I'm not sure. I'm currently focused on adding content which will likely take up the next couple months (Tech tree, more things to build, more combat related items, etc). And I'm going to add the next playable race (Ardyn) before starting any overworld map features. I've also learned to stop promising dates because, as just one fella, I usually can't guarantee I'll hit them.
Wait for Winter then "mine" the ice/snow walls that keeps on building up due to snow. You'll then have thousand of snowballs to creat Ice Chunks via workshop. Recipe will show up once you acquire your first snowball.
