RE: RE: RE: it's close to lumina copper The Regulus website says Rio Grande is 450km west of Salta. Lumina says Taca Taca is 230km west of Salta. Comparing the maps on their websites, it looks as though they should be within 30km of each other. I wanted to post a picture of a map that I got from the Lumina website and overlaid where I see Rio Grande, but I guess you can't post pictures on this website. I'll send it to you if you pm me.
