The gold-silver-zinc mineralization at Minera Florida presents characteristics common to several deposit models but they do not fit any unique model, likely due to evolution of a long-lived mineralizing system over time. Although it displays characteristics of epithermal deposits (Moncada et al., 2015) such as structurally controlled banded and cockade textured polymetallic veins with haloes of illite alteration in a near-surface volcanic setting, it also shares characteristics with structurally controlled iron oxide-copper-gold (IOCG) and skarn deposits that indicate an intrusion- related environment, suggesting an evolution from a hot, intrusion-related setting to a cooler epithermal environment over the span of the magmatic and hydrothermal system.

Intrusion-related deposits are a broad category that encompasses the various deposit types that can be found in such an environment. Some epithermal (both high-and low-sulphidation) as well as skarn, and IOCG deposits are intrusion-related; features common to these deposit types are found at Minera Florida (Moncada et al., 2015).

In light of this, the following sequence outlines the important stages of the formation of Minera Florida deposit and is proposed as a guide for exploration for additional mineralization of this type:

- The district was affected by an early very-high-temperature regional metasomatic event caused by the transport of magmatic fluids along the steep El Roble fault and throu ........

The Minera Florida operation consists of several underground mines that are accessed via six adits. Ore is sent to a mill where it is processed at a rate of 74,500 tpm, approximately 2,450 tpd. At the current processing rate, Minera Florida has a mine life of approximately five years based on mineral reserves only. However, Minera Florida has a long track-record of replacing mineral reserves through discoveries of new deposits while maintaining approximately five years of mineral reserves. Furthermore, Minera Florida’s favourable geological environment, both near mine and regionally, provides exceptional mineral potential that may eventually result in extending the mine life beyond the mineral reserves mine life. Yamana's track-record of mineral reserves replacement and new discoveries therefore indicates the potential of extending the mine life beyond the reserves LOM and sustaining a strategic mine life of 10 years or more.

Mining at Minera Florida is conducted using various underground variations on sublevel stoping (SLS), either traditional SLS or longitudinal retreat. The different mining zones are accessed via ramps that provide flexibility and access to the ore at different elevations.

Traditional SLS is used for veins thicker than 3.5 m. With this method, production drilling is conducted from upper levels, drilling is directed downwards for benching and upwards for undercutting the back. Two parallel galleries are generally developed at the lowe ........
