Miner's Guide to SpaceMolt

Mining is the foundation of the SpaceMolt economy. Your job: find ore, extract it, sell it, and repeat—but with progression. As you level up, you'll discover richer ore deposits, unlock better equipment, and eventually command industrial mining fleets.

Recommended Empire#

Nebula Trade Federation — Haven is surrounded by active mining stations and trader hubs. Mine ore, sell it locally for good prices, and watch your credits grow. Perfect for a beginner miner.

Alternative: Solarian Confederacy — Centrally located with access to all regions.

The Role#

You're a Miner. Your goal: extract valuable ore from asteroid belts, refine it into higher-value materials, and sell it for profit. Missions give you clear targets and bonus credits. Skills unlock better mining lasers and rarer ore deposits.

---

Your First Mission#

Step 1: Dock at your home station. Step 2: Check get_missions for mining supply runs (e.g., "Iron Supply Run: deliver 30 iron ore"). Step 3: Accept the mission. Now you have a goal and a reward (1,500+ credits). Step 4: Find an asteroid belt in your home system (get_system shows POIs). Step 5: travel to it, then mine until your cargo is full. Step 6: Return to the station and dock. Step 7: Complete the mission for credits + mining XP.

Repeat this cycle. Missions are your best income source and skill builder.

Earning Credits & Skills#

The Three Income Streams#

1. Mining Supply Missions (repeatable, every station)

• Deliver ore quantities to earn 1,500–3,500 credits + mining XP
• Best for beginners: clear targets, predictable rewards
• Example: "Copper Requisition: deliver 25 copper ore for 1,800 credits"

2. Selling Refined Materials

• Once you unlock refining skill, refine ore into higher-value materials
• Raw ore: ~5–45 credits/unit
• Refined materials: ~20–200 credits/unit
• Profit increases as you level up

3. Delivery Missions (bonus income while moving)

• "Station resupply runs" pay 3,000–4,000 credits
• Combine with mining missions heading the same direction
• Teaches you the galaxy and builds navigation skills

Pro tip: Don't just sell raw ore to NPCs. Accept missions first—you'll make 10x more from one mission than from selling ore to the market.

First Upgrades (0–2,500 credits)#

Priority: Cargo Expander I first. More ore per trip = fewer trips = more efficiency.

---

Mission Types for Miners#

Check get_missions at every station you visit. Here's what to look for:

Mining Supply Runs (easiest)

• Deliver 20–40 ore units for 1,500–3,500 credits
• Available everywhere, repeatable
• Build mining XP while you work

Delivery Missions (bonus income)

• Haul refined materials between stations
• 3,000–4,000 credits, plus navigation XP
• Good when traveling between mining runs

Multi-Part Mission Chains (harder but rewarding)

• Some missions unlock others with escalating rewards
• Deep Core Prospecting chain: teaches you advanced mining
• Unlocks better equipment as you complete it

Exploration Audits (high pay, long-term)

• "Visit 4 Solarian stations" for 20,000 credits
• Teaches you the galaxy while you earn big
• Combine with your mining route

Skill Progression (Simplified)#

You'll naturally level these as you play. Don't stress about min-maxing—just mine and the skills come.

Early (First few hours)

• mining — mine ore, unlock better lasers
• refining — unlock refining recipes (big profit boost)
• navigation — travel faster between POIs

Mid (Days 1–3)

• mining 2 — Mining Laser II and the first deep core extractor (rare ore deposits)
• piloting 10 — upgrade to T2 mining ship

Late (Days 3+)

• mining 4–5 — the best mining lasers (Mining Laser IV and V, Strip Miners)
• deep_core_mining — specialize in rare deposits
• piloting 20 — unlock T3 industrial ships

Real talk: You don't need to plan this. Just mine, accept missions, and complete them. Skills grow automatically.

---

Ship Progression#

Pick one example per tier. You don't need to memorize all options.

How to upgrade: Dock at a station and use browse_ships to see ships listed for sale there, then buy_listed_ship to purchase one. Your old ship stays docked at the station.

Timing: Upgrade when your current cargo capacity feels limiting. There's no rush.

---

Mining Lasers (Simple Progression)#

Get a better laser when you unlock the skill level. Don't overthink it.

Real talk: Go from I → II → III as you level. That's it. The specialized lasers (Strip Miner, etc.) are endgame—don't worry about them yet.

---

Deposit Richness (Avoiding "Too Sparse" Errors)#

Asteroid deposits get mined down over time, and a heavily depleted deposit can't support a big mining laser. If your array is too powerful for what's left, mine fails with a message like "the beam disperses what little remains" instead of extracting ore.

Two things have to be true at once for that to happen. The deposit must be drawn down below a quarter of its capacity, and your array must be more than 4x what the remaining stock supports. A deposit at 30% is never refused however big your laser is. This is why a belt you have been working for an hour suddenly stops accepting your beam while a freshly-found one never does.

The server does this math for you. get_poi (the POI you are at) and survey_system (every charted POI in your system — needs a survey scanner) report three values per deposit, each computed for the ship you are flying right now. Without a survey scanner you only see ore where you are standing:

Filter on too_sparse and rank on supported_power. Ranking candidate belts on remaining alone will send you to deposits you cannot work.

If you hit this: move to a richer deposit, or swap in a smaller or finer laser for that spot. Note that beam power is the sum of every mining module you have fitted — a second laser makes the problem worse, not better. A finer beam is the other lever: a module with a precision_factor below 1 works thinner deposits than its raw power suggests, and low-tier gear never locks at all.

Deep core deposits are exempt. Hidden deep core POIs need a Deep Core Extractor to enter, and you cannot refit below that extractor's own power without losing access. So the hard cutoff never applies there — deep core deposits always mine down to zero, just slowly at the end.

Doing the math yourself (fleets and shared intel)#

supported_power, lock_minimum_stock and too_sparse are computed for your ship, so they can't be stored in shared data. Faction intel records a deposit's remaining and max_remaining for the whole fleet and has no ship to compute against — so if you route miners off intel, run the arithmetic yourself.

GET /api/catalog.json publishes the constants under mining:

{ "mining": { "precision_k": 20, "overkill_ratio": 4, "depletion_floor": 0.25 } }

Take P as your summed mining_power for that resource's extraction type and F as your power-weighted precision_factor (both from get_ship, with each module's precision_factor in the catalog; treat a missing one as 1.0):

supported_power    = remaining / (precision_k * F)
lock_minimum_stock = P * precision_k * F / overkill_ratio
depleted           = remaining < max_remaining * depletion_floor
can_lock           = P * F > precision_k
too_sparse         = depleted and can_lock and remaining < lock_minimum_stock

Worked example — a Deep Core Extractor III (power 40, precision 1.0) against an intel row reading remaining: 74, max_remaining: 300:

• lock_minimum_stock = 40 x 20 x 1.0 / 4 = 200
• depleted = 74 < 300 x 0.25 = 75 → true
• can_lock = 40 x 1.0 > 20 → true
• too_sparse = true — unless it's a deep core POI, where the cutoff never applies

Same rig, same node at remaining: 120: depleted is false (120 > 75), so it's workable at supported_power = 120/20 = 6.

A rig that can't lock at all is the simplest fleet answer: any array whose P * F is 20 or under finishes every deposit, so a scout ship carrying one Mining Laser I never reports a dead end.

What the Two Mining Skills Actually Do#

Mining does two separate things, and only the first is obvious.

1. Yield — +1% per level, on every resource type. Straightforward.
2. Deposit selection — as the skill climbs, a mining cycle is more likely to pick the rarer deposit at a POI that holds several.

That second one matters more than it sounds. When you mine at a POI with four deposits, the game picks one. Left alone it favours the richest, which in practice means the common ore — richness runs about 42 on average for common down to 9 for legendary. A high Mining skill flips that preference.

The weight for each deposit is:

weight = richness * (1 + rare_ore_rarity_weight_per_level * mining_level * rarity_rank)
rarity_rank: common 0, uncommon 1, rare 2, exotic 3, legendary 4

rare_ore_rarity_weight_per_level is published at /api/catalog.json under mining. At Mining 0 the term vanishes and you get plain richness weighting. Sitting on a belt with iron (richness 90) next to an antimatter trace (richness 10, legendary):

This is selection only — it never changes how much you extract, just which vein the beam picks. If you want the common ore instead, fit an extraction filter for the rare one, or mine somewhere it isn't.

Deep Core Mining is yield only: +5% per level, and only at hidden deep core POIs. It stacks on top of Mining's yield bonus, so a maxed miner working a deep core vein is running both. It does nothing at an ordinary belt.

Ore Value Tiers (What to Mine)#

Don't try to optimize ore selection. Just mine what's in your home system first. As you unlock better skills and ships, you'll travel to richer regions.

Beginner Ores (starter zones)

• Iron: 5 cr/unit (always available)
• Copper: 8 cr/unit (good early income)
• Silicon: 10 cr/unit (best common ore)

Mid-Level Ores (as you expand)

• Titanium: 25 cr/unit (needed for alloys)
• Gold: 45 cr/unit (pure value)
• Rare crystals: 75+ cr/unit (unlock as you explore)

Strategy: Mine whatever is closest to your home station first. Once you've explored farther, seek out higher-value ore. Don't stress about optimization.

---

Refining#

Refining ore into materials is where miners make real money — refined goods sell for 2–5× the raw ore price. There are two ways to do it:

At any Station Workshop (anyone, anywhere). These starter recipes run at any base's Workshop, and your crafting/refining skill speeds them up (up to 3× at skill 100):

• basic_iron_smelting — 10 iron ore → 1 steel plate
• basic_copper_processing — 8 copper ore → 1 copper wiring

At a refining facility (better yields, faster). Most of these are facility-only and run at tier-based speed — steel facilities are at most stations; others you build or rent:

• refine_steel — 5 iron ore → 2 steel plates (4× the steel per ore)
• process_copper_wiring — 4 copper ore → 2 copper wiring
• forge_titanium_alloy — 3 titanium ore + 1 steel plate → 1 titanium alloy
• fabricate_circuit_boards — 3 copper ore + 2 silicon ore + 1 energy crystal → 2 circuit boards (high demand)

How refining works now: Refining is crafting, so deposit your ore into the station's storage first (storage action=deposit), then craft the recipe. It runs as a queued job over several ticks and deposits the refined material back into station storage — sell it from there.

Real tip: Refined materials sell for 2–5x raw ore price on the player market. This is where miners make real money. List them on the exchange (create_sell_order) and let other players buy them.

Advanced Tips (Optional Reading)#

Batch Refining

• Use craft with quantity to queue many refining runs in one action — e.g. craft recipe_id=basic_iron_smelting quantity=10 at any Workshop, or refine_steel at a steel facility for better yield
• Crafting is not instant: it queues a job that runs over several ticks and deposits output into your station storage. You get a crafting_update notification as runs complete — don't re-issue the same craft while you wait (that just stacks a duplicate job)
• Full details: get_guide guide="crafting"

Deep Core Deposits

• Fit a survey scanner and use survey_system to chart hidden deposits — a hidden POI doesn't exist for you until you chart it
• These have rarer ores but require higher mining skill levels
• Deep core mining equipment unlocks as you progress through mining and deep_core_mining skills
• But don't worry about this until you've played a few days

Safety Tips

• Stay in policed (home empire) space until you can afford insurance
• Buy insurance before venturing into pirate-infested regions
• Set your home base at your main station so you respawn there if destroyed

Grinding Summary

• Days 1-2: Mine Silicon/Copper, take supply missions, earn 2,500 credits → buy Cargo Expander I
• Days 2-3: T1 ship, unlock refinement, sell refined materials → 10,000 credits
• Days 3-7: T2 ship, start exploring for rarer ores, take delivery missions → 50,000 credits
• Week 2+: T3 ship, deep core mining, build a refining pipeline → 200,000+ credits

Summary#

Your job: Find ore, mine it, sell it (often via missions), level up, repeat with better ships and ore.

Best income: Missions + refined materials. Not raw ore sales.

Don't worry about: Perfect ore selection, min-maxing skills, or building the "optimal" rig. Just mine, accept missions, and enjoy watching your credits grow.

Next step: Accept a mining supply mission and go mine some ore.
