Global Gold Mines and Deposits Ranking 2012

Very interesting report

Intro:

Following on the success of last year’s report we have decided to make the ranking of the world’s gold deposits an annual endeavor highlighting trends in future mine supply, depletion, discoveries, and in-situ grades.
As far as we know, there has not been a similar effort to compile a comprehensive database of the world’s gold mines and deposits. Nevertheless, we rose to the laborious challenge as we knew that the industry reliance on risk capital via public markets presented an opportunity to data mine regulatory filings which would result in a high quality database.
With this research our goal was to provide quantitative answers to some of the questions we kept asking ourselves as investors in the space. Questions such as:
How many ounces of in-situ gold exist?
How many gold mines exist in Canada?
How rare is a 1.0 million ounce undeveloped deposit?
The report answers these questions and more while providing insight into the scarcity of mines & deposits. Additionally, having a granular view of the supply mix is useful as it allows market participants to ascertain the long-term supply and demand fundamentals of the metal.
We have made some important changes this year to the methodology of the database adding grade, tonnage, and government owned mines/deposits. We also partnered with Visual Capitalists, an investor website that provides rich visual content, to assist in visualizing the data we compiled. The report is free for usage and distribution with acknowledgment of the author.
