Speed Blocks! - Speed Run Challenge

Hey Guys, Jerah Callaghan here. This time, I'm bringing my very simple "Speed Block!" challenge map to you!

It's very simple. There are a couple of islands, as shown above. In those islands I've hidden some ore. Your job is to get that ore, turn it into blocks and put them on the monument as fast as possible. But! In order to do that, you're required to think.

There are four types of or, that can be found.
Gold, Iron, Diamond and Emerald.

Some rules:
Don't break Glass or Slabs.

Some other thingies:
Try and find the hidden chests, they contain valuable items!

How fast are you?!
Post your scores in the comment section down below, and link (if possible) some video footage!
The fastest three with proof will be listed in the post, right about.. here:
