Anky and argy with solo Dino farm mod. Red rocks all around king titan terminal. You’ll get tons of silicate

You Can use Anky to Farm it got a lot more

Silicate is replacement for Pearls on Extinction due to no ocean, they can be found all around the king titan battle arena near the north top part of the map, nothing typically spawns near the arena so it’s much safer to go there then in the red tree valley, The dreadnoughtus Saddle uses a lot of pearls so it’s preferred to harvest them then to produce them through gachas in my opinion

You can mine them like stone and metal, think they replace silica pearls. Seen them in extinction

some times, people need a hatchet instead of a pick.

i use a hatchet and it gets me 3x more than a pick of the same dmg value.
