What professionals say about us

Juan Cantus, Analyst at Cobas Asset Management

I particularly appreciated the technical analysis of the Geology, Mining, Metallurgy and Regulation/Permitting sections of the Sigma report. This is exactly what we look for at Cobas as a generalist value manager: a thorough review and in-depth analysis of the technical assumptions underlying mining projects. I believe you can add significant value for investors seeking exposure to the mining sector.

Adrián Godás, Consultant at FastMarkets

I found the Sigma report to be very, very good. There is no doubt that the team behind Truth Below Ground is top-tier. The mining sector will benefit from their independent and rigorous analysis.

Timothy Chilleri, Commodities Analyst

I have become a regular reader of Truth Below Ground since their launch. Their reports are a tremendous addition to my own research. Detailed and thorough reports getting to the core of what I care about, which is what’s the comprehensive risk/reward in this situation? I recommend it for investors who value third party independent research.

Aurora Davidson, CEO at Amerigo Resources
