How do I get those 3 last ores in the shotgun challenge?

[rogermorse]

There are 6 ores I think in the shotgun challenge (and 3 secrets, but the ores are not secret). Right at the end when you shoot the target and the hole opens and you are supposed to fall down, there is an additional target in the hole. If you shoot it, the shield in front of the ores gets disabled but each ore down the hole is still covered in glass so even if I fall next to them, I don't pick them up. I did not find any other tunnel / door to access them.....so... how ?

it says in the level selection or loading screen. you need to have a time of under a minute to get the final ores. then they are not shielded

Ok I will try. I was in fact wondering what they meant, since the first ores are not related to the time finish.

It doesn't help that it doesn't really tell you how many targets there are. I thought I had to get 100% kills and secrets.
