minetest-mod-moreores 0~20130828+git0977bbc809-1.1 (amd64 binary) in ubuntu hirsute

 This mod adds copper, tin, silver and gold in Minetest. This mod also
 adds three new sets of tools/swords.

 All these five ores give lumps upon mining - those lumps are smeltable
 into ingots, then you can do tools, blocks, and locked chests out of
 them.
