Maturity 101-103 are perfect mobs for beginners due to low HP, damage and agression. You can find them west from Zion Citadel. Higher maturity miners are located around the Madmax Outpost and attack in groups once provoked so be ready to fight several at once. All miners have a noticable health regeneration.

Suggested armor: Explorer, Voyager, Prober for lower maturities, Enhanced Prober, Enhanced Voyager, Faradon or Acidor for higher maturities.
