Ann: LRS Operations Update, page-131

I am no economist either desafortunadamente.

It is in my understanding that the mining tax rate in Argentina is 35% + a 3% royalty tax so yeah around 40%

We will not know the real project costs until (if) a resource is identified and a PFS is completed.

However you can rest assure that any future changes while possibly encouraging mining in Argentina. Will be put in place to benefit the local economy well before any companies or to benefit LRS.
They will not allow their country to be drilled out and see all the money go offshore.

We have seen negative changes in the laws surrounding tax and loyaltys for mining companies in Tanzania and in the Congo, effecting graphite and lithium stocks already in the last fiscal year.

With the sector still having some growing to do I would think there will be more taxes and royalties to come.
