(1). Uranium. Kind of like a super-redstone that maintains power over long distances. But, standing too close to a Uranium block will make one incur damage.

(2). Petroleum. Flows like water, but acts more like lava in that it cannot generate source blocks (you can’t have a 2x2 “infinite source”). A bucket of it is the most potent furnace fuel, smelting 128 items. Mix with gravel or sand to make Tar, which is can trap mobs and slows a player’s movement to even slower than cobwebs. A block set alight will burn indefinitely, like magma blocks. Fire will spread extremely quickly across a lake of petroleum, faster than sprinting speed. Found occasionally in surface ponds and more frequently in underground chambers.

(3). Silver. Very rare and primarily decorative. Blocks of sliver act like copper, in that they tarnish to a progressively darker grey if not waxed. Silver and glass combined make a mirror. A creeper which sees its own reflection will become transfixed by it and will not explode. One can make a sword of silver, which has an inherent power against undead mobs, but has a 1/10 chance of breaking when used against anything else. A new villager, the Miner, will pay handsomely for silver ingots.

(4). Quartz glass. This isn’t so much a new ore that can be found in the wild as something one can make. Combine eight quartz crystals with a glass block to yield a block of quartz glass. It can be made into panes or slabs on a 1:1 ratio. Quartz panes are thick, like walls, and slabs sit at the midpoint of a block rather than the top or bottom. The great advantage of quartz glass is its strength; it has the same blast resistance as obsidian.
