There is a great deal of material that I could not include in this book. Perhaps the most pertinent would be a discussion of the global mining fundamentals, particularly as they apply to producer hedging practices. Also, I have not provided a full examination of the specifics related to central bank sales. These are critical factors in any fundamental assessment of the precious metals sector. In this chapter, I provide a brief overview and urge you to do more research into global supply-and-demand statistics for gold. This information is available from the World Gold Council (www.gold.org), the International Monetary Fund, and Gold Fields Mineral Service (GFMS).
