Help! .. heavy large mirror hanging
Discussion
It's a lot of weight in the context of what normally gets hung on walls, but it's below the shear strength of a single number 12 screw, so it's not that much weight really. The centre of gravity will be close to the wall so there's not really any leverage effect to consider, with a decent enough wall construction 4 screws would be perfectly fine. I would probably use 4 screws at the bottom, and one screw per restraining bracket further up and I'd probably only add a restrain to each side, two in total.
I can't see the pictures at work,but I would probably start with something like a length of 20mm box section and cut it to leave an L shaped section with a small upstand to the front. Drill the back appropriately, level it on the wall where you want the mirror and screw it on. Add a length of rubber tape to the rear and bottom of the L section and behind the upstand, thicknesses and dimensions done to give a snug fit with the mirror. You could tap the upstand and use bolts to clamp the mirror, but I think this is a weaker option aesthetically and wouldn't add much.
Then two restraint brackets up top, to stop the mirror falling forward. To install I would lift the mirror into place and lean something against it to hold it in place while you add the restraint brackets. My approach is based on doing something that allows you to easily install it, you can do all the drilling etc with the mirror out of the way and have it fully installed within a minute of starting to lift the mirror.
If you wanted a frame, I would do the above, then make a frame to fit over the top that is structurally independent.

I'd look to get a couple of metres of U section like the below, drill through it every 300mm or so and secure that to the wall robustly, to carry the weight & prevent it slipping forwards at the bottom.
Id then look to either use the same again up the sides to prevent any tilt forwards risks.
50KG is *not* to be messed with, esp on a wall where it could be nudged/moved as people walk past.
