Remember that the 14 tallest peaks in the world are over 8 km from sea level. So 4,300m is definitely not near the summit.

The article really sucks on details, but some quick googling tells me that the two base camps are above 5,100m, so this must be below even that.

Edit: the “remember” part is not condescending, just something I try to remember to give perspective on heights. And I thought it was the 8 highest peaks before fact-checking myself 😅.
