There are a total of 85 secrets in Siberian Mayhem.
This video by Methos shows the locations of all 85 secrets in the game. I obviously take no credit for this.
Timestamps from the video above for each level:
A Smell Of Petroleum Prevails = 00:15 (16 secrets)
The Song Of The Stormbringer = 06:22 (11 secrets)
Siberiade = 11:47 (27 secrets)
Roadside Picnic = 27:11 (16 secrets)
Crime And Punishment = 34:54 (15 secrets)
If you find all secrets in the levels as you play through them from the beginning, you will also get the Sam The Explorer achievement midway through Siberiade. Make sure to not miss the secret classic levels!
Another heads up: be careful when doing the Valley of the Kings secret in the first level — it is possible to get softlocked if your health is at 200 (300 on Easy or Tourist) and you cannot pick up the Extra Large Health (red heart pickup) that spawns after killing all the enemies in the secret arena. If that happens, make sure that you get damaged before you kill the final Kleer Skeletons in the secret arena.

Video is working great!
Just want to add that I got several during my first co-op run and after getting a few new ones on the first mission solo, my halfway achievement popped. Looks like these carry across playthroughs, including co-op to solo.

Another note, be sure not to use your C4. You'll need it for the secret classic levels.
