Codex Rift Mining

Mining

With the rift open at a surveyed address, the Extraction Array works its deposits. Every deposit is worked by one extraction job; the matter goes into the buffer of the Matter Receiving Facility, from where pipes take it out.

Deposits

Every address holds 3 to 6 deposits, one more from phase 6 on. Each deposit belongs to a material family (iron, lava, argon and so on, see Rift materials) and is one of three types:

Type	Amount	Rate	Special
Finite deposit	normal	normal	Runs dry for good.
Regenerative deposit	0.6 times	0.8 times	Recovers 2 % of its first amount per in-game day.
Abundant, rate-limited	12 times	0.45 times	Huge, but slow.

Higher phases make deposits richer (8 % more per phase). Purity, a hidden value of every deposit, raises its rate. The survey shows where the deposits are and what they hold; their type and reserve show once the address is analysed.

Starting a job

1. Open the rift at the address and wait for the survey (the console shows a progress bar under DEPOSITS).
2. Look at the open address and select a deposit (in the list or in the scene).
3. Choose the method, if there is more than one, and the rate.
4. Press Extract: "Extraction job #… started."

Rules:

• One job per deposit. A stopped job on the deposit is resumed instead ("Job #… resumed.").
• At most 3 enabled jobs at once, two more with Parallel Extraction ("At most … jobs at once."). Enabled jobs at other addresses count too: stop them when you move on.
• At most 32 jobs in the list, also stopped ones ("The job list is full (… jobs): remove one first.").
• A job at another address waits ("waiting for rift") and works again when the rift opens there.
• A deposit whose material no installed mod provides cannot be worked; the console marks it with ⚠.

Methods

Each deposit has a standard method; research adds two more.

Method	For	Rate	Energy	Notes
Surface sweep	Items, shallow deposits	1	0.9	Standard for ore near the surface.
Deep core drill	Items, deep deposits	1	1.15	Standard for deep ore.
Fluid pump	Fluids	1	1	Standard.
Atmospheric harvester	Gases	1	1.05	Standard.
Precision lance	Items	0.7	1.6	Research Precision Lance. Each delivered unit takes only 0.8 units of the deposit, so it lasts 25 % longer.
Anomaly harvest	Everything	1.25	2.2	Research Anomaly Harvest. Only in Anomaly worlds or on Rift Crystal and Phase Plasma deposits. Every 64 items or buckets taken also make one Rift Crystal.

Rate and energy

• Units per second = rate of the deposit × the job's rate factor × the method's rate × the sector yield (Sectors). Items count one each, fluids and gases in mB.
• The rate factor is chosen with Rate ×…: from 0.25 up to 4.0 (rift.extraction.maxRateFactor (default 4.0, allowed 0.25–16.0)).
• Energy per unit = base × (rate factor)^(exponent − 1) × method energy × difficulty of the address × the material's value (rare materials cost more) × 0.8 with Harmonic Drills. The base is 12,000 FE per item, 40 FE per mB of fluid and 60 FE per mB of gas.
• The exponent is 1.35 (rift.extraction.rateEnergyExponent (default 1.35, allowed 1.0–3.0)). A higher rate factor therefore costs more energy per unit: twice the rate costs about 27 % more per unit, half the rate about 21 % less.
• The console shows the energy per unit of each job in its tooltip.
• The jobs are booked every 10 ticks. Nothing is extracted that does not fit into the buffer or cannot be paid; the fraction of a unit is carried over.

Job states

State	Meaning
running	The job extracts.
receiver full	The buffer of this class is full. Nothing is extracted and no energy is used. Empty the output ports.
no energy	The store cannot pay one unit.
waiting for rift	The rift is closed or open elsewhere.
depleted	The deposit is empty.
material unavailable	The material of the deposit is no longer provided by an installed mod.
stopped	You stopped the job.

Managing jobs

In the job list of the console: ⏸ stops a job ("Job #… stopped."), ▶ resumes it, ✕ removes it ("Job #… removed."). The progress of a deposit stays with the deposit, not with the job: a new job goes on where the old one stopped. Rift Crystals a removed job still owed are delivered later.

Once a deposit has given its first unit, it stays bound to that material, even if another mod later provides the same family.

Messages

Message	Meaning
The rift is not open.	Jobs only start while the rift is open.
Select the address the rift is open at first.	Look at the open address (View open rift).
Deposits are not surveyed yet; keep the rift open for a while.	Wait for the survey.
Unknown deposit.	Select a deposit again.
No installed mod provides this material (…).	The deposit cannot be worked in this pack.
Job #… already works this deposit.	One job per deposit.
This method cannot work this deposit (research or place): …	Research the method, or it does not fit here.

Tip

Balance rate and energy The lower the rate factor, the cheaper each unit. Raise it when you need the matter fast and have energy to spare; lower it to 0.5 or 0.25 when energy is short.
