I want to add many very similar ores to the game, so I created an Enum and a Block with a PropertyEnum to serve as the "base" mod ore block. Code:

public class BlockModOre extends Block implements IMetaBlockName{

	public static final PropertyEnum TYPE = PropertyEnum.create("type", Ores.class);
	
	
	public BlockModOre(Material materialIn) {
		super(materialIn);
		this.setUnlocalizedName("ore");
		this.setRegistryName(new ResourceLocation(Reference.MODID, "ore"));
		this.setCreativeTab(Atomic.tab);
		this.setDefaultState(this.blockState.getBaseState().withProperty(TYPE, Ores.BAUXITE));
		this.setHardness(3);
		this.setResistance(15);
	}
	@Override
	public int getMetaFromState(IBlockState state) {
		Ores type = state.getValue(TYPE);
		return type.getID();
	}
	@Override
	public IBlockState getStateFromMeta(int meta) {
		return this.getDefaultState().withProperty(TYPE, Ores.values()[meta]);
	}
	@Override
	protected BlockStateContainer createBlockState() {
		return new BlockStateContainer(this, new IProperty[] {TYPE});
	}
	@Override
	public void getSubBlocks(CreativeTabs itemIn, NonNullList<ItemStack> items)
    {
		for(int i = 0; i < Ores.values().length; i++) {
			items.add(new ItemStack(this, 1, i));
		}
    }
	@Override
	public String getSpecialName(ItemStack stack) {
		return Ores.values()[stack.getItemDamage()].getName();
	}
	@Override
	public ItemStack getPickBlock(IBlockState state, RayTraceResult target, World world, BlockPos pos, EntityPlayer player) {
        return new ItemStack(Item.getItemFromBlock(this), 1, getMetaFromState(world.getBlockState(pos)));
    }
	@Override
	public int damageDropped(IBlockState state) {
        return getMetaFromState(state);
    }
}

All these block have the same Hardness and Resistance, the same for all ores, but some require different levels of pickaxe to harvest them. The blocks are initialized through this method in ModBlocks:

public static void init(RegistryEvent.Register<Block> event) {
		for(Block b : blocks) {
			if(b instanceof IMetaBlockName) {
				ModItems.addItemBlock(b, new ItemBlockBase(b));
			}
			else {
				ModItems.addItemBlock(b);
			}
			event.getRegistry().register(b);
		}
	}

The "Ores" enum has a property which contains each ore's harvest level, but I cant see where to place the typical setHarvestLevel("pickaxe", HARVESTLEVEL). Thanks in Advance! (Everything else about the block works perfectly right now)

...override getHarvestLevel?

Thank you for pointing me back in that direction. I had originally searched there but skipped this method because my real question was how to access this block's state from within its own class. Turns out getHarvestLevel takes the state as a parameter, allowing me to access it that way. Thanks!

Blocks are singletons, there's only one instance per block type. This means that a Block can't have a single IBlockState, BlockPos or World field, since a Block can have any number of valid states at any number of positions in any number of dimensions. Instead, any method that needs access to the these receives them as parameters.
