The Simpleores Mod for Minecraft adds five new ores to the already existing ore system as well as simple recipes to go alone with those new ores. The Simpleores Mod is meant to add familiar ore types to the game so that there's not a huge learning curve when adding this mod.
The most common item to be found is copper. The copper ore can be crafted into copper buckets as well as copper armor, which has a protection equivalence to leather armor. Silver ore can make bows that will knock enemies back further than a regular bow. Mithril ore is less rare than diamonds and can make better armor than iron. The fourth ore is adamantium and the final ore is onyx. Onyx creates stunning black armor to be used by players.
