# Mining

Mining is a core mechanic in **Outpost Surge**, allowing players to gather essential resources for survival and expansion. Resources on Mars are divided into two categories: **Above-Ground Deposits** and **Below-Ground Deposits**, each with distinct mechanics.

***

### Resource Types

#### Above-Ground Deposits

Found on the surface of Mars, these resources are limited in supply and must be utilized efficiently.

* **Types of Resources**:
  * **Ice**: Used for water production.
  * **Ore**: Used in construction.
* **Key Characteristics**:
  * Deposits are finite and deplete once fully mined.
  * Randomly distributed within a set radius of the Command Center.
  * Placement rules ensure deposits are spaced out to prevent clustering.

#### Below-Ground Deposits

These resources are located underground and provide an unlimited supply, but they require advanced infrastructure to access.

* **Types of Resources**:
  * **Ice**: Extracted for water.
  * **Ore**: Extracted for construction.
* **Key Characteristics**:
  * Require specialized extraction buildings, such as Ice Mining Plants and Ore Processing Plants.
  * Gated behind research in future versions of the game.

### Mining Methods

#### Manual Mining

Assign astronauts to mine surface deposits directly. This method is less efficient and slower than using dedicated mining buildings.

* **Key Mechanics**:
  * Astronauts transport mined resources back to the Command Center.
  * Astronaut needs (food, oxygen) reduce their overall efficiency.
* **Strategic Use**:
  * Useful for early-game resource collection before automated buildings are constructed.

#### Mining Buildings

Automated structures that improve mining efficiency by collecting resources within their range.

* **Key Mechanics**:
  * Extract resources from all deposits within a defined hex radius.
  * Require power to function and provide support for assigned astronauts (food, oxygen refills).
  * Operate similarly to Gathering Posts in other strategy games, centralizing resource collection.

#### Below-Ground Extraction

Advanced mining operations requiring specialized buildings for unlimited resource extraction.

* **Key Mechanics**:
  * Extractors are placed directly over underground deposits.
  * Require power and a crew of astronauts to operate efficiently.
  * Crew needs are managed within the building, minimizing downtime.
  * Extraction rates remain consistent but are limited to the building’s capacity.

### Research Gating

**Future Features**:

* **Underground Extraction Unlocks**:
  * Ice Mining Plants and Ore Processing Plants will be gated behind research, adding a progression element.
* **Advanced Upgrades**:
  * **Material Sciences**: Unlock machinery for faster extraction rates.
  * **Energy Efficiency**: Reduce power consumption of extraction buildings.
* **Strategic Depth**:
  * Players will need to balance research priorities with immediate resource needs.

### Strategic Tips for Mining

1. **Optimize Early Resource Collection**:
   * Use manual mining to gather resources quickly in the early game.
   * Transition to automated buildings as soon as possible to improve efficiency.
2. **Plan Generator Placement**:
   * Ensure mining buildings are within generator ranges to maintain consistent operations.
3. **Prioritize Research**:
   * Focus on unlocking underground extraction for a steady, long-term resource supply.
   * Invest in energy efficiency to sustain high-power operations without excessive fuel use.
4. **Expand Strategically**:
   * Build extraction infrastructure near critical deposits to minimize transportation time.
   * Consider the hex radius of mining buildings to maximize resource collection.

By mastering these mining mechanics, you can ensure a steady flow of resources to support the growth and survival of your outpost in the harsh Martian environment.
