Perhaps this Chinese company can help us in the future. This company owned concessions bordering the Tesoro in the past, and may still do today? It is also interesting to see them have projects in the same areas as our Cueva Blanca and Vilcoro as well. You may wish to look at some of the geophysical pictures of their mines for comparison with the Tesoro geophysics. I guess the main comparison is, that when you have geophysical signatures like we do on the Tesoro, it is a mine with impressive volume. :)
