You'll want to keep going beyond the large alien tower until you reach an area where you'll see what almost looks like a large dome with various structures inside. Specifically, this location is about 1,780 meters directly east of the lifepod, and at a depth of about 300m.
Once you're under the dome, which has a large pole-like tower going up the middle of it, you'll see several cliff ledges inside with something that almost looks like shiny metal coral on it. These shiny materials are the Conduit Crystals.
At this point in Early Access, this dome is the main location where you'll be able to find Conduit Crystals, and you'll need the Sonic Resonator to collect them.
Unlike some of the other materials in the game that can be found in several locations across the map, Conduit Crystals will only really be found in one area. As mentioned, after you visit the Tadpole Pens and access the NoA companion Terminal there, you'll receive a new marker that leads to Alien Ruins.
This area will be across the large gap where the Collector Leviathan swims around, so it's recommended that you use your Tadpole to reach it, ideally with the Scout Ray Chassis attachment. Once you're in the area, you'll see several large alien-like buildings, including one that has a tower reaching up to the surface.
