intend on distributing this to anyone other than my small group and will not be uploading it to the workshop.
