I get a chuckle from the term “lost tribes” after all who lost them? Certainly they are not “lost” to God. He knows where each of them are at right at this very moment. And He is making ready the 12,000 of each tribe that He will call to evangelize at the end of days. Revelations 7:4-8
Amos 9:9 For, lo, I will command, and I will sift the house of Israel among all nations, like as corn is sifted in a sieve, yet shall not the least grain fall upon the earth.
