sulphur resource 500ktpa pyrite concentrate

I see reading the preso that the WRP as well as the main polymetallic resource also has a resource of 2mt of Sulphur in the form of pyrites and that they propose producing 500ktpa of pyrite concentrate.

Given the global price of sulphur and sulphuric acid (the latter which can be made from pyrite concentrate as I understand it) this could be quite an important boost to the project economics.

Anyone able to indicate a value here per ton of concentrate?

I just wonder if they are thinking of processing on-site to make the acid.

TRO is on my short-list with hopefully good news due soon on WRP BFS etc.
