Below are the coordinates for each Ancient Mana increasing item located in Suramar:

Kel'danath's Manaflask : 21, 54
Volatile Leyline Crystal : 22, 35 (temple entrance) - refer to video if looking for exact location in temple @ 2:42
Krytos' Research Notes : 27, 71
Infinite Stone : 34, 11
Enchanted Burial Urn : 45, 30

When following the lap to farm Ancient Mana in Suramar, I am usually able to obtain 1000 Ancient Mana in about 5 minutes. Sometimes it can take a bit longer depending on how many other people are in the area, but generally this isn't a large issue.

The more you stay in the center of each area on the minimap (follow the paths along Suramar City), the better range you have for covering each Ancient Mana spawn location.

As stated in the video, the following items will be the main means of obtaining Ancient Mana:
Leypetal Blossom
Leypetal Powder
Glowing Tome
Mana Gem
Twice-Fortified Arcwine

There are more ways to obtain Ancient Mana as well (Shoulder enchantment: Boon of the Manaseeker or purchasing Ancient Mana Gems / Ancient Mana Crystals on the AH) - but as for getting out there and doing it yourself, I find this is the best way to do so without having to fight any mobs.
