Yonni's wife was there, I didn't see a mistress? I think it was Claudio Yanez Lagos who had the girlfriend and the wife there. The girlfriend didn't kiss him, but did kiss the mining minister, according to the blog.

[Updated at 6:02 a.m. ET, 7:02 a.m. Chile time] Claudio Yanez' girlfriend kissed the mining minister as he arrived at the top of the rescue chamber, becoming the eighth miner to emerge after being underground for more than two months.
Wearing glasses to protect his eyes from the change in light, Yanez ran towards his loved ones and engaged in a long embrace with his wife. He then went to hug his two daughters, the youngest who was crying and rubbing her father's back. He held his daughters as he went and thanked each rescuer one at a time.
