What to know

  • Quartz Ore spawns only in underground cave systems, not on the surface
  • Cave access is often tied to environmental events like solar storms
  • You need proper mining tools or machinery to extract it efficiently
  • Quartz is mainly used for structural materials and progression crafting

In StarRupture, Quartz Ore is a mid-game mineral resource primarily used for advanced crafting, electronics, and structural upgrades. It’s rarer than basic ores (like Iron or Copper) and usually found in hostile or deeper zones.

Where Quartz Ore spawns underground

Quartz Ore does not appear as surface veins like Titanium or Calcium. Instead, it generates inside underground cave networks that are often sealed early on.

These caves are typically blocked by thick organic growths or vines that retract temporarily after Ruptures. Once open, you can enter and explore deeper sections where Quartz appears embedded in crystalline cave walls.

How to access underground caves safely

Most cave entrances are not immediately usable when you first spot them. You’ll usually notice a sealed opening covered in dense vines or terrain growth.

These barriers retract for a limited time after certain environmental events, so timing matters. When the opening clears, you can enter, but you should prepare for low visibility and potential threats.

How to mine Quartz Ore efficiently

Step 1: Locate a cave entrance

Explore your surroundings for blocked cave openings, often found near uneven terrain or dense growth zones. Keep an eye on the environment after solar storms.

Step 2: Enter during the open window

When vines or organic barriers retract, head inside immediately. These openings are temporary and may reseal.

Step 3: Identify Quartz veins

Inside the cave, look for blue and white crystal formations embedded in walls or clustered in chambers. These indicate Quartz Ore nodes.

Step 4: Use the right mining method

Mine Quartz using an upgraded handheld mining tool or deploy an Ore Excavator if the terrain allows. Basic tools are slow and inefficient here.

Step 5: Maintain visibility and power

Use your flashlight or portable lighting to spot crystal veins in dark tunnels, and ensure you have enough power and oxygen for extended mining runs.

What Quartz Ore is used for

After extraction, Quartz Ore must be processed at your crafting or refining stations. It unlocks Quartz-based building materials that are required for sturdier base components and higher-tier structures.

While Quartz may not always appear as a final crafting ingredient by name, it acts as a key intermediate resource for progression-focused construction.

Tips for faster Quartz farming

  • Focus on deeper cave networks rather than shallow tunnels
  • Enter caves immediately after environmental events trigger openings
  • Bring extra power, oxygen, and basic defense gear
  • Scan walls carefully—Quartz blends into cave lighting at a distance
