The first time loading up Kirite on a new game can follow a path like this, normally you could go from point to point but talking to the refinery is delayed due to dialogue between Atlas characters so you can hit up one of those Electrum Veins then to the refinery after grabbing 3. Similarly, when you kill the Extractor and return to the refinery you can hit the other Vein for a bit more whilst they talk about St. Grand. this should give you just enough for later when you finish Haven to have 50k to buy the Equinox upgrade.
