Campo Morado encompasses one of the largest polymetallic mineral systems in Mexico. Several zinc-copper-silver-lead-gold deposits and at least 16 known massive sulphide occurrences are hosted within a belt that trends northeast-southwest.

La Reforma was the first deposit discovered on the property. Reforma was mined on and off for a total of 20 years from 1898 to 1940, financing parts of Mexico's revolution. The coin used today in Farallon's logo originated from mining at Campo Morado during these historic Mexican times.

The region lay dormant until 1995 when Farallon optioned the property. Since that time, Farallon has drilled over 220,000 metres of diamond drilling as well as numerous other studies to explore and develop the Campo Morado project. This commitment has resulted in the discovery or delineation of five deposits and numerous other occurrences on the property; a number of these targets have yet to be fully explored.

Of all the discoveries made, the most significant is the G-9 deposit. G-9 is the highest grade discovery at Campo Morado to date. With over 120,000 metres of diamond drilling on the G-9 alone, the structure of the deposit is gradually revealing itself. Testing has also shown the deposit is coarse grained and has favourable metallurgical characteristics. Hence, G-9 is considered to be the "engine" that will lead Farallon into production and all work is currently focused on advancing the project towards opening in July 2008.
