What does Pablo Neruda refer to in the last verse of his poem "La Anaconda Copper Mining Company"?

"Y hay una y otra cruz torcida
en las laderas infernales
como única leña dispersa
del árbol de la minería."

He is talking about the sacrificed lives that are the result of the mining company's lack of care of the miners.
They are being "crucified" by the company. The only "ore" of the mine are the crosses that mark the deaths of these miners.
