Yes, they may eventually receive the companionship of the Holy Ghost, but only after a tremendous amount of suffering, as the Lord explained in D&C 19:15-20.

All of the various gradations and degrees of inherited glory are eventual; in the meantime, those who fully repent and strive to obey with all their hearts will be received into a state of happiness at their death, to await their eventual exaltation and glory. All others will suffer the punishment for sins for which they failed to repent. In D&C 19:15-20, the Lord spells out in limited detail what is involved. These verses paint a vivid picture for any who think that anything less than complete repentance is an option:

“15 Therefore I command you to repent—repent, lest I smite you by the rod of my mouth, and by my wrath, and by my anger, and your sufferings be sore—how sore you know not, how exquisite you know not, yea, how hard to bear you know not.

16 For behold, I, God, have suffered these things for all, that they might not suffer if they would repent;

17 But if they would not repent they must suffer even as I;

18 Which suffering caused myself, even God, the greatest of all, to tremble because of pain, and to bleed at every pore, and to suffer both body and spirit—and would that I might not drink the bitter cup, and shrink—

19 Nevertheless, glory be to the Father, and I partook and finished my preparations unto the children of men.

20 Wherefore, I command you again to repent, lest I humble you with my almighty power; and that you confess your sins, lest you suffer these punishments of which I have spoken, of which in the smallest, yea, even in the least degree you have tasted at the time I withdrew my Spirit.”

True it is that all but the sons of perdition will eventually be saved in a kingdom of glory. However, the price that all unrepentant souls will have to pay to reach that far off salvation can rightly be spoken of as hell, and such is the precious language of the Book of Mormon.
