Adamantite Ore

Adamantite is a new type of ore which will make an appearance in an upcoming update, 1.1. The ore was confirmed on a video that was posted on YouTube by Redigit. In the video, it seems that in order to get Adamantite, the player will have to break down a Demon Altar (which can be breakable in the upcoming update). This also applies to other new types of ores, such as Cobalt and Mythril. This was proven when a text appears when a Demon Altar was broken that says "Your world has been blessed with Adamantite!"

According to the name of some of the items used in the video, it seems that it can be crafted into Adamantite Drill, Adamantite Chainsaw and Adamantite Glaive. It might also be used to craft the red armor shown in the teasers, due to it being of similar colour to the items.
